This article describes the fire resistance ratings code from NEC for fiber optic cables. We carry a large inventory of all types of fiber optic cables, you can get them here or by clicking on the following picture. :: Why Do We Need Fire Rating on Fiber Cables? The National Electrical Code (NEC) has classification system for optical fiber cables. These requirements specify how the fiber cables will perform under fire conditions. These requirements concentrate on how the fiber cables will add a dangerous amount of fuel and transmit fire from one place to another. Article 770 of the NEC,

This article describes the purpose of fiber fan out kit and breakout kit and how they are used in fiber cable installations. You can get fiber fan out kit products here and get fiber breakout kit here. Or click on the following pictures. Fiber Optic Fan Out Kit Fiber Optic Breakout Kit Where are Fan out Kit and Breakout Kit used? Fiber fan out kit is used to terminate large fiber counts fiber cables. Some fiber cables, such as simplex and duplex fiber cables, and breakout fiber cables, already have 3mm jacket to accept fiber connectors and can be terminated

Dispersion is the spreading out of a light pulse in time as it propagates down the fiber. Dispersion in optical fiber includes model dispersion, material dispersion and waveguide dispersion. Each type is discussed in detail below. Model Dispersion in Multimode Fibers Multimode fibers can guide many different light modes since they have much larger core size. This is shown as the 1st illustration in the picture above. Each mode enters the fiber at a different angle and thus travels at different paths in the fiber. Since each mode ray travels a different distance as it propagates, the ray arrive at

There are several important factors determine the optical fiber’s capability to collect light and transmit it along the fiber. These factors include optical fiber’s core size, its mode field diameter and its numerical aperture. What is optical fiber’s core size? Core size is the physical dimension of the fiber core. The core’s size has a big impact on coupling light into a fiber. The core’s size has to be at least as big as the light source in order to collect light efficiently. If the light source is larger than the fiber core, much of its power goes into the

This article describes the development of Ethernet networking over Plastic Optical Fiber (POF). You can get the plastic optical fiber here or by clicking on the following picture. The Benefits of Plastic Optical Fiber POF Plastic optical fiber has emerged as a low cost alternative to twisted pair copper cabling and coaxial cables in office, home and automotive networks. Why? POF has many benefits. POF is lightweight POF is robust POF is cheap POF is easy to install. You can cut POF with a sharp blade and no expensive and time-consuming polishing as with glass fibers Most important of all,
