Cisco DWDM-SFP10G-39.77

The Cisco DWDM-SFP10G-39.77 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 using DWDM technology. The "39.77" in the product name refers to the specific wavelength channel that this transceiver operates on. DWDM technology allows multiple wavelengths of light to be transmitted simultaneously over a single optical fiber, enabling high-capacity data transmission. The Cisco DWDM-SFP10G-39.77 is capable of transmitting and receiving data at a rate of 10 gigabits per second (10Gbps) and supports a transmission distance of up to 80 kilometers (49.7 miles) depending on the optical network infrastructure. This transceiver module is typically used in Cisco networking equipment, such as routers and switches, to enable high-speed and long-distance data communication in enterprise and service provider networks.
