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
