Semtech 40G MUX/DEMUX Platform Enables JDSU 40G Metro Optical Network Transponder Solutions08:00 EST Monday, March 07, 2011 CAMARILLO, Calif. (Business Wire) -- Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced they have successfully integrated Semtech's 40Gb/s multiplexer (MUX)/demultiplexer (DEMUX) chipset platform into JDSU's 40Gb/s DWDM transponder modules. Semtech is a leader in the emerging, short-reach, metropolitan and long-haul optical network markets as a leading supplier of 40Gb/s and 100Gb/s MUX/DEMUX chipsets. JDSU is a leader in integrated 40Gb/s and 100Gb/s optical-to-electrical and electrical-to-optical conversion solutions 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,” said 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. We look forward to a long and rewarding relationship,” concluded Vuyyuru. “Semtech is a key vendor for JDSU with their MUX/DEMUX solutions at 40G and beyond,” stated 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.
