Fibre Channel devices drive towards
8Gbit/s
Integrated drivers and limiting amplifiers are designed to meet the need for backwards compatibility in the imminent 8G Fibre Channel market.
Phyworks is extending its Fibre Channel product line to 8Gbit/s with two key new products in development: the PHY1080 is an 8G integrated VCSEL driver and limiting amplifier designed for short-wavelength multimode applications; and the PHY1085 is an 8G integrated laser driver and limiting amplifier designed for long-wavelength single-mode applications Phyworks' new products are designed to meet the need for backwards compatibility in the imminent 8G Fibre Channel market

Kits accelerate fibre-optic module design
A new range of reference design kits aims to simplify the implementation of 1-4Gbit/s SFP fibre optic modules for Gigabit Ethernet, Fibre Channel and Sonet/SDH applications.
Driver receiver ICs cut laser modules down to size
New monolithic laser and VCSEL driver/receivers from Phyworks replace two devices in a standard SFF/SFP optical module.
Current 8G module prototypes have been designed using high specification 10G drivers and post amplifiers.
The PHY1080 and PHY1085 offer highly integrated transmitter and receiver functionality, reducing cost for both optical module manufacturers and end users.
Phyworks, already a leading supplier of highly integrated 1-4Gbit/s Fibre Channel solutions, is also the world leader at 10Gbit/s with its 10G LRM compliant EDC IC.

Transimpedance amps run from 1 to 4Gbit/s
Phyworks has expanded its family of transimpedance amplifiers for application in fibre-optic modules from 1 to 4Gbit/s.
The company is drawing on experience from both the successful integration of driver and receiver ICs at 4Gbit/s, and innovative solutions to the 10G challenges, in developing high performance ICs which will facilitate the 8G Fibre Channel market.
The T11 standards group are currently nearing completion of the FC-PI4 8G Fibre Channel standard which will drive the 8G Fibre Channel market.
Commenting on the market, Lawrence Gasman of Communication Industry Researchers Inc (CIR), predicted: "The market for 8Gbit/s Fibre Channel ports will exceed five million units by 2011".
Gasman notes: "The initial driver for 8Gbit/s FC will be for interswitch links in networks with a growing number of 4Gbit/s, after which 8Gbit/s ports will become the choice on the client side".
Additionally, the SFP+ multisource agreement, expected in 2007, will drive the move to 8Gbit/s, with high port density applications leading the way.
Phyworks' solution will feature a backwards compatible limiting receiver architecture, designed to meet all requirements for the SFP+ form factor.
In order to meet the lower power and smaller size requirements of optical module vendors, the PHY1080 and PHY1085 will be developed as highly integrated, multirate products offering a range of features to meet the needs of multiple system environments.
EMI emissions are minimised, aiding and simplifying the transceiver qualification and design-in process by implementing transmit and receive edge rate control.
End users will also benefit from guaranteed optical compliance over environmental conditions and lifetime, whilst further reducing transceiver manufacturing costs by removing the need to setup and test transceivers over temperature.
The new products will enable optical module vendors to meet all Fibre Channel link lengths in the most cost effective way.
By offering VSCEL and laser versions of the highly integrated IC, with identical pin outs, optical module manufacturers will be able to design a complete Fibre Channel product portfolio using a single platform.
Brad Weaterton, Phyworks Director of Marketing, commented: "Phyworks has always been committed to providing our customers with highly integrated and high performance solutions which reduce design time and manufacturing costs".
"Similar to our 4G product family, these two new ICs, along with our PHY1090 TIA already being used in most 10G LRM applications, will give customers a clear competitive advantage in a highly cost sensitive market".
"Our products will allow for the swift transition from 4GFC to 8GFC and without the need for optical module manufacturers to invest millions of dollars in internal IC developments to create the most cost effective and highest performance solutions".
The PHY1080 and PHY1085 will be available in RoHS compliant, industry standard QFN packages.
Phyworks expects silicon to be available by the end of 2006.
The PHY1080 and PHY1085 will be sampled with an SFP+ reference design, and, as with all Phyworks products, full applications support.
