Structured Cabling: Backbone Cabling vs Horizontal Cabling

Image
Computer networks require complicated and specific cabling, particularly in business or academic settings. The cables used in cabling the networks must be made from certain materials. Backbone cabling and horizontal cabling are two main cabling methods used in today’s structured cabling system and neither is dispensable. Since backbone cabling and horizontal cabling have many differences, cables used these two structured cabling systems are also different from each other. Backbone cabling vs horizontal cabling: what’s the difference between them? What kind of cables are suitable for backbone cabling and horizontal cabling? The knowledge will be introduced in this article. Structured Cabling System Basics To understand backbone cabling and horizontal cabling, let’s understand the five subsystems of structured cabling firstly. These five subsystems are often found throughout a building and are connected together so that various types of data can be transmitted consistently and securely

How to Identify the Fiber Color Code?

  We have been using different types of   fiber optic cable   in labs and data centers for years. It is not unusual for a green hand to mix up the 50/125 and 62.5/125 multimode fibers, or the single mode fibers, not to mention the multi-fiber cables that may consist of tens and hundreds of fibers. Fortunately, there are systems made to address these issues, such as the EIA/TIA-598, which is the most recognized system worldwide. It includes fiber color code for different types and numbers of optical fiber cables. These fiber optic cable color codes help us to identify an optical fiber cable from its jacket, buffer, tube, connector, etc. Figure 1: Colored jackets of multi-fiber cable. Outer Jacket Color Code Colored outer jackets or print may be used on outside plant and premises fiber cables , e.g., fiber distribution cables, fiber optic patch cords, etc. In EIA/TIA-598, the fiber color code defines the jacket color codes for different fiber types. So for optical fiber cable that contai
