24F MTP OM3 Fiber Optic Loopback Module /Cable

The MTP loop contains the MTP back ring jumping line in the LOOPBACK, and puts both ends of the fiber into an MTP connector to achieve the light path in the same connector. The launch capacity and receiving sensitivity of the device, especially in 40/100G network communication, can locate various potential phenomena by returning signals to achieve effective testing and evaluation of a single coMTPnent or interface on the fiber network.

The MTP loop contains the MTP back ring jumping line in the LOOPBACK, and puts both ends of the fiber into an MTP connector to achieve the light path in the same connector. The launch capacity and receiving sensitivity of the device, especially in 40/100G network communication, can locate various potential phenomena by returning signals to achieve effective testing and evaluation of a single coMTPnent or interface on the fiber network.

There are many configurations of optical fiber circuit, which can accommodate 8 -core, 12 -core and 24 -core MTP connector and several fiber fiber configurations to adapt to the port in the test.8F MTP Fiber Loopback Module allows verification and testing of transceivers featuring MTP interface – 40GBASE-SR4/CSR4 QSFP+ devices. 12F MTP Fiber Loopback Module allows verification and testing of transceivers featuring MTP interface – 40GBASESR4 QSFP+ or 100GBASE-SR4 devices. 24F MTP Fiber Loopback Module allows verification and testing of transceivers featuring MTP interface – 100GBASESR10 CXP/CFP devices.

MTP Loopback modules provides a looped signal to test the transmit and receiving functions. It used widely within testing environment especially within parallel optics 40 and 100G networks. Loopbacks are built to link Transceivers (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.

OMC offers a line of MTP fiber optic loopback assemblies for burn-in and testing of MTP network coMTPnents and systems. These MTP Loopback Assemblies are used to effectively test transmitter capability and receiver sensitivity of network equipment, particularly for telecom and datacom requirements. They are packaged in a compact housing for the highest density available for these applications.

Fiber Optic Loopback Testing :

Typically, a loopback test is a test in which a signal is sent from a communication device and looped back to the device as a way to determine whether it is functioning well or as a way to troubleshoot a defective node in the network. As for fiber optic loopback testing, optical loopbacks are used to verify the operational reliability of the device. Using fiber optic loopback cable or fiber optic loopback module for data transmission, the signal emitted by the device is looped from the transmit (Tx) end of an active component back to the receive (Rx) end of the same component.

Application:

When it comes to practical application, fiber optic loopback test is often employed for checking fiber optic transceivers. Since transceiver has two ports for receiving and transmitting the light signal, it is necessary to test the ports to see whether they are still under operation. Thus, fiber optic loopback test is the most convenient way for transceiver maintenance. The testing process is by routing the laser signal from the transmitter port back to the receiver port. Then the transmitted pattern is compared with the received pattern to make sure they are identical and have no error.
