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 30 seconds of powering the GBIC (90 seconds maximum). The device will transmit within the specified wavelength tolerance (X +/- 0.1nm) within 5 seconds of transmitter operation. VII.
