Cisco DWDM-SFP10G-50.12

The Cisco DWDM-SFP10G-50.12 is a Cisco Dense Wavelength-Division Multiplexing (DWDM) Small Form-Factor Pluggable (SFP) transceiver module. It is designed to provide high-speed data connectivity over long distances in optical networks. The "DWDM" in the name stands for Dense Wavelength-Division Multiplexing, which is a technology that allows multiple optical signals to be transmitted simultaneously over a single optical fiber by using different wavelengths of light. This enables the efficient utilization of the available fiber capacity. The "SFP10G" indicates that it is a 10 Gigabit Ethernet SFP transceiver, capable of transmitting data at a rate of 10 Gbps. The "50.12" refers to the specific wavelength of light that this transceiver operates on. In this case, it operates on a wavelength of 1550.12 nm. Overall, the Cisco DWDM-SFP10G-50.12 is a transceiver module that enables high-speed data transmission over long distances using DWDM technology.
