The US Transceivers compatible JL485A is a 25GBASE-ESR SFP28 optical transceiver designed for high-speed, short-reach multimode fiber applications. Operating at an 850nm wavelength, this module delivers a data rate of 25.78 Gbps and supports link distances of up to 300 meters over OM4 multimode fiber, making it well suited for dense data center and enterprise environments where reliable, low-latency connectivity is essential.
Built to SFP28 MSA standards, the US Transceivers compatible JL485A is a plug-and-play replacement that supports Digital Diagnostic Monitoring (DDM) for real-time performance visibility. The module is fully compliant with IEEE 802.3by and meets TAA, RoHS, CE, and REACH regulatory requirements, ensuring compatibility with government and enterprise procurement standards.
This transceiver is ideal for server-to-switch interconnects, top-of-rack deployments, storage area networks, and high-performance computing fabrics where 25G multimode connectivity is required over extended short-reach distances.
