Cisco DWDM-XFP-55.75

The Cisco DWDM-XFP-55.75 is a specific type of transceiver module used in optical networking. It is designed to support Dense Wavelength Division Multiplexing (DWDM) technology, which allows multiple wavelengths of light to be transmitted simultaneously over a single optical fiber. The "XFP" in the name refers to the form factor of the transceiver, which is a small, hot-pluggable module commonly used in high-speed data communication applications. The "55.75" indicates the specific wavelength at which the transceiver operates, measured in nanometers. Overall, the Cisco DWDM-XFP-55.75 is a transceiver module that enables high-speed data transmission over long distances using DWDM technology.
