The Fibre-Optics Monitor is a versatile, fully portable product that has been designed for fibre-optics and general optics measurement applications. A high radiance LED in the transmitter ensures a good measurement performance for all types of multimode optical-fibres, including 50µm core graded index fibre.
 The package consists of:
  - An optical transmitter  
- A high radiance infra-red LED that provides good performance for all types of multimode optical fibres  
- A variable output control  
- A variable frequency square wave generator  
- Digital and analogue inputs  
- Power is from an internal battery, or single external d.c. power supply (9V to 15V) (power supply not supplied)  
- An optical receiver with a loudspeaker with analogue output, low impedance analogue output and variable analogue gain  
- Mean power monitor output  
- Silicon p-i-n diode mounted in connector receptacle  
- Comprehensive theory & experimental manual  
- Connectors, microphone, batteries  
- Robust carrying case 
 - EFO1101 Fibre Optics Trainer required  
- EFO1102 Fibre Optics Power Meter optional
