24 Fibers MTP Singlemode Fiber Optic Loopback Module with High Return Loss for 40G/100G Networks

The MTP loopback contains an MTP connector with both ends of the fiber terminated within the same connector, creating a looped light path. This configuration enables testing of device launch capacity and receiving sensitivity, particularly in 40/100G network communications. By returning signals to the source, it helps identify various network phenomena and facilitates effective testing and evaluation of individual components or interfaces within fiber optic networks.

Available in various configurations accommodating 8-core, 12-core, and 24-core MTP connectors with multiple fiber configurations to adapt to different test port requirements. The 24F MTP Fiber Loopback Module specifically allows verification and testing of transceivers featuring MTP interface - 100GBASESR10 CXP/CFP devices.

MTP Loopback modules provide a looped signal to test transmit and receiving functions. They are widely used within testing environments, especially in parallel optics 40G and 100G networks. Loopbacks are designed to link Transceiver (TX) and Receiver (RX) positions of MTP transceiver interfaces. These modules facilitate and accelerate IL testing of optical network segments by connecting them to MTP trunks and patch leads.

A loopback test involves sending a signal from a communication device and looping it back to the same device to verify proper functionality or troubleshoot defective network nodes. For fiber optic applications, optical loopbacks validate the operational reliability of devices. Using fiber optic loopback cables or modules for data transmission, the signal emitted by the device is looped from the transmit (Tx) port back to the receive (Rx) port of the same component.

Fiber optic loopback testing is commonly employed for checking fiber optic transceivers. Since transceivers have separate ports for receiving and transmitting light signals, testing these ports is essential to ensure continued operation. The loopback test provides the most convenient method for transceiver maintenance. The testing process routes the laser signal from the transmitter port back to the receiver port, then compares the transmitted pattern with the received pattern to verify they are identical and error-free.
