FTTH
Primus IT is committed to the research and development of PON technology and provides the best solution for the realization of FTTH. Primus IT can cooperate in the development according to the special requirements of customers, and provide customers with a complete set of FTTH solutions based on a complete product line. FTTH Fiber to the Home China FTTH (Fiber to the home) is a transmission method of fiber communication. Specifically, FTTH refers to the installation of optical network units (ONU) at home users or corporate users and is the type of optical access network application that is closest to users in the optical access series except for FTTD. The notable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths, and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation. Advantages of FTTH technology 1. Very large transmission medium and speed and high bandwidth. 2. Its bandwidth is relatively wide, and the long distance is exactly in line with the large-scale use of operators. 3. Easy and fast installation. 4. Low-cost maintenance. 5. Low losses in network. 6. Enhance the transparency of the network to the data format, rate, wavelength and protocol. 7. Relaxed requirements on environmental conditions and power supply. 8. Increased reliability of broadband transmissions in comparison to other networks, either today or in the future. Applications of FTTH service FTTH is a comprehensive access solution for all services. Although the main driving force of FTTH is broadband video services in the future, FTTH must be able to support a variety of existing narrowband and broadband services, as well as possible new services in the future. FTTH system must be able to provide integrated access, so that users can enjoy multiple services at the same time. PON technology, especially EPON, is widely used in the access network. It promotes the simplification of the network level, makes the network structure clear, management and maintenance more convenient, and greatly reduces the cost of computer room, electricity, and maintenance. The current access network construction is widely implemented by EPON, and common networking methods include FTTB+LAN, FTTB+EOC, and even FTTH. In the past, EPON devices were mostly independent box-type devices with low port density, low capacity, and simple business functions. Now, operators mostly adopt integrated equipment that combines EPON and Layer 3 switches, especially the integration of large-capacity, multi-function switches. EPON is inserted into the chassis of the switch as a plug-in card (multiple EPON modules can be inserted), so that the OLT part of EPON and the aggregation layer switch are integrated, which further simplifies the network structure. Another advantage of this is to make business processing more flexible and convenient, such as flexible QinQ technology, VLAN three-layer termination, and even MPLS VPN services. At present, the integrated equipment with the highest business performance can provide 160 PON ports, which fully meets the operators’ high-bandwidth and large-capacity access requirements. FTTH telecom development In the optical access family, there are FTTB (Fibre To The Building) fiber to the building, FTTC (Fibre To The Curb) fiber to the roadside, FTTSA (Fibre To The Service Area) fiber to the service area, and so on. When the optical fiber is directly connected to the user's home, there are no restrictions on its bandwidth, wavelength and transmission technology. it is suitable for the introduction of various new services. it is the most ideal service transparent network and the ultimate way for the development of access network. Although the development speed of mobile communication is amazing, because of its limited bandwidth, the terminal volume can not be too large, the display screen is limited and other factors, people still pursue the fixed terminal with relatively superior performance, that is, they want to achieve fiber to the home. The charm of fiber to the home lies in its great bandwidth, which is the best way to solve the "last kilometer" bottleneck from the Internet backbone to the user's desktop. With the upgrading of technology, the cost of fiber to the home is greatly reduced, which will soon be comparable to DSL and HFC, which makes it possible to make FTTH practical. In addition, FTTH technology is also used to solve the "last kilometer" problem in the information superhighway. FTTH+ Ethernet is much faster than ADSL and ISDN. Primus lT is a professional ftth manufacturers, we provide ethernet transceiver, ftth in china, 10g ftth, ftth 1gb, ftth 10gb, ftth broadband speed test, interconnect etc. Want to know ftth connection cost or more?

