24 Fibers MPO OM4 Fiber Optic Loopback Module / Cable
High-performance MPO OM4 fiber optic loopback module designed for testing and verification of network equipment in 40G/100G data center environments.
Product Identification
Zion Code: ZCM1117HXA1
Zion Description: 8F MPO OM4 Fiber Optic Loopback Module /Cable
Product Overview
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 locate various network phenomena and provide reliable testing and evaluation of individual components or interfaces within fiber optic networks.
Configuration Options
Available in multiple optical fiber circuit configurations to accommodate 8-core, 12-core, and 24-core MPO connectors with various fiber configurations to match specific 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
Testing Applications
MPO Loopback modules provide looped signals to test both transmit and receiving functions. Widely used within testing environments, especially in parallel optics 40G and 100G networks.
Loopbacks are specifically engineered to link Transceivers (TX) and Receivers (RX) positions of MPO transceiver interfaces. They facilitate and accelerate Insertion Loss (IL) testing of optical network segments by connecting 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. Optimized for 10/40/100G high-density data center requirements.
All OMC MPO Connectors are sourced from Senko/Nissin/Sumitomo. MPO Fiber Patch Cables 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
