10-Gigabit Ethernet DWDM Interface Wavelength Overview

For M320, M120, T320, and T640 routers, 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).
