Technical content

Specifically designed for use as a low speed out of band optical service channel for optical amplifiers. The laser is available in a low-inductance 14-pin butterfly package with single-mode connectorized fiber-optic pigtail with a rated peak output power of 2 mW. At 1510 nm, the LC151B-20 does not interfere with WDM traffic and operates outside the normal EDFA gain region. The high reliability buried hetero-structure DFB laser chip ensures the reliability of the LC151B-20 over the entire range of recommended operating conditions. Features:

  • Wavelength 1510 nm
  • Designed to operate at 4 Mb/s - 155 Mb/s
  • Low threshold, high reliability BHet laser chip
  • Hermetically sealed 14 pin high speed butterfly package
  • High output power 2 mW minimum CW
  • Internal InGaAs monitor photodiode
  • Available with several optical connector options
  • RoHS compliant Applications:
  • Optical Service Channel (OSC) applications in DWDM transmission systems using optical amplifiers. 4 - 155 Mb/s Single-Mode OSC Laser, 1510 nm LC151B

Tolerances ± 0.25 mm Finish: Gold plate Pin 1 and Pin 2 Thermistor The thermistor is used in a control loop in conjunction with the thermo-electric cooler to maintain the laser submount temperature at the required value. Operating current should be less than 100 µA to prevent selfheating errors. Pin 3 Laser modulation (-) and bias The data input (modulation) and bias are both applied via this pin which has a nominal 25 Ohm load impedance. Pin 4 Monitor anode, Pin 5 Monitor cathode The back facet monitor diode provides a mean power reference for the laser and is nor mally operated with a 5 V reverse bias. Pin 6 TEC (+), Pin 7 TEC (-) Applying a positive voltage on pin 6 with respect to pin 7 will cause the internal submount to be cooled relative to the case temperature. Reversing the polarity will raise the submount temperature relative to the case. Care should be taken to avoid overheating the submount when driving the TEC in this manner. The TEC supply should be capable of delivering up to 1.2 A at 2.5 V. Pin 8, 9, 11, 13 Case gr ound. These pins must be grounded in all applications. Pin 10, 14 N/C These pins are not connected. They should be grounded if possible. Pin 12 Laser (+) This pin provides the return path for the laser modulation and bias circuits.
