Cisco CWDM-SFP-1490-40 Compatible SFP Module - 1000BASE-CWDM 40km Single Mode 1490nm LC Transceiver
Couldn't load pickup availability
This high-performance 1000BASE-CWDM SFP transceiver is engineered for wavelength division multiplexing applications, delivering reliable connectivity up to 40 kilometers over single-mode fiber. Operating on the 1490nm CWDM channel, this module enables multiple data streams to be transmitted simultaneously over a single fiber pair, maximizing fiber infrastructure utilization and reducing deployment costs.
The module features full DDM (Digital Diagnostics Monitoring) support, enabling real-time monitoring of transceiver status including optical power levels, temperature, and voltage through most SNMP network management tools. This allows for proactive network maintenance and simplified troubleshooting across your CWDM network.
Fully compatible with Cisco switches and MSA (uncoded) standards, this transceiver serves as a direct replacement for Cisco's CWDM-SFP-1490-40 module, offering exceptional value without compromising performance or reliability.
Important Note: CWDM transceivers use specific wavelength channels (1270nm to 1610nm in 20nm increments). This 1490nm module can be combined with other CWDM wavelengths on the same fiber pair to create multi-channel CWDM systems. Ensure wavelength compatibility when designing your CWDM network.
