Vitesse and AraLight Collaborate on Reference Platform for Optical, SAN and Video Applications

9/18/2002 - Vitesse Semiconductor announced it has partnered with AraLight, a provider of high-density opto-electronic interconnect solutions, to develop a modular switching evaluation platform for high-speed backplane applications. The reference platform enables designers to address the demands for increased bandwidth for high-performance Enterprise, Metro and Core infrastructure networks. OEMs can use the switching systems for optical, SAN and video applications. The reference design platform utilizes the VSC3139, a 72x72 crosspoint switch from Vitesse, and the AraLight ARL-36 Series (36 TX and 36 RX channels) transceiver.

The platform offers an end-to-end solution that will lower system cost by up to 30 percent and reduce the switching board footprint by 50 percent. Testing of AraLight's 36-channel optical transmitter and receiver with Vitesse's 72-channel crosspoint switch concludes this solution can meet and exceed SONET OC-48 and 10 Gigabit Ethernet Standard (IEEE 802.3ae) requirements. In place of using Clock and Data Recovery (CDR) circuits, these results were achieved by combining Vitesse's proprietary Integrated Signal Equalization (ISE) capabilities of the VSC3139 with the low-jitter ARL-36 modules in a system with printed circuit boards with trace lengths of 70 inches and multi-mode fiber lengths of 400 meters. Vitesse's ISE technology enables the signal to be driven across long traces of microstrip on FR4 printed circuit board material, without adding power or board space typically associated with CDRs or retimers. By eliminating the need for retiming, system developers can achieve complete data rate transparency and minimize switch latency.

"Vitesse and AraLight have built a reference design that enables OEMs to easily incorporate optical links into a switching system without compromising signal integrity," said Gary McCormick, product line director from Vitesse. "We are excited to have the opportunity to demonstrate this reference platform at the NFOEC tradeshow in Dallas."

The reference design platform is now sampling and will be demonstrated in Vitesse's booth (#3408) during NFOEC in Dallas, September 16-18, 2002.

"We believe that tighter integration between optical and electrical circuits will be essential to reducing system cost. The AraLight-Vitesse reference platform is an important first step in this direction," said Ashok Krishnamoorthy, AraLight CEO and founder.

About AraLight
AraLight Inc. develops, manufactures and markets high-density opto-electronic components and subsystems that reduce the cost of installing, operating, and maintaining carrier networks. Headquartered in Monroe Twp., NJ, the company provides optical interconnect solutions for the telecom and datacom equipment in the access, metro, and core networks. The company has its roots in Bell Laboratories, where the AraLight team built up a combined 150 years of experience and guided a $35 million research and development budget. Lucent Technologies spun out AraLight and the entire Bell Labs team in September 2000. Investors include Ridgewood Capital, Signal Lake Ventures and New Ventures Partners LLC, formerly the New Ventures Group at Lucent Technologies (NYSE: LU).
