The chipset will be used in a 40G Quad Small Form-factor Pluggable (QSFP) Active Optical Cable (AOC) application.
GigOptix’s HXT/R4 chipset has been designed to support multiple applications ranging from 5Gb/s to 10Gb/s per channel. The advanced feature set of the HXT/R4 family enables customers to optimise the trade-off between power dissipation and performance of the optical link. This has been successfully demonstrated by transmitting data over a 100m link with less than 100mW total power dissipation.
Moreover, GigOptix’s unique architecture enables customers to examine the detailed status of their product after the fibre has been attached. This functionality allows customers to more easily test and monitor the operation of the VCSEL and Photo Diode devices within the optical engine leading to significant cost savings.
Jay de la Barre, GigOptix’s Vice President of Global Sales stated, “We believe that our HXT/ R4 chip-set will be key to enabling 40G optical engines for the high volume supercomputing and consumer markets. We are very excited to work with pioneering companies using innovative silicon bench technology along with our VCSEL driver and receiver array chip-set to take their solutions to production.”
The HXT/R4 chip-set is designed for use in Infiniband AOC, SNAP12 and QSFP optical modules while serving the fast growing markets of high performance computing optical interconnects, switch and router optical backplanes and the emerging 40G and 100G Ethernet standards.
NeoPhotonics quadruples capacity to cope with ICR demand
The company is responding to increased demand for volume shipments of high-speed coherent fibre optic transport systems.
Photonic Integrated Circuit manufacturer NeoPhotonics, which provides PIC based modules and subsystems for bandwidth-intensive, high
speed communications networks, has quadrupled capacity for PIC-based Integrated Coherent Receivers (ICRs) for state-of-the-art 40 and 100Gbps coherent fibre optic transport systems.
The Company believes that the industry is coalescing behind the “coherent technology” approach for high-speed “backbone” networks. By combining the NeoPhotonics PIC-based ICR, which has one of the industry’s highest signal detection responses, with advanced digital signal processing on each channel, the coherent approach is designed to provide service providers a solution for leveraging their existing fibre optic cable investments longer, more efficiently and in an “on demand” manner.
“The rapid increase in the use of coherent transmission technology for 40 Gbps on the line side, coupled with an initial ramp of 100 Gbps coherent systems, necessitates a significant increase in volume shipments of ICRs while maintaining stringent optical performance requirements,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “Our photonic integration technology utilises our semiconductor-based wafer manufacturing capabilities and is inherently high quality, scalable and cost-effective, which positions us ahead of the demand curve for this important technology,” concluded Jenks.
The NeoPhotonics ICR is designed to convert the phase encoded optical signals into electrical signals of varying intensity, which can then be analysed using digital signal processing. As carriers upgrade from 10 Gbps network connections, the coherent solution utilizing the NeoPhotonics ICR not only provides more throughput capacity but also more intelligence. NeoPhotonics has earned multiple design wins for the ICR with its tier 1 customer base and is now shipping ICR products, with or without an internal polarising beam splitter, to multiple customers.
The NeoPhotonics ICR is designed to support the OIF Implementation Agreement for Integrated Dual Polarization Intradyne Coherent Receivers. The PIC-based ICR is designed to provide advanced demodulation to analyse the state-of-polarisation and optical phase of a phase-modulated signal relative to an externally supplied optical reference signal, enabling recovery of the phase-polarisation constellation of 40 or 100 Gbps format signals.
