VI. Wavelength Stabilization
The laser transmitter will not be turned on until its temperature is adjusted to ensure
operation within the specified channel (X +/- 300pm). This temperature stabilization time is
dependent on the ambient temperature conditions, but will typically occur within 5 seconds
of powering the device. The module will transmit within the specified wavelength tolerance
(X +/- 100pm) within 10 ms of transmitter operation.
