FIRECOMMS RCLED-BASED MOST® DEVICES RECEIVE AUTOMOTIVE CERTIFICATION

Cork, Ireland — February 2, 2006 — Firecomms Ltd. today announced that its MOST® fiber optic transceiver (FOT) based on a high-speed resonant cavity LED has been certified by RMCtech for compliance with the MOST® (Media Oriented Systems Transport) standard, making it the first RCLED-based FOT to receive this certification.

RMCtech granted certification after completing a series of rigorous reliability and compliance tests. The independent, accredited firm tested all required functions of the RCLED FOT for compliance with the MOST specification.

“Not only did Firecomms’ FOT easily pass the rigorous certification tests, these devices delivered an additional 8dB of optical power over the specification,” says Firecomms Project Manager Brian McGarvey.

Firecomms’ FCM110R transmitter and FCM110D receiver are state-of-the-art four-pin, low-cost plastic packaged components that meet the MOST 1.1 physical layer specification for the POF optical interface. Digital input/output data conforms to TTL switching levels.

The transmitter uses a novel high-speed RCLED source with an integrated lens designed to maximize coupling efficiency. This source provides high optical power of greater than -7 dBm with a low operating current of less than 25mA, and fast rising and falling optical edges of less than 4.2 nanoseconds.

“The optical budget provided by the Firecomms MOST FOT allows us to target higher temperature performance,” says Firecomms CEO Declan O’Mahoney. “This enables our customers to use extra inline connectors, and develop more efficient car harnesses. And because RCLEDs are five times faster and more efficient than LEDs used in competitors’ devices, we can demonstrate high-speed future proofing for the automotive industry up to 250Mbps.”

Firecomms RCLED FOTs incorporate CMOS chips made by Nanotech Semiconductor, fine-tuned in collaboration with Firecomms for optimum performance with its MOST RCLED. The chipset is a result of the collaboration between the two companies.

Detailed specifications for Firecomms’ MOST FOT are available on the company web site at www.firecomms.com. This device can be ordered through Firecomms’ sales organization (sales@firecomms.com) in Japan, USA, and Europe.
