Cisco DWDM-XFP-51.72

The Cisco DWDM-XFP-51.72 is a transceiver module used in optical communication networks. It is specifically designed for Dense Wavelength Division Multiplexing (DWDM) applications. 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 "51.72" in the name refers to the specific wavelength of light that the transceiver operates on. In this case, it operates on a wavelength of 5172 nm, which is within the DWDM wavelength range. Overall, the Cisco DWDM-XFP-51.72 is a transceiver module that enables high-speed data transmission over optical fibers in DWDM networks.
