COMBO DEMO EVENT Distributed NG-POP – dNG-POP


Context and objective

Demo Event – 28th April 2016 – Lannion – dNG-POP 2

■  KeyFMCaccess/aggrega.onnetworkrequirementsiden.fiedinCOMBO♦  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.ve1:experimentallydemonstratethefeasibilityofselectedstructuralFMCsolu.ons♦  Goal: assess, test and demonstrate the feasibility of a selected structural FMC solutions

proposed in the architectural work in COMBO

■  Objec.ve2:defineanddemonstratetheconceptofUniversalAccessGateway(UAG)intheNextGenera.onPointofPresence(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

■  Thedifferentaccessnetworktechnologies&accessgatewaythathavebeendevelopedtodemonstratethestructuralconvergenceinclude:♦  A WS-WDM-PON, WR-WDM-PON & DWDM-centric demonstration platform ♦  A platform for realizing a UAG

COMBO DEMO EVENT Distributed NG-POP – dNG-POP (1) WS-WDM-PON


■  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

Introduction to WS-WDM-PON system



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

CexPONfilter



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
