Removing Quad-adapter Interfaces from the Keysight
N7744/5A Multiport Power Meter
There are release levers on both sides of the quad-adapter for removing it from the
optical inputs.
Figure 22 Removing Quad-adapter Interfaces
1 Press the release levers on both sides of the quad-adapter to release
it from the front panel of the power meter.
2 You can now remove the optical connectors from the quad-adapter.
Always place the dust cap on unused connector interfaces.
You can use the quad-adapter dust caps to protect the four power meter inputs and
the rear of the quad-adapter, for example, when fibers are attached.
Polarization Maintaining Fiber
A Polarization maintaining fiber (PMF) output is standard for Keysight
N7711/4A tunable laser system sources. PMF is aligned to maintain the
state of polarization. A well defined state of polarization helps ensure
constant measurement conditions. The fiber is of Panda type, with TE
mode in the slow axis in line with the connector key.
