Description

The 25G SFP28 CWDM 40KM optical transceiver is a high-performance module designed for long-reach, cost-effective optical transmission over single-mode fiber. Supporting CWDM wavelengths from 1270nm to 1370nm (DML) or 1470nm to 1570nm (EML), it enables multiple 25Gbps channels for high-density deployments while maximizing fiber utilization.

With a transmission distance of up to 40 kilometers, this transceiver is ideal for 5G fronthaul, data center interconnects, and enterprise backbone networks. Its DFB laser and high-sensitivity APD receiver provide reliable signal performance across long distances, ensuring low-latency, high-bandwidth connectivity in demanding network environments.

Designed in a hot-pluggable SFP28 form factor with a duplex LC interface, the module integrates seamlessly with standard 25G network equipment. Digital diagnostic monitoring (DDM) allows real-time tracking of key parameters such as temperature, voltage, and optical power. Its all-metal housing ensures superior EMI protection, and it supports wide temperature ranges for commercial and extended deployments.
