1. Product Overview
8 Fibers MPO Fiber Loopback Module is designed to provide a looped signal for testing transmit and receiving functions. It is widely used in testing environments, especially for parallel optics 40G and 100G networks.
This module links Transceivers (TX) and Receivers (RX) positions of MPO transceiver interfaces, facilitating and speeding up IL testing of optical network segments by connecting to MPO trunks or patch leads. It supports verification and testing of MPO interface transceivers, including 40GBASE‑SR4/CSR4 QSFP+ devices.
It is applied for burn‑in and testing of MPO network components and systems, effectively testing transmitter capability and receiver sensitivity of network equipment for telecom and datacom applications. The compact housing ensures high stability, reliability and high‑density deployment.
