Description:
The OPF340 series fiber opc transmiers are high performance devices packaged for data communicaon links. This
transmier is an 850 nm GaAlAs LED and is specifically designed to efficiently launch opcal power into fibers ranging in size
from 50/125µm up to 200/300µm diameter fiber. Mulple power ranges with upper and lower limits are offered which
allows the designer to select a device best suited for the applicaon.
This product’s combinaon of features including high speed and efficient coupled power makes it an ideal transmier for
integraon into all types of data communicaons equipment.
Applications:
• Industrial Ethernet equipment
• Copper-to-fiber media conversion
• Intra-system fiber opc links
• Video surveillance systems
Features:
• Low Cost 850 nm LED technology
• Hermec metal can package
• High thermal stability
• High opcal coupling efficiency to mulmode fiber
• Industrial temperature range
• 55 MHz Bandwidth
