![]() ![]() SC (subscriber or standard) connectors are larger and less expensive than LC connectors. They've become the standard for SFP modules and most modern network electronics.Ĭommon applications: networking, SFP modules, AV over fiber extenders, high-density connection applications ![]() LC (Lucent) connectors are one of the smallest formats of connector. ![]() View step-by-step connector termination videos. The below guide explores the connectors commonly used in audio-visual, networking, broadcast and other low-voltage applications. For example, 24 strand groups are with the fiber color code repeating with some variation, e.g., the 1st group of 12 strands are solid colors and the 2nd group is a solid color with a stripe or some other identifying marks.Fiber optic connectors are available in a variety of formats depending on the cable type and connection style. Each group of 12 fibers is identified with some other means. For cables that consist of more than 12 strands, the fiber optic cable color code repeats itself. There are two situations for multi-fiber cables: For cables that consist of multiple buffer tubes each with 12 or less strands, each tube will be numbered or colored following the same fiber color code, e.g., 1st tube is blue, 2nd is orange, etc. According to EIA/TIA-598, inner fibers are color coded in a group of 12 fibers and they are counted in a clockwise direction.įigure 2: Counting direction of a group of 12 fibers. ![]() They are often distinguished from one another by color-coded jackets, buffers or tubes on each fiber. Inside a multi-fiber cable, individual fibers are compliant to fiber color code as well. Inner Cable Organizational Fiber Color Code Such colors should be agreed upon between manufacturer and user. So for optical fiber cable that contains only one type of fiber we can easily identify it by its jacket color unless otherwise specified, the outer jacket of premises cable containing more than one fiber type shall use a printed legend to identify the quantities and types of fibers within the cable, for example “12 Fiber 8 x 50/125, 4 x 62.5/125.” Here are the jacket color codes for different fiber types:īesides the jacket colors specified in fiber color code standard, other colors may also be used if the print on the outer jacket can tell the fiber classifications. In EIA/TIA-598, the fiber color code defines the jacket color codes for different fiber types. Outer Jacket Color CodeĬolored outer jackets or print may be used on outside plant and premises fiber cables, e.g., fiber distribution cables, fiber optic patch cords, etc. These fiber optic cable color codes help us to identify an optical fiber cable from its jacket, buffer, tube, connector, etc.įigure 1: Colored jackets of multi-fiber cable. It includes fiber color code for different types and numbers of optical fiber cables. Fortunately, there are systems made to address these issues, such as the EIA/TIA-598, which is the most recognized system worldwide. 5/125 multimode fibers, or the single mode fibers, not to mention the multi-fiber cables that may consist of tens and hundreds of fibers. It is not unusual for a green hand to mix up the 50/125 and 62. We have been using different types of fiber optic cable in labs and data centers for years. ![]()
