1. Connect Optical Light Source to Splitter input port. 2. Set the reference power level to 0dBm. 3. Connect Optical Power Meter or OTDR to Splitter output port 1 and measure

received power level. 4. Measure the remaining Splitter output ports and write the test results. 5. After measuring the Splitter output ports, connect Optical Power Meter or OTDR

in the Drop cable (at rosette end). 6. Measure the received power level and write the test results for each Flat. 7. After completing the test measurements in each Flat, compare the measured

levels based on the Power Level calculation below. Power Level = Splitter Output measured level – Losses Where Losses are as follows; Patch Cord = 1 X 0.6dB SC/APC Adaptor Insertion Loss = 2 X 0.2dB Fast-field Connector = 2 X 0.4dB Drop Cable = 0.35dB/km Example: Flat604 with 40 meters Drop cable, and Splitter1 Port32 measured output level is -19dBm. Power Level = -19dBm – (0.6+0.4+0.8+0.014)dB = -19dBm – 1.814dB Power Level= -20.814dBm

8. If the difference between measured levels and calculated levels is more than 1 dB, then check patch cords, Drop cable and connectors for any faults and rectify.

9. Follow steps 1 to 8 for the remaining Splitters.
