Wavelength Selection
When the wavelength select (WS) pin is at a logic low or open circuited, the optical wavelength from the CA16
transmitter will be a nominal wavelength as determined by the device code purchased. If the WS pin is pulled high
(logic 1), the optical wavelength will change to the next lower ITU channel number (100 GHz spacing, λ will
increase approximately 0.8 nm).
During the wavelength change, the transmitter’s optical output will be disabled and the wavelength deviation error
alarm will be active until the wavelength has stabilized at its new value. The LSRALM will also be active (logic 1)
during the wavelength change process.
