Product Introduction
100G QSFP28 Transceiver Module | Full Series 100GBASE QSFP28 Optical Modules
Product Overview
100G QSFP28 transceiver is mature 100G fiber optic hardware designed for 100G Ethernet leaf-spine data center fabric, 100G OTN transport and HPC high-performance computing interconnection. Each 100G QSFP28 optical module adopts standard 4×25G NRZ four-channel parallel transmission architecture, supporting line rates from 103.125 Gbps to 111.81 Gbps, fully compliant with IEEE 802.3bm and QSFP28 MSA industry specifications.
We supply complete industry standard 100GBASE QSFP28 models including 100GBASE-SR4, 100GBASE-PSM4,
100GBASE-CWDM4, 100GBASE-LR4, 100GBASE-ER4 and ultra-long-reach 100GBASE-ZR4 transceivers, covering transmission distance from 100m up to 80km. This full lineup of 100G QSFP28 fiber transceivers supports MPO-12 and duplex LC optical connectors, compatible with MMF multimode fiber and SMF single-mode fiber, covering short rack-to-rack interconnection, medium campus links, metro aggregation and long-distance backbone transmission scenarios.
All 100G QSFP28 transceivers feature low power consumption below 3.5W, built-in DOM digital optical monitoring and hot-pluggable electrical design without external reference clock. Plug-and-play interoperability with mainstream switches, routers, transmission devices and server clusters makes these standard 100GBASE QSFP28 modules cost-effective universal upgrade hardware for cloud IDC, telecom OTN and supercomputing networks.
