Diode Laser Modules

DILAS Diode Laser Inc. (Tucson, AZ) introduced a line of fiber-coupled diode-laser modules delivering up to 40 W continuous-wave output power at wavelengths of 808nm, 915nm, 940nm,and 980nm via a 400μm-diameter, single-core, multi-mode fiber. Measuring less than100 × 31 × 20 mm and having a wall-plug efficiency of less than 35%, the spectral width is less than 3 mm, FWHM. The laser power from the module is delivered via the fiber, which is terminated with a standard SMA 905 connector. The unit is available in an overall height of less than 30 mm including optional features such as power monitor and temperature sensor.

Optical Fiber Backlighting

Lumitex, Inc. (Strongsville, OH) released a family of products — BendiGloTM, HoloGloTM, CircleGloTM, and Selective LightingTM — based on their existing UniGloTM technology to backlight shapes such as rectangles, ovals, circles, semi-circles, holes, and other unusually shaped geometries. Optical fiber is mounted on a back reflector to create lighting panels of 0.33 mm. BendiGlo is for hard-to-reach areas in membrane switches; HoloGlo follows paths around/between shapes and die-cut holes; CircleGlo is used in one to three layers for circular areas with a hole; and Selective Lighting creates selective area panel lighting.

LED Drivers

Endicott Research Group (Endicott, NY) released the Smart ForceTM family of LED driver solutions for high-bright LEDs (HBLEDs) used in LCD backlighting applications. Available as a LED driver board or a complete kit including driver board and LED rails, the product has input voltages of 12 V, 24 V, or 48 V (measuring 33 × 60 mm) in single-, dual-, or three-channel versions. Employing a DC-DC boost to provide voltage to a constant current driver and LED rail, the driver boards’ input voltages range from 5 V to 48 V. Standard features include separate enable/disable and PWM dimming controls.

Test Module

EXFO Electro-Optical Engineering Inc. (Quebec City, Canada) introduced the FTB-8105 T-Carrier/PDH Transport Blazer test module as part of the Transport Blazer line. The unit tests digital-signal levels and plesio-synchronous digital hierarchy electrical rates as well as SONET/SDH rates up to 155 Mbps, and is suited for time-division-multiplexing field service deployment and maintenance applications. The module may be combined with the FTB-8510 Packet Blazer Ethernet module for Ethernet-over-TDM network deployments.
