Fiber Optic Cable
A fiber optic cable is made of glass or plastic and transmits signals in the form of light pulses. An optical fiber is a thin flexible medium conducts pulses of light with each pulse representing a bit. A single optical fiber can support tremendous bit rates up to tens or even hundred of gigabits per second.
A thin glass fiber is encased in a plastic jacket which allows the fiber to bend without breaking. A transmitter at one end uses light emitting diode ( LED) or laser to send pulses of light down the fiber which are detected at the other end by a light sensitive transistor. Fibe optic cabling consists of a canter core surrounded by several layers of protective materials.
It transmits light rather than electronic signals eliminating teh problem of electrical interference. This make it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between buildings due to its immunity to the effects of moisture and lighting
Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is similar to copper cabling. However it is more difficult to install and modify.
What are the types of Transmission media? Signals are usually transmitted over some transmission media that are broadly divided in to two categories:- Guided Media: Th
Optimizing STP Because there is a separate instance of the spanning tree for every active VLAN, a separate root election is conducted for each instance. If the default switch p
What is Error Control ? Error control is both error detection and error correction. It allows the receiver to inform the sender of any frames lost or damaged in transmission an

Butterfly permutation This permutation is getting by interchanging the important significant bit in address with smallest significant bit.
Single company or organization owns this. They are usually LAN technologies. There can be multiple LANs in a campus or building linked together. They are sometimes known Intranet.
