The authors have developed fiber optic transceivers (FOT) based on leadframe and molding technology for large core PCS optical fiber systems. The transmitter module contains a VCSEL light source, an electronics driver chip, and some passive electronics components. The operating wavelength range of the laser chip is in the near infrared at 850nm. An internal control circuit stabilizes the optical output power over the entire operating temperature range from -40degC to +105degC to within 1dB variation. Eye diagrams taken at 500Mbps are wide open from -40degC to 105degC. The extinction ratio is larger than 10dB and the rise and fall time in the order of 0.5ns. The FOT is highly reliable and stable over 1000 temperature cycles from -40degC to 125degC. For the receiver side the authors developed high speed MSM photodetectors. The large area MSM photodetectors relax the coupling alignment tolerance to the core of the optical fiber. The MSM photodetector is capable of data rates of 3.2Gb/s. At this high speed the sensitivity is better than -18dBm for the MSM photodetector co-packaged with a suitable transimpedance amplifier (TIA). The technology meets the requirements of current and future infotainment networking applications.
