Frequently Asked Questions: Optical Fiber
OF1. What is the color code for fibers in fiber optic cable?
The identification scheme used in Corning Cable Systems Fiber Optic Cables is based on EIA/TIA-598, "Optical Fiber Cable Color Coding." EIA/TIA-598 defines
identification schemes for fibers, buffered fibers, fiber units, and groups of fiber units within outside plant and premises optical fiber cables. This standard allows for fiber units to be identified by means of a printed legend.
This method can be used for identification of fiber ribbons and fiber subunits. The legend will contain a corresponding printed numerical position number and/or color for use in identification.

OF2. Should fibers be cleaned after they are cleaved?
No. Fibers cleaned after cleaving will leave residue on the end-face of the connector. This will affect the performance of the fusion splicer.
