Optical Passive Device including: optical fiber, connector, filter, CWDM/DWDM module, coupler, splitter, isolator, optical switch, circulator, attenuator
There are various types of optical passive devices, and the main reliability test specifications:
temperature dependent loss-TDL and temperature wavelength drift-TWD.
Test item | Test instruments | Options | Note |

Reliability test example description
Relevant test standard documents:-- EIA/TIA-455-3A/GR-1221/ GR-1209/ IEC 68-2-38
(1). Temperature Cycling Test
Temperature: -40°C to 70°C (±2°C) for CO -- user-defined
-40°C to 85°C (±2°C) for RT/UNC -- user-defined
Dwell Time at Extremes: ≥15 minutes – user-defined
Number of Cycles: 100 pass/fail, 500 for information for CO;500 pass/fail, 1000 for information for RT/UNC
Cyclic Moisture Resistance Test
Temperature Profile: Refer to below profile -- user-defined
Relative Humidity: 85-95% at 75°C; uncontrolled at 25°C & -40°C
Dwell Time at Extremes: 3 to 16 Hours – user-defined
Number of Cycles: 5 complete cycles (each complete cycle has 5 sub-cycles)
We can use the laser source, optical power meter, thermostat box, and optical switches, through the control software, achieve automatic temperature control, automatic switching test. In the field of production and manufacturing testing, the module + platform testing solution has great advantages in instrument expansion, data/report autosave, programmability and so on.
