8 Fibers MPO OM4 Fiber Optic Loopback Module / Cable
The 8F MPO OM4 Fiber Optic Loopback Module/Cable is designed for testing and verification of network equipment in high-speed data communication environments.
Product Identification
Zion Code: ZCM1117HXA1
Zion Description: 8F MPO OM4 Fiber Optic Loopback Module /Cable
The MPO loopback contains MPO connectors that loop both ends of the fiber within the same connector, creating a closed optical path. This enables testing of device launch capacity and receiving sensitivity, particularly in 40/100G network communications. By returning signals to the source, it helps locate various network phenomena and facilitates effective testing and evaluation of individual components or interfaces within fiber optic networks.
Configuration Options
Optical fiber loopbacks are available in multiple configurations to accommodate 8-core, 12-core, and 24-core MPO connectors with various fiber configurations to match 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 - 40GBASESR4 QSFP+ or 100GBASE-SR4 devices
- 24F MPO Fiber Loopback Module: Verifies and tests transceivers with MPO interface - 100GBASESR10 CXP/CFP devices
Testing Applications
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 connect Transceivers (TX) and Receivers (RX) positions of MPO transceiver interfaces, facilitating and speeding up 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. Optical loopbacks verify the operational reliability of devices by looping the signal emitted from the transmit (Tx) end 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. 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 in fiber equipment
