Undercarpet cable,as this name implies, is run across a floor under carpeting. It is frequently found in open-space office or work areas that are defined by movable walls, partitions. A key feature of this cable is its ability to be rearranged or reconfigured as space needs change. One problem, however, is making turns without stressing the fibers. Unfortunately, the fiber on the outside of the turn must always take a longer path than the fiber on the inside. This unequal path length places differing stresses on the fibers.

The 3M Fibrlok 2540G fiber splice tool is designed to enable fast, easy splicing of 250-micron singlemode fiber in FTTP installations and in multimode enterprise installations. The Fibrlok 250um fiber splice is designed to be installed at the drop in fiber distribution terminals and optical network terminals outside and at fiber distribution units and wall outlets indoors. According to the company, the low-loss splice provided by the tool can be installed with little or no training by nonspecialized technicians working inside buildings or outdoors. With the tool, several crews can be equipped for less than the cost of a single

Optical fibers suffer from macro-bending loss at bends or curves on their paths. This is due to the energy in the evanescent field at the bend exceeding the velocity of light in the cladding and hence the guidance mechanism is inhibited, which causes light energy to be radiated from the fiber. This is shown in the following illustration. The part of mode which is on the outside of the bend is required to travel faster than that on the inside so that a wavefront perpendicular to the direction of propagation is maintained. So part of the mode in the cladding

In order to accurately calculate fiber optic link budget, you should know two concepts: installation loss and AC losses. What are installation losses? Installation loss is also called DC loss. It refers to optical losses caused by fiber optic cabling plant. This includes fiber transmission loss, attenuation versus wavelength and connector and splicing loss. Transmission Loss Transmission loss is the most important property of an optical fiber. Transmission loss is caused by material obsorption and linear and nonlinear scattering of light from impurities in the fiber. Macrobending and microbending are two more mechanisms for attenuation increase. Typical losses for single

Media converters are passive devices which provides networking flexibility with a minimum cost. Media converters make it easy to integrate new equipment into your structured fiber optic cabling network. The applications of media converters include: Extend the life of existing copper based equipment and network Extend the distance of an existing network Integrate data and telecommunication networks over fiber   Media Converter Applications   Extending the distance between a network switch and a file server or between two switches Media converters can be used to extend the distance between a network switch and a file server up to 2000 meters.
