Cisco DWDM-X2-39.77

The Cisco DWDM-X2-39.77 is a transceiver module used in optical networks. It is specifically designed for Dense Wavelength Division Multiplexing (DWDM) applications. The "X2" form factor refers to the physical size and interface of the module. The DWDM-X2-39.77 operates at a wavelength of 1559.79 nm, which corresponds to a specific channel in the DWDM grid. It supports a data rate of 10 Gbps (Gigabits per second) and is capable of transmitting and receiving optical signals over long distances. This transceiver module is typically used in Cisco networking equipment, such as routers and switches, to enable high-speed and long-distance optical connectivity in DWDM networks.
