Cisco DWDM-X2-55.75

The Cisco DWDM-X2-55.75 is a transceiver module used in optical networking. It is specifically designed for Dense Wavelength Division Multiplexing (DWDM) applications. The "X2" form factor refers to the physical size and interface of the transceiver. The "55.75" in the product name represents 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 data transmission. Each wavelength channel is assigned a specific frequency or wavelength, and the DWDM-X2-55.75 operates on the 55.75th channel. Overall, the Cisco DWDM-X2-55.75 is a transceiver module used for high-speed data transmission over optical networks, specifically in DWDM applications.
