Overview
SFP28 CWDM DFB 25Gb/s SFP28 LR transceiver is designed to transmit
and receive optical data over single mode optical fiber.
The module optical connection is duplex LC and shall be compatible
with 25G SFP28 pluggable and backward compatible with legacy 10G
SFP+ pluggable. The SFP28 LR CWDM module is a dual directional
device with a transmitter and receiver plus a control management
interface (2-wire interface) in the same physical package. 2-wire
interface is used for serial ID, digital diagnostics and module
control function.
The SFP28 LR CWDM module electrical interface is compliant to OFI
CEI-VSR-28G-VSR. It has been designed to meet the harshest external
operating conditions including temperature, humidity and EMI
interference.
