Demonstration of a Low Cost, High-Speed Fiber Optic Transceiver

摘要

A high-speed serial optical link suitable for a range of commercial and military short-haul applications, operating over a distance of up to 300 meters was developed. At the heart of the link lie a vertical-cavity surface- emitting laser (VCSEL) diode transmit and a gallium arsenide (GaAs) photo detector, driven and amplified by custom-designed GaAs integrated circuits. The transmit or receiver is individually hermetically sealed in a metal-ceramic surface-mounted package with a multimode fiber pigtail aligned to the laser or photodiode respectively. The transmitter and receiver are nearly identical externally and each is less than 0.2 cm in volume. The link is capable of> 10 gigabit per second operation, independent of signaling protocol and can transmit over distances of up to 300 meters on high-bandwidth multimode fiber.
