  • How to identify a fiber optic cable connector from an image

    How to identify a fiber optic cable connector from an image

    The big silver connector at the bottom of the photo at the right is the Deutsch 1000, what was probably the first commercially successful fiber optic connector. It was really a "pin vise" holding a stripped fiber. Most fiber optic connectors are plugs or so-called male connectors with a protruding ferrule that holds the fibers and aligns fibers for mating. This listing can help distinguish between the various types of data connectors you may encounter when working with data and communication. Identifying optical connectors by their physical characteristics is one of the quickest ways to determine their type. By adopting the TIA/EIA‑598C standard, you gain a universal “language” of colors that speeds identification, reduces miswiring, and enhances safety. Fiber color code is a color coding system used in fiber optics as specified by the TIA-598 standard to identify cables, connectors, and individual fibers.
