Avago's industrial fibre receivers deliver 50 MBd links
Avago Technologies is announcing the availability of production volumes of a family of 50MBd - 820nm integrated fibre optic receivers for communication and control networks within power substation, smart grid and industrial automation applications.
Traditional 5MBd optical networks are no longer fast enough for substation automation and smart grid implementation. More control data and equipment need to be connected within the network requires higher bandwidth components to ensure reliability and safety, therefore equipment manufacturers are looking towards 50MBd links, but existing products require many external components.
This new receiver provides the desired 50MBd link speed while integrating external receiver IC functions into the fibre optic receiver, saving one external IC and 18 discrete components. AFBR-24x9xZ is designed to provide cost-effective and high-performance fibre optic communication links with EMI resistance by utilising state-of-the-art technology that has an integrated photodiode with digitalizing IC on the same silicon chip. The fibre optic receiver part is designed to operate with fibre optic transmitters HFBR-14xxZ and HFBR-1712TZ with link distances of up to 3km on multimode glass fibre cable. AFBR-24x9xZ is directly compatible with popular industry-standard ST and SMA connectors, and it operates from 100kBd up to 50MBd of transmission signal. With this operating frequency range, this product can be used for implementing proprietary fibre optic transmission system up to 50MBd and 10Base-FL.
AFBR-24x9xZ has made the system engineer's job easier with such integration of photodiode and digitalising IC. This is because it saves more than 75 per cent of components used in similar application and provides excellent EMC performance. It also consumes less than 20 per cent of the total power dissipation when comparing with the existing products for 10Base-FL application in the market. AFBR-24x9xZ is equipped with RSSI (Received Signal Strength Indication) feature that indicates the signal strength of the incoming optical signal for diagnostic function.
AFBR-24x9xZ product family:
- AFBR-2409Z: Receiver with SMA port
- AFBR-2419Z: Receiver with ST port
- AFBR-2419TZ: Receiver with threaded ST port
- AFBR-2419MZ: Receiver with metal ST port
Samples and production quantities of the AFBR-24x9xZ industrial fibre receivers are available now through Avago's direct sales channel and worldwide distribution partners. Further information on Avago fibre optics is available online at www.avagotech.com/pof.
