The 100Gbps QSFP28 ZR4 Optical Transceiver is designed for ultra-long-distance communication over single-mode fiber (SMF) up to 80 kilometers. Supporting data rates of 103.125Gbps, this module operates with a 4-channel LAN WDM architecture, multiplexing and demultiplexing four lanes of 25Gbps signals. It features cooled EML lasers for precise wavelength alignment and SOA+PIN photodetectors for enhanced signal reception. Fully compliant with QSFP28 MSA, IEEE 802.3ba standards, and ITU-T G.959.1, it is ideal for applications in 100G Ethernet and telecom networks.
Operating on a single +3.3V power supply with a maximum power consumption of 6.5W, the transceiver is energy-efficient and reliable across a temperature range of 0°C to 70°C. It features a hot-pluggable QSFP28 form factor with an LC duplex connector for seamless integration. Advanced digital diagnostic monitoring supports real-time tracking of key performance metrics like temperature, voltage, optical power, and bias current. With RoHS compliance and robust safety features, this transceiver is a dependable solution for high-speed, long-distance optical communication in data centers and metro networks.
The CT-QSFP28-ZR4 is a QSFP28 form-factor optical transceiver designed for 100GBASE-ZR4 Ethernet over long-distance single-mode fiber. It integrates four 25.78125 Gb/s electrical lanes, multiplexed into four LAN-WDM optical channels (1295–1310 nm). The module supports up to 80 km transmission on G.652 SMF with FEC, uses a duplex LC connector, and operates from a single +3.3 V power supply with maximum power consumption of 6.5 W. Built-in DDM/DOM provides monitoring of optical power, temperature, voltage, and bias current.
