Context and objective Key FMC access/aggrega.on network requirements iden.fied in COMBO ■ ♦ High capacity & longer reach (for site consolidation & converged access/ aggregation) ♦ Transparency (bit rate, protocol, wavelength (colorless plug & play ONUs)) ♦ Flexibility (programmable transport infrastructure for optimal use of transport resources) ■ Objec.ve 1: experimentally demonstrate the feasibility of selected structural FMC solu.ons ♦ Goal: assess, test and demonstrate the feasibility of a selected structural FMC solutions proposed in the architectural work in COMBO ■ Objec.ve 2: define and demonstrate the concept of Universal Access Gateway (UAG) in the Next Genera.on Point of Presence (NG-PoP) ♦ Goal: bring UAG demonstration activities together into one collaborative effort, supporting partners to instantiate different VMs to support several functional entities of the functional and structural convergence activities ■ The different access network technologies & access gateway that have been developed to demonstrate the structural convergence include: ♦ A WS-WDM-PON, WR-WDM-PON & DWDM-centric demonstration platform ♦ A platform for realizing a UAG Demo Event – 28th April 2016 – Lannion – dNG-POP 2 This presentation is property of the COMBO Consortium and shall not be distributed or reproduced without the formal approval of the Project Board

Introduction to WS-WDM-PON system ■ GPON is presently being deployed in Europe for residential Access, but: ♦ GPON capacity is limited for future bandwidth needs • GPON is TDM based • Aggregated capacity of 2.5G/1.25G in DS/US • Typical splitting ratio of 1:32/1:64 ■ PON´s may be used for more than Access to residentials ♦ Business customers ♦ Mobile BS backhaul and fronthaul ♦ DSL backhaul ■ Need for WDM-PON systems capable for co-existence with current GPON deployments ♦ Wavelength Selective WDM-PON: WS-WDM-PON Demo Event – 28th April 2016 – Lannion – dNG-POP 5 This presentation is property of the COMBO Consortium and shall not be distributed or reproduced without the formal approval of the Project Board
WS-WDM-PON & GPON co-existence ■ WDM-PON is the choice to increase PONs capacity in Key FMC access/aggregation network identified in COMBO ■ WS-WDM-PON concept: Aggregation of WDM channels over a GPON deployment based on power splitters ■ Co-existence of GPON & WDM-PON is not trivial ♦ High Power Budget due to power splitter insertion loss • About 33dB for 1:32 splitting ratio and 18km ODN ♦ Need for tunable transmitter and receiver optics at ONU for colorless operation ♦ Need for sofisticated Control Plane algorithms to dynamically manage the ONU tunability and wavelength operation • Deployment is based on power splitters, no filters (e. g. AWGs) in the field Demo Event – 28th April 2016 – Lannion – dNG-POP 6 This presentation is property of the COMBO Consortium and shall not be distributed or reproduced without the formal approval of the Project Board

WS-WDM-PON Architecture – Control Plane ■ Out-of-band management ♦ ONUs start-up • Each new optical termination needs to know the available channels • Once the communication via dedicated US/DS wavelength channels has started ◊ wavelength negotiation • Implement an access to the medium protocol to avoid collisions between new ONUs • The control wavelengths are divided into sub-bands (one for each potential C-Band channel to be occupied by a WDM client) • Once the wavelength allocation is achieved ◊ Switch to In-band wavelength system ■ In-band management ♦ Control data is encapsulated inside Ethernet headers within each wavelength channel ♦ Change requests are considered to initiate a new negotitation between OLT-ONU ♦ The supervision is constant ◊ if any issue is detected, the ONU will return to negotiation (Out-of-band) Demo Event – 28th April 2016 – Lannion – dNG-POP 8 This presentation is property of the COMBO Consortium and shall not be distributed or reproduced without the formal approval of the Project Board
