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.
