The change from one frequency to another takes about 10 seconds. Do not expect traffic to transit the
system until the frequency selection completes. Also, successive laser frequency commands are ignored
until after the new channel frequency stabilizes.
Note This interface command is applicable only to tunable lasers that support transmission over multiple
frequencies on the ITU grid. The values displayed for selection vary depending on the capabilities of the
line card.
