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.
