LambdaFLEXTM iTLA TL5000VLJ Integrable Tunable Laser Assembly with variable output power
Issue 1 January 2007
The Bookham LambdaFLEXTM iTLA is a high performance continuous wave (CW) tunable laser source for use in the L-band window covering 1568nm to 1607nm. The DSDBR laser source and control electronics are populated onto a circuit board assembly and mechanical interface. The iTLA features variable power, shuttered tuning, trace tone and SBS dither circuitry. 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 electronically tuned device enabling rapid wavelength switching via straightforward control electronics. The integrated semiconductor optical amplifier (SOA) provisions the optical power control and also acts as a shutter to allow dark tuning when reverse biased. The laser chip is operated at a fixed temperature, thereby eliminating any slow speed wavelength drift during tuning. Wavelength stability is guaranteed by an internal wavelength locker providing control to a 50GHz or 100GHz ITU wavelength grid. Front facet output power monitoring is also provided by the wavelength locker for feedback control to the SOA. The device is supplied with polarization maintaining fibre for use with an external modulator. Features: * Full Band tunable source L band (1568-1607nm) * High power +10dBm EOL * Variable power range of 6dB * High speed electronic tuning <10ms ch to ch * Electronic shutter for dark tuning * Low power dissipation, 3.8W typical * Excellent SMSR >40dB * Narrow line-width * Low RIN * Wavelength stabilized for 50GHz or 100GHz ITU-T channel spacing * Optical power monitor * SBS Dither / Trace tone capability * Case operating temperature range -5C to +75C * Simple RS232 interface * C band version also available * RoHS compliant * Telcordia Qualified to GR 468 Applications: * Regional metro / Long Haul / Ultra Long Haul * Test and Measurement

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 25C. [5] Specified over product life, operational temperature range and channel optical power budget.

Connector Signal Function
Name DIS SRQ MS TXD RXD RST MFR1 OIF
Note:
This pin can be factory configured to provide an external trace tone input. 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 internally AC coupled. Absolute maximum input is 3Vpp.

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 75C at the worst case end of life dissipation figure of 5.5 Watts.
