MTP/MPO Loopback

T & S MTP / MPO fiber loop is a device used for parallel connection tests
and an aging test of optical communication equipment. Well-designed by
engineers at T&S, our MTP/MPO loopback adapter can transmit the optical
network signal from the transmitter to the receiver, thereby forming the
optical signal receiving and transmitting loop. MTP / MPO fiber loop
provides a fast and efficient way to test the transmission capacity and
receiving sensitivity of optical network equipment. T & S MTP / MPO fiber
loop has 8F, 12F, 16F, 24F, 32F channels with low loss and conventional
loss, single-mode and multi-mode options. Our MTP/MPO loopback adapter is
now widely used for optical network equipment self-test, network diagnosis,
and test, etc.

MTP Loopback with Housing and Pull-tab 
The MTP loopback occupies both ends of fiber in a duplex connector or a
multi-fiber connector. This MTP lookback with housing and pull-tab can
provide an effective solution so as to test the emission ability of the
network equipment and receive sensitivity. Especially in 40/100G network
communication, our MTP loopback devices can achieve optical fiber network in
pairs on a single element or interface and conduct effective tests and
evaluation of the Internet through back signal positioning.
