CAUTION
Handling precautions for optical fibers:
- Use optical connectors and optical fibers that meet product specification
requirements.
Connecting the wrong type of optical connector to the DTSX3000 may damage not
only the optical connector but also the optical connector of the DTSX3000 or the
optical switch module.
- Do not apply excessive force on the lever of an optical connector.
Pressing down too hard or too much on the lever may damage it.
- Before connecting an optical connector, clean its end face to remove dirt, dust, oil
or other contaminants.
Contaminants on optical connectors may lead to fiber loss and optical reflection
and in turn failure to meet the DTSX3000 or the optical switch module performance
specifications. Moreover, the laser pulse peak power of this instrument is about 30
W, which may cause contaminants to be fused to and thus damage the end face of
the optical connector.
- Ensure that the end face of an optical connector is free of scratches.
Using an optical connector with a scratched end face may damage the optical
connector of the DTSX3000 or the optical switch module.
Never connect an optical connector with a scratched end face.
- When connecting an optical connector, insert it gently and vertically into the optical
connector of the DTSX3000 or the optical switch module.
Improper connection, lateral movements and insertion by force may damage not
only the optical connector but also the optical connector of the DTSX3000 or the
optical switch module.
Ensure that a connected optical connector is locked in place.
- Optical fibers must be routed according to routing instructions and not be subjected
to excessive tension, lateral pressure, tight bending, or twisting.
- Disconnecting an optical connector improperly or forcibly may damage not only the
optical connector but also the optical connector of the DTSX3000 or the optical
switch module.
- Do not open the shutter, which protects the ferrule of an optical connector, in
normal use.
The shutter will open (not visible externally) automatically when the optical
connector is connected.
If you need to check or clean the end face of the optical connector, open the shutter
of the optical connector in a clean, dust-free place.
- The optical connector of the DTSX3000 or the optical switch module comes with its
protective cap.
Leave the cap in place except when connecting an optical fiber cable.
- Using an optical connector or optical fiber that does not meet product specification
requirements, using an optical connector with a scratched end face or improper
handling of optical connectors may result in hardware failure. Hardware repair or
parts replacement necessitated by improper use is chargeable even during the
warranty period.
