Which of the following medium is used for broadband local networks?
Which of the following medium is used for broadband local networks?
The correct option is B Optic fiber
The medium can be coaxial
cable, optical fiber, radio or twisted pair. In the context of Internet access,
broadband is used to mean any high-speed Internet access that is always on and
faster than dial-up access over traditional analog or ISDN PSTN services.
Fiber-optic communication is a method of transmitting
information from one place to another by sending pulses of light through an
optical fiber. ... Optical fiber is used by many telecommunications companies
to transmit telephone signals, Internet communication, and cable television
signals.
An optical fiber or optical fibre is a flexible, transparent
fiber made by drawing glass (silica) or plastic to a diameter slightly thicker
than that of a human hair.[1] Optical fibers are used most often as a means to
transmit light between the two ends of the fiber and find wide usage in
fiber-optic communications, where they permit transmission over longer
distances and at higher bandwidths (data rates) than electrical cables.
Fiber optics (optical fibers) are long, thin strands of very
pure glass about the diameter of a human hair. They are arranged in bundles
called optical cables and used to transmit light signals over long distances.
... Cladding - Outer optical material surrounding the core that reflects the
light back into the core.
