Example of a fiber cable cleaner (source: Fiber Instrument Sales, www.fiberinstrumentsales.com).
• Clean the jumper and connect to the Optical Power Meter.
• Check that the front panel LASER LED is lighted green; if not, press the LASER ON/OFF
button to turn the LED to green.
• Operate the power meter per the owner's manual to read the output level. See table in
chapter 4 to convert mW to dBm if needed.
• When finished, press LASER ON/OFF to turn off the output (LED turns red), and unplug
the power cord

4.3 RF Input Connections

Connect the RF input signals to the rear panel F-connector labeled RF IN. In most cases, the
input signal will have more than 6 channels (90 MHz of occupied bandwidth). If this is correct,
proceed to check that the input level is in the range described in the Specifications section (ap-
proximately 15 dBmV as a nominal value). Use a RF spectrum analyzer or signal power meter.
If you have less than 6 channels (90 MHz. of occupied bandwidth), see the section below
You may monitor this input signal from the front panel; the PFT includes a -20 dB directional
coupler to divert a small amount of this signal to the front panel F-connector labeled RF TEST
PORT. The -20 dB level is approximate and varied do to parts variations. If the level is critical
to your monitoring application, you may wish to measure the RF signal as you connect to the
rear panel (with power on), then immediately measure the level at the front panel test port and
note the exact difference.
