![]() It consists of a core made of glass or plastic that is surrounded by layers of protective material, such as cladding. They combine an optical fiber cable and transceivers, eliminating the connector entirely.Ī fiber optic cable is a type of cable that uses light to transmit data over long distances. If you are selecting cable for a 40GbE or 100GbE application, consider Active Optical Cables (AOCs). For example, if your 10G Ethernet switch has multi-fiber MTP ports, you'll need cables with the required number of fibers. In addition to fire rating, other cable jacket properties such as flexibility and strength under tensile load should be considered.įor more information on jacket materials and fire ratings, see Fiber Optic Cable Jackets.įiber optic cable terminations are typically dictated by the ports on your network equipment. It is multimode-only and field-terminated-only by pre-polished/splice method. It uses pins for alignment and has male and female versions. If your cable will run through risers or plenum spaces, make sure the cable jacket is rated accordingly. MT-RJ is a duplex connector with both fibers in a single polymer ferrule. In the US, fire rating and jacket identification is defined by Article 77 of the National Electric Code (NEC). Refer to Table 2: Fiber Optic Cable Speeds and Lengths for guidance.Īll indoor fiber cabling must meet local fire codes. Note that MMF range depends on the OM rating of the cable. If data transmission speed or distance are key requirements, consider SMF. If you need to move a large amount of data over a relatively short distance (for example, less than 300 meters), OM3 MMF might be the best choice. multimode, focus on the connection distance and network speed dictated by the overall network design. For example, the price of a 3 meter LC-to-LC duplex SMF cable is about one US dollar more than the equivalent MMF cable. Nowadays, the cost difference is not so significant. Multimode fiber (MMF) used to be the automatic choice for datacenters and corporate networks because it was less expensive than singlemode fiber (SMF). ![]() If you need assistance in determining requirements or selecting pre-terminated or custom fiber cable, please contact us. Additional requirements will be driven by the needs of your specific application. Once you have narrowed down your choices, you should also consider cost and future-proofing. Start by determining requirements for the following: ![]()
