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