| Receiver output 1 | d.c. to greater than 5kHz |
| Receiver output 2 | 0 to 5V digital, below 20Hz to above 300kHz |
| Power requirements | 5 to 6V smooth d.c., reverse polarity protected |
About This Product
The transmitter's internal 300 kHz oscillator is normally used for the speed of light experiment, while external signals of 0 to 2 V d.c. linear or up to 5 V digital can also modulate it. Its 0 to 2.5 V monitor output connects to an oscilloscope or measures the LED operating current. At the receiver, a solid state photo-detector feeds an analogue output with zero-set and gain controls and a high speed digital output. The Comprehensive Fibre Optics Kit is available for supply within India and for export to Angola, Uzbekistan, Kiribati, Republic of the Congo, Zimbabwe and Bangladesh.
Frequently Asked Questions
Q1. Does the fibre need special connectors?
No. The plastic fibre can be cut to any desired length with a sharp knife and needs no special terminating devices; it uses simple push-in connections for 1 mm fibres.
Q2. Can the transmitter and receiver share a power supply?
Yes. Both need 5 to 6 V smooth d.c. and may share the same power supply if desired.
