What difference between copper cable and optical cable?
A copper cable transports electrical signals. An optical cable transports light signals.
Which types of electromagnetic waves can be used to send signals along optical fibers?
Only light is used to send signals along optical fibres. That's why this type of fibre is described as "optical". Fibres designed to conduct electrical signals are referred to as "wires".
How does an optical transmitter sends signals to the optical fiber?
Usually, there is a laser diode that is optically coupled to the fiber.
What is optical switching?
An optical switch is a switch that enables signals in circuits to be switched from one circuit to another.
Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.
Is optical fiber unidirectional?
The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
Which OSI is responsible for managing optical signals used for data communication?
physical
How can any individual IP packet be communicated electrically?
over cable, as optical signals over fiber, or wirelessly as radio signals
What is Optical line terminal?
An optical line termination (OLT), is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: - To perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. - To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
Which OSI LAYER responsible for managing optical signals use data communication?
physical
A modern device that often has its signals carried through wires or glass optical fiber is a what?
telephone
