Layer 3: Service layer • Determines end-‐user experience • Should-‐be: self-‐installable, powerful
Layer 1: Passive layer • Highest iniHal investment • Should be: Layer 2-‐agnosHc, future proof
Layer 2: Transport layer • Increasing amount of choices to deal with • Should be: cost-‐effecHve under growth

Fiber To The Home – Three Layers Exist

Open Access Network Business Models
• Open Access FTTH has different operators at each layer, namely:
• Passive Infrastructure Provider, e.g. Reggefiber, Stokab
• Network or Connection Provider, e.g. KPN-ITNS, Accione, GITpa, DST
• Service Provider, e.g. KPN, Tele2, Adamo, Orange

Matching The Gateway to Open Access
• An FTTH gateway solution consists of 3 modules: FTU, ONT, and RG
• What are some of the challenges in open access?
Layer 3: Service layer • FTTH CPE: ResidenHal Gateway • Service Provider • Lifecycle: 2-‐5 years
Layer 1: Passive layer • FTTH CPE: Fiber TerminaHon Unit • Passive Infrastructure Provider • Lifecycle : >20 years
Layer 2: Transport layer • FTTH CPE: OpHcal Network TerminaHon • Network/ConnecHon Provider • Lifecycle: 8-‐10 years

L1: Fiber termination unit
• The fiber termination unit (FTU) is the passive demarcation point
• Desktop placement of ONT using an optical patch cord
• Wall-mount “click-on” installation using fiber-splice solution
• Challenge: diversity of solutions in shape, size, and interface
• Also, fiber regulation is different per country

L2: Optical network termination
• Optical network termination (ONT) is the network demarcation point
• External residential gateway is remotely located or “click-on”
• Any transport layer is terminated: GPON, Ethernet PTP, WDM PON, …
• Challenge: How to separate responsibilities between NP and SP when ONT is integrated with RG?

L3: Residential Gateway
• The residential gateway (RG) is the service demarcation point
• A “one-box” solution: Integrated with the ONT, trending in USA
• A “click-on” module: Flexible service platform independent of the ONT
• Desktop gateway using patch cords
• Challenge: How to manage open access and diversity of bandwidth provisioning inside the home?

Example: Integrated FTTH Gateway
• The individual modules allow heterogeneity and facilitate change
• Each module can have a different owner with separated responsibility
• Modules can be changed independently of one and other
• Is this this open access gateway?

Management and Provisioning
• The ONT and RG are managed separately
• The ONT transports the data that is terminated at the RG
• Such separation of functionalities follows BBF TR-142 v2 (GPON)

Conclusions
• A three-module integrated CPE is a matched solution to FTTH
• A demarcation point in hardware for the open access operators
• Each module is optimized in functionality and managed independently
• A “click-on” RG allows user self-installation with reduced service calls
• Interoperability is a key requirement at all three FTTH layers
• In-home networks is a next domain to be conquered
