25G SFP28 Fiber Optic Module

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.
