How to deal with optical fiber transmission attenuation effectively

In the modern communication industry, communications, optical fiber transmission technology as a kind of common information data transmission mode, since it has advantages of high efficiency and high transmission speed, communication quality, greatly satisfy the demand of modern social development, attaches great importance to by the communications industry. Communication optical fiber transmission technology, however, its biggest drawback is the problem of signal attenuation, the cause of signal attenuation are many, therefore, how to effectively prevent the communication optical fiber transmission signal attenuation, this problem has become very pay attention to the content of the communication industry. Next, this article in view of the paper discusses the causes of communication optical fiber transmission attenuation, and take relevant effective improvement measures.

Regarding optical fiber attenuation, we need to figure out the cause of its attenuation and treat it separately.

First, the treatment method of optical fiber continuity attenuation is as follows:

(1) In the installation engineering design, construction and daily maintenance of optical fibers, high-quality optical fibers should be selected and the same batch of optical fibers should be used as far as possible, in order to make the overall characteristics of optical fibers match with each other as far as possible to achieve the purpose of reducing the optical fiber diameter to the optical fiber welding attenuation.

(2) The selection of experienced construction personnel for optical cable connection and comprehensive testing, the technical level of the construction personnel directly affects the amount of continuity attenuation, construction personnel should be strictly in accordance with the welding process of optical fiber connection, strict control of the joint may cause attenuation, and then eliminate the impact of human factors on the attenuation.

(3) The preparation of a relatively perfect optical fiber cross-section, the preparation of optical fiber cross-section is the key to connecting optical fibers. Whether the preparation of fiber cross section is perfect or not directly determines the continuity attenuation of fiber. The cross section of the optical fiber should be kept flat, without defects, and kept clean to avoid dust contaminating the optical fiber end face.

Second, the treatment method to solve the non-continuous attenuation of optical fiber is as follows:

(1) In the process of engineering survey, design and construction, the best route and route laying method should be selected.

(2) Cultivate a group of high-quality construction teams to ensure reliable construction quality.

(3) In the whole process of design, construction and maintenance, actively adopt effective optical cable lines to strengthen the lightning protection, electric protection, corrosion protection and mechanical damage prevention of optical fibers.

(4) When laying the cable, do not let the cable distort. The speed of deployment should not be too fast and should not exceed the length of deployment required by the specification. Be careful and take necessary protective measures at bends where the cable may be damaged.

(5) Strengthen the daily maintenance and technical repair work of optical cable lines. Optical fiber into the home is the inevitable result of the development of the information age. With the country's large number of construction and safe operation of all kinds of optical fiber communication networks, facing and solving the transmission attenuation problem caused by the use of optical fiber will greatly improve and optimize the transmission performance of optical fiber communication networks in the design, construction and maintenance of optical fiber communication engineering.
