Description
The AddOn SFP-25GB-CW-31-40-AO is a high-performance, MSA and TAA compliant 25GBase-CWDM SFP28 transceiver designed for seamless integration into modern optical networks. Operating over single-mode fiber (SMF), this transceiver supports data rates up to 25.78 Gbps and delivers reliable transmission distances up to 40 km using a wavelength of 1310nm through an LC connector.
Built with a CWDM DFB laser and APD receiver, the module ensures exceptional signal integrity and low power consumption while supporting dual CDR with a bypass function. It features Digital Optical Monitoring (DOM) for real-time performance metrics and is fully compliant with SFF-8472 and SFF-8402 specifications. Ideal for 25G Ethernet, mobile fronthaul (CPRI/OBSAI), metro, access, and enterprise networks, this transceiver is engineered to deliver high reliability and interoperability. Each unit is uniquely serialized and rigorously tested to meet demanding performance standards and is backed by AddOn’s limited lifetime warranty.
