Fiber Optic is a type of cable made of glass

By Steve Rogers,
Fiber Optic is a type of cable made of glass or very fine plastic, fiber optic cable can transmit light signals from one location to another at high speed using light refraction as its working principle. The light source used is a laser or LED. Fiber optics have become a major component of the telecommunications world.
Optical fiber has a unique working principle, because it does not use an electric current, but instead uses a stream of light that is converted from an electric current so that it will not be disturbed by electromagnetic waves. The constituent material is glass fiber which is useful for getting high light reflection from the mirror so that the data will be transmitted quickly at an unlimited distance.
Fiber optic cable components include:
  1. Core part (Core)
    The core of optical fiber is made of glass material with a very small diameter (diameter about 2 μm to 50 μm). A larger diameter optical fiber will make performance better and more stable.
  2. Cladding Section Cladding
    section is a protective part that directly covers the optical fiber. Usually the size of this cladding is 5 μm in diameter to 250 μm. Cladding is made of silicon, and the composition of the material is different from the core. In addition to protecting the core, cladding also functions as a guide to light waves that reflect all translucent light back to the core.
  3. Coating / Buffer
    Section The coating section is a coat of different optical fibers from cladding and cores. This coating layer is made of elastic plastic material. Coating serves as a protective layer from all physical disturbances that may occur, such as curvature of the cable, humidity in the cable.
  4. Strength Member & Outer Jacket Section
    This layer is a very important part because it is the main protector of a fiber optic cable. The strength member and outer jacket layers are the outer portion of the optical fiber that protects the cable core from various physical interference directly.
The advantages of fiber optic cables include:
  1. High transmission speed (1GB / s) and can reach long distances
  2. Rust resistant
  3. Cable size is small and flexible
  4. Not disturbed by electromagnetic waves and radio
  5. Prevents short circuit because it does not contain electricity
  6. Minimal distortion
With the advantages above, optical fiber is superior to other cables. So it is not strange if this cable is the main choice for large network users and requires a high speed rate.

What Are Backlinks?

By
   Backlinks (also known as “inbound links”, “incoming links” or “one way links”) are links from one website to a page on another website. Google and other major search engines consider backlinks “votes” for a specific page. Pages with a high number of backlinks tend to have high organic search engine rankings. https://plus.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://plus.google.com/url?q=https%3A%2F%2Fwww.honeywebsolutions.com%2F https://plus.google.com/url?q=http%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://www.google.com/url?sa=t&url=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://images.google.de/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.de/url?q=ht...

If we detect N photons from a coherent state of light for a measurement,

By Steve Rogers,
Short answer: A good order of magnitude rule of thumb for the maximum possible bandwidth of an optical fibre channel is about 1 petabit per second per optical mode. So a "single" mode fibre (fibre with one bound eigenfield) actually has in theory two such channels, one for each polarisation state of the bound eigenfield. I'll just concentrate on the theoretical capacity of a single, long-haul fibre; see roadrunner66's answer for discussion of the branching in an optical network. The fundamental limits always get down to a question of signal to noise in the measurement (i.e. demodulation by the receiver circuit). The one, fundamentally anavoidable, noise source on a fibre link is quantum shot noise, so I'll concentrate on that. Therefore, what follows will apply to a short fibre: other noise sources (such as Raman, amplified spontaneous emission from in-line optical amplifiers, Rayleigh scattering, Brillouin scattering) tend to become significant roughly in pro...

Fiber optics have seen recent advances in technology

By Steve Rogers,
Fiber optics have seen recent advances in technology. "Dual-polarization quadrature phase shift keying is a modulation format that effectively sends four times as much information as traditional optical transmissions of the same speed." [14] Receivers The main component of an optical receiver is a photodetector which converts light into electricity using the photoelectric effect. The primary photodetectors for telecommunications are made from Indium gallium arsenide. The photodetector is typically a semiconductor-based photodiode. Several types of photodiodes include p-n photodiodes, p-i-n photodiodes, and avalanche photodiodes. Metal-semiconductor-metal (MSM) photodetectors are also used due to their suitability for circuit integration in regenerators and wavelength-division multiplexers. Optical-electrical converters are typically coupled with a transimpedance amplifier and a limiting amplifier to produce a digital signal in the electrical domain from the incoming opt...
