FIBER CLEAVING PROCEDURE
for FURUKAWA S310NT FIBER
CLEAVER
1. GENERAL
1.1 These instructions describe the proper method of cleaving fiber with the Furukawa S310 Optical Fiber Cleaver that is provided with Ortronics’
Field Installation Kits. This procedure is one that requires practice, technique, and patience. It
is recommended that you practice prior to attempting to actually install an optical connector.
Safety glasses with side shields must be worn throughout this procedure.
2. DESCRIPTION OF THE S310 FURUKAWA OPTICAL FIBER CLEAVER
2.1 A – Fiber Hold Lever
B – Arm
C – Fiber Holder
D – Blade
E – Fiber Stop
F – Leaf Spring
3. CUTTING SEQUENCE
3.1 Before proceeding to step 3.2, the fiber must be prepared per either Ortronics’ Breakout Kit
Instructions, or the Optimo Installation Instructions.
3.2 Fig. 3.2 shows the fiber components.
3.3 Depress the Fiber Hold Lever (A) to raise the Fiber Holder (C) and carefully
position the bare fiber into the cleave tool as shown in Fig.’s 3.3 and 3.3.1. For
loose tube applications, position the 250 micron coating against the Fiber Stop (E).
For tight buffer applications, position the 900 micron buffer against the Fiber Stop
(E). Fig. 3.3.1 depicts the loose tube application. At this point the bare fiber will
be positioned under the Fiber Holder (C). Gently release the Fiber Hold Lever (A)
to clamp the bare fiber.
3.4 While gently supporting the fiber as shown in Fig. 3.4, apply light pressure to Arm
(B) so that the pad lightly and momentarily touches the leaf spring (F) as shown
in Fig. 3.4.1. The blade (D) is spring loaded to control the amount of force
introduced to the fiber. Release Arm (B) while keeping the fiber in place.
CAUTION: When performed correctly, this operation will score the fiber
only. It should not result in fiber breakage. This step requires practice, and
if not performed properly, will create a poor cleave and result in high
insertion loss.

FIBER CLEAVING PROCEDURE
for FURUKAWA S310NT FIBER
CLEAVER
3.5 While gently supporting the fiber, slowly and carefully bend the leaf spring in a downward direction until the fiber breaks, as shown in Fig.
3.5. Be careful not to over bend the leaf spring. Over bending can cause permanent deformation to the leaf spring, which may justify
replacement.
4. INSPECTION OF THE CLEAVE
4.1 Using the microscope that was provided with your Ortronics Breakout Kit, verify that the cleave is acceptable per Fig. 4.1. The cleave
should be sharp and perpendicular to the longitudinal
axis of the fiber as shown in Fig. 4.1.2. If necessary,
repeat steps 3.1 through 4.1.
4.2
Discard fiber waste in the bottle provided with the Ortronics
Field Installation Kit.
4.3 Keep the bare fiber damage free and clean. Do not touch the
bare fiber with your fingers. Proceed to perform the installation
per either Ortronics’ Breakout Kit Instructions, or the
Optimo Installation Instructions.
