FP and DFB Laser Diodes for Analog Apps
Feb 2006
Modulight Inc.Request Info
SAN JOSE, Calif., Feb. 24, 2006 -- Modulight has introduced 1550-nm Fabry-Perot (FP) and distributed feedback (DFB) laser diodes for analog applications following the release of its analog 1310-nm FP and DFB laser diodes. These long-wavelength lasers can be combined with the 1310-nm lasers for bidirectional transmission over single fiber, or they can be used independently for longer spans than those obtained with 1310 nms. The new products can be used to increase the transmission capacity and reach of fiber optic links in wireless repeaters, video surveillance systems, radio frequency-over-fiber and hybrid-fiber-coax networks -- where good carrier-to-noise ratio is critical.

DFB laser diodes with eight coarse wavelength division multiplexing (CWDM) wavelengths (from 1470 to 1610 nm) with 20-nm spacing are designed for digital modulation with up to a 2.5 Gb/s signaling rate.

Modulight said its uncooled, hermetically sealed coaxial fiber-pigtailed DFB lasers feature high side mode suppression, low distortion and low RIN (relative intensity noise). FP lasers offer a cost-efficient solution for applications with relaxed requirements for spectral purity. Lasers are available with or without an integrated optical isolator and with a variety of connectors.

The company will exhibit at OFC/NFOEC, to be held March 5-10 in Ahaheim, Calif.
