24 Fibers MPO Singlemode Fiber Optic Loopback Module for 40/100G Network Testing

The MPO loopback contains MPO back ring jumping lines in the LOOPBACK configuration, connecting both ends of the fiber into an MPO connector to create a complete light path within the same connector. This enables testing of device launch capacity and receiving sensitivity, particularly in 40/100G network communications. By returning signals, it helps locate various potential issues and facilitates effective testing and evaluation of individual components or interfaces on fiber networks.

Available in multiple configurations, these loopback modules accommodate 8-core, 12-core, and 24-core MPO connectors with various fiber configurations to adapt to different test port requirements.

• 8F MPO Fiber Loopback Module: Verifies and tests transceivers with MPO interface - 40GBASE-SR4/CSR4 QSFP+ devices
• 12F MPO Fiber Loopback Module: Verifies and tests transceivers with MPO interface - 40GBASE-SR4 QSFP+ or 100GBASE-SR4 devices
• 24F MPO Fiber Loopback Module: Verifies and tests transceivers with MPO interface - 100GBASE-SR10 CXP/CFP devices

MPO 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 Transceivers (TX) and Receivers (RX) positions of MPO transceiver interfaces. MPO loopbacks facilitate and accelerate IL testing of optical network segments by connecting them to MPO trunks and patch leads.

OMC offers a comprehensive line of MPO fiber optic loopback assemblies for burn-in and testing of MPO network components and systems. These assemblies effectively test transmitter capability and receiver sensitivity of network equipment, meeting telecom and datacom requirements. They are packaged in compact housing for maximum density in these applications.

A loopback test sends a signal from a communication device and loops it back to the same device to verify proper functionality or troubleshoot defective network nodes. Optical loopbacks verify the operational reliability of devices by routing the signal emitted from the transmit (Tx) end of an active component back to the receive (Rx) end of the same component using fiber optic loopback cables or modules.

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 for maintenance. The testing process routes the laser signal from the transmitter port back to the receiver port, then compares transmitted and received patterns to ensure they are identical and error-free.

• Collocated with 40G or 100G MPO/MPO interface transceivers
• Used for testing transmission capability and receiver sensitivity of fiber optic network equipment
