To ensure maximum power and to avoid erroneous readings always inspect
fiber ends and make sure that they are clean as explained below before
inserting them into the port. Coherent Solutions is not responsible for
damage or errors caused by bad fiber cleaning or handling.

AUTION
The type of optical connectors on the DopplerPXIe module can be found
printed on the front plate of the module and in the separate Spec sheet
provided. Joining mismatched connectors will damage the ferrules.
4.1 Cleaning and Connecting Optical Fibers
To connect the fiber-optic cable to the port:
1. Inspect the fiber using a fiber inspection microscope. If the fiber is clean, proceed to connecting
it to the port. If the fiber is dirty, clean it as explained below.
2. Clean the fiber ends as follows:
2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl alcohol.
2b. Use compressed air to dry completely.
2c. Visually inspect the fiber end to ensure its cleanliness.
3. Carefully align the connector and port to prevent the fiber end from touching the outside of the
port or rubbing against other surfaces. If your connector features a key, ensure that it is fully
fitted into the port’s corresponding notch.
4. Push the connector in so that the fiber-optic cable is firmly in place, thus ensuring adequate
contact. If your connector features a screw sleeve, tighten the connector enough to firmly
maintain the fiber in place. Do not over tighten, as this will damage the fiber and the port.
Note : If your fiber-optic cable is not properly aligned and/or connected, you will notice heavy loss and
reflection.
Coherent Solutions uses good quality connectors in compliance with EIA-455-21A standards.
To keep connectors clean and in good condition, Coherent Solutions strongly recommends
inspecting them with a fiber inspection probe before connecting them. Failure to do so will result in
permanent damage to the connectors and degradation in measurements.
