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

High-performance MPO OM3 fiber optic loopback module designed for testing and verification of network equipment in 40G/100G data center environments.

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 comprehensive testing of device launch capacity and receiving sensitivity, particularly in 40/100G network communications. By returning signals to the source, these loopbacks effectively identify and locate various network phenomena for thorough testing and evaluation of fiber network components and interfaces.

Available in multiple optical fiber configurations to accommodate 8-core, 12-core, and 24-core MPO connectors, adapting to various test port requirements:

MPO Loopback modules provide looped signals to test transmit and receiving functions, widely used within testing environments especially for parallel optics 40G and 100G networks. These loopbacks are engineered to link Transceivers (TX) and Receivers (RX) positions of MPO transceiver interfaces. They facilitate and accelerate IL testing of optical network segments by connecting to MPO trunks and patch leads.

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

12F MPO-LC/SC/FC/ST Straight harness Cables are designed for 40G LR4 PSM, 40GBASE-SR4, 40G QSFP+ PLR4 and high-density data center applications. Optimized for 10/40/100G high-density data center environments, these assemblies utilize MPO Connectors from Senko/Nissin/Sumitomo and serve three primary application areas:

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

For transceiver modules not specifically mentioned, suitable loopback selection can be determined by analyzing interface type, physical contact requirements, and cable type specifications.

These fiber optic cables are packaged in easily handled, well-protected packaging labeled and marked by OMC as standard. Available carton sizes: 34*22*15 cm; 44*34*24 cm; 54*39*34 cm. Carton selection depends on order quantity. Custom packaging options available.
