Cisco DWDM-XFP-48.51

The Cisco DWDM-XFP-48.51 is a specific type of transceiver module manufactured by Cisco Systems. It is part of the Cisco Dense Wavelength-Division Multiplexing (DWDM) XFP series. This transceiver module is designed for use in high-speed optical networks and supports data rates of up to 10 Gbps. It utilizes the XFP form factor, which is a hot-swappable, small form-factor pluggable module commonly used in networking equipment. The "48.51" in the product name refers to the specific wavelength of light that this module operates on. In DWDM systems, different wavelengths of light are used to transmit multiple data signals simultaneously over a single optical fiber. Each wavelength is assigned a specific channel number, and the DWDM-XFP-48.51 operates on channel 48.51. Overall, the Cisco DWDM-XFP-48.51 is a transceiver module used for high-speed data transmission in optical networks, specifically operating on a specific wavelength channel in a DWDM system.
