OM6253ZX210 is a tunable transceiver module designed for 80 km optical communication applications, and it is compliant to SFP+ MSA standard. This module can convert a 10 Gbps electrical data to 10 Gbps optical signals. They are compliant with SFP+ MSA, SFF-8431 and SFF-8472, and are mainly used in Telecom, Wireless, InfiniBand, and Fiber Channel. The transceiver is RoHS compliant. Smartoptics multiprotocol SFP+ transceivers support Fibre Channel speeds up to 16G and 10G Ethernet for storage, enterprise and mobile networks. SFP+ transceivers are focused on SAN protocols ranging from 1G up to 16G while also supporting other protocols such as Ethernet.
[pdf] SFP ports are modular network interfaces used to connect switches, routers, servers, and fiber optic links through interchangeable transceiver modules. Unlike standard RJ45 Ethernet ports, SFP ports can support both fiber optic and copper Ethernet connections depending on the installed module. Think of it as the “translator” for your network equipment, converting electrical signals into optical signals. Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. Transceiver compatibility is a key concern in enterprise network deployments.
