  • One kilometer of fiber-optic homes encountered a problem: the property charged a high “entry fee”

    At present, the broadband speed-up operation carried out by operators is mainly to replace the previous copper transmission cables with faster and more stable optical fiber transmission. According to the reporter of "Daily Economic News", at present, broadband operators have basically completed the transformation of urban areas and installed optical fibers at the doorsteps of residential areas, but encountered many difficulties in the "last one kilometer"

  • A brief history of fiber optic communication

    In 1841, two scientists, Daniel Colladon and Jacques Babinet, performed a simple experiment: drilling a hole in a wooden bucket filled with water, and then using a lamp to illuminate the water from above the bucket. The results surprised the audience. People saw that the shining water flowed out of the small holes in the bucket, and the water flow was curved.

  • Analysis of the difference between communication cables and optical cables

    Cable: When the phone converts the acoustic signal into an electric signal and transmits it to the switch via the line, the switch then transmits the electric signal directly to the other phone to answer. The line transmitted during this call is a cable. Inside the cable are mainly copper core wires. The core wire diameter is divided into 0.32mm, 0.4mm, and 0.5mm. The larger the diameter, the stronger the communication capability;

  • Development trend of micro optical cables

    Communication optical cables In recent years, the industry has been focusing on reducing the footprint of fiber optic networks. It can be said that with the development of small bend radius (RBR) fibers by fiber suppliers around 2005, the trend towards smaller cables and hardware has begun to emerge. Soon after these new optical waveguide designs appeared, an international standard was developed to regulate them, namely ITUG6

  • Communication optical cable manufacturers introduce the method of identifying the advantages and disadvantages of optical cables

    Communication optical cable manufacturers introduce the method of identifying the advantages and disadvantages of optical cables: fiber paste: fiber paste in outdoor cables can prevent the fiber from oxidizing. Because water vapor enters the tide, there is very little fiber paste used in low-quality fiber, which seriously affects the life of the fiber. Aramid: Also known as Kevlar, it is a high-strength chemical fiber. It is currently used most in the military industry.

  • The role of communication optical cables

    Communication optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fiber (thin glass fiber as hair) and plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable.

  • Broad prospects for China's wire and cable market

    Wires and cables are used to transmit electrical (magnetic) energy, information and wire products for electromagnetic energy conversion. Broadly defined wires and cables are also referred to as cables. A narrow cable is an insulated cable. It can be defined as: an assembly composed of the following parts: one or more insulated wire cores, and a covering layer, a total protective layer and an outer protective layer that each of them may have. Cables can also have additional uninsulated

  • Advantages of recycling fiber optic cable transmission?

    1. Multi-mode fiber transmission can be transmitted within 2 kilometers, single-mode transmission can be dozens to 100 kilometers without interruption, and ordinary copper wires (data lines) are only within 100 meters. At present, practical optical fibers are made of quartz (SiO2) with high purity, and the attenuation can be reduced to 0.2 near the wavelength of 1550nm.
