(typically the 16 mbd required by sercos is possible as well but please contact avago regarding the plan for the 16 mbd device.) profibus profibus, an acronym of pro cess fi eld bus , is an open fieldbus standard defined for data rates ranging from 9.6 kbd to 12 mbd in selectable steps for wire and optical fiber. profibus is a german national din 19245 standard and a european cenelec standard en 50170. the st connector is the recommended optical port of the profibus optical fiber version but other connectors are allowed as well. the hfbr-1515bz and hfbr-2515bz comply fully to the technical guideline using plastic optical fiber up to 6 mbd, and have a guaranteed performance at data rates up to 10 mbd. (typically the 12 mbd is possible as well, but please contact avago regarding the plan for the 12 mbd device.) interbus-s interbus-s, a special open sensor/actuator bus, is finding a broad acceptance in the factory automation industry. the hfbr-1505cz and hfbr- 2505cz were specially designed for this application and can be used with 1 mm pof and 200 m hcs fiber at the specified data rates of 500 kbd and 2 mbd. the optical transmission guideline is a supplement of the german national din e 19258 standard draft. on the european level, pren 50254 is the draft of the interbus-s fieldbus.

3 hfbr-15x5xz transmitters the hfbr-15x5xz transmitter incorporates a 650 nm led in a light gray nonconductive plastic housing. the high light output power enables the use of both plastic optical fiber (pof) and hard clad silica (hcs ). this transmitter can be operated up to 10 mbd using a simple driver circuit. the hfbr-1505xz is compatible with sma connectors, while the hfbr-1515xz mates with st connectors. eye safety: the hfbr-15x5xz is a class 1 led product and eye safe when used within the data sheet limits and under normal opera ting conditions. this includes all reasonably foreseeable single fault conditions per iec60825-1 and amendments. electrical/optical characteristics 0 c to +70 c unless otherwise noted parameter symbol min. typ.
