E3X-N
Fiber Connection and Disconnection
E3X-NT/NM/NV/NVG
The E3X-N Fiber Amplifier Unit adopts a snap-locking system. Con-
nect or disconnect the Fiber Unit according to the following proce-
dures:
1. Connection
• E3X-NT
Lock lever
Fiber insertion mark
Fiber
E3X-NT
Remove the protection cover, in-
sert the fiber into the Unit, and
then lower the lock lever until a
click sound is heard.
• E3X-NM
Lock button
After inserting the fiber into the
Unit, press the lock button until a
click sound is heard.
This will fix the fiber.
After cutting the fibers using the Fiber Cutter (E39-F4), place an in-
sertion mark on the fiber so that it can be properly inserted into the
Amplifier. Insert the fiber into the Amplifier up to this insertion mark.
2. Disconnection
• E3X-NT
Remove the protective cover, raise the lock lever, and then pull out
the fiber.
• E3X-NM
Press the lock button again. The lock will be released and the button
will pop up. Pull out the fiber. Do not forcibly pull up the lock button.
(Be sure to pull out the fiber only after confirming that the lock has
been released in order to maintain the fiber characteristics.)

3. Precaution When Connecting or Disconnecting Fibers
Lock the fiber or release its lock under 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 fiber.
An insertion mark can be placed on the fiber to serve as a reference
when inserting the fiber into the Amplifier. Use the following proce-
dure.
Confirm through the Cutter hole that the fiber is inserted beyond the
insertion mark hole so that the insertion mark is properly indicated
and then press firmly down on the Cutter.
Insert the fiber into the Amplifier up to the insertion mark. Proper fi-
ber performance will not be achieved unless the fiber is inserted all
the way to the insertion mark. (This method is applicable to stan-
dard, 2.2-mm-diameter fibers only.)

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 dis-
tance will be reduced. Always use an unused hole.
Use either one of the two holes on the right (refer to the following
figure) to cut a thin fiber as follows:
1. An attachment is temporarily fitted to a thin fiber before
shipment.

2. Secure the attachment after adjusting the position of it in the
direction indicated by the arrow.
