Draka BB-XS (G. 657A2&B2) 6

Bend insensitive single-mode-fiber - G.657.A2 BIF SMF with min. specified radius of 7,5 to 10mm is well suitable for all demanding access requirements - G.657.B2&B3 BIF SMF are not necessarily compatible with the standard G.652 family due to Japanese low MFD specification, which is part of these sub-categories. G.657.B2 fibers already perform very well in-building applications (G.657.B3 is not necessary) - BendBright-XS(fulfilling G.657.A2&B2)is today the perfect match for access as well inbuilding,allowing end-to-end solutions. - Bending radius of 7.5mm is feasible and do not affect the lifetime. - Draka‘ s BendBright-Elite offers G.657.B3 specification (min. bending radius 5mm) with enlarged proof test of 2% for better lifetime protection of this fiber type. 7

Our Fiber Solution

BendBright-XS value proposition –  100x less sensitive to bending losses –  Fully compatible with G.652.D / ESMF –  Lowest total installation cost for operator –  Allows use of smaller ONT, patch panels etc.

Operators already deploying BendBright-XS: AT&T, France Telecom, Telefonica 8

FTTH

Definitions / What Is FTTx? FTTH – Fiber to the Home FTTB – Fiber to the Building / Basement (not included FTTO) FTTC – Fiber to the Curb (last distribution point / node) FTTN – Fiber to the Node –  A fiber based system in which the optical network unit is located in a node that may serve 50 to 500 homes. The distinction between FTTN and FTTC is the number of homes used by the optical unit. For FTTC the number typically range from 4 to 32.

FTTP – Fiber to the Premises

– Similar to FTTH but more inclusive – the subscriber premises may be retail or other small businesses as well as residential customers. FTTx – Refers to FTTB, FTTC, FTTN and FTTP

Key Drivers Globally, bandwidth demand continues to accelerate driven by quadruple play (voice, video, data & wireless). –  Regional development varies but long-term global developments are evident. –  Access development will eventually drive growth in long-lines as the pipes fill. –  New services ultimately require fiber based infrastructure. Some will migrate to FTTH, others will evolve into hybrid systems. More bandwidth capability will be the driver.

19

Key Drivers Economics are critical, returns on investments are under scrutiny. –  Service providers and network operators must improve on the current returns in order to justify future development. •  Value proposition to the subscriber is the critical element. –  CAPEX and OPEX costs must come down to support the consumer driven economic model. •  GDP growth needs to continue. Inflation has to be kept in check. –  High inflation / recession will have a high impact on development. –  Content convergence will force industry consolidations. –  The case for winners and losers is still developing

20

Key Drivers Political issues are significant – Legacy PTT’s are fighting the EU open market tactic, which stalls FTTx development. – Protectionism in lieu of open competition is the landscape and the open market is winning. – State and local regulators can open and close access to FTTx in the United States

21

Key Drivers Regulation Policies • 

Consumer Protection

Business Protection

• 

• 

• 

Investment Protection

US –  August 2003 Terennial Review Order basically bundles FTTx elements. –  Video is a local (state) issue. Europe –  Broadband roll out just started after liberalization in 1998. –  Players ask for investment protection, mainly DT in Germany. –  EU wants to keep business protection and as a result traditional Telco’s don’t move. Middle East –  Investment protection, wealthy parties control the game. Asia Pacific –  Consumer protection. –  Heavy push on fiber investments due to dense population.

22

Key Drivers The customers are changing – Video content will drive who will play. Voice has become the “lost leader”. – In EMEA, legacy PTT’s are standing on the side lines while new independents step in. Old relationships become less meaningful.

23

Key Drivers Competition varies – Some competitors provide total solutions, others specialize in key components – All propositions will varie from region to region.

splitters

G-PON technology (class C+) 2 splitters (PLC technology) with 1:128 total splitting ratio 30

FTTH : the most promising approach using indoor existing infrastructures   Basement box: it contains the secondary preconnectorized splitter of the PON and it is installed in the basement   Vertical rise: cabled with a multi-fiber cable or singlefiber cables (small buildings, maintenance) using the existing ducts. The cables can be connectorized at the box side end in the factory or in the field (by means of fusion type or mechanical connectors)   Fiber extraction at floor: all the required fibers are extracted at each floor and are protected with a suitable system

Extraction and/or Termination at the floor Connection to the flat

Single-fiber cable

Vertical rise

or Multi-fiber cable Box at the building basement

Customer connection: it is performed “on demand”, splicing a single-fiber cable, installed in the horizontal path, with the extracted fiber (if multi-fiber cable solution is used in the vertical rise); the splice has to be properly protected and inserted in the customer existing tube. When single-fiber cable is used for the vertical cabling, the customer is directly connected from the basement box without splices. At the user end the customer drop is connectorized, in the factory or in the field, and installed in the outlet.

Fibers are extracted from the cable for customer connection through a splice with the customer cable Suitable protection must be used at the extraction and splicing points when sharing of infrastructure with other services can be dangerous

Floor (n)

-suitable for high count customers buildings -must be flexible and robust

32

Single-fiber cables: -it consists in a reinforced structure containing one (or more) fiber (G.657A type) -maximum size 2 mm, compatible with the small size of the existing customers tubes -suitable for medium-small size buildings -it can reach customer directly from the basement box or from the extraction point of the multi-fiber cable at the floor level -suitable for installation in very tortuous and congested paths in which tension, bending and compression can reach very high level -the external sheath compound shows low friction properties
