Cisco DWDM-X2-58.98

The Cisco DWDM-X2-58.98 is a specific type of transceiver module used in optical networking. It is designed to support Dense Wavelength Division Multiplexing (DWDM) technology, which allows multiple wavelengths of light to be transmitted simultaneously over a single optical fiber. The "X2" in the product name refers to the form factor of the transceiver module, which is a hot-swappable, small form-factor pluggable (SFP) module. The "58.98" indicates the specific wavelength of light that the module is designed to transmit and receive, in this case, 1558.98 nanometers. Overall, the Cisco DWDM-X2-58.98 is used in optical networking applications to enable high-speed data transmission over long distances by leveraging DWDM technology.
