Modulight adds wavelengths to fiber pigtailed laser diode lines

Feb. 28, 2006
February 28, 2006 Tampere, Finland -- Modulight's 1550-nm FP and DFB laser diodes for analog applications are based on the company's analog 1310-nm FP and DFB laser diodes. The company says these long-wavelength lasers can be combined with the 1310-nm lasers for bi-directional transmission over single fiber, or can be used independently for longer span lengths than can be obtained with 1310-nm.

February 28, 2006 Tampere, Finland -- Modulight's 1550-nm Fabry-Perot (FP) and distributed feedback (DFB) laser diodes for analog applications follow company's analog 1310-nm FP and DFB laser diodes. The company says these long-wavelength lasers can be combined with the 1310-nm lasers for bi-directional transmission over single fiber, or can be used independently for longer span lengths than can be obtained with 1310-nm.

The company says the products can be used to increase the transmission capacity and reach of fiber-optic links in wireless repeaters, video surveillance systems, RF-over-fiber and hybrid-fiber-coax (HFC) networks, where good carrier-to-noise ratio is critical. The company says its DFB laser diodes with eight CWDM wavelengths ranging from 1470-nm to 1610-nm with 20-nm spacing are designed for digital modulation with up to 2.5 Gbit/sec signaling rate.

The company says that all of its uncooled, hermetically sealed, coaxial fiber pigtailed DFB lasers feature high side mode suppression, low distortion, and low RIN. The company says its FP lasers offer a cost-efficient platform for applications with relaxed requirements for spectral purity. Lasers are available with or without and integrated optical isolator and with a variety of connectors.

The company will feature the products at next month's OFC exhibition in Anaheim, CA.
