... Supplier Reference HCS is a registered trademark of OFS ® I. Introduction This application note discusses the functions and fea- tures of the 10 MBd HFBR-0508Z Fiber Optic Versatile Link, which is designed for a variety of industrial applica- tions. These include serial data interfaces in robots, ma- chine tools, assembly and printing machines, and gate- drive circuits in frequency inverters. Circuit design hints and other subjects not found in the product data sheet will also be presented. The reader can use this informa- ...

Interconnects without Crosstalk Fiber-optic technology is completely changing data communications, particularly in industrial environments, where data must be transferred between machines more quickly than ever before. Avago Technologies believes that fiber optics is replacing copper cabling in many of these applications because of the wide range of advan- tages inherent to fiber cable. Glass and plastic fibers, be- ing dielectric materials, are completely immune to stray electromagnetic fields, which are common in industrial applications that use motors and power switches. These fibers can be placed in a duct alongside high-voltage metal cables without being susceptible to crosstalk. This feature simplifies system installation. Twisted-pair cop- per cables require a minimum distance from power lines to guarantee error-free data transfer. 2. International EMC ...

Receiver Technology LEAD FRAME LENS The new HFBR-2528Z receiver with its TTL/CMOS-com- patible output is specified for data rates from DIE MBd NRZ (non-return to zero). It has a sensitivity of -2 dBm peak with mm POF sensitivity of -23 dBm peak with 200 HCS fiber. Propagation delay times t ® low to high) and t ...

... If the LED drive cir- cuit recommended in the HFBR-528Z data sheet is 5510-10 used, the transmitter cannot over-drive the HFBR-2528Z receiver even when the length of the fiber-optic cable is virtually zero meters. 6 ...

... R2. As temperature increases MINIMUM and LED forward voltage declines, the potential differ- ence across R2 increases and Ohm’s law dictates that the current through R2 and the HFBR-528Z will increase. This increase in the drive current partially equalizes the reduced light output due to the negative output-power temperature coefficient. The coupled power into mm POF and 200 µm HCS is specified for minimum and maximum values versus the ...

... Standard “off-the-shelf ” line drivers and receivers for RS- 422 and RS-485 bus and the TTL receiver output and transmitter input. While the majority of industrial communication appli- cations are specified for data rates of 2 MBd and below (much lower than the speed of the HFBR-0508Z link), the large dynamic range of the HFBR-2528Z receiver allows a fiber-optic link to be designed without transmitter op- tical output power adjustment. This factor makes the in- stallation instruction much simpler and avoids trouble- shooting exercises due to receiver overdrive conditions. Whether the link is anywhere from zero meters up to the maximum length specified in the data sheet or whether the fiber is HCS or POF, the link will work reliably the mo- ment that the power is turned on ...
