Is light the only signal carrier in optical fibers?

Yes, light is the primary signal carrier in optical fibers. It travels through the fiber as pulses of light, typically in the form of laser or LED signals. Other signals such as electrical signals can be converted into light signals at the source and back to electrical signals at the receiving end.

What is EER rating on carrier model 50VRA48?

The EER (Energy Efficiency Ratio) rating for the Carrier model 50VRA48 is typically around 11.5 to 12.0, depending on specific configurations and testing conditions. This rating indicates the cooling output in British Thermal Units (BTUs) per hour divided by the energy input in watts. A higher EER value signifies greater energy efficiency, making the unit more cost-effective to operate. For precise specifications, it's advisable to consult the product manual or Carrier's official documentation.


Explain the term modulation. how does it help in data communication?

Modulation is the addition of information to an electronic or optical signal carrier. The modulation can be applied by turning the signal on and off.


What is the carrier frequency for an optical communication system operating at 1.55 llm?

The carrier frequency for an optical communication system operating at a wavelength of 1.55 micrometers (μm) can be calculated using the formula ( f = \frac{c}{\lambda} ), where ( c ) is the speed of light (approximately ( 3 \times 10^8 ) m/s) and ( \lambda ) is the wavelength in meters. Converting 1.55 μm to meters gives ( 1.55 \times 10^{-6} ) m. Thus, the carrier frequency is approximately ( 1.93 \times 10^{14} ) Hz, or 193 THz.

What is Difference between optical communication and microwave communication?

Only the frequency of the communications carrier. Microwaves are electromagnetic radiation in the frequency range of 3 gigahertz to 300 gigahertz. Electromagnetic radiation above those frequencies are considered "optical" even though you can see only a small percentage of them with your eyes.
