Optical Input SC/APC Optical input to the unit.
Optical output from the return path unit.
Optical Out
It is imperative that back reflections be controlled to very low levels for good performance. This prod-
uct must be used only with angle physical contact (APC) connectors or fusion splices.
Pin Function
1 +12 Volts DC
2 Ground
3
Optical Status Flag. This is an open drain output that can sink up to
10 mA at +12 Volts. An external pull-up resistor is required. This
pin will be pulled low when the optical input is within optimal range
Power
4-Pin Weidmuller Con-
nector (See Figure 1.1
for location of pin 1)
4
Optical Input Power Meter Output. This is an analog voltage pro-
portional to the amount of light reaching the detector. The response
is 1 Volt per mW of input light.
RF Output F Connector RF output from the unit.
RF Test F Connector RF Test (-20dB) output for receiver.
RF Return Test F Connector RF Test (-20dB) output for return path module (if installed).
