Sopto 25G SFP28 fiber optic modules are designed for use in 25GBASE data rate over multimode or single model fiber. They are compliant to IEEE 802.3by, SFF-8472 Rev 12.2 and SFF-8402, and compatible with SFF-8432 and applicable portions of SFF-8431 Rev. 4.1. The fiber optic module is compliant per the RoHS Directive 2011/65/EU.
25G SFP28 module is a 25GBASE interface which has evolved from 100 Gigabit Ethernet, which is typically implemented with 4 × 25 Gbit/s data lanes. Identical in mechanical dimensions to SFP and SFP+, SFP28 implements one 25 Gbit/s lane for top-of-rack switch to server connectivity. SFP28 may also be used to "break out" a single 100GbE port in a top-of-rack switch into four 25 Gbit/s individual server connections. SFP28 supports optical or copper interconnects.
