Description
The AddOn SFP-25GB-CW-27-40-AO is a high-performance, MSA-compliant 25GBase-CWDM SFP28 transceiver designed for up to 40km transmission over single-mode fiber (SMF) using a 1270nm CWDM wavelength. Engineered with a CWDM DFB laser and APD receiver, this hot-pluggable module delivers reliable and efficient 25.78Gbps data links for demanding network environments.
Ideal for 25G Ethernet, access, metro, and enterprise networks as well as mobile fronthaul CPRI/OBSAI deployments, this transceiver supports Digital Optical Monitoring (DOM) for real-time diagnostics and is TAA and RoHS compliant. Built with a durable metal enclosure to minimize EMI and featuring dual CDR with bypass functionality, it seamlessly integrates into existing infrastructures while maintaining exceptional signal integrity and low power consumption.
