Always use patchcords to connect to your DUT. This
protects the connectors of the optical test set, by
minimizing the number of connector changes.
The contact connector on the optical test set is angled. If
you are using a patchcord with straight (red) and angled
(green) connectors, make sure you connect the angled
connector to the optical test set.
Connecting to the optical test set with a straight connector
will damage it.
Before you connect any fiber-optic cable to the Lightwave
Component Analyzer, please ensure it has been properly
cleaned.
Fiber-optic connectors are easily damaged when
connected to dirty or damaged cables and accessories.
When you use improper cleaning and handling techniques,
you risk expensive instrument repairs, damaged cables,
and compromised measurements.

option you ordered, you will also have received two patchcords.
• option 021 includes patchcords with an angled and a straight
connector
• option 022 includes patchcords with two angled connectors
Using the patchcord ensures the best "ripple" performance
(lowest ripple) for your measurements. Two or more, straight
connector interfaces in the optical measurement path can cause
optical cavities. These result in frequency dependent
interference effects (ripple), which may significantly degrade the
performance of the LCA. This may impact user calibrations in
OE and OO measurements. We recommend you use the
patchcords supplied to minimize the number of straight
connections.
Using the patchcords also keeps service costs down, as the
adaptor patchcord can be exchanged easily.
