Appendix G: Product Verification

Appendices

A --- 2 8

Step 1: Disconnect the fibers from the OA5000 and 1310 nm laser.

Connect the 1550 nm laser to the inputfiber and the long wavelength

sensor to the output fiber.Connect the fibers together using an FC/FC

adapter.Set the laser to CW (unmodulated) mode, and set the laser

power level (if adjustable) tomaximum, but not more than 2 mW. Turn

on the laser.

Step 2: Set the wavelength displays ofthe OA 5000 and the power

meter to the actual wavelength (not the nominalwavelength) of the laser,

within ±1 nm.

Step 3: Set the power meter to W(watts) mode. The reading should be

at least 400 W. Set the power meter to dB relative (dB key) mode, and

set the dB reference (Disp-->Ref). The power meter should read 0.0 dB

±0.1 dB.

Step 4: Disconnect the fibers from the FC/FCadapter, and connect

them to the OA 5000.

Step 5: Set the OA 5000 attenuation to0 dB, and the DISABLEbutton

off (unlit).

Step 6: The power meter reading is the insertionloss of the OA 5000.

Check that the power meter reading is ---2.5dB or higher (more posi-

tive).

NOTE

During theremaining steps, do not disturbthe connections and

fibers.

Step 7: Set the dB reference (Disp-->Ref) at the power meter. The

power meter reading should be 0.00 dB within ±0.01 dB.

Step 8: Set the OA 5000 to each of the settingsin the table below, and

check that the power meter reads within the listed accuracy limits.At

30 dB, note the reading.

Step 9: Set the OA 5000 to 0 dB. Check that the power meter reads

0.00 dB within the repeatability sp ecification (±0.05 dB).

Step 10: Set the OA 5000 to 30 dB. Check that the power meter reads

the same as in step 8, within the repe atability specification (±0.05 dB).

Step 11: If the readings in steps 9 and 10 do notmeet the repeatabilit y

specifications, check the connections,and repeat steps 7 to 10.
