Cisco DWDM-XFP-50.12

The Cisco DWDM-XFP-50.12 is a specific type of transceiver module used in optical networking. It is part of Cisco's Dense Wavelength Division Multiplexing (DWDM) product line. The "XFP" in the name stands for 10 Gigabit Small Form Factor Pluggable, which is a standard for transceiver modules used in high-speed data communication networks. The "50.12" in the name refers to the specific wavelength channel that this transceiver operates on. In DWDM systems, multiple wavelengths of light are transmitted simultaneously over a single optical fiber, allowing for increased capacity and efficiency. Each wavelength channel is assigned a specific frequency or wavelength, and the DWDM-XFP-50.12 operates on the 50th channel at a wavelength of 1550.12 nm. Overall, the Cisco DWDM-XFP-50.12 is a transceiver module designed for high-speed data transmission over optical networks using DWDM technology.
