Optical Receiver

The R768 is a 40-gigabit-per-second (Gbit/s) optical receiver that enables systems to operate up to four times faster, meeting capacity demands in high-speed optical transport backbone networks.

The device receives and converts streams of light pulses carrying voice, video and data signals into electrical signals. The receiver uses a waveguide positive intrinsic negative (PIN) detector to convert the light into electrical current. It then uses a multi-functional integrated circuit (IC) as a preamplifier to strengthen the received signal for further processing. The device can be used in long-haul and submarine transport networks and is ideal for line terminal and digital video equipment, and very high-speed router-to-router connections.

The receiver consists of a high-speed photodetector and a wide-band linear preamplifier in a pigtailed metal package with a single-ended V-connector. It is designed for use in single-mode, high-speed telecommunications applications at the synchronous optical networking (SONET) OC-768 and the synchronous digital hierarchy (SDH) STM-256 data rate of 42.5 Gbit/s.

The receiver is manufactured in a compact 16-pin package, and requires only a six-volt power supply. It is fully operational through the L-band (1.6-micron) wavelength range.
