Splice Bushings, Bulkhead Fittings
Splice bushings are used to couple two SMA-terminated fibers together. Simply screw each fiber into the
splice bushing finger-tight. Bulkhead fittings are used to fixture a fiber onto a panel. Install the bulkhead by
drilling a hole in the wall where you wish to mount the fiber. Fasten with the lock washer and nut provided.
Optical Fiber Color Codes
All Ocean Optics optical fibers are color-coded for simple identification. There are two color bands on one
end of the fiber. The color band nearest the termination identifies the fiber type (i.e., its wavelength
optimization), and is either white (UV/VIS) or black (VIS/NIR). The second color band identifies the
diameter of the fiber, and is one of several different colors. Use the table below as a handy reference.
