Name: MTP®/MPO LOOPBACK Adapter
Brand: T&S Communication Co, Ltd.

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 adapter 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.

MTP®/MPO Lookback Adapter Applications

MTP®/MPO Loopback Adapter is used widely in testing applications within parallel optical 40Gbps and 100Gbps networks. The MTP® loopback adapters enable verification and test of transceivers with MTP®/MPO interface like 40Gbps BASED SR4 QSFP+. MTP loopback adapters are developed to connect transceivers and a receiver port of the MTP®/MPO transceiver interface. MTP®/MPO loopback adapters do a great help in speeding up IL test of optical networks section by connecting them to an MTP®/MPO trunk.
