1650nm pulsed DFB laser diode module is wavelength-stabilized

May 27, 2019  Stephen Law

OSI LASER DIODE SCW 1731F-D40R 1650nm AI RWG DFB laser diode module is specially designed for optical test equipment applications where high-peak-pulsed optical power is required. Device’s proprietary design delivers a stabilized wavelength that is unaffected by operational pulse width, making it suitable for OSA/OTDR tasks. Module provides a broader spectrum than is available in traditional DFBs and it exhibits less noise in OTDR and other similar applications. Housed in a 14-pin DIL package, product is RoHS compliant. Device is optically coupled to an SMF fiber pigtail and includes a thermoelectric cooler and an electrically-isolated temperature-sensing thermistor.
