Phyworks' extend FTTx Transceiver and TIA family

With the passive optical networking (PON) expected to rise to 32 million subscribers by 2009, network operators are continually seeking ways in which to make their solution more efficient. The extension of Phyworks FTTx product line enables this. Phyworks has developed a complete family of devices, making up specialised solutions designed to optimise all segments of the FTTx market.

Phyworks’ release of the PHY2078 broadens their product group offering of FTTx Burst Mode Laser Driver and Limiting amplifiers. Following the successful launch of the PHY1078 GEPON optimised solution last year, the PHY2078 is designed for the higher bandwidth 2.5Gbps GPON (Gigabit Passive Optical Network) ITU G.984.2 standard.

The PHY2078 can be combined with a microcontroller to allow module vendors to support digital diagnostic monitoring (DDM), allowing the key performance parameters of the device to be monitored throughout its lifetime in compliance with the SFF 8472 standard. The PHY2078 can also be used in triplexer applications where the DDM software enables monitoring of the video path optical input power, video amplifier gain control, and video path RF power sensing.

The PHY2078 encompasses features such as an on chip state machine, a digitally controlled Automatic Power Control (APC) loop to accurately control the Laser transmission characteristics, a high sensitivity receive path with user programmable filter characteristics and very low cross talk.

The PHY1095 and PHY1097 transimpedence amplifiers (TIAs) complement the transceiver ICs by offering the user economical efficiency through exceptionally high sensitivity and low noise. The devices offer compatibility to the GPON and GEPON markets and are capable of high sensitivity performance without the added cost of an avalanche photodiode (APD) circuit, which would typically add up to $20 USD to the complete solution.

The PHY1097 is designed for GEPON and GPON operating at up to 2.5Gbps. This device reaches exceptional sensitivity of -29dBm and low input referred noise of 150nA.

The PHY1095, which operates at up to 1.25Gbps, servicing the GEPON sector of the market, also reaches industry leading performance of -32dBm sensitivity coupled with low 60nA of input referred noise.

Both devices offer overload levels of +4dBm, selectable RSSI output current direction, and data polarity for ease of module design and manufacture.

On the announcement of the completion of both GPON/BPON and GEPON chip sets Stephen King, Phyworks CEO, commented “We are confident the performance of these products is market leading. Having gained a significant number of key design wins for the PHY1078 GEPON transceiver and TIA’s in both US and Asian markets, we now feel we have the most complete and technically advanced solution in the industry.”

Brad Weaterton, Phyworks Director of Marketing added “Phyworks are pleased to be able to bring such high performance products to the market. We continue to dedicate resources to R&D and fully supporting our customers.”
