Product Introduction
200G QSFP56 Transceiver Module | 200G PAM4 QSFP56 Optical Module
|SR4/DR4/FR4/LR4/ER4
Product Overview
Our 200G QSFP56 transceiver module is a high-performance 200G PAM4 optical module designed for modern 200GE leaf-spine data center interconnection, widely recognized as the mainstream high-speed fiber optic solution for cloud computing, AI GPU clusters, HPC and 5G mobile backhaul networks. This full series 200G QSFP56 optical transceiver adopts a standard 4×50Gbps PAM4 modulation architecture with a total bandwidth of 212.5Gbps, fully compliant with IEEE 802.3bs/cd and QSFP56 MSA industry standards. We supply complete standard 200G QSFP56 models including SR4, DR4, FR4, LR4 and long-reach ER4 40km transceivers, covering transmission distances from 100m to 40km to meet short-range rack-to-rack, medium campus interconnection and long-distance metro backbone transmission demands.
Each 200G QSFP56 fiber optic module supports digital DOM diagnostic monitoring, hot-pluggable QSFP56 form factor, and delivers stable low-BER transmission performance on both multimode MMF and single-mode SMF fiber cables. All 200GE QSFP56 transceivers are fully compatible with major brand network switches, servers and storage devices, making them the cost-effective upgrade choice for high-density data center fabric.
