1. Product Overview: Bookham iTLA (Integrable Tunable Laser Assembly)

️· Purpose: A module designed for optical communication systems, specifically for tuning a laser and providing stable output. It complies with OIF (Optical Internetworking Forum) standards.
️· Functionality: Tunable laser, enables SBS suppression or Trace Tone functionality (but not both simultaneously without external frequency source). It is possible to modulate laser output power (AM) using the MFR1 input.
️· Applications: SONET/SDH protection (OIF "Application A").

2. Technical Specifications:

️· Frequency vs. Power Mask: Meets a specific frequency/power mask during power-up, disable, and channel changes.
️· Electrical Characteristics:
- Supply Voltages: +3V3 (3.15V - 3.45V), -5.2V (-5.45V - -4.94V).
- Power Dissipation: Up to 5.5 Watts.
- RS232 Interface: 9600 - 115200 baud.
️· Environmental:
- Storage Temperature: -40°C to +85°C.
- Operating Temperature: -5°C to +75°C.
️· Optical Fibre:
- Length: 1400mm +/- 100mm.
- Connector: FC-UPC.
- Polarization maintaining PANDA fibre.

3. Pinout and Connections:

️· Key Pins:
- `DIS`: Disable laser.
- `SRQ`: Service Request.
- `MS`: Module I/O reset.
- `TXD/RXD`: RS232 Transmit/Receive.
- `RST`: Reset (laser off).
- `MFR1`: Manufacturer connection – can be configured to accept an external trace tone input (AM modulation). Input signal between 0 and 1Vpp, AC-coupled, max input 3Vpp.
- `OIF`: Reserved for future use.

4. Key Features & Considerations

️· Trace Tone/AM Modulation (MFR1): Can be used for modulating laser power (AM). Requires an external signal.
️· Warm-up Time: Initialisation time ~60 seconds.
️· Module Mounting: Attached with screws. Requires a flat heat sink for heat dissipation (max case temperature 75°C).
️· RoHS Compliant: Meets environmental standards for restricted hazardous substances.
️· Evaluation Kit: Available for testing and characterization.

5. Ordering Information:

️· Part Number: TL5000DCJ (includes FC/UPC connector).
