JDSU’s 40G DWDM transponder uses Semtech’s MUX/DEMUX chipset

Semtech Corp of Camarillo, CA, USA, a supplier of analog and mixed-signal semiconductors for high-end consumer, computing, communications and industrial equipment, has integrated its 40Gb/s multiplexer (MUX)/demultiplexer (DEMUX) chipset platform into JDSU’s 40Gb/s DWDM transponder modules.

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

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.

“Semtech is a key vendor for JDSU with their MUX/DEMUX solutions at 40G and beyond,” states John Kavanagh, VP of supply chain for JDSU’s Communication & Commercial Optical Products (CCOP) division. “40G technology is technically challenging and requires high-level skill sets in analog design, as well as in packaging and testing.”

“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, VP & 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... We look forward to a long and rewarding relationship,” he adds.
