Description
The AddOn Cisco® CWDM-SFP25G-1270-40 Compatible TAA 25GBase-CWDM SFP28 Transceiver delivers reliable, high-speed data transmission for enterprise, metro, and mobile fronthaul networks. Designed for seamless compatibility with Cisco® equipment, this SFP28 module supports data rates up to 25.78 Gbps and transmits over single-mode fiber (SMF) for distances up to 40 km using a 1270nm CWDM DFB laser.
Engineered with a hot-pluggable SFP28 footprint, dual CDR with bypass, and digital optical monitoring (DOM), this transceiver ensures simplified deployment, robust performance, and real-time link diagnostics. It is RoHS compliant, lead-free, and TAA compliant, making it ideal for government, enterprise, and carrier-grade network applications. Each unit is programmed, serialized, and rigorously tested for guaranteed interoperability and OEM-equivalent performance.
