SFP56 transceivers are designed for use in single-lane, serial 4-level Pulse Amplitude Modulation (PAM4) 50GBASE-SR, as well as 2-level Amplitude Modulation 25GBASE-SR and 10GBASE-SR Ethernet links, over up to 100m OM4 Multi-Mode Fiber (MMF) for 50GBASE-SR and 25GBASE-SR, and up to 400m for 10GBASE-SR OM4 MMF.
SFP56 transceivers use limiting electrical interface receivers and internal re-timers, while any required Forward Error Correction (FEC) support resides in the host IC. Digital Diagnostics functions are available via a 2-wire serial interface, as per SFF-8472.
The transceivers are compliant with the applicable requirements defined in SFF-8431, SFF-8432, IEEE 802.3cd, IEEE 802.3.bs, and RoHS compliant as described in Application Note AN-2038.
