Semtech serves the emerging, short-reach, metropolitan and long-haul optical network markets as a supplier of 40Gb/s and 100Gb/s MUX/DEMUX chipsets. JDSU provides integrated 40Gb/s and 100Gb/s optical-to-electrical and electrical-to-optical conversion tools for these markets.

“Explosive video, voice, and traffic demands, including HDTV, interactive TV, streaming video, and 4G, are placing extreme pressures on global carriers to deliver ultra-high bandwidth quickly and in a cost effective, efficient, and reliable way,” says Sameer Vuyyuru, vice president and general manager for Semtech’s Transport and Data Communication Group. “JDSU is at the forefront of this wave with a commanding product breadth and depth of technology and we are proud to be designed into their leading-edge 40G transponders.”

“Semtech is a key vendor for JDSU with their MUX/DEMUX solutions at 40G and beyond,” says John Kavanagh, vice president of supply chain for JDSU’s CCOP division. “40G technology is technically challenging and requires high-level skill sets in analog design, as well as in packaging and testing.”

JDSU’s 40Gb/s transponder employs Semtech’s SMI4027 MUX and SMI4037 DEMUX chipset to convert data signals from electrical to optical formats and back again. The SMI4027 multiplexer includes an on-chip clock multiplier unit (CMU) that supports data rates from 39.8 to 44.6Gb/s and combines 16 lanes of 2.5Gb/s incoming data signals into four lanes of 10Gb/s each to enable fast, reliable data transport over optical fiber.
The SMI4037 demultiplexer accepts both single-ended and differential 39.8 to 44.6Gb/s bi-directional NRZ serial data streams and separates (demultiplexes) the data signals into 16 parallel output channels on the outbound transmission side.
