MPO / MTP Fiber Loopback Module | 8/12/24-Core SM & MM Testing Loop
Engineered for precision network diagnostics and equipment burn-in testing. The WolonFiber MPO/MTP Loopback Module provides a reliable return signal path for high-speed parallel optical links, supporting 40G/100G transceiver verification in both single-mode (OS2) and multi-mode (OM3/OM4) configurations.
Description
Product Information
The WolonFiber MPO/MTP Fiber Loopback Module is an essential diagnostic tool for data center engineers and network equipment manufacturers. Designed to route transceiver transmit (TX) signals back to the receive (RX) ports, it allows for accurate testing of optical network capabilities and equipment burn-in processes without requiring an active remote link. Enclosed in a ruggedized, compact casing to protect the internal bare fiber loops from physical damage, these modules ensure consistent insertion loss and high stability. Produced in our manufacturing facility by a rigorous production team of 400 to 500 personnel, every loopback module undergoes strict 3D interferometer testing to guarantee peak performance for 40GBASE-SR4, 100GBASE-SR10, and other parallel optic architectures.
Key Advantages
Precision Diagnostics: Provides an effective and accurate way to test the transmission capability and receiver sensitivity of optical network equipment.
Ruggedized Casing: The protective hard shell shields delicate internal fibers from bending fatigue and environmental contamination.
High-Density Ready: Available in standard 8-core, 12-core, and 24-core configurations to match QSFP+, QSFP28, and CFP transceivers.
Premium Terminations: Utilizes low-loss MPO or authentic US Conec MTP connectors for highly repeatable mating cycles.
Customizable Routing: Internal fiber routing (polarity) can be customized according to specific transceiver mapping requirements.
