OSI Laser Diode introduces the SCW 1632-350R, a high-power, pulsed laser diode module for optical testing applications. Housed in a 14-pin butterfly package, the new ridge waveguide (RWG) Fabry-Perot (FP) laser diode is optically coupled to a single-mode fiber (SMF) pigtail and includes a thermoelectric cooler (TEC) and an electrically-isolated temperature-sensing thermistor. Ideal for applications where high peak pulsed optical power is required, the new device is specifically designed for use in optical spectrum analyzers (OSAs) and optical time domain reflectometers (OTDRs). The higher power gives the OTDR manufacturer greater dynamic range capability. OSI Laser Diode’s SCW 1632-350R operates at 1625 nm and features optical power of 350 mW (typically). It joins the family of high-power pulsed laser diode modules, including the previously introduced SCW 1532-500R that operates at 1550 nm and features higher than 500 mW optical power. Both modules are RoHS compliant and feature the industry-standard pin-out packaging that offers excellent pulse drift performance and high stability.
