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. MTP® / MPO fiber loop has 8F, 12F, 16F, 24F, 32F channels with low loss and conventional loss, single-mode and multi-mode options. And our MTP®/MPO loopback adapter is now widely used for optical network equipment self-test, network diagnosis, and test, etc.
Fiber optic loopback tester is designed with a protective casing for the fiber optic cable, preventing bending or breakage and enhancing the adapter’s durability during tests. MTP fiber optic loopback utilizes MTP connectors for a high-quality polish, which allows for an accurate assessment during insertion loss testing of optical network segments.
The compact nature of the Loopback, along with a convenient push-pull design, makes for easier insertion and removal, thereby helping speed up the testing process in Telecom and Datacom applications.
By looping back the connections from the transmit pairs to the receive pairs in network devices, the MTP Loopback creates a complete optical link. This allows you to evaluate the performance of specific components of a network, or the complete link in a network path.
MTP® loopback modules are used widely within testing environment especially within parallel optics 40/100G networks. Devices allow verification and testing of transceivers featuring MTP® interface – 40G PLR4 or 100G PSM4 devices. Loopbacks are built to link Transmitter (TX) and Receivers (RX) positions of MTP® transceivers interfaces. MTP® loopbacks can facilitate and speed up IL testing of optical networks segments by connecting them to MTP® trunks/patch leads.
Male and female connector types are available. Choose between standard, ‘Elite’ and ‘Super Elite’ ferrule styles to minimize insertion loss and provide better testing performance.
