The 25G SFP28 DWDM transceiver is designed for 45955825-Gigabit Ethernet links up to 40km over single-mode fiber. The module consists of DWDM EML Laser, APD, and Preamplifier in a high-integrated optical sub-assembly. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. This module is designed for single-mode fiber and operates at a nominal wavelength of 100GHz ITU Grid, C-Band DWDM wavelength. The module optical connection is duplex LC and shall be compatible with SFP+ 28Gbps and backward compatible with legacy 10G SFP+ pluggable. A 2-wire interface is used for serial ID, digital diagnostics, and module control functions.
