800G QSFP-DD Loopback Module - High Performance Optical Test Module

This 800G QSFP-DD Loopback Module is a high-performance passive test component designed for QSFP-DD port validation and system debugging in 800G optical communication networks. Compliant with QSFP-DD MSA and IEEE 802.3bs standards, it supports 800Gbps data rate with 8×100G PAM4 modulation, featuring a hot-pluggable standard QSFP-DD form factor for easy deployment. Equipped with MTP/MPO-12 female interface, the passive design requires no power supply, ensuring stable and reliable performance in commercial temperature ranges (0~70℃). Ideal for factory calibration, network equipment port testing and lab R&D validation, it provides a cost-effective solution for verifying 800G optical transceiver and switch port functionality.
