lows:
Screw-mounting Model Cylindrical Model
Use a proper-sized wrench.
Fiber Connection and Disconnection
The E3X Amplifier Unit has a lock button. Connect or discon-
nect the fibers to or from the E3X Amplifier Unit using the fol-
lowing procedures:
1. Connection
Open the protective cover, insert the fibers according to the fi-
ber insertion marks on the side of the Amplifier Unit, and lower
the lock button.
2. Disconnection
Remove the protective cover and raise the lock button to pull
out the fiber.
Note:To maintain the fiber properties, confirm that the lock is
released before removing the fiber.
3. Precautions for Fiber Connection/Disconnection
Be sure to lock or unlock the lock button within an ambient
temperature range between -10°C and 40°C.
Cutting Fiber
• Insert a fiber into the Fiber Cutter and determine the length
of the fiber to be cut.
• Press down the Fiber Cutter in a single stroke to cut the fi-
ber.
• The cutting holes cannot be used twice. If the same hole is
used twice, the cutting face of the fiber will be rough and the
sensing distance will be reduced. Always use an unused
hole.
• Cut a thin fiber as follows:
