Overview

100G QSFP28 LR4 LC Optical Transceiver is a high-performance, cost-effective solution designed for 100 Gigabit Ethernet (100GbE) and OTU4 applications over single-mode fiber (SMF). Compliant with IEEE 802.3bm, QSFP28 MSA, and CPRI standards, this transceiver supports data rates up to 103.1 Gbps with a transmission distance of up to 10 kilometers. It integrates four 25Gbps LAN-WDM channels, multiplexed into a single duplex LC connector, operating at wavelengths of 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm.

Featuring low power consumption (<3.5W) and robust thermal performance, it is ideal for data center interconnects, telecom networks, and enterprise backbones. The module supports Digital Diagnostic Monitoring (DDM) for real-time performance tracking and offers superior signal integrity with industry-leading BER (<1E-12). Its compact QSFP28 form factor ensures compatibility with high-density switches and routers, while the LC interface guarantees easy integration with existing fiber infrastructure. Built for reliability, it operates across industrial temperature ranges (-40°C to 85°C), making it suitable for demanding environments.
