Single mode fiber
Angled connectors
Optical loss < 15 dB
Below is a block schematic that shows the downlink path in the FOI and how the test port is connected.
As you can see there are two attenuators that can be set in the DL path, this allows for balancing the
input signals from two different signal sources so that they can share the dynamics of the laser properly.
The RF drive levels are measured and accessible in the web interface so that they can be checked. In the
future alarm levels may be added to these test points.
This interface is designed to work with SC-APC connectors (7° angled
physical connector) and single mode fibers only. All connectors between
the master unit and the remote unit should be of angled type,
otherwise problems with reflections will arise which may cause severe
problems in the system.