EPON refers to an optical fiber access system. The ONU is the terminal device of the system, which can be used to connect to computers of home users and devices of industrial users. Two functions of our 10g EPON ONU: selectively receive the broadcast sent by OLT; collect and cache the Ethernet data that needs to be sent, and send the cached data to the OLT terminal according to the allocated sending window; effectively improve the uplink bandwidth utilization rate of the whole system, and configure the channel bandwidth according to the network application environment and the characteristics of applicable services; can carry as many end users as possible without affecting the communication efficiency and quality, improving the network utilization rate and reducing the user cost. What is 10g EPON(GEPON) OLT ? EPON (Ethernet Passive Optical Network), has the characteristic of saving optical resources and is transparent to network protocols. EPON uses a single optical fiber to connect the OLT, and then the OLT connects the ONU. The 10g EPON OLT device is an important local device. It can be connected to the switch at the front end by using internet fibre 10g epon cables and connected to the optical splitter at the client end by using a single optical fiber. Fibre techno 10g epon can realize the control and management of the client device. Like the ONU equipment, it is also a photoelectric integrated equipment. EPON vs. GPON vs. 10G-EPON EPON is a kind of PON network. The EPON network consists of OLT, ODN, and ONU. The main features are point-to-multipoint, passive line, simple and clear network layer, providing comprehensive access to voice, broadband, CATV, etc. The EPON system uses upstream and downstream symmetric transmission with a nominal rate of 1.25 GB. The STANDARD of EPON is IEEE 802.3AH, which is based on gigabit Ethernet technology and realizes PON point-to-multipoint transmission through point-to-multipoint control protocol (MPCP) on MAC layer. The protocol is simple to implement, but the OAM capability is relatively weak. While the STANDARD of GPON is ITU-T G.984 series, which follows the standard protocol framework of APON and adds GEM, a new frame encapsulation method of TC layer. It has strict regulations on QoS and OAM, and has a strong capacity to carry TDM services and relatively complex protocol. GPON has a high transmission rate and shunt ratio, providing TDM services with high timing accuracy. As for the internet fibre techno free 10G-EPON, it is developed on the basis of EPON, and the two are basically the same in technical principle, but the free 10G-EPON has a stronger carrying capacity.

SFP interconnect cable overview The GBIC module is divided into two categories: one is the ordinary cascade GBIC module, which realizes the common connection with other switches; the other is the stack special GBIC module, which realizes the redundant connection with other switches. GBIC is basically replaced by SFP for the following reasons: SFP (Small Form-factor Pluggables) can be simply understood as an upgraded version of GBIC. SFP module (half the size of the GBIC module, you can configure more than twice the number of ports on the same panel. Because the function of SFP module is basically the same as that of GBIC, it is also called miniaturized GBIC (Mini-GBIC) by some switch manufacturers. The SFP module further reduces the size and power consumption by placing CDR and electric dispersion compensation on the outside of the module. Used in optical communication applications in telecommunications and data communications. SFP connects the motherboard and fiber or UTP cables of network devices such as switches, routers, and so on. SFP is an industrial specification supported by some optical fiber device providers. SFP supports SONET, Gigabit Ethernet, fibre Channel (Fiber Channel), and other communication standards. This standard extends to SFP+, to support 10.0 Gbit/s transmission rates, including 8 gigabit fibre Channel and 10GbE. The optical fiber and copper core version of the SFP+ module is introduced. Compared with the Xenpak, X2 or XFP version of the module, the SFP+ module leaves part of the circuit implemented on the motherboard rather than in the module. Applications of sfp interconnect Sfp interconnect cable is the main type of high-speed IO interface interconnection system that has long been used to connect servers, storage, switches, video and communication systems. The main market segment implementations include cloud data centers, enterprise data centers, HPC (High performance Computing) labs, camera surveillance systems, and so on. FP interconnection system is developed from HSSDC (High Speed Serial data Connector). HSSDC-1 and HSSDC-2 break with the traditional use of two-piece metal connector contact systems because plug connectors use PCB with gold- plated pads to match the metal contacts of edge socket connectors. Compared with the previous very large, heavy and wide parallel IO interface connectors and cables, modern sfp interconnect cable is more convenient and efficient. SFP is also used for 2.5, 5, and 8 Gbps data rate applications, including InfiniBand standard single-channel links.

