This corresponds to working within the AEL for Class 1, Class 2, Class 3A and Class 3B lasers, therefore, please take note of the following safety warnings:

5、 Under no circumstances should a connector end-face, prepared optical fi bre or fractured optical fi bre be viewed directly unless the power received from the fi bre is known to be safe (as defi ned by IEC 60825) and under local control. AVOID EXPOSURE TO BEAM if the accessible radiation is within t

Before attempting use of your new instrument please take the time to read this user guide, ultimately this will save you time, advise you of any precautions you need to take and could prevent damage to yourself and th

9、e instrument. The MPM2000 and MPM2000H are advanced optical power meters that can be used for optical loss testing of fi bre optic cables. These have been pre-calibrated for absolute power levels with reference to 1mW (dBm) for 850nm, 1300nm, 1310nm and 1550nm laser wavelengths. A further ten wavele

10、ngths can be programmed in at the factory. With its high-resolution reading (to 0.01 dBm) and wide dynamic range (+10dBm to 70dBm for MPM 2000, +20dBm to 60dBm for MPM 2000H) this instrument favours single mode operation and is supplied with a single- mode patch lead. However it can also be used wit

11、h multi-mode fi bre optic cables and corresponding multi-mode patch leads are available in the Accessories. With such a wide dynamic resolution, this product is ideal for CATV and other long distance transmission applications. 5 1.0 User Controls and Display 1.1 ON/OFF Switch To turn the unit on, de

12、press the ON/OFF switch. To disable the Auto-Power-Off during switch on, hold the ON/OFF switch down until the Auto-Off annunciator on the LCD disappears. In Auto-Power-Off mode, the unit will power off after 15 minutes unless a switch is pressed. To turn the unit off, press the ON/OFF switch. 1.2 Z

13、ero Switch The zero switch is used to automatically zero the optical power meter before making power level measurements in the -45 to 60dBm (H series) or -55 to -70 dBm range. To zero the meter, fi t a blanking adapter to the sensor holder and then depress the zero switch. On completion the LCD indi

14、cates -62.00 dBm (H series) or -72.00 dBm and UR (under range) is displayed. NOTE. When making low level power measurements in the last 10dB of dynamic range, allow more time for the meter indication to settle due to extra auto averaging. 1.3 dBm / Watts Switch The dBm /Watts switch selects the meas

15、urement mode and returns the unit to dBm measurement mode if dB REL is selected. 1.4 Wavelength Switch () The wavelength switch allows the correct wavelength to be selected prior to making a measurement as indicated on the small 4-digit display. NOTE: The wavelength switch is disabled during dB REL

16、measurements 1.5 dB REL Switch The dB REL switch allows measurements to be made relative to the previously stored reference power level, indicated on the small 4-digit display. All further measurements will be referenced against this previously stored power level. To store a new reference power leve

17、l, press and hold the dB REL switch for 3 seconds. After the 3 second delay the main 4-digit display will indicate 0.00 and the new stored reference level will be indicated on the small 4- digit display. To return to dBm measurement mode, press the dBm/Watts switch. 6 2.0 Operation This instrument c

18、an be used for multiple applications including Optical Loss Testing, Optical Continuity Testing, Acceptance Testing of Fibre Transmitters and Received Power Testing of optical receivers. There are multiple techniques to achieve these types of tests, but a typical procedure is detailed below: 2.1 Opt

19、ical Loss Testing Take an optical light source and power meter with appropriate patch cords and mating adapter (uniter) to match the optical fi bre under test. Clean all the connectors and connect the light source via the fi rst patch cord, the uniter and the second patch cord to the power meter so

20、the attenuation of both cords can be eliminated. The link to be tested is then inserted between them so the optical loss associated only with this link can be found. This test is normally repeated multiple times with the interconnections between the patch cord and the fi bre under test disconnected

21、and reconnected before each time and an average result taken to ensure repeatability and stability. 2.2 Optical Continuity Testing Use an optical light source (of a known output power) and power meter with patch leads of a known optical loss and a uniter matched to the optical fi bre under test. Cle

22、an all the connections and insert the link to be tested between the light source and the power meter. Measure the output of the light source through the fi bre under test and check that it is above a pre- determined power level. This is a more simple go, no go test. 2.3 Acceptance Testing of Fibre T

23、ransmitters Use a power meter with a suitable dynamic range for the transmitter under test and patch leads of a known optical loss. Clean all the connections and connect the power meter to the transmitter via the patch cord. Turn on the transmitter and allow the output to stabilise before measuring

24、the output and comparing the result to an acceptance standard or versus historical data. This test is normally repeated multiple times with the interconnections disconnected and reconnected before each time and an average result taken to ensure repeatability and stability. 7 2.4 Received Power Testi

25、ng Use a power meter with a suitable dynamic range for the receiver under test and an adapter to match the connections on the receiver. Clean all the connections and connect the power meter to the fi bre supplying the receiver under test so that the power meter is now where the receiver would normal

26、ly go. Turn on the optical transmitter of the fi bre system and allow the output to stabilise before measuring the output at the receiver and comparing the result to the input specifi cations of the receiver. This test is normally repeated multiple times with the interconnections disconnected and re

27、connected before each time and an average result taken to ensure repeatability and stability. The MPM2000/MPM2000H are supplied and confi gured for use with a 6LR61 (PP3) dry cell. A 12V DC charger (See Optional Accessories) can be used as a dual power source; this will not apply a charge to the dry

28、 cells while fi tted. Alternatively, within the battery compartment there is a switch to change the battery type from alkaline to NiCd/NiMh. If the DC charger is now connected to the instrument with rechargeable batteries in it (the switch is set to NiCd/NiMh) then the batteries will start to rechar

29、ge. Allow 14 16 hours to fully charge a rechargeable battery. Do NOT attempt to recharge alkaline cells, over heating would occur and the instrument may be damaged. When the switch is set to NiCd/NiMh, only fi t rechargeable cells. 3.0 Batteries 8 4.0 Specifi cation 4.1 Optical Specifi cation Sensor
