Description
The AddOn SFP-25GBDW44-10-I-AO is an MSA and TAA compliant 25GBase-DWDM SFP28 transceiver designed for high-performance, long-distance networking applications. Operating at a wavelength of 1542.14nm with 100GHz channel spacing, it supports up to 10km transmission over single-mode fiber (SMF) via a duplex LC connector.
Engineered for industrial temperature ranges (-40°C to 85°C), this hot-pluggable transceiver is fully compliant with SFF-8432 and SFF-8472 standards, offering digital optical monitoring (DOM) for real-time performance visibility. Built with excellent ESD protection, a low-EMI metal housing, and rigorous AddOn testing, it ensures seamless integration and reliable performance across enterprise, metro, and access networks.
Protected by AddOn’s limited lifetime warranty, this module delivers cost-effective, OEM-equivalent optical networking with uncompromised quality.
