HFBR-1505AZ/2505AZ (SMA Tx/Rx for SERCOS) HFBR-1515BZ/2515BZ (ST(R) Tx/Rx for PROFIBUS) HFBR-1505CZ/2505CZ (SMA Tx/Rx for INTERBUS-S) Fiber Optic Transmitters and Receivers for SERCOS, PROFIBUS and INTERBUS-S Applications Data Sheet Description Features SERCOS Meets industrial SERCOS, PROFIBUS, and INTERBUS-S standard SERCOS, an acronym for SErial Realtime COmmunications System, is a standard digital interface for communication in industrial CNC applications. SERCOS is a European (EN 61491) and international standard (IEC 61491). The optical interface allows data rates of 2, 4, 8, and 16 MBd and data transfer between numerical controls and drives via fiberoptic rings, with voltage isolation and noise immunity. The HFBR-1505AZ and HFBR-2505AZ products comply with SERCOS specifications for optical characteristics and connector style, and have guaranteed performance up to 10 MBd. (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 PROcess FIeld 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(R) 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.) SMA and ST(R) ports 650 nm wavelength technology Specified for use with 1 mm plastic optical fiber and 200 m hard clad silica Auto-insertable and wave solderable DC - 10 MBd data rate RoHS-compliant Applications Industrial control data links Factory automation data links Voltage isolation applications PLCs Motor drives Sensor, meter and actuator interfaces 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. ST(R) is a registered trademark of AT&T. HCS(R) is a registered trademark of OFS Corporation. Package Information All HFBR-X5X5XZ series transmitters and receivers are housed in a low-cost, dual-in-line package that is made of high strength, heat resistant, chemically resistant and UL 94 V-O (UL file # E121562) flame retardant plastic. The transmitters are easily identified by the light grey colored connector port. The receivers are easily identified by the dark grey colored connector port. The package is designed for auto-insertion and wave soldering so it is ideal for high volume production applications. Handling and Design Information When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is sufficient to remove particles of dirt; methanol on a cotton swab also works well. Recommended Chemicals for Cleaning/Degreasing X5X5X Products Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as 1,1,1 trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride or N-methylpyrolldone. Also, Avago does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. CAUTION: The small junction size inherent in the design of these components increases the components' susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD.
