• High thermal stability
• High op cal coupling efficiency to mul mode fiber
• Industrial temperature range
• 55 MHz Bandwidth
Description:
The OPF340 series fiber op c transmi ers are high performance devices packaged for data communica on links. This
transmi er is an 850 nm GaAlAs LED and is specifically designed to efficiently launch op cal power into fibers ranging in size
from 50/125µm up to 200/300µm diameter fiber. Mul ple power ranges with upper and lower limits are offered which
allows the designer to select a device best suited for the applica on.
This product’s combina on of features including high speed and efficient coupled power makes it an ideal transmi er for
integra on into all types of data communica ons equipment.
Applications:
• Industrial Ethernet equipment
• Copper-to-fiber media conversion
• Intra-system fiber op c links
• Video surveillance systems
