OSI unveiling 1490nm pulsed laser diode modules for optical testing

In booth 102 (Hall A2) at LASER World of PHOTONICS 2015 at Messe München in Germany (22-25 June), OSI Laser Diode Inc (LDI) of Edison, NJ, USA is premiering its SCW 1430 series of laser diode modules.

Operating typically at a center wavelength of 1490nm (1470nm minimum to 1510nm maximum), the Al RWG (ridge-waveguide) FP (Fabry-Perot) laser diode series is designed for optical testing applications where high peak pulsed power is required, such as optical time-domain reflectometers (OTDRs) and optical spectrum analyzers (OSAs).

Four RoHS-compliant packages are available: 14-pin dual in-line (DIL), 14-pin butterfly, 3-pin coaxial or 3-pin transistor outline (TO56). The high-peak pulsed laser diode modules deliver at least 100mW of optical power (fiber) and a minimum of 300mW (TO56). The higher power is said to offer greater dynamic range capability to OTDR manufacturers. The SCW 1430 series also features what is claimed to be excellent pulse drift performance and high stability.