Primus IT offers high-quality modules to meet the demand of datacom and telecom networks and toenable the next generation of optical transceivers. Telecom network operation The downstream optical module is mainly used in the three major scenarios of telecommunications bearer network, access network, data center and Ethernet. The telecommunications bearer network and access network belong to the telecommunications operation market. Among them, wavelength division multiplexing (xWDM) optical modules are mainly used for medium and long- distance telecommunications bearer networks, and optical interconnects are mainly used for backbone networks and long-distance core networks. Capacity transmission; and the access network market is the "last mile" from operators to users, including fiber-to-the-home passive optical networks (FTTH PON, PON optical modules currently have a maximum transmission rate of 10Gbs), wireless fronthaul (5G optical modules, The current maximum transmission rate is 25Gbs) and other application scenarios. What is telecom network infrastructure The telecommunication network is composed of three parts: core network, access network (AN) and customer premises network (CPN). The core network and access network belong to the public telecommunication network, CPN is a user-owned communication network, and traditional CPN is a single user. One side of the access network is the core network, which is mainly composed of various business networks, and the other side is the user. The access network serves as a link between the previous and the next, and provides the services of the core network to users through the access network. The access network is a transparent transmission system that does not provide services by itself. User terminals cooperate with the core network to provide various services. Fundamentals of telecommunications and networking for it A telecommunication network is a system that organically connects various telecommunication points and telecommunication circuits. It is composed of three parts: terminal equipment, switching equipment and transmission equipment. The first two constitute telecommunication points; transmission equipment constitutes telecommunication circuits. 1. According to different business types and communication methods, it can be divided into telephone communication network, telegraph communication network, data communication network, user telegraph communication network and fax communication network. 2. According to different communication ranges, it can be divided into international telecommunication networks, domestic telecommunication networks, long-distance telecommunication networks, intra-city telecommunication networks and rural telecommunication networks. 3. In terms of the nature of use, there are private telecommunication networks and public telecommunication networks. The private telecommunications network is only available to certain professional users, such as the private telecommunications network of railway, military and other departments; the public telecommunications network can be used by ordinary citizens. 4. From the way of signal transmission, it can be divided into analog communication network and digital communication network. The relationship between data communication and telecommunication Data communication is a new communication method produced by the combination of communication technology and computer technology. To transmit information between the two places, there must be a transmission channel. According to the different transmission media, there are wired data communications and wireless data communications. But they all connect the data terminal and the computer through the transmission channel, so that the data terminals in different locations can share software, hardware, and information resources. Telecommunications is now the main form of communication, and its main task is to use wired electricity, radio, light, etc. to transmit information such as symbols, text, images, and language. Since telecommunications use electric waves to transmit information, terrain obstacles, solar activity, etc., sometimes affect the quality of communication.

Cable Harness
What is Cable Harness A cable and wire harness also referred to as a wire harness, wiring assembly, cable assembly or wiring loom, is an assembly of electrical cables or wires which transmit signals or electrical power. The cables are bonded together with a durable material such as vinyl, rubber, electrical tape, conduit, a weave of extruded string, or a combination thereof. Commonly used in automobiles, car, and construction machinery, cable harnesses has several advantages over loose wires and cables. Application and environment are the two major factors that determine the types of the wire harness. Based on these two factors, there are 3 types of harness cable assembly. Open Bundle: The cable and harness assembly is attached to the connectors and lugs and are coupled in bundles with various breakouts using plastic tie wraps or waxed lacing twine. Closed Bundle: Wires are bundled with a covering, such as pulled-on braided tubing, braided-on Nomex or nylon, or in some cases, metal braid. Waterproof Harnesses: The junctions between the legs and backshells of the connectors are molded with a material such as urethane or rubber compounds. Specifications of the Cable Harness Material Wires can be UL/CSA,CE, VDE,SAA,CB etc Size Range Thousands of different connectors available Color Black or OEM color Voltage rating: 30V AC/DC Withstanding voltage: 200V AC/minute Temperature range: -25 -85°C Insulation resistance: ≥100MΩ Design ability We can supply sample, OEM&ODM is welcome (Design, Engineering, Photographing, Sample, Production) Simple Crimped Cable Assembly: 0.8mm pitch, 1.0mm pitch, 1.25mm