Configuring the 10-Gigabit Ethernet DWDM Interface Wavelength

For M320, T320, and T640 routing platforms, the 10-Gigabit Ethernet DWDM PIC enables you to configure 10-Gigabit Ethernet 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). To configure the wavelength on a 10-Gigabit Ethernet DWDM interface, include the wavelength statement at the [edit interfaces ge-fpc/pic/port optics-options] hierarchy level:

[edit interfaces ge-0/0/0 optics-options]

wavelength nm;

For interface diagnostics, you can issue the show interfaces diagnostics optics ge-fpc/pic/port operational mode command.

Table 38 shows configurable wavelengths and the corresponding frequency for each configurable wavelength.
