Dense Wavelength Division Multiplexing (DWDM) Interface Wavelength

 

Use this topic to understand about the dense wavelength-division multiplexing (dwdm) wavelength parameter and how to configure the wavelength for 10-Gigabit and 100-Gigabit Ethernet Interfaces.

Ethernet DWDM Interface Wavelength Overview

Dense wavelength-division multiplexing (DWDM) interfaces are supported on 10-Gigabit Ethernet DWDM PICs, MICs, and MPCs; the 10-Gigabit Ethernet LAN/WAN OTN PIC; and the 100-Gigabit Ethernet DWDM OTN PIC. When a tunable optic transceiver is available, you can configure the DWDM interfaces with full C-band International Telecommunication Union (ITU)-Grid tunable optics, as defined in the following specifications:

  • Intel TXN13600 Optical Transceiver I2C Interface and Customer EEPROM Preliminary Specification, July 2004.

  • I2C Reference Document for 300-Pin MSA 10G and 40G Transponder, Edition 4, August 04, 2003.

By default, the wavelength is 1550.12 nanometers (nm), which corresponds to 193.40 terahertz (THz).

Configuring the 10-Gigabit or 100-Gigabit Ethernet DWDM Interface Wavelength

To configure the wavelength on 10-Gigabit Ethernet or 100-Gigabit Ethernet dense wavelength-division multiplexing (DWDM) and OTN interfaces, include the wavelength statement at the [edit interfaces interface-name optics-options] hierarchy level:

To display the currently tuned wavelength and frequency for the interface, use the show interfaces interface-name operational mode command.

For interface diagnostics, issue the show interfaces diagnostics optics interface-name operational mode command.

Table 1 shows configurable wavelengths and the corresponding frequency for each configurable wavelength.
