What is the most important thing to be respected in fiber cable?

During each of the fiber optic cable installation project, we must bear in mind two very important things: First, it is never too bend the fiber cable above the minimum radius of curvature. Second, never pull the cord above the manufacturer-specific cable pulling tension.

Fiber Optic Cable Repairing Method

Fiber optics can repaired by several methods. Splicing allows two fiber optic cables to be joined together. Splicing enables the joining of broken cables or two different types of cables, The process is done with fusion splicing or mechanical splicing.

Fusion Splicing

Fusion splicing joins two cable optic lengths together with electric arc welding. Fusion splices generally cost from $0.50 to $1.50 each (as of 2011). However the splicing machine costs from $15,000 to $50,000 depending upon the level of accuracy required.
Mechanical Splicing

Mechanical splicing is done with a device that fits between two cables being spliced and aligns the fiber ends. Mechanical splices cost between $12 and $50 each. However, the initial investment is $1,000 to $2,000. The choice of the method can be based upon precision. Fusion splicing provides lower feedback reflection and less loss of signal. Some companies use each method depending upon whether precision digital signals are being sent or less precise analog signals.

Patch Cable

In most cases, there will not be sufficient slack in a broken cable to allow splicing without additional cable. After determining that a patch cable will work in the system, a temporary length of cable can be mechanically spliced and laid on the ground if temperatures do not fall below freezing. Outdoor repairs should be done in a temporary shelter, such as a tent, if possible, to protect the work from the elements.

What Is the Difference Between Ethernet & Patch Cables?

Ethernet Is a Protocol

While eight-conductor Ethernet cables with RJ-45 plugs are extremely common (these are the cables that look like over-sized phone cords), Ethernet itself is a protocol standard that defines the way that bits of information travel over a particular medium. The two most common cabled versions of Ethernet are traditional copper cables and fiber-optic cables.

Patch Cables

Most standard copper Ethernet cables are referred to as patch cables. However, ordinary phone cords can be considered patch cables, as well as the RCA and HDMI cables that connect a home TV and stereo system together.


Different Ethernet cables have different names, with “patch cables” being the most common. Some of the differences include the length of the cable as well as the purpose. For example, an Ethernet connection that is designed for speed and/or great distance can be referred to as a “backbone” or “long haul,” even though it may use the exact same type of copper cable that a patch cable uses.
