Avago Unveils Fiber Optic Links for Harsh Temperatures
The robust versatile modules are based on a high-power 650-nm LED and deliver reliable data transmission suited to many industrial applications.
Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, has revealed a new line of optical fiber transmitters and receivers optimized for harsh temperature environments, at the Electronica 2010 trade fair.
The HFBR-152xETZ/252xETZ optical fiber modules provide reliable data transmissions over cost-effective plastic or silica fiber in the –40 to +85° C extended industrial temperature range. Designers can use the devices to implement system control or drives in wind turbines and solar farms, traction inverters in trains, and for other industrial applications and medical systems.
An extension of the Avago Versatile Link series, the new modules eliminate the electromagnetic interference, crosstalk, and electrical ground problems that are common with copper wire solutions, while also providing easier, more flexible installation.
The HFBR-152xETZ transmitters are based on a high-power, 650-nm LED that is easy to drive and modulate. The transmitters operate at speeds from 1-125 MBd over distances up to 100 meters. The HFBR-252xETZ high-bandwidth 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, providing flexibility to designers during PCB layout.
“The addition of these new Versatile Link series modules with extended temperature range operation is based directly on requests from our customers in the rapidly growing renewable energy and transportation markets,” said Mickael Marie, marketing manager for industrial fiber products at Avago.
“With best-in-class electromagnetic compatibility performance and ease-of-use, Avago optical fiber modules have become the de-facto industry-standard for industrial applications.”
Avago is exhibiting the HFBR-152xETZ/252xETZ modules along with a wide range of its isolation, fiber optics, motion control and LED products for the industrial and automotive markets at Electronica 2010 in Hall A4 booth #458 at the New Munich Trade Fair Centre from November 9-12.
TheHFBR-152xETZ/252xETZ is compatible with 1-mm diameter plastic optical fiber and 200 μm hard-clad silica fiber and is RoHS-compliant. Transmitter and receiver application circuit schematics and recommended board layouts are available.
The HFBR-1527ETZ transmitter and HFBR-2526ETZ analog receiver are designed for transmissions from 1 to 125 MBd. The HFBR-1521ETZ transmitter and HFBR-2521ETZ digital receiver transmit from DC to 5 MBd, and the HFBR-1522ETZ transmitter and HFBR-2522ETZ digital receiver transmit from DC to 1 MBd.
Pricing for the HFBR-1521ETZ transmitter begins at $5.06 each in 200 piece quantities, and the HFBR-2521ETZ receiver also begins at $5.06 each in 200 piece quantities. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.
Avago Technologies is a leading supplier of analog interface components for communications, industrial and consumer applications. By leveraging its core competencies in III-V compound and silicon semiconductor design and processing, the company provides an extensive range of analog, mixed signal and optoelectronics components and subsystems to approximately 40,000 end customers.
