The following are detailed steps and key indicators for testing the performance of fiber optic splitters, combining industry standards and practical tips:
Temperature should be maintained at 23°C ± 5°C and humidity < 85% to avoid test deviations.
Measure the input/output power difference using the shear method according to IEC 61300-3-2. The typical value should be ≤ 0.3 dB (1310/1550nm wavelengths).
The splitting ratio error is allowed to be ±5% (using a 1*8 splitter as an example).
Using the OTDR reflectometry method (IEC 61300-3-6), a PC endface ≥55 dB and an APC endface ≥60 dB are considered acceptable.
Measure the loss of each output port sequentially; the difference should be ≤0.8 dB (PLC model).
Cyclic testing within the -40°C to +75°C range ensures loss change of ≤0.5 dB.
Test Standards: YD/T 2000.1-2014 (PLC splitters), ISO/IEC 14763-3 (splitting ratio).
Recommended equipment: EXFO FTB-200 (loss test), Yokogawa AQ2200 (splitting ratio analysis).
