- Fiber To The X (FTTH, FTTC, FTTW, Etc.)

Fiber to the X or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. 

For example, today's users of mobile devices depend on wireless connections for their voice, data and even video communications. Even homes and businesses may depend on wireless, especially those who are not in urban or suburban areas served by FTTH (fiber to the home) or FTTC (fiber to the curb.) Some of us in the business now use the term FTTW for fiber to wireless, since wireless depends on fiber for the communications backbone and increasingly the connection to the wireless antennas, no matter what kinds of wireless we use.  


- The Importance of the Physical Layer

The success of 5G can be attributed to the use of massive multiple-input multiple-output (MIMO) technology in the microwave frequency band. Their main focus is on the physical layer of mobile networks, the hardware that transmits signals. Other layers of the communication system perform other functions such as delivering voice, video or data input into the system, converting these input signals into a format suitable for transmission, and multiplexing signals from different sources into a single data stream so that Transport layer over the physical network. 

Optics are part of the physical layer. Optical transmitters generate optical signals that propagate through fiber optics or air for free-space communications. Radio and microwave signals from the antenna travel wirelessly through the air. Electron transmitters generate an electrical current that travels short distances through wires. 

Fiber plays an important role in the physical layer of 5G mobile networks. They provide high-capacity backbone transport between global telecommunications systems and data centers. They also provide backhaul between regional distribution nodes and cell towers that distribute wireless signals at radio frequencies. Passive optical networks transmit radio signals in the 28 GHz band used by 5G networks to distribute high-frequency signals from local antenna transmissions to serve small "picocells."


- 5 Types of Fiber Cables for 5G Networks

At present, there are still some uncertainties in the selection of 5G network architecture and technical solutions. But at the basic physical layer, 5G optical cables must meet the needs of current applications and future development. 

The following are 5 types of fiber optic cables, which solve the problems in 5G network construction to a certain extent.

  • Bend Insensitive Optical Fiber for Easy 5G Indoor Micro Base Stations
  • OM5 Multimode Fiber Applied to 5G Core Networks
  • Micron Diameter Optical Fibers Enable Higher Fiber Density
  • ULL Fiber with Large Effective Area Can Extend 5G Link Length
  • Optical Fiber Cable for Faster 5G Network Installation
