FWDM-1629-XX DWDM SFP Preliminary Product Specification – February 2005 F i n i s a r VI. Wavelength Stabilization The laser transmitter will not be turned on until its temperature is adjusted to ensure operation within the specified channel (X +/- 0.4nm). This temperature stabilization time is dependent on the ambient temperature conditions, but will typically occur within 90 seconds of powering the device. The device will transmit within the specified wavelength tolerance (X +/-
