1. General Information
The V2 is a unique device designed for the installation of fiber optic cables directly into ducts. The
V2 consists of a duct clamp and a belt drive system, which, when combined, installs a cable into an
airtight duct at speeds ranging from 0-200 m/min.
The V2 comes equipped with an LCD display as standard. The machine should be complemented with
specified duct clamps, cable seals, and cable guides depending on the dimensions of the duct and
cable for installation.
This user manual provides a comprehensive description of the V2, designed to feed fiber optic cable
through ducts. The duct must have been previously installed underground or above ground to receive
the fiber optic cable and must be suciently long at the outlet to be received by the machine. The
duct must be made of material with adequate pressure resistance to be tightly sealed in the machine’s
duct clamps. The duct should be airtight up to a pressure of 16 bar. Duct sizes range from 7 mm-50
mm, while fiber optic cables range from 2.4 mm-16 mm.
The V2 consists of a duct clamp manufactured in two halves that clamp around the duct. The duct
clamp holds a seal through which the fiber optic cable is fed before entering the duct. The duct
clamp and cable seals can be replaced to accommodate dierent duct and cable sizes. The duct is
mechanically clamped between the clamps, preventing movement in all directions. Seals fit around the
duct when clamped securely.
The fiber optic cable is fed through the duct with a combined pulling/pushing force. The pulling force
is achieved when pressurized air is fed into the duct clamp and forced into the duct, generating
resistance on the fiber cable from the airflow passing over it. The pushing force is created by engaging
the belt drive system. As the belt drive system feeds the fiber cable into the duct, pulling force is
generated by the airflow. The fiber optic cable floats inside the duct, minimizing resistance to being
pushed in by the belt drive.
The use of the V2 for operations other than those described in this manual is considered hazardous
and is discouraged. The manufacturer is relieved of any responsibility, civil or criminal, for the use of this
machine for purposes other than intended. The manufacturer’s responsibility ceases, and the warranty
becomes void when any of the following occur:
A. When the V2 is used for purposes other than described in this manual.
B. Modifications and/or alterations are made without written approval from the manufacturer.
C. Non-use of original manufacturer parts.
D. Poor maintenance.
E. Failure to use provided safety devices or equipment.
F. Connection of this device to machines and/or parts that have not been manufactured or
approved in writing by the manufacturer.
G. The V2 should not be used to install any cable other than fiber optic cable specified within the
range outlined in this user manual.
H. The V2 must not operate without oil in the oil reservoir, immediately voiding the warranty.
I. Check the oil level in the reservoir daily.
Jetting AB is not responsible for damages resulting from improper use of the V2.
