2.1 New Product

Procedure:

The plugs and couplings for pretest measurements were cleaned as described in section 1.7.4 of the TIA-568A.

Measurements of loss and return loss at wavelengths of 850 nm and 1310 nm were performed at ambient

conditions before any environmental testing.

Sample Size: 30

Results:

2.2 Cold (Group 0)

Procedure:

Measurements of loss and return loss at 850 nm and 1310 nm wavelengths are performed at the start and the finish

of the test at 22

°C. The test samples are subjected to 96 hours (4 days) at -10°C. Additional measurements are

made every 15 min. at -10

°C during test to monitor performance.

Sample Size: 10
