The Role of Optical Fiber in 5G Network

5G technology will bring us faster and more stable mobile network. With 5G technology, our mobile phones, tablets and other electronic devices can be connected to more devices at the same time, and there will be no jam. In addition, 5G technology can also be applied to self driving cars, intelligent instruments, health monitoring equipment, virtual reality equipment, etc. This will make a great change in human life. 

Like the early 2G, 3G and 4G mobile networks, 5G mobile networks are digital cellular networks. In this kind of network, the service area covered by the supplier is divided into many small geographical areas called cellular. Analog signals representing sound and image are digitized in mobile phones, converted by analog-to-digital converters and transmitted as bit streams. All 5G wireless devices in the cellular network communicate with the local antenna array and low-power automatic transceiver in the cellular network through radio waves. The transceiver allocates channels from the common frequency pool, which can be reused in geographically separated cellular networks. The local antenna is connected to the telephone network and the Internet via a high bandwidth fiber optic adaptor or wireless backhaul connection. As with existing mobile phones, when users cross from one cellular network to another, their mobile device will automatically switch to the antenna in the new cellular network.

5G will happen in the airy realm of radio waves. In order to achieve this goal, large telecom companies must make full use of the underused part of the spectrum, and in order to use the spectrum, it needs a lot of fiber optic patch cord to provide support. Telecom companies need a lot of new transmitters to get all the data to your phone, many of which will still be connected to the Internet via duplex patch cords. Fiber optic patch cable is like a very thin glass fiber, but it can transmit data.

To make this work, many fiber companies are being commissioned to produce millions of miles of new fiber optic cable patch cords, with two pairs of fibers twice as many, one for the uplink and one for the downlink. 

There are glass fibers in every sc to lc fiber patch cable, which are unspooled by a device called a payoff machine. These machines are huge. They're about 6 feet tall, 25 feet long and 4 feet wide. Different colors and codes let technicians know which fibers to splice when connecting two lc sc patch cables. Glass fibers are passed through weather resistant buffer tubes and wrapped in strong synthetic aramid yarns so that the st sc fiber patch cables can be protected. The final step in production is to use a black sheath made of durable polyethylene. A finished lc lc single mode fiber cable can be up to 30000 feet, or more than 5 miles.

In the world, these lc to lc multimode fiber cables may be covered on poles or hidden in shallow trenches beneath urban streets. Some cables will also be buried under the sea floor to connect networks in different areas. In these places, most of the sc to sc multimode fiber patch cables are invisible, and they may one day connect to your 5G device and constantly transfer data to your device.
