2.3 Temperature Life (Group 0)

Procedure:

Testing is performed on samples after exposure to the Cold Test. Measurements of loss and return loss at 850 nm

and 1310 nm wavelengths are performed at the start and finish of test at 22

°C. The test samples are subjected to

336 hours (14 days) at 60

°C. Additional measurements are made every hour at 60°C during test to monitor

performance.

Sample Size: 10

2.4 Humidity (Group 0)

Procedure:

Testing is performed on samples after exposure to the Temperature Life Test. Measurements of loss and return

loss at 850 nm and 1310 nm wavelengths are performed at the start and finish of the test at 22

°C, and every 15

min. during the test at 40

°C with 90%-95% Relative Humidity.
