Bifurcated Optical Fiber Assemblies
Ocean Optics’ bifurcated fiber optic assemblies easily connect to oxygen sensors, light sources, and
miniature fiber optic spectrometers via SMA terminations and an additional splice bushing. These single-
strand, multi-mode optical fibers are silica-core and silica-clad. Standard assemblies are 2 meters in
length, although custom fibers can be greater than 2 meters. The ends of the fibers are cleaved, epoxied
into the connectors, and polished.
Bifurcated assemblies are shaped like a "Y" with a stainless steel breakout located midway from the ends
of the fibers. The common end (the tail of the "Y") of a bifurcated assembly has two fibers side by side.
The common end of a bifurcated fiber can be coupled to a larger diameter probe with a splice bushing.
Bifurcated fibers used in Fiber Optic Sensors System include the following:
Bifurcated Fiber Description
