12 Fibers MPO OM3 Fiber Optic Loopback Module for 40/100G Network Testing

The MPO loopback contains MPO fiber jumpers in a loopback configuration, connecting both ends of the fiber into a single MPO connector to create a continuous 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 enables effective testing and evaluation of individual components or interfaces on fiber networks.

Available in multiple optical fiber circuit configurations to accommodate 8-core, 12-core, and 24-core MPO connectors with various fiber configurations for comprehensive port testing.

MPO Loopback modules provide looped signals to test transmit and receiving functions. They are widely used in testing environments, especially within parallel optics 40G and 100G networks. Loopbacks are designed to link Transceiver (TX) and Receiver (RX) positions of MPO transceiver interfaces. MPO loopbacks facilitate and accelerate insertion loss (IL) testing of optical network segments by connecting them to MPO 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 loopback testing, optical loopbacks verify the operational reliability of devices. Using fiber optic loopback cables or modules, the signal emitted by the device is looped from the transmit (Tx) end back to the receive (Rx) end of the same component.

12F MPO-LC/SC/FC/ST straight harness cables are designed for 40G LR4 PSM, 40GBASE-SR4, 40G QSFP+ PLR4 and high-density data centers. Optimized for 10/40/100G high-density data center applications.

All OMC MPO Connectors are sourced from Senko/Nissin/Sumitomo. MPO Fiber Patch Cords are high-density cable assemblies used in three primary areas:

When selecting a loopback for a transceiver, consider connector type, polish type, and cable type. The following tables provide selection guidance for commonly used transceiver modules.

This guide covers specific fiber loopback choices for commonly used fiber optic transceivers. For other transceiver modules not mentioned, suitable loopbacks can be selected by understanding interface type, physical contact, and cable type requirements.
