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

Conventional cabling solution

Allows very fast access to fiber

bundles inside the micro-sheath

cable Reduces the installation time of the

distribution box

Keeps mechanical integrity of thecable (no cut of strength members

required)

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


21/37

May 28, 2009page 21 /

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)

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

feeder cable(s).

Typical products are FIST-GB2 and FIST-MB2 boxes Both spliced and connectorized solutions possible with the possibility

to integrate splitters in case of PON architectures

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

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

Current CPWO and HFTP

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


36/37

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


37/37

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
