Product Overview:

LDS-1310-FP-1.25G-15/80 is an InGaAsP MQW laser diode with internal photodiode, coupled to an optical fiber and packaged into a hermetic TO-case. This compact coaxial laser is mounted in a double-sided bracket to facilitate mounting and heat-sinking. The special feature of the LDS technology is the increased thermal stability of optical power.

    • Wavelength: 1310 nm
    • Cavity type: Fabry-Perot
    • Data rate up to 1.25 Gbps
    • Optical power: up to 15 mW in CW mode and up to 80 mW in pulse mode in the single-mode fiber G.657.A1
    • Typical thermal stability of optical power (tracking error) 0.15 dB
    • Package types: coaxial
    • Built-in monitor photodiode

Important Notes on Operating Laser Diodes:

Electrical Operation: Operating a laser diode above the maximum ratings shown on the data sheet even for very short periods of time can damage the laser diode or reduce its lifetime. They should be electrically biased with a "laser diode driver" class current supply with low electrical noise and protection against voltage and current surges. Laser diodes are very sensitive to electrostatic discharge (ESD). Proper ESD precautions must be taken.

Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diode‘s package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
