What is optical fiber fusion splicing Optical fiber fusion splicing is a welded joint formed between two optical fibers

Fiber optic cables are exposed to electrical, mechanical, chemical and environmental elements, so proper installation is critical for the long-term stability and survival of fiber cables Cable installation must also meet the NEC(National Electric Code) and local building codes

The use of fiber optic systems is expanding at a amazing rate Only in the past 10 years, fiber optic communications systems have replaced almost all coaxial and twisted pair cables especially in network backbones

:: What is structured cabling Modern computer LAN (local area network) wiring has the concept of structured cabling

:: Choices of connectors Over the years, a large variety of fiber optic connectors have been designed for most fiber optic installations Lightwave equipment manufacturers have never standardized on any one connector type, they actually provide a selection of connectors for their equipment interface

:: The Definition of Backbone Cabling Backbone cabling may be within one building or between buildings on a campus All wiring between telecommunication rooms is called as backbone cabling

The two most common outdoor fiber optic cable installations are pole line aerial installation and underground cable installation Underground cable installation can be buried directly underground or placed into a buried duct

:: Duct/Innerduct materials and colors: Fiber ducts are usually made from HDPE (high-density polyethylene), PVC or other compound They are usually in black or gray

:: 1 What is the difference between copper cable and fiber optic cable

Just like copper cables, NEC (National Electrical Code) requires indoor fiber optic cables be marked with their fire and smoking ratings NEC requires all indoor fiber cables be marked correctly and installed properly for its intended use
