Structural Cabling - ISP / OSP
Structured Cabling is a 'standards' based method of engineering and installing an integrated data, voice and video cabling system for your business. The Structured Cabling infrastructure is the foundation on which all other technologies will run.
Documenting the testing process can save time and material in the installation and allow better planning for upgrading. After installation, the documentation can be completed with test data for acceptance by the end user. If equipment is repositioned on a network, as is always the case, proper documentation will allow easier rerouting to the proper end points. During troubleshooting, proper documentation is mandatory for tracing links and finding faults.
The documentation process for fiber optics, however, is different from that of most copper cable installations. Where a copper cable of CAT 3, 5 or 6 types is generally used to connect a single link, fiber optic cables-especially backbone cables-may contain many fibers connecting number of different link that may not even be going to the same place. Furthermore, copper cable may be tested only for continuity while loss data will be required for most fiber optic cable plants. The fiber optic cable plant, therefore, must be documented as to the path of every fiber, connection, and test.
Fusion splicing works on the principle that - an electric ARC ionizes the space between the prepared fibers to eliminate air and to heat the fibers to proper temperature .The fiber is then fed in as a semi liquid and melds into its mate.. The perfect fusion splice results in a single fiber rather than two fibers having been joined. One drawback to fusion splicing is that it most generally must be performed in a controlled environment, that is, a splicing van or trailer, and should not be done in open spaces because of dust and other contamination.
Mechanical splicing, on the other hand, is quick and easy for restoration, its major use, and is also used for new construction, especially with multi-mode fiber, it does not require a controlled environment other than common sense dust control. The strength of a mechanical splice is better than most connectors; however, fusion remains the strongest method of splicing.
