Decentralized Fiber Optic Acquisition System

IFAC Proceedings Volumes, 1982
The paper describes a decentralized data acquisition system installed for a long term on-site test at a French power plant. Two local autonomous stations acquire the information from 24 channels; the data are continuously transmitted to a concentrator through two 600 m long optical cables at a rate of 0.96 Mbits/sec.

Optical switch for multimode optical-fiber systems

Optics Letters, 1979
A new type of optical switch is constructed of graded-index rod lenses. It is operated mechanically by small electromagnets. This switch is compatible with practical multimode-fiber communication systems. It has many outstanding features, such as low insertion loss (1.3–1.4 dB), low crosstalk ( 2 × 106 times), and small size (40 × 50 × 25 mm3).

Fiber optical holographic system

SPIE Proceedings, 1990
A fiber-optical holographic system is established as a holographic endscope. It can be used for recording the image holography to measure the vibration and deformation inner some objects.

Fiber Optic Systems

1999
One the greatest revolutions in data communications is the usage of light waves to transmit digital pulses through fiber optic cables. A light carrying system has an almost unlimited information capacity. Theoretically, it has more than 200 000 times the capacity of a satellite TV system.
