Fiber Optic Splice Closure

Posted July 3, 2008 * Comments(0)

Fiber-optic communication is a method of transmitting information from one place to another by sending light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, the use of optical fiber has largely replaced copper wire communications in core networks in the developed world.

After ten years development, ZhanTong has possessed 6 series more than 500 models Fiber Optic Splice Closure and 8 models termination box so far, and has got 16 national product patent which had been registered in different countries subsequently. Innovation and specialized in FOSC made Zhantong became No.1 manufacturer in product series and patent in the world.

After a period of intensive research from 1975 to 1980, the first commercial fiber-optic communication system was developed, which operated at a wavelength around 0.8 µm and used GaAs semiconductor lasers. This first generation system operated at a bit rate of 45 Mbit/s with repeater spacing of up to 10 km.

The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal using a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, and receiving the optical signal and converting it into an electrical signal.

Optical cable jointing is one of the most important parts of the fiber optic telecommunication line installation. For practical applications it is interesting to use some universal material kit for the sealing of the fiber optic closure ports with various cables, differing by their types and manufactures, in addition to basic closure kit

Fiber Optic Splice Closures manufactured by Zhantong Telecom has a lot of outstanding features, such as reasonable structure, high quality material based on advanced formula, reliable and long-lasting sealing and good resealing performance for reuses, easy installing. The expert’s conclusion to our splice closure from National Scientific and Technical Committee is that the structure, technique, technical indicators and performance of the product keep ahead in China FOSC field and reach advanced international standard.

The need for reliable long-distance communication systems has existed since antiquity. Over time, the sophistication of these systems has gradually improved, from smoke signals to telegraphs and finally to the first coaxial cable, put into service in 1940. As these communication systems improved, certain fundamental limitations presented themselves. Electrical systems were limited by their small repeater spacing (the distance a signal can propagate before attenuation requires the signal to be amplified), and the bit rate of microwave systems was limited by their carrier frequency. In the second half of the twentieth century, it was realized that an optical carrier of information would have a significant advantage over the existing electrical and microwave carrier signals.

On 22 April, 1977, General Telephone and Electronics sent the first live telephone traffic through fiber optics, at 6 Mbit/s, in Long Beach, California.

In 1966 Kao and Hockham proposed optical fibres at STC Laboratories (STL), Harlow, when they showed that the losses of 1000 db/km in existing glass (compared to 5-10 db/km in coaxial cable) was due to contaminants, which could potentially be removed.[1]

ZhanTong is a famous brand in the fiber industry for its products quality, complete product series and quick response to customers. Precision, innovative and customer focus, these three guiding principles govern the quality of the products we provide, and are key to the trust we have built up with our customers domestic and abroad over the years.

The development of lasers in the 1960s solved the first problem of a light source, further development of high-quality optical fiber was needed as a solution to the second. Optical fiber was finally developed in 1970 by Corning Glass Works with attenuation low enough for communication purposes (about 20dB/km), and at the same time GaAs semiconductor lasers were developed that were compact and therefore suitable for fiber-optic communication systems.