pitch, etc. Cable length: customized Sample Sample can be provided for evaluating MOQ Small order can be accepted Delivery Time Enough stock and strong production capacity ensure timely delivery Packaging 100/200/300/500/1000PCS per bag with label, export standard carton Application Industrial and Car audio harness Components of Cable Harness Wire The role of the wire is to carry current to convey signals and provide power. It itself contains internal copper wires and external insulating materials. Commonly used specifications have a nominal cross-sectional area of 0.3, 0.5, 0.85, 1.25, 0.3, 0.5, 0.8, etc. Wires, each of which has a current value that allows the load, and reasonable use of electrical equipment for different powers, is the basis for a qualified harness. With the increase of the functions of automobiles, the widespread use of electronic control technology, more and more electrical components, more and more wires, the thicker and heavier the wiring loom harness assembly becomes. In the future, the use of wires will be reduced, and modern cars have introduced CAN bus configurations using multiplex systems. Compared with the traditional point-to-point configuration of the wiring harness, the CAN bus greatly reduces the number of wires and connectors, making the cable and wire harness lighter and not limited. Connector and Terminal After the terminal and the electric wire assembly are crimped according to the standard, they are locked in the slot of the connector, and the male and female connectors are butted to meet the loop between the harness and the harness to the terminal. If it is arranged in the high humidity environment of the engine compartment, according to National regulations require that waterproof plugs be added. Exterior Parts and Other Components The exterior parts include a bellows, a polyethylene tube, a polyethylene cloth, a sheath, a sponge, a tape, a wire fastening harness bracket, etc., in order to place the wire to wear and break. Meet the temperature and humidity requirements of different positions of the body. Generally, corrugated pipe, polyethylene pipe, polyethylene cloth, hard pipe, and sheath are used to prevent the wire from being worn and broken. The wire is wrapped with thin- walled and thick-walled tape, and the wire harness is fixed at a suitable position in the vehicle body by using clips of different shapes. The purpose of the rubber ring is to prevent the wire cable harness from being scratched when it passes through the gold hole.

Membrane Switch
A flat membrane switch or more precisely a standard membrane switch assembly is comprised of several flexible layers that make up a complete switch package. This assembly can have as few as one active area (key or button) to several dozen active areas. A custom membrane panel switch is an interface between man and machine, which enables an operator to communicate with equipment, instrumentation, or machinery. Subsequently, this allows the operator to communicate with the device, issuing commands and/or performing other operations. The operator presses the membrane control panel when he or she wants to control the device. Construction of Membrane Switch Graphic Overlay – PET/PC is usually the overlay material of choice due to its fantastic chemical resistance and flex property. Komkey offers membrane switch customized design services such as digital printing, screen-printing, or apply both methods to ensure you get the right colors, textures and finish your membrane switch design requirements. Adhesive Overlay – This adhesive layer sticks the membrane switch overlay to the top circuit layer, and is usually an acrylic adhesive. The material is the same as the fourth layer. Only the thickness is maybe different according to the actual situation. Top Circuit Layer – The material of this layer is specific. It is a 0.1mm thickness thermostable PET film printed with conductive silver ink and also dielectric oil, which used for fastening metal domes. Circuit Spacer – This layer separates the top circuit from the bottom circuit so that the touch membrane remains normally break until the membrane switch keypad is pressed. The circuit spacer is a polyester spacer with adhesive on both sides. Lower Circuit Layer – This layer is a 0.1mm-0.25mm thickness thermostable PET film printed with conductive silver ink and also dielectric oil. This layer terminates as a flexible tail that serves as an interconnector to controller PCBs or other IC. Rear Adhesive – This adhesive layer bonds the entire membrane switch to the product surface, housing, or to a rigid support panel.

We also offer special ultraviolet selective textures and ultraviolet hard coat treatments which can protect lens areas from chemicals and scratching. How to Design the Graphic Overlay? Sample: Provide drawings of graphic overlay prototypes that all dimensions and physical characteristics including colors or actual samples for copy are clearly shown. Colors: Identify the colors which you want your switch overlays to have by Pantone (PMS) RAL color number or a color sample. It is important to supply the exact standard for which our color match will be evaluated. Borders and Outlines: Avoid circles within circles, or outlines which are close to cutouts or outer edges because any misregistration will be visually accentuated. File Format: It's best to receive design files from the native software packages. (ie Adobe Illustrator, Corel Draw or PDF files) Background: Light text and dark backgrounds will show less wear and dirt and greater clarity. Try making the control panel overlay or the membrane overlay drawings clear. Text: Block lettering provides the most legible copy. Try to use common fonts. Positive letter strokes should be a minimum of .008'' and .012''for negative letter stroke.
