Sophos ASG0000SR Compatible 10GBASE-SR SFP+ Transceiver Module (MMF, 850nm, 300m, LC, DOM)
This Sophos ASG0000SR compatible SFP+ transceiver supports 10GBase-SR throughput up to 300m over multimode fiber (OM3 MMF) and 400m over OM4 MMF. It complies with SFP+ MSA, SFF-8431, SFF-8432, and IEEE 802.3ae standards, ensuring seamless interoperability within a multi-vendor network. This module is ideal for 10G connectivity environments, such as SOHO networks, data centers, enterprise wiring closets, large campuses, Metro Area Networks, Remote Radio (RRU), and Baseband Units (BBU). Most importantly, we code and test each SFP+ module to ensure it works with the Sophos 10G network switches, routers, servers, and network interface cards (NICs).
