Note:

[1] The Bookham iTLA incorporates a single onboard oscillator which is used to provide either SBS suppression or Trace Tone functionality, but cannot provide both functions

simultaneously. However the iTLA MFR1 input can be used to enable an external frequency source to be applied enabling both SBS suppression and Trace Tone functionality.

[2] The Bookham laser is guaranteed to tune within 10ms which is to comply with the OIF "Application A" (SONET/SDH Protection). However, this applies only for tuning

between channels with or without the laser enabled. Enabling the laser from a disabled state will take longer ~180ms as the tuning has to be executed more slowly in order to

maintain frequency accuracy and comply with the power/frequency mask.

[3] Time required from application of Vcc and Vee supplies for the iTLA to reach an operational state . Complies with the OIF MSA module warm up time.

[4] This is defined as the Start of Life (SOL) power adjustment range, specified at an iTLA case temperature of 25ºC.

[5] Specified over product life, operational temperature range and channel optical power budget.
