21 Sep 2007 Finisar Ships Industry’s First Fabry-Perot Laser DiodeOptical Components for 10GBASE-LRM Applications Finisar Corporation (NASDAQ: FNSR), the world leader in fiber optic solutions for high speed communication networks, today announced availability of the industry’s only transmitter and receiver optical subassembly pairs (TOSA/ROSA) for the IEEE 10GBASE-LRM standard using Fabry-Perot lasers and PIN detectors. Several innovations introduced with these devices extend performance, conserve power, and expand control.
To date, LRM products on the market have been based on more expensive and power hungry Distributed Feedback Lasers (DFB). Finisar’s Advanced Optical Components TOSA utilizes Fabry-Perot laser diodes which are inherently less expensive but still able to meet all the performance requirements of the IEEE 10GBASE-LRM standard. In addition, Fabry-Perot laser diodes substantially reduce overall transceiver power consumption.
Within the ROSA, automatic gain control and receive-signal detect capabilities enable developers to optimize individual link performance and implement intelligent fault detection. Within the TOSA, a unique impedance matching network reduces power consumption. Additionally, the TOSA and ROSA are offered in two connector options (SC and LC) and include a flex circuit for simplified electrical connectivity.
“Our Fabry-Perot-based products continue Finisar’s tradition of offering high reliability, competitive pricing, and high-volume manufacturing while meeting customers’ stringent performance requirements,” said Dr. Jim Tatum, director of marketing for Advanced Optical Components at Finisar. “These new 1310 nm LRM subassemblies are important additions to Finisar’s existing portfolio of 850nm short reach products. They further enhance Finisar’s position as a market leader in short-reach optical subassemblies.”
The 10Gb LRM TOSA and ROSA pairs are available today for evaluation or high-volume production. Custom solutions are also available.
