Description
The AddOn Cisco® SFP-25G-LR-CW-51-AO is a high-performance 25GBase-CWDM SFP28 transceiver designed to deliver reliable, high-speed data transmission up to 10km over single-mode fiber (SMF) using a 1510nm wavelength via a duplex LC connector. Fully compatible with Cisco® switches and routers, this hot-swappable transceiver ensures seamless integration into existing network infrastructures.
It features a CWDM-rated EML transmitter and APD receiver, built-in dual CDR with bypass, and supports Digital Optical Monitoring (DOM) for real-time diagnostics. Ideal for 25G Ethernet, access, metro, enterprise, and mobile fronthaul applications, this module is TAA-compliant, RoHS-certified, and engineered for maximum reliability and performance. Each unit is uniquely serialized and rigorously tested to meet MSA, SFF-8431, and IEEE 802.3 standards, backed by AddOn’s limited lifetime warranty.
