The Cable system
…just fibers into a duct!
The main user cable can contain
several ESFUs (Easy Strippable Fiber
Units), each of which may contain 1
to 12 optical fibers. Fibers are then
routed from the Riser Cable, through
a breakout window, when a customer
connection is required to be made.
The fibre units are protected by a
flame retardant LSOH outer sheath.

FTTx Solutions
The Stripping Tool safely cuts a breakout
window in the riser cable, providing access
to the fibres.
The selected fibre unit (ESFU) can be
extracted and cut. This operation is
performed some floors above the floor
where the customer is to be connected (up
to 25 m).
At the floor where the fibre connection is
requested, the ESFU that was cut on the
higher floor can now be easily extracted.
