Typical in-building network layout
1. Floor Distribution layout
Living units are grouped per floor or per floor-section in an access
point
2. Central Distribution LayoutAll living units are connected to one central point

Good solution for large buildings
(high rise) as you access fiber

Central distribution Layout versus FloorDistribution Layout
Floor distribution points make the initial installation cost higher
(homes passed) but strongly reduced on connecting customers
(homes connected) A central distribution point requires access to the riser at every
customer connected and will increase the amount of cable in the riser
At higher take rate a floor distribution architecture will be lower cost In smaller buildings a CDP architecture can be sufficient and most
effective
In greenfield/new-builds often the cable ducting from the basement to
the living unit exists

Building Infrastructure
FTTH in MDUs is in most cases the third network in the building after
COAX and UTP cabling.
Reduces the available space to deploy the network
We deal with a great variety of building infrastructures as there are no
standards on the infrastructure methodology
Working in an existing building generates disturbance

Riser Cable
Riser Cable is a mini-breakout cable
containing individually reinforced
fibers called pico-breakouts (750micron diameter)
Pico breakouts can be pulled
through a tube/pipe as theseelements are reinforced (Kevlar)
without requiring overtubing
Pull strength of pico-breakouts:
300N
6, 12, 24 Fiber cable available

Riser Cable
As cable is very compact
in size and very flexible
the cable can be pulledthrough almost all ducts
such that the requirement
of site surveys can be
reduced
Can be pre-connectorized
in a robust way (basement
side)

Riser Cable
Pulling back fiber
Allows fibers to be pulled back from the cable through a small
incision in the cable (5cm) over long lengths (>20m)

Premises to Floor
Requires NO splicing or cleaving of fibers in the customers premises
Switching of fiber/cable type possible No fiber overlength to be stored separately
Reduces the amount of time required to spent inside the customer
premises
Allows the installer/operator to use existing design-wall outlets

Drop wire
We offer:
Pico-breakout (Pre-connectorized)
Drop wire that can be installed using staples and having an extremebend-optimized fiber (G657B+) to allow installations around sharp
corners (on the wall applications) (Under Development)

IFDB-M
The IFDB-M was designed to
accommodate these micro-sheath
cable constructions (other cabledesigns possible as well)
The drop cables can be spliced to
the riser cables using fusion or
mechanical splices.
Ideal for conventional cabling
solutions in high rise buildings

We see a trend to integrate the function into a
design-faceplate environment
For this reason a pico-breakout drop cable
allows felxibility to integrate the cabling solution
into existing face plates using bend insensitive
fiber and factory connectorization

Benefits of
Brownfield Optimized
Small diameter of the cable for easy installation in risers/ducts
Very compact cable accessories (IFDB-S; IPSO; SPLX) and for this
reason ideal for Brownfield applications
The smallest drop cable (Pico-Breakout) on the market as horizontal
drop wire for pulling into existing tubes/ducts which might even be
occupied by COAX or twisted pair cables

Benefits of
Less Material and Reduced Installation Time
Can be pulled through small tubes/ducts using the pico-breakout
Kevlar as pulling element without the requirement to overtube the
drop fiber due to its reinforcements which allow the drop fiber to be
pulled
Reduced installation time by using pre-connectorized Mini- and
Pico-Breakout cables
Less Connectivity Points
Pullable pico-breakouts allow to save up to 2 connection point at the
cable incision at floor box or at the wall outlet and in the basement
compared to conventional MDU cabling techniques deployed by
major incumbents in Europe

Benefits of
Less Building/Premises Disturbance
Due to the easy installable cable and accessories, there is less need
to do site pre-audits
With pre-connectorized Pico-Breakout drop cables, we do not have
to splice a pigtail or install a field installable connector inside the
customer premises
