LT-0500 Fibre Video & Audio TransmissionLT-0500 Fiber Video and Audio Transmission

This experiment comprises two drums of multi-mode fiber with one 1000 m and two 2000 m long multi-mode fiber With this set data transmission segments can be realized with a length of 1000 m, 2000 m and 3000. The fiber drums are equipped with ST fiber jacks and by means of the provided fiber patch cable they can be interconnected. As signal sources a color CCD Video camera and a CD - Player as audio source are used. They are connected to the fiber transmitter which converts the electronic signals into digital optical signals which are guided via the optical fiber to the optical receiver where the signals converted back to electronic audio as well as video signal. These signals are connected to a regular TV to watch the transmitted video as well as listen to the simultaneously transmitted audio. The optical signals having a wavelength of 1.3 µm and are detected in addition by the optional fast InGaAs photodetector. The amplitude can be shown on an oscilloscope and the amplitude measured for the 3 different length of the data segment. For each measurement the input and output power is measured and from this relation the fiber attenuation calculated.

Principle of data transmission via optical fiber
A. Principle of audio and video data transmission via optical fiber
The video signal (yellow lines) is generated either by the CCD camera or by the DVD player, whereby the DVD player provides the audio stereo signal (red and black). The video and audio signals are converted by the transmitter to modulated optical signals and made available at a ST panel jack. Optical glass fiber with a length of 1000 m and 2000 m are coiled to a drum and provided with ST panel jacks. The optical connection between the transmitter and the first fiber segment is established by means of a ST fiber patch cable. In the same way the two fiber segments are linked to each other and connected to the receiver. The optical signal is converted back to the video as well as audio signal and are connected via standard BNC and cynch connection cable to the TFT monitor.
