Fiber Optic Transmitter
OPF670 Series
Features:
•
•
•
•
•
Low cost 850 nm LED technology
Low cost TO package with electrically isolated plastic cap
High thermal stability
High optical coupling efficiency to multimode fiber
Industrial temperature range
Description:
The
OPF670
series fiber optic transmitters are high performance devices packaged for data communication links.
These transmitters are an 850 nm GaAlAs LED and are specifically designed to efficiently launch optical power
into either 50/125µm or 62.5/125µm diameter multimode fiber. Three power ranges are offered, which allows the
designer to select a device best suited for the application.
The
OPF670
is offered a low cost TO package with a plastic lens cap. The device is designed to be active aligned
into a connector receptacle.
Applications:
•
•
•
•
Industrial Ethernet equipment
Copper-to-fiber media conversion
Intra-system fiber optic links
Video surveillance systems
