Splitter Branching Fiber-optic Patch Cords
The Splitter Branching Fiber-optic Patch Cord evenly splits the light from a large core diameter connectorized optical fiber into 2 or more branches of smaller core diameter connectorized optical fibers. A 15 cm long large core optical fiber helps obtain uniform distribution of light before a launch into 2 or more optical fibers bundled inside the central tubing. A 2-branch Splitter Branching Fiber-optic Patch Cord typically outputs around 16 % of the input power.
These patch cords are typically used in optogenetics for sharing powerful laser or LED light sources between several fibers and conserving uniform light intensity (mW/mm2) among their outputs.
The standard Splitter Branching Fiber-optic Patch cords has 2 branches, more are available if requested. A 2-branch patch cord splitter typically outputs around 16 % of the power entering the input optical connector, with variations depending on fiber type and the area recovery ratio.

This approach uses a 50 mm long metal tube with a 6.35 mm diameter to protect the passage from 1 to several fibers. The length of patch-cord from the metal tube to the patch-cord split, called the central jacket, can be protected using a different jacket type. Splitter patch cords are not suitable for short cables less than 30 cm long. This version allows improved splitting of laser light over older models. In all other applications, the Splitter Branching Patch Cords maintain the same high-quality performance as our legacy Standard Branching Patch Cords.
• Minimum total cable length is 35 cm.
• The Type-A (AX identifier) patch cords have no central jacket, with the splitter starting at the metal tube. The split is done 17.5 cm from the input.
• The Type-B (BX identifier) patch cords have a central jacket covering the length between the metal tube and the splitter. The split is done at 15 cm from the output.
• Not recommended for high power application.
The maximum input power tested in continuous is 100 mW for wavelength between 450 and 650 nm. Please ask our technical support to use with higher power or different wavelength range.
