Cisco Compatible CWDM-SFP-XXXX-40D 1000BASE-CWDM SFP Optical Transceiver (LC Duplex, 1270–1450nm, 40km, DDM)
Product Overview
The Cisco compatible CWDM-SFP-XXXX-D optical transceiver is a high-performance 1Gbps CWDM module designed for long-distance transmission over single-mode fiber (SMF). Supporting wavelengths from 1270nm to 1450nm, it enables multiple Gigabit Ethernet channels over a single fiber pair using Coarse Wavelength Division Multiplexing (CWDM) technology.
With a transmission distance of up to 40 kilometers, this SFP module is ideal for metro access networks, enterprise connectivity, and telecom aggregation. It also supports Digital Diagnostic Monitoring (DDM), allowing real-time monitoring of optical parameters such as temperature, voltage, transmit power, and receive power.
“XXXX” represents the CWDM wavelength option (1270/1290/1310/1330/1350/1370/1390/1410/1430/1450nm).
