July 26, 2010... Innolume, a maker of Quantum dot-based diode lasers with headquarters in Dortmund, Germany announced that it has begun sampling the LD-12xx-series laser platform for a new generation of pump laser. The LD-12xx-series is based on the company’s proprietary Quantum Dot epitaxial technology.

The company says that the series is designed as a pump source for O-band Raman amplification, and it features a single mode output of 300 mW at 1100 mA, centered at 1240 nm or 1260 nm. The series is packaged in a 14-pin butterfly and is optionally equipped with a polarization maintaining fiber (PMF) as well as a fiber Bragg grating (FBG) to achieve high stability of output power and spectrum.

The company points to the laser pump source for its application in Passive Optical Network (PON) technologies to help meet the subscribers’ increasing demand for high bandwidth services. Guido Vogel, VP of Business Development at Innolume commented, "Deployment of distributed Raman-amplified GPON technology based on our LD-12xx-series lasers will offer network operators the option to extend network reach while saving on CAPEX and OPEX. Installing the amplifier unit at the Central Office significantly reduces maintenance costs versus powered extender boxes in the field, which are generally impractical, particularly for rural deployments.”
