any propellant.
2. Spray the clean compressed air on the connectors to remove any loose
particles or moisture.
3. Moisten a clean optical swab with isopropyl alcohol then lightly swab the
surfaces of the connectors.
4. Spray the clean compressed air on the connectors again to remove any loose

Connecting Signals
Attach the fiber optic cable with an FC/PC connector to the FC/PC input
receptacle as follows:
1. Carefully align the keyway on the receptacle with the key on the connector.
2. Tighten the nut lightly with finger pressure only.
The input of the ORR24 Optical Reference Receiver can couple to optical fibers
with a core diameter of up to 9
mm. Alternate types can be coupled by use of an
FC-FC jumper and the FC-FC, FC-ST, FC-SC adapters. (Refer to Optional
accessories on page 21.)
CAUTION.
To maintain the high performance (low return loss) of the reference
receiver, connect an adapter and cable between the input of the reference
receiver and the device under test. When you make connections to other devices,
leave the adapter and cable in place to protect the optical connector of the
reference receiver from wear.
