Advantages of optical fiber communication system compared to conventional communication system?
# Optical fibres can carry more information as opposed to conventional cables. # Optical fibres are not affected by radio frequency interferrence # Information carried in an optical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the light will travel to the thief)

What is Relationship between electrical and optical bandwidth for an optical fiber communication?
The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
What are the optical line coding methods?
Some common optical line coding methods include Non-return-to-zero (NRZ), Return-to-zero (RZ), Manchester encoding, Differential Manchester encoding, and amplitude-shift keying (ASK). These methods are used in optical communication systems to convert digital data into optical signals for transmission over optical fibers.
What is advantage and disadvantage of optical comparator?
Advantage: Optical comparators provide high magnification for accurate measurements, facilitate quick and easy inspection of parts, and are non-contact systems that prevent damage to sensitive components. Disadvantage: They may have limited accuracy compared to other metrology tools such as CMMs, may require skilled operators for precise measurements, and can be less effective for measuring complex or 3D features.
What is the meaning of pcos machine?
A PCOS machine, or Precinct Count Optical Scan machine, is an electronic device used in some countries for automated vote counting in elections. It scans and tallies paper ballots, providing a faster and more accurate way of tabulating votes compared to manual counting. These machines help ensure transparency and efficiency in the election process.
What is v parameter of optical fiber?
The "v parameter" of an optical fiber stands for the V number, which represents the normalized frequency within the fiber core. It is calculated based on the core diameter, operating wavelength, and numerical aperture of the fiber. The V number helps in characterizing the modal behavior and guiding properties of the optical fiber.
What are the advantages of using erbium doped fiber amplifiers in optical communication systems?
Erbium doped fiber amplifiers (EDFAs) are advantageous in optical communication systems because they can amplify optical signals without converting them to electrical signals, which helps maintain signal quality and speed. EDFAs also have a wide bandwidth and low noise, making them ideal for long-distance communication. Additionally, EDFAs are compact, reliable, and cost-effective compared to other amplification technologies.
What is advantage to transmit information by light rather than by electricity in wires?
Transmitting information by light, or optical communication, offers advantages such as higher bandwidth, faster speeds, and immunity to electromagnetic interference compared to traditional electrical wires. Light signals in optical fibers can travel longer distances with less loss, making it ideal for long-distance communication networks.
