Description
The AddOn SFP-25GB-CW-51-10-EX-AO is a 25GBase-CWDM SFP28 optical transceiver designed for high-performance data transmission over single-mode fiber (SMF) at distances up to 10km using a 1510 nm wavelength. Engineered for seamless interoperability, it is 100% compatible with Extreme Networks® equipment and meets all SFP28 MSA, SFF-8431/8432, and SFF-8472 standards.
Equipped with a CWDM-rated EML transmitter, APD receiver, and dual CDR with bypass, this module delivers bi-directional data rates up to 25.78 Gbps with low power consumption and reliable performance in demanding environments. It also supports Digital Optical Monitoring (DOM), providing real-time insight into key operating parameters for proactive network management.
Ideal for enterprise, metro, access, and mobile fronthaul applications, this hot-swappable, TAA-compliant transceiver is rigorously tested for quality, serialization, and full functionality — backed by AddOn’s limited lifetime warranty for long-term network reliability.
