With panels made in metal case with bench support and the electrical scheme on the front panel. The board must consist of a fiber optics transmission system that can be configured to experiment both digital and analogue signal transmission.
 
Technical Features:
The board must include the following elements: a TTL input digital transmitter, a digital receiver with data regenerator, an analogue transmitter with continuous variation of the working point of the emitting diode, a variable gain analogue receiver, auxiliary devices (continuously variable frequency clock generator, bit pseudo-random sequence generator, with single pole / NRZ /Biphase / Manchester TTL line coding), internal test signal frequency: 100 ÷ 800 kHz, multi mode plastic fibre with fast connection terminals (two fibres must be  provided: 50 cm and 5 m long respectively), optical transmitter and receiver: 880 nm, 50 MHz; LED diode optotransmitter emitting at 660 nm and PIN diode optoreceiver with integrated transimpedance amplifier.

This panel must include the elements for the experimental study of the following topics:

• Use of the optical fiber as transmissive mean of the information
• Light modulation for the information coding and transport
• Familiarisation and study of the characteristics of the devices emitting and receiving the optical radiation
• Carrying out of an F.O. experimental connection for the digital transmission
• Carrying out of an F.O. experimental connection for the analog transmission
• Familiarisation with different line codes used for the coding and the transmission of digital signals.

With this board it must be possible to perform the following exercises:

• Architecture of fiber optics systems
• NRZ, BIPHASE, MANCHESTER coding
• Optical transmitter and receiver
• Transmission speed
• The digital signal generator
• Transmission of digital signals
• Transmission of analog signals

It must be mounted on an insulated didactic module, it must  show a schematic diagram and 2 mm terminals for the electrical connection.
The board must be supplied complete with a set of stackable, plug-in cables of suitable lengths and colors and with a training manual.
Power Supply: ± 15 VDC, 300 mA.
