Modules deliver reliable data transmission in extended industrial temperature range
1 min read
Avago Technologies has unveiled a new line of optical fibre transmitters and receivers optimised for harsh temperature environments at electronica 2010.
The HFBR-152xETZ/252xETZ optical fibre modules are designed to provide reliable data transmissions over plastic or silica fibre in the –40 to 85°C extended industrial temperature range. The devices can be used to implement system control or drives in wind turbines and solar farms, traction inverters in trains, and for other industrial applications and medical systems.
According to Avago, the new modules eliminate the electromagnetic interference, crosstalk, and electrical ground problems that are common with copper wire solutions, while providing more flexible installation. The transmitters are based on a high power, 650nm LED, while the transmitters operate at speeds from 1-125MBd over distances up to 100metres.
The receivers contain a PIN photodiode and internal transimpedance amplifier. The modules come in plastic housing that interlock for single channel or duplex links in a horizontal mount configuration, developed to provide flexibility to designers during pcb layout.
