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).
