Overview

100G QSFP28 ZR4 LC Optical Transceiver is a cutting-edge solution designed for ultra-long-haul 100 Gigabit Ethernet (100GbE) and OTU4 applications, achieving transmission distances of up to 80 kilometers over single-mode fiber (SMF). Compliant with IEEE 802.3ct, QSFP28 MSA, and OIF standards, this transceiver leverages advanced coherent optics and four 25Gbps LAN-WDM channels, multiplexed into a duplex LC interface, to deliver data rates up to 103.1 Gbps. It operates at wavelengths of 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm, ensuring high signal fidelity and minimal dispersion.

Ideal for metro/core networks, hyperscale data center interconnects, and carrier-grade infrastructures, the module integrates forward error correction (FEC) and high-sensitivity receivers to maintain ultra-low bit-error rates (BER <1E-12) over extreme distances. With a power consumption of <5W and robust thermal design, it supports industrial temperature ranges (-40°C to 85°C) for harsh environments. Digital Diagnostic Monitoring (DDM) enables real-time performance tracking, while its compact QSFP28 form factor ensures compatibility with high-density systems. The LC connector simplifies integration into existing fiber networks, making it a reliable, future-proof choice for scalable long-reach connectivity.
