Overview
The Cisco CWDM-SFP10G-1490 is a transceiver module designed to transmit 10 Gigabit Ethernet data over long distances using single-mode fiber. It achieves this by utilizing Coarse Wavelength Division Multiplexing (CWDM) technology and a specific wavelength of 1490 nanometers. This allows the transceiver to transmit data up to 80 kilometers without needing extra amplifiers. The CWDM-SFP10G-1490 is compatible with Cisco SFP+ ports and adheres to industry standards for size and functionality. It also offers real-time performance monitoring through a built-in interface. While not directly manufactured by Cisco, there are many compatible third-party options available. It's important to remember that CWDM transceivers need to be used in pairs with matching wavelengths to avoid signal interference. Overall, the CWDM-SFP10G-1490 provides a cost-effective solution for extending your 10 Gigabit Ethernet network over long distances on single-mode fiber.
