Note: Your Quotation Request will be directed to LD-PD Inc.

The PL-LSLD-1550-A-A81-SA from LD-PD Inc is a Superluminescent Diode that has a center wavelength of 1550 nm. It delivers an optical output power of 5 mW and has a spectral bandwidth of 60 nm - 70 nm. This SLD has an internal monitor photodiode (PD) with a maximum dark current of 0.1 μA and a thermoelectric cooler (TEC) that consumes 1.2 A of current.

The PL-LSLD-1550-A-A81-SA has a thermistor resistance of 10 kOhm and an extinction ratio of 20 dB. It requires a forward voltage of 1.8 V and threshold current of 40 mA. This SLD has 0.7 - 1.0 m single mode fiber with FC/APC fiber optic connectors. It is available in a 14-pin standard butterfly package and is ideal for fiber transmission systems, fiber optic gyros, fiber optic sensors, optical coherence tomography, and testing light source applications.
