The CWDM-SFP-1450-40-C is a Cisco-compatible 1000Base-CWDM SFP transceiver operating at 1450 nm, designed for Gigabit Ethernet links up to 40 km over single-mode fiber.
This SFP is fully compatible with Cisco switches, routers, and firewalls that feature Gigabit Ethernet SFP ports and support Cisco-unlocked optics.
The module requires ITU-T G.652 single-mode fiber (SMF) with standard LC/UPC connectors for optimal 40 km transmission performance.
The CWDM-SFP-1450-40-C supports a maximum link distance of 40 km when used with standard single-mode fiber.
It operates at a central wavelength of 1450 nm, conforming to CWDM channel spacing for dense wavelength multiplexing.
Yes, this SFP module is fully hot-swappable, allowing insertion or removal without powering down the host device.
Yes, it includes SFF-8472 Digital Optical Monitoring for real-time metrics like optical power, temperature, and voltage.
The transceiver supports a data rate of 1.25 Gbps for Gigabit Ethernet, ensuring reliable full-duplex communication.
It operates in a commercial temperature range from 0 °C to 70 °C, suitable for standard data center and campus environments.
Simply insert the module into an empty SFP slot until it clicks, then configure the interface with standard Cisco IOS commands for 1000Base-CWDM.
Yes, its 1450 nm wavelength is CWDM-compliant, allowing seamless integration with 8-channel or 16-channel CWDM multiplexers and demultiplexers.
It provides a typical optical power budget of 9 dB, sufficient for reliable 40 km fiber links under IEEE 802.3ah specifications.
No additional firmware is required; it functions out-of-the-box with Cisco IOS and compatible network operating systems.
The CWDM-SFP-1450-40-C comes with a one-year limited warranty and free technical support for configuration, troubleshooting, and compatibility.
