Link Subsystem cable required total number of pairs and total fiber count, should meet the actual needs of the project, and leave adequate backup capacity. Data applications can use the diagonal cable Category 5 cable, for the diagonal cable length should not exceed 90m. Phone applications can use three types of diagonal cables, if considered as a data backup cable can be used with a diagonal diagonal Category 5 cable. Vertical lines when using fiber optic cable, recommended 6-cell or 12-core cable, vertical lines should have 25% margin. A large number of diagonal cables on its core number from 25 pairs and 50 pairs, 100 pairs most commonly used as a support for voice transmission vertical trunk cable. Class 5 25 pairs of diagonal support high-speed data signal is transmitted to the 150m place. Note: Re-Route subsystems needed before determining the total number of cables, the signal must be aware of and agree to share the cable restrictions, sometimes using a small amount of four pairs of diagonal cables as a backup. For horizontal cable distribution frame switching hardware devices used in all plug-fast cross-connect hardware jumpers, voice trunk cable with Snap-jumpers. Optical fiber splicing and testing: 1. fusion: fiber splicing general contact outside the unit staff. Requires the use of a dedicated "fiber splicing machine" can be carried out, and the number of contacts. When the fiber splicing, the need to cable outer protective layer, armor and other optical fiber attachment stripping remove impurities, with pigtails slimming high temperature welding. And the use of heat-shrinkable tube packaging protection. And the line of the body and secured to the rules of the disc from the optical interface box, flange pigtail and the other end connected to the fiber interface box. 2. Testing after welding: fiber splicing is completed, can be tested by special equipment, general FECS construction site does not have the appropriate test equipment, then also for initial testing in two ways, namely transmittance test and power communication packet testing. Transmittance testing is, when the ends of a fiber are fusion is completed, a strong light source can be used in the optical fiber end of the irradiation, if under the weld is good, there is no damage to the optical fiber, the other end of the fiber to be can emit a strong beam of light. This method is mainly confirms the presence of broken fiber overall loss or impairment of the situation. Fiber: Fiber variety, roughly divided into single-mode multi-mode, armored unarmoured, 2/4/8-core single-mode fiber, etc: that at the operating wavelength, only one propagation mode transmission fiber, commonly referred to as single mode optical fiber SMF present, the cable and optical communications, is the most widely used fibers. Fiber core is very small (about 10pm) and a refractive index showed a step-like distribution SMF no multi-mode dispersion, large-mode fiber transmission band is wider. Just a bunch of light, the signal is relatively strong, can be applied to high-speed, long-distance applications, and they also chummy its costs are relatively higher. (2) Multi-mode fiber: as the fiber length from each other according to the working mode of its spread may be a plurality of modes of an optical fiber is called a multi-mode fiber core diameter of 50pm, the transmission mode up to a few hundred, compared with the SMF transmission bandwidth mainly dominated by the mode dispersion. In the short-distance communication field MMF still renewed attention. When the refractive index profile of MMF by classification, are: Gradient (GI) type and step (SI) type. GI type refractive index in the core center for the highest transmission capacity than the SI type large. Multi-mode fiber is more widely used in a short distance or a relative velocity less some areas, which uses LED as the light source, use of a wide wire, so the scattered larger; plus the entire fiber has a plurality of incident angles light, so the signal is not as good as single-mode fiber is good, but the relatively low price is its advantage.
