Palo Alto, Calif. The MDA-1220-08S surface-mount optical amplifier drives electro-absorption (EA) and lithium-niobate (LiNbO3) Mach-Zhender modulators. Housed in an 11.354 x 4.318 x 17.247-mm package, the driver amp can be used in OC-192/STM-64 systems operating with or without FEC protocols. The amplifier sits between mux chips and the modulator to amplify non-return-to-zero (NRS) and RZ signals from 9.953 to 12.5 Gbit/s. The amp sports 20-dB typical gain, an output voltage up to 7.5 V peak-to-peak, a 15-ps rise time, and +/-1.5-dB gain ripple.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
