Cleaning Optical Connectors

Optical reflections from a discontinuity such as a poor connector interface appear on

an RF spectrum analyzer trace as stable variations in the noise floor amplitude that are

periodic with RF frequency. If the reflection is bad enough, it could impact the system

performance. By far, the most common cause for a large discrete reflection is a dirty

optical connector. A bit of dust or oil from a finger can easily interfere with, or block

this light. Fortunately, it is very easy to clean the connector.

Be sure to use the correct procedure for the given connector. When disconnected, cap

the FC/APC connector to keep it clean and prevent scratching the tip of the ferrule.

Alternative 1

Swipe the tip of the ferule 2-3 times with a

cotton swab soaked in alcohol. Let it air dry.

Alternative 2

Use a product specially designed for the

purpose.

5.2.6 Supply Power to the Repeater

Caution!

The antenna cables must be connected to the repeater before mains power is switched on. Alternatively the

antenna connections on the repeater can be terminated with 50ohm termination plugs.

Note! The repeater can be fed by 230 VAC 50 Hz, 115 VAC 60 Hz or -48 VDC.

Ensure that the right voltage is used.

Connect the

repeater to the

power supply

Power is connected to the repeater via a plinth inside the repeater.

The strain relief fitting is a Pg 13.5 suitable for a 6-12 mm cable diameter.

230 VAC Power Supply

Connect the power cable to the plinth with the phase linked to the brown cable,

neutral linked to the blue and ground to the yellow/green. See illustration below.
