Fiber Optic Cables Tutorial

What are Fiber Optic Cables?
You may hear about fiber optic cables whenever people talk about the telephone communication system, the cable TV system, the Ethernet, the Internet and even the medical imaging and mechanical engineering inspection. Optical fibers are strands of optically pure glass as thin as a human’s hair that carry digital information over long distances. A fiber optic cable is a cable containing one or more optical fibers and the cladding, buffer coating, Kevlar strength members and a protective outer jacket. We used them sending infomation by light pulses signals and satisfy the higher speed we needed in the medias or communications. In addition, there are another fiber optic cables which called sensing fiber optic cables. This type of fiber optic cables are widely used in Petrochemical, Steel, Mine for fire detecting, bulding health detecting, temperature detectingation.

How are Fiber Optic Cables used?
Fiber optic cables as an important component of the signal transformation. They are always plugged into another communication equipment and patch panels to provide a physical connection to a network or device, transfer the signal types. What’s more, the sensing fiber optic cables are even installed to monitor the changes in environment, transportation or energy industries.

Where are Fiber Optic Cables used?
Fiber Optic Cables are throughout every corner of our lives. The direct users of fiber optic cables are the commercial business, governments, the military and many other industries for myriad applications involving the transmission of voice, video and data. As some small homework network, the use of fiber optic cables are more and more common.

Commonly Used Types of Fiber Connectors
In the signals transmission, fiber optic cables are always connect with some quipment using some connectors. we can see the commonly used typed of fiber connectors in the following tables:

Fiber Optic Cables & Sensing Fiber Optic Cables
As the described above, the common use of Fiber Optic Cables is to sengding signals in the communication or media systems, such as FTTH Fiber Optic Cables, Indoor & Outdoor Cables etc. There are a lot of information about communication using fiber optic cables so that I am not wordy to describe so much in this article. In contrast, the sensing fiber optic cables are less information because it is a new technology and application of fiber optics. I am going to describe something about the sensing fiber optic cables in the following.

Sensing Fiber Optic Cable is a sensor based on optical fiber cable which is used because its more sensitive characteristic for some physical effects. Sensing Fiber Optic Cables are widely used in monitoring or measuring some changes of physical factors (like pressure vibrations, temperature changes, the transmission light intensity, phase, polarization, and other changes) in many field, such as oil & gas industry, energy, transportation, enviroment security and even the fire prevention.

Sensing Fiber Optic Cable in Fiberstore
There are 6 kinds of Sensing Fiber Optic Cables on sale in Fiberstore. Our sensing fiber optic cable with excellent mechanical performance makes it use as easy as a wire and adapt to various conditions.

PBT Tube Temperature Sensing Optical Cable

PBT-tube-gel-sensor-cableThe cable is consist of bare fiber, ointment, PBT imitation tubing, Kevlar and outer jacket which has a good performance of optic transmission, an excellent anti-electromagnet ability and resist water very well. It can be used for temperature and stress measurement, which is perfect for high voltage and electromagnetic area because of the nonmetallic structure.

Armored Temperature Detecting Sensor Cable

Armored Temperature Detecting Sensor CableIt is strengthened by both SUS spring tube and SUS braiding and has very good mechanical performance of tensile resistance and pressure resistance. The cable is widely used in fire detecting, building health detecting, temperature detecting, etc.

Silica Gel Sensing Fiber Optical Cable

Silica Gel Sensing Fiber Optical CableThe structure of cable is very simple, but the special Silicon jacket and Teflon tube ensure a very good performance of high temperature resistant and high voltage resistant so that it is very suitable for high temperature resistant and high voltage environment, it could work normally even in the 250 ℃ high temperature environment or 6kv high voltage environment.

Teflon Sheathed sensor cable

Teflon Sheathed sensor cableThe Teflon cable is very suitable for high temperature resistant environment, it could work normally even in the 150 ℃ environment. And it could be used for fiber temperature sensing system.

Seamless Tube Temperature Sensing Optical Cable

Seamless Tube Temperature Sensing Optical CableThe cable is make up of bare fiber, ointment, stainless steel seamless tube and sheath. Seamless tube can provide high tensile resistance and crush resistance. It is usually used in oil field, mine and chemical industry, for temperature and pressure inspection to avoid any accident.

Copper Braid Armored Sensor Cable

Copper Braid Armored Sensor CableCopper braid armored sensor cable could be used in outdoor optical fiber communication and optical fiber sensor. In power environment, the special cable structure could reduce the impact of electromagnetic wave and electromagnetic field, and make less optical signal loss.

China Formal Implementation for Fiber Optic Network Fiber To The Home Needs to be Improved

On April 1, the formal implementation of fiber optic network Fiber To The Home(FTTH) of the policy was put into effect, is the process of city informatization construction and renovation, but in the process of execution, some parts of the acceptance standard has yet to be improved.

MOHURD(Ministry of Housing and Urban-Rural Development) and MIIT(Ministry of Industry and Information) held a teleconference jointly that asked to implement the previous issued FTTH fiber optic cables documents, they are Residential area and residential buildings fiber-to-the-home communication facilities engineering design specifications.

It is worth mentioning that the specification is not only for new residential area, building, and it’s suitable for both residential, building renovation and expansion project of fiber optic transmission, that the fiber to the home faces the first national standards. At the same time, the  policy of the specific implementation, relevant statement to make clear, the user can choose the carrier freely.

In addition, in the process of optical fiber to the home project acceptance, the acceptance by the force of the strength and acceptance standards is also related to the implement of this policy, whether they are in good condition.

In fact, on July 15, 2010, our country had issued national standard of housing and urban-rural development of the residential area and residential buildings communication facilities specification “, “residential and residential building acceptance of communications engineering. Compared with the previous situation, the new “standard” in addition to the new requirement for optical fiber to the home, in the “mandatory norms” is made obviously improve.
