Firecomms unveils transceiver for in-car networks
Firecomms, an Ireland-based developer of high-speed semiconductor light sources, says that it has unveiled the world's first media orientated system transport (MOST) fiber optic transceiver based on a high-speed resonant cavity LED.
MOST networks are plastic optical fiber-based infrastructures deployed in cars to provide communication between various electronic systems, that offer a low-cost alternative to copper cabling.
Firecomms' transmitter uses a resonant cavity LED (RCLED), which is a device that is similar to a VCSEL and contains two distributed Bragg mirrors. The RCLED is integrated with a lens to maximize coupling efficiency.
The source provides more than "“ 7dBm of optical power at an operating current of 25 mA. The receiver is a CMOS design with a sensitivity of "“ 28dBm.
"Our RCLED technology offers improved device efficiency, high bandwidth (to 250 Mb/s), and excellent reliability," remarked Firecomms CTO John Lambkin.
"Because out core light sources are significantly faster than existing fiber optic transceivers, we can provide our customers with the ability to migrate to next-generation systems while maintaining existing connectors and a plastic optical fiber architecture," added the company's CEO Declan O'Mahoney.
