Technical content

The Bookham LambdaFLEX TM iTLA is a high performance continuous wave (CW) tunable laser source for use in the C-band window covering 1528nm to 1563nm. Based on the OIF iTLA standard, the laser and control electronics are pre-mounted on a dedicated circuit board for easy production installation. The iTLA features shuttered tuning, trace tone and SBS dither cir cuitry. Comprehensive control and system reporting is provided over the RS232 interface. The iTLA implements the Bookham DSDBR wideband tunable laser. This laser is a fully monolithic InP chip designed for high volume, low cost manufacturing. With no moving parts, it is a low voltage electr onically tuned device enabling rapid wavelength switching with straightforward control electronics. The integrated semiconductor optical amplifier (SOA) pr ovisions the optical power control and also acts as a shutter to allow dark tuning when reverse biased. Laser chip operation is at a fixed temperature. Wavelength stability is guaranteed by an internal wavelength locker for control to a 50GHz or 100GHz ITU wavelength grid. Fr ont facet output power monitoring is also provided by the wavelength locker for feedback control through the SOA. The device is provided with polarization maintaining fibre for use with an external modulator. Features:

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 Pr otection). However, this applies only for tuning between channels with or without the laser enabled. Enabling the laser fr om a disabled state will take longer ~180ms as the tuning has to be executed mor e 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.

Mechanical Detail (dimensions in mm)

  • 14 way Pin Connector designed to mate with Samtec P/N ASP-113466-019 or equivalent.
  • Module attached with 4 X M2 screws, clearance hole in ITLA, threaded in user housing. The module should be mounted to a flat heat sink or thermal pathway for correct device operation. The module thermal management should ensure that the case temperature does not exceed 75ºC at the worst case end of life dissipation figure of 5.5 Watts.

This allows an external sine wave signal to modulate the laser output power (AM). This input can be used simultaneously with the internal SBS suppression dither function. This input will accept a signal amplitude between 0 and 1Vpp and has a -3dB frequency bandwidth of approximately 3KHz to 2MHz. The transfer function is not controlled so that the user must monitor the resulting AM and adjust the input signal amplitude so as to produce the required modulation depth. This input is inter nally AC coupled. Absolute maximum input is 3Vpp.
