Record 5 2009-08-28

English

Subject field(s)
  • Optical Telecommunications
DEF

A technology that uses light propagating in free space to transmit data between two points.

CONT

Free-Space Optics (also known as FSO, Wireless Optics or Optical Wireless) is an optical data, voice and video transmission system. Like fiber optic cable, wireless optics communication systems use laser light to transmit a digital signal between two transceivers. However, unlike fiber, the laser like is transtmited through the air (free-space) instead of through a glass strand. In order for the digital signal to be transmitted and received, there must be clear line of site between each wireless optics unit. In other words, there should be no obstructions such as trees or buildings between the transceiver units.

CONT

The technology is useful where the physical connection of the transmit and receive locations is difficult, for example in cities where the laying of fibre optic cables is expensive. Free Space Optics is also used to communicate between space-craft, since outside of the atmosphere there is little to distort the signal. The optical links usually use infrared laser light, although low-data-rate communication over short distances is possible using LEDs [Light Emitting Diode]. IrDA [Infrared Data Association] is a very simple form of free-space optical communications. Distances up to the order of 10 km are possible, but the distance and data rate of connection is highly dependent on atmospheric conditions.

OBS

In Information Technology and Communications, IrDA refers to Infrared Data Association, a standard for communication between devices (such as computers, PDAs and mobile phones) over short distances using infrared signals.

Subject field(s)
  • Optical Telecommunications
CONT

Optical burst switching is a promising hybrid approach between coarse grain optical circuit switching and fine grain optical packet switching. The benefit of optical burst switching(OBS) over conventional circuit switching is that there is no need to dedicate a wavelength for each end to end connection. In addition, optical burst switching is more viable than optical packet switching as the burst data does not need to be buffered or processed at the cross connect. This allows the strengths of optical switching technologies to be leveraged effectively and the problem of buffering in the optical domain to be circumvented.
