1 Measuring of optical output and attenuation THEORY Measuring of optical output is the fundamental part of measuring in optoelectronics. The importance of an optical power meter can be compared to an ammeter in electronics. Wavelengths of 850nm, 1300nm and 1550nm (transmission windows ) are used for telecommunication transmission. It is an invisible radiation so it is not light (360nm 780nm) but an optical radiation (200nm 1000nm). In the visible range of a spectrum we speak about photometric variables and photometric measuring, that take into account the spectral sensitivity of the human eye. The optical radiation output P[W] represents the output transferred by radiation, i.e. it is determined by the amount of energy passing through a tracked area in a unit of a time. In optoelectronics, more usually the optical output L is measured in absolute decibels [dbm] which conveys a level of optical output in relation to 1mW. L = 10log [ ] [ ] P mw 1 mw [ dbm] By means of this variation L attenuation A in relative decibels [db] can be easily determined by the following equation A = L 2 L 1 where L 1 and L 2 are output levels obtained for example by measuring at the beginning and end of an optical line. Optical power meters have got a reference function that allows the storing of a reference value P 1 and then can measure the relative level L r of arbitrary optical output against this reference. The attenuation A is then A = L r P2 = 10log P 1 [ db] and can be read (except the sign) on the instrument display. Photodiodes (Si, Ge, InGaAs) are used as detectors. They achieve high sensitivity and low dark current. Their sensitivity is spectrally dependent; we must then set a power meter to the wavelength of the light source used. A detector area must be large enough to detect the entire radiation leaving the fibre (conventionally 2 3mm). Adapters to various types of optical connectors are used for fixing the fibre end. The adapter must ensure the alignment of the fibre and the detector and it must not obstruct the optical beam. Any impurity and dust will distort the measuring (diffusion and absorption) CLEAN! MEASURING Measure the optical power transmitted by a cable. Use a multimode cable GI 50/125 (orange) for λ = 850nm a 1300nm, and a single mode cable 1E9/125 (yellow) for λ = 1310nm and 1550nm. instruments: light source, power meter, coupling elements GI 50/125 (orange), 1E9/125 (yellow) process: 1. join the source (connector MM) to the power meter using the coupling element GI 50/125 (the left hand connector at the source, first clean the connector faces of the element) 2. turn on the source and set the wavelength to 850nm (λ button) 3. set λ = 850nm at the power meter 4. measure optical output L 1, P 1 5. set λ = 1300nm at the source 6. measure optical output L 2, P 2 7. set λ = 1300nm at the power meter 8. measure optical output L 3, P 3

2 9. set λ = 1310nm at the source, use 1E9/125 coupling element (first clean the faces), join it to the SM connector 10. set λ = 1310nm at the power meter and measure optical output L 4, P set λ = 1550nm at the power meter and at the source and measure optical output L 5, P 5 TABLE OF MEASURED VALUES No of meas L i [dbm] P i [mw] Question: One of measured values is wrong. Which one and why?

4 TABLE OF MEASURED VALUES GI 50/125 GI 62,5/125 L ref1 [dbm] L 1 [dbm] A 1 [db] L ref2 [dbm] L 2 [dbm] A 2 [db] Question 1: What value of attenuation is right and why? Question 2: Why is the value A 2 higher than A 1?

6 9. wrap launch cable around mode filter 5 times, attach launch cable to the meter and read L disconnect launch cable from the meter and attach it to the link, attach receive cable to the meter 11. read power L 4, calculate attenuation A f = L 3 L 4 source During the measuring, don t disconnect the launch cable from the source. The LED in the source may couple a slightly different amount of power into the launch cable when reconnected, ruining your reference set. TABLE OF MEASURED VALUES without filter with filter L 1 = L 2 = L 3 = L 4 = A = A f = Question: Compare values A and A f. Which of them is higher and why?
