Abstract

A 1.25Gbit/s burst-mode optical transceiver for Ethernet Passive Optical Network (EPON) system has been developed using a 0.25 μm CMOS technology. With new automatic gain control technique and reference-voltage generator, the optical receiver achieved wide dynamic range of 26.3dB with sensitivity of -29.0dBm and overload of -2.7dBm at 1.25Gbit/s burst-mode transmission. Moreover, coming up with a novel automatic power and extinction ratio control method, the optical transmitter successfully suppressed their variations within ±0.4dBm and ±0.6dB respectively in wide temperature range from -40 to 100°C.
