Introduction
General information
The AUTOCLEAVER LDF™is a high precision fiber cleaver, designed for cleaving of large diameter fibers (LDF), using the tension
scribe method. It provides outstanding cleaving performance for solid circular silica fibers, ranging from 230µm to 1000µm in
diameter. The unique and patent pending cleaving process generates typical cleaving angles of less than 0.5 degrees with large
diameter fibers.
The built-in microprocessor controls all parameters and settings, such as clamping, fiber tension and the exact position and
speed of the diamond cleave blade. This control of sensitive parameters guarantees a high cleaving repeatability and accuracy.
The fiber is held in place by a NYFORS LD1fiber holder, which is used to load the fiber into the cleaver. The NYFORS LDF fiber
holder is selected to match the diameter of the fiber coating or jacket. The v-groove clamping block, the distance plate and the
fiber height adjuster are selected to match the diameter of the fiber cladding. The NYFORS LD fiber holder, the distance plate as
well as the v-groove clamp block and the height adjuster work together as a fiber handling kit to ensure optimum cleaving
performance for a particular range of fiber size. These parts are optional when purchasing the cleaver. The parts are easily
exchanged by the operator to set the cleaver up for a different fiber size.
The cleaver is designed to generate a minimum amount of fiber waste, typically less than 20mm. An automatic waste disposal
system removes and collects any hazardous fiber scraps. The cleaver can be connected to a PC that gives access to all
programmable parameters, settings, show information and cleaver status.
If the NYFORS CLEAVEMETER™(interferometer) is used for fiber end inspection after cleaving with the AUTOCLEAVER LDF™,
the fiber under tested will automatically be aligned at the correct distance from the optics and within the coherence length of
the light. The interference pattern will then be shown instantaneously on the screen and be ready for evaluation.
The AUTOCLEAVER LDF™ can be configured for different fiber holder systems, like the Fujikura or Fitel edition cleaver. These
accommodate the Fujikura and Fitel Fusion Splicer Fiber Holders and special linear clamp inserts. See sections for respective
cleaver configurations.

Safety information
Safety warnings and precautions
The AUTOCLEAVER LDF™is a precision instrument and must be handled with care. Therefore, the following
safety rules and general precautions regarding the use and handling of the AUTOCLEAVER LDF™must
always be supervised by the user.
Operational safety warnings
General: The AUTOCLEAVER LDF™must only be used for cleaving optical fibers it was
designed for. Any attempts to use the device for any other purpose could
cause injury to the operator, damage to the cleaver blade or impair the
AUTOCLEAVER LDF™
Fiber waste collector: Never operate the cleaver without the fiber waste collector mounted on the
cleaver because of the risk of injuring to the operator
Eye protection: Always use approved eyeglasses to protect from potential fiber shatter
Connecting cords: Protect the cords from being walked on, being pinched, or sharply bent,
particularly where they connect to any device. Do not jerk, knot, expose the
cords to sources of heat or otherwise abuse the cord. When disconnecting
the cord, pull on the plug –do not pull on the cord. If a cord becomes
damaged in any way, stop using it immediately. Unplug your device during
lightning storms or when unused for long periods of time
Repairs: Do NOT attempt repairs. Do not attempt to take apart, open, service or
modify the devices hardware. Doing so could present the risk of electric shock
or other hazard. Any evidence of an attempt to open and/or modify the
device, including any peeling, puncturing or removal of any labels will void
the limited warranty
Environment: The device is designed for industrial indoor use only. Do not use outdoor or in
explosive environments
Cut hazard: Always handle optical fibers carefully and dispose fiber scraps in a suitable way

Transport and storage precautions
•The AUTOCLEAVER LDF™is a precision instrument and must be protected against humidity, vibrations and shock during
transportation and storage.
•When the machine is moved from a cold to warm environment, you should allow about an hour for acclimatization. By this
time, any condensation should have dissipated.
•Always transport the instrument in its original packaging materials, with its transportation safeties and with the marked
side up to prevent damage. Remove fiber handling parts that could come loose during transportation.
External care precautions
•Never use spray cleaner or compressed gas for cleaning the device.
•Never pour liquid cleaner on the instrument. Always put the cleaning solvent on to a clean applicator (i.e. clean, dry cloth
or applicator stick) first and then use the applicator to clean the exposed parts.
•Isopropyl alcohol (IPA) is the recommended cleaning solvent.
•Never use hard objects, acetone, thinner or benzene to clean the instrument.
Upon delivery
Unpacking
•Inspect box for damage prior to opening. If the box appears damaged, please notify the shipping company and NYFORS or
your eventual distributor as soon as possible.
•Remove all contents from the box and verify that all items are included.
•Save packaging material for future use.
Supplied in package

Flashing characteristics of the start button
A LED in the start button is used to indicate the status of the cleaver:
Green: Standby: Cleaver is ready to be used
Green: Busy: Wait until cleaver is ready
Green: Done: Press start button to continue/reset
Red: Error: Press start button to reset
Red: Fatal error: Disconnect power from cleaver and then
connect it again. If fault remains, contact your service
agent.
