Live demonstration emphasizes the potential of photonic integrated circuits
to drive down the cost per bit at 100Gb/s and beyond
FREMONT, CA – September 22, 2008 – Santur Corporation, a worldwide leading supplier of integrated photonic devices will demonstrate 100Gb/s transmitters and receivers based on indium phosphide (InP) laser and detector arrays at the European Conference on Optical Communications (ECOC 2008) in Brussels, Belgium. These devices are based on a transmitter that integrates a DFB (Distributed Feedback) laser array with a matched PLC (Planar Lightwave Circuit) multiplexer, and a receiver that integrates a photodiode array with a matched PLC demultiplexer. The high level of integration eliminates the need for multiple single channel discrete devices and fiber couplings found in traditional photonic components. Unlike parallel 10x10Gb/s technologies based on ribbons of multi-mode fiber (MMF), the Santur transmitters and receivers operate over one conventional single-mode fiber (SMF) with longer reach. Compared to other 100Gb/s SMF optic links, the demonstrated technology does not require complex modulation schemes or gearbox ICs for conversion to intermediate 25Gb/s lanes.
As a result of its focus on leading edge integrated InP devices, Santur has a very significant leadership position in the tunable laser market. Currently there are nearly 200,000 Santur tunable lasers based on integrated laser arrays deployed in long-haul and metro networks around the world. The ability to make low cost devices in array form allows Santur to develop a robust Photonic Integrated Circuit (PIC) platform that delivers from 40 Gb/s to 400 Gb/s. Integrated photonic devices, like those shown in this demonstration, deliver the value of photonic integration including increased density, lower cost, reduced power consumption and enhanced reliability to system integrators.
Based on 10 electrical lanes operating at 10.3Gb/s, the live demonstration showcases the WDM (Wavelength Division Multiplexing) transmission of 100Gb/s protocol compliant data streams over up to 10Km SMF. The technology simplifies the upgrade of 10Gb/s channels in access networks, enterprise core networks, and addresses fiber exhaustion in data centers.
Bardia Pezeshki, Chief Technology Officer of Santur stated “the economics
of integrating multiple optical devices onto a single chip gives us
very significant opportunities to continue to drive performance while
keeping cost down. This solution is optimized to address the near term
need for higher data rates for a wide variety of high growth applications.”
In
addition to the live demonstration of 100Gb/s Photonic Integrated Circuit
technology, Santur will be showcasing its broad portfolio of solutions
including narrow linewidth tunable laser solutions for 40G and 100G
networks and highly integrated low profile tunable transmitters. Santur
representatives will be at ECOC booth M9 from September 22-24.
