1) Attaching Interface Cables:
The
attenuator is attached between two mating cables, replacing the
usual splice bushing. Refer to the instructions below
appropriate to the attenuator you are using.
Attach the input and the output cables directly to the female
receptacles on the attenuator as you would normally with a
splice bushing.
2) Setting the Attenuator Loss:
The ATT-110 can be set to any loss value within the operating
range desired using a fiber optic source and power meter, such
as found in the Advanced Fiber Solutions test kits. You can set
the loss either by measuring the actual loss, preferred for
testing system margin in the lab, or by setting the receiver
power level, when using them in an operating network.
3) Calibrating Actual Loss
If
you wish to calibrate the actual loss of the attenuator, you
need to measure the optical power going into the attenuator and
the optical power coming out, similar to testing the loss of a
jumper cable.
