8. Check the connected optical fiber and ensure that neither its optical connector nor
optical fiber is subjected to stress. Ensure also that the bending radius of the cable
satisfies its minimum bending radius requirement.
TIP
The bending radius for a typical 3mm diameter optical fiber must not be less than 3cm.
9. If the DTSX3000 is installed in a cabinet, ensure that the cabinet door does not
touch the optical fibers when it is closed.
10. With the sensor optical fiber connected to the DTSX3000, start measurement and
check that distributed temperature measurement is normal. If not, redo the cable
routing and connection.
If the DTSX3000 still fails to measure temperature distribution normally, either the
optical fiber or the DTSX3000 itself may be faulty. Repeat the measurement with
another cable to isolate the fault.
11. Apply similarly to connection with the DTOS2L, DTOS4L or DTOS16L optical
switch module.
For easier connection with the DTOS4L or DTOS16L, which has many optical
connectors, attach optical fibers to inner optical connectors before outer optical
connectors, temporarily detaching existing optical fibers from outer optical
connectors if necessary.
