Product Overview:

1310nm DFB Laser, Single Mode / Single Frequency, 24.5mW

Eblana's DFB laser is built using discrete-mode (DM) technology, delivering a cost-effective laser diode with mode-hop free tuneability, excellent SMSR, and narrow linewidth.

Eblana's 1310nm ADF series laser is a high performance single wavelength source, available in a 14-pin butterfly package with PM fibre pigtail. The frequency response and linearity of this laser makes it an excellent choice for CATV systems, GSM/CDMA repeater, and optical sensing.

Each laser module is supplied with a full set of characterization data.

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.
