OEpic unveils 10-Gbit/sec optical front-end TOSA/ROSA for legacy fiber upgrades

17 December 2003 Sunnyvale, CA Lightwave -- OEpic Inc. has introduced a Legacy-10G line of products consisting of 10-Gbit/sec 1310-nm optoelectronic front-end TOSA/ROSA solutions for small form factor transceivers in 62.5-micron legacy fiber applications.

The transmitter/receiver pair incorporates OEpic's proprietary flex board interconnection technology (TO Flex) for low cost, next-generation 10-Gbit/sec optical transceivers, such as XENPAK, X2, XPAK, and XFP. When used with electronic dispersion compensation (EDC) enabled transceivers, OEpic's TOSA/ROSA front-end can provide error-free 10-Gbit/sec serial transmission over up to 300 m of legacy multimode fiber. "Our new TOSA/ROSA optical front-end provides a low-cost solution for upgrading existing 1-Gigabit Ethernet multimode fiber networks to 10 Gbits/sec. We are working with the leading EDC chip vendors and have demonstrated greater than 300 m of error-free transmission over 62.5-micron fiber using our optical front-end parts," reports Dr. Yi-Ching Pao, founder, president and CEO of OEpic. "As the IEEE 802.3 standards for legacy fiber move forward, we expect OEpic's new 1310-nm Legacy-10G products to lead to rapid and cost-effective upgrades to 10 Gbits/sec."The LF1030-LCF11 TOSA consists of a 1310-nm Fabry Perot (FP) laser coupled to a singlemode fiber stub, facilitating offset launch into multimode fiber. Another version of this module (LF6230-LCF11) utilizes direct coupling to multimode fiber with restricted launch for controlled modal dispersion. This is the preferred solution pending the adoption of restricted launch criteria by IEEE standards committees.The PT 6232-LCF11 ROSA consists of a 1310-nm PIN photodetector with high optical collection efficiency and a highly linear TIA. Oepic contends its proprietary high-linearity TIA and PIN photodetector provide a larger linear dynamic range than other competitive solutions for legacy fiber applications.The LF1030-LCF11 TOSA and the PT6232-LCF11 ROSA and evaluation boards are now available for sampling and evaluation. The LF6230-LCF11 TOSA will be available in Q1 of 2004. Volume quantities will be available in Q2 of 2004. In production volumes, the price of the TOSA/ROSA pair is under $150.
