8 Fibers MPO OM3 Fiber Optic Loopback Module / Cable
Zion Product Information
Zion Code: ZCM1116HXA1
Zion Description: 8F MPO OM3 Fiber Optic Loopback Module / Cable
The MPO loopback contains MPO back ring jumping lines in the LOOPBACK configuration, with both ends of the fiber terminated 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, various potential phenomena can be identified, allowing effective testing and evaluation of individual components or interfaces within fiber optic networks.
Optical fiber loopbacks are available in multiple configurations, accommodating 8-core, 12-core, and 24-core MPO connectors with various fiber configurations to adapt to different test port requirements. The 8F MPO Fiber Loopback Module verifies and tests transceivers featuring MPO interfaces, specifically 40GBASE-SR4/CSR4 QSFP+ devices.
MPO Loopback modules provide looped signals 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 MPO transceiver interfaces. MPO loopbacks facilitate and accelerate insertion loss (IL) testing of optical network segments when connected to MPO trunks and patch leads.

Fiber Optic Loopback Testing
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 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.
Applications
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. These are optimized for 10/40/100G high-density data center environments.
All OMC MPO Connectors are sourced from Senko/Nissin/Sumitomo. MPO Fiber Patch Cords are high-density cable assemblies used in three primary areas:
- Data Center applications with high-density environments
- Fiber to the building installations
- Internal connector applications within fiber equipment
