Fea ures
Electrically isolated plastic cap
package
High radiant output for fiber optic
applications
High speed
Designed to self align in the 0.228
inch diameter bore of standard fiber
optic receptacles. Press fit simplifies
component installation.
De scrip ion
The OPF370 series LED provides fiber
optic users with high coupled power and
wide bandwidth in a low cost package.
The LED’s are designed to interface with
multimode optical fibers from 50/125 to
200/300 microns.
