Cisco Compatible DWDM-SFP-XXXX 1.25G/2.5GBASE-DWDM SFP Optical Transceiver (LC Duplex, C-Band, CH21–CH59, 80km)
Product Overview
The Cisco compatible DWDM-SFP-XXXX optical transceiver is a high-performance 1.25Gbps / 2.5Gbps module designed for Dense Wavelength Division Multiplexing (DWDM) applications over single-mode fiber (SMF). Operating on the ITU-T DWDM C-Band grid, it supports channel options from CH21 to CH59, enabling multiple low-speed services to be transmitted over a single fiber pair with high spectral efficiency.
With a transmission reach of up to 80 kilometers, this SFP module is ideal for telecom access networks, metro aggregation, and enterprise optical transport systems requiring cost-effective DWDM deployment.
“XXXX” represents the DWDM channel (CH21–CH59) or corresponding ITU frequency.
