Step 6: 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.The power meter reading should be at least 500 W.

Step 7: Set the power meter to dB relative (press the dB key), and set

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

0.0 dB ±0.1 dB.

Step 8: Set the OA 5000 DISABLEbutton to on (lit).

NOTE

Themeasurement in step 9 is near the noise floor of the power

meter,so it may be necessaryto repeat the meter zero (withsensor

capped) and the measurement several times to get a valid result. If

an average reading lower than about ---97dB can’t be obtained

(except for the OA 5032), it might be due to noise in the sensor. A

laser with a higher pow er output might be needed to imp rove the

range of the measurement.

Step 9: Verifythe OA 5000 shutter attenuation by checking that average

(not peak) value of the power meter reading is ---100dB or lower (more

negative), except ---90dB or lower for OA 5032.

NOTE

Stablelight levels must be maintained throughoutthe insertion loss,

attenuationaccuracy,and repeatability tests. Use only fiber optic

connectors that are clean an d in good condition. It m ay be neces-

sary to remove the OA 5000 bulkhead connectors and clean the

OA 5000 connectorsand fibers (s eeAppendix F).

Step 1: Leave the fibers connected tothe 1310 nm laser and the long

wavelength sensor.Disconnect the fibers from the OA 5000, and con-

nect the fibers together using an FC/FCadapter.

Step 2: Assure that the wavelength displays ofthe OA 5000 and the

power meter are set to the actual wavelength (not the nominalwave -

length) of the laser,within ±1 nm.

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

700 W or more. Set the power meter to dB relative mode(press the

dB key), 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.
