Note: Your Quotation Request will be directed to LasersCom.

The LDS-1590-DFB-2.5G-15/45 from LasersCom is an InGaAsP Multiple Quantum Well Laser Diode that operates from 1587 to 1593 nm. The laser diode delivers an optical output power of up to 15 mW (CW) and 45 mW (peak pulse). It has a DFB cavity with a side mode suppression ratio of above 40 dB and has a spectral linewidth of below 500 kHz. The laser diode is based on LDS technology that provides enhanced thermal stability against optical power with a tracking error of 0.15 dB. It requires a DC supply of 1.7 V and has a current consumption of up to 120 mA of current. The laser diode has an integrated photodiode and is available in a coaxial package with an optical fiber connector. It is ideal for fiber optic communications with data rates of up to 2.5 Gbps.

This laser diode can be ordered for specific configurations from the manufacturer.
