The Relationship Between Fiber-Optic Communication and 5G

(The 5G era is imminent.)
5G The importance of future applications
Staying connected has become an indispensable part of modern daily life. People have grown accustomed to making calls, sending emails, and watching videos anytime, anywhere. Looking ahead, human society will enter an era of even more advanced and faster network interconnectivity, where possibilities may far exceed our imagination. The industry’s demand for concurrent and ultra-low-latency connections will continue to rise.
5G The Necessity of Future Existence
Currently, 3G and 4G networks require a macro base station to be deployed every few miles, typically on tall towers or building rooftops. In macrocell networks, signal blockage often creates coverage gaps, necessitating the additional deployment of small cells to fill these gaps or enhance coverage for users.
The Relationship Between Fiber Optics and 5G
5G networks require a denser deployment of radio antennas to achieve massive connectivity, low latency, and high data rates. Although numerous variables may come into play, in some scenarios it may be necessary to deploy 5G small cells at intervals of 500 feet or less. By deploying more base stations within a smaller footprint, a denser, faster, and more highly connected fiber-optic communication network is created.

So, what happens as wireless networks become increasingly dense? In short, wireless networks are undergoing “fiberization”—that is, the integration of more fiber optic infrastructure. The resulting advanced fiber-optic communication networks enable fiber to extend even deeper into cities and communities, reaching street-level infrastructure and building facades.

Semiconductor lasers offer numerous advantages: electrons are directly converted into photons, resulting in an electro-optical conversion efficiency of over 50%, which is significantly higher than that of other laser types; their operational lifespan exceeds 100,000 hours, far surpassing that of other lasers; semiconductor lasers can also be modulated in output—something other laser types cannot achieve; moreover, they are compact, lightweight, and cost-effective, with semiconductors being considerably cheaper than materials such as ruby.
In fact, understanding the advantages of semiconductor lasers is not difficult. Although most people may not realize it, everyone has seen LED (light-emitting diode) lamps. The principle behind LED emission is that when charge carriers recombine at the PN junction, the excess energy is released in the form of light—electric current is directly converted into light, rather than having to heat a filament as in an incandescent bulb. Consequently, LEDs offer a host of advantages over traditional bulbs, such as a wide range of colors, adjustable luminous intensity, long service life, and low cost—much like the advantages of semiconductor lasers mentioned earlier. A semiconductor laser can be thought of as taking the basic principle of LED emission and adding the amplifying effect of an optical resonant cavity; moreover, this resonant cavity does not need to be built separately—it already exists within the semiconductor material itself.
The laser is a rare example of a technology that became immediately practical upon its invention; as early as 1961, it was already being used in surgery. This is because the laser’s unique properties are exceptionally pronounced: its photons are highly coherent, all traveling in a single direction, and its energy is concentrated at a single point—enabling it to outshine the Sun by a factor of over a million. With a sufficiently powerful laser, one can precisely target any material for cutting, machining, or other processing tasks. Lasers find extensive applications in cutting, welding, measurement, marking, and many other areas, and are now employed across countless industries—including communications, industrial manufacturing, healthcare, and cosmetics—continuously replacing traditional processes.
