OSI Laser Diode Launches Wavelength-Stabilized 1650 nm Pulsed DFB Laser Diode Module

The company will feature the SCW 1731F-D40R proprietary laser diode module at LASER World of PHOTONICS, June 24 - 27, 2019, in Munich, Germany, in Hall B2, Booth 139.

EDISON, New Jersey – OSI Laser Diode (LDI), a leading global supplier of advanced optoelectronics components, introduces a 1650 nm AI RWG DFB laser diode module. The SCW 1731F-D40R is specially designed for optical test equipment applications where high-peak-pulsed optical power is required.

The laser diode module’s unique proprietary design offers a stabilized wavelength that is unaffected by operational pulse width, making it ideal for OSA/OTDR tasks. The module also features a broader spectrum than is available in traditional DFBs and it exhibits less noise in OTDR and other similar applications.

The new product, housed in a 14-pin DIL package, is RoHS compliant. It is optically coupled to an SMF fiber pigtail and includes a thermoelectric cooler and an electrically-isolated temperature-sensing thermistor.

The SCW 1731F-D40R is available for immediate delivery. For more information and to download the data sheet, please visit:

The product will be showcased in Hall B2, Booth 139 at the 24th Annual LASER World of PHOTONICS in Munich, Germany, June 24 - 27, 2019.
