Providing design engineers with a trio of thermally stable optical coupling devices, TT electronics Optek Technology has developed a series of fiber-optic LED transmitters for integration into data communications equipment. Designated the OPF670 series, the LED transmitter family consists of the OPF670 in a TO-46 package, the OPF672 in a standard-profile metal housing and the OPF673 in a low-profile metal housing.

According to Dave Birtalan, VP of Optek Technology's components business unit, the high performance fiber-optic LED transmitters were specifically designed to efficiently launch optical power into 50/125?m- or 62.5/125?m-diameter multimode fibers.

"The devices in this series offer three power ranges with both upper and lower limits, allowing customers to choose the transmitter best suited for their specific application," said Birtalan. "The transmitters, which feature high coupling efficiency and thermal stability, are ideal for integration into data communications equipment."

All devices in the OPF670 series consist of an 850nm GaAlAs LED. Designed for active alignment into a connector receptacle, the OPF670 device is offered in a low-cost TO-46 package with a plastic lens cap.

The OPF672 and OPF673 transmitters are packaged in standard- and low-profile metal housing, respectively, and are equipped with an ST connector.

Pricing for the OPF670 series fiber-optic LED transmitters ranges from $5.75 to $12.25 in quantities of 1,000. Lead time, if stock is not available, is from six to eight weeks.
