  Conclusions
Why Operators SHOULD be interested in FMC?
    Fixed                  FACT: Continuing trend for fixed phones replaced by mobile phones
   Operator                Strategy: Business growth via expanding services, lowering cost,
                          partnering with Mobile operator(s) and unified charging
(e.g. BT, Comcast, etc)

                           FACT: Lack of infrastructure capacity to carry increasing mobile
    Mobile                broadband traffic
   Operator                Strategy: Increasing network capacity while minimizing CapEx and OpEx
(e.g. Sprint, T-Mobile,
    Vodafone etc.)        by partnering with Fixed Operator(s) to offload mobile traffic and unified
                          charging

                           FACT: Higher OpEx to maintain parallel infrastructures for fixed and
  Integrated              mobile networks
   Operator                Strategy: Reducing the OpEx by combining the infrastructures to support
      (e.g. AT&T,
    Telifonica etc.)      both fixed and mobile access


                           FACT: Need to offer their services via different kinds of access
      MVNO                technologies
 (e.g. Google, Yahoo)      Strategy: Reaching to larger space of subscribers via partnership with
                          both fixed and mobile access networks

FMC Requirements to Mobile Backhaul (1/2)
   The new backhaul model must protect the investment already done in 2G
    and 3G with QoS assurance to support circuit switch voice.

   This new backhaul has to be prepared for the 4G evolution to the next
    generation ===> Investment will be amortized during several years.

   Operators are looking for a cost effective technology, with high speeds
    and with capacity & QoS support to enable interconnection with the
    present and the future equipments, which could set an all-IP scenario for
    multimedia services.


             LTE and WiMax can achieve
             download speeds of
             100Mb/s. The aggregate of
             N x 100Mb/s needs a high
             capacity backhaul.

FMC Requirements to Mobile Backhaul (2/2)
   In the new backhaul, there will be traffic from 2G/3G and from 4G (LTE/WiMAX).

   3G networks usually use the clock reference that travels through the E1-T1 to stay
    synchronized with the other elements of the network (they can use a GPS system
    also). For WiMAX and TD-LTE, timing synchronization are also needed to ensure
    frame synchronization among the neighbor-BSs.

   But with the new schema of the network, the new Ethernet-backhaul will require
    additional methods to maintain the clock reference and the delay limits, based on
    the QoS engineering or on special physical layers to extract the clock from the
    data stream (Synchronous Ethernet).

  Backhaul Over EPON Solution for FMC


  Conclusions
Backhaul over EPON Solution for FMC (1/2)
   xPON technology using Circuit Emulation Service (CES) starts to be used for
    mobile backhaul
   Backhaul over EPON CES and over EPON Native to bear E1/T1 services complies
    with jitter specifications defined in G.853 – similar to SDH that meeting BTS service
    transmission requirements

     Backhaul over EPON CES
     can fully meet the standard
     indices, with less E1
     downlink delay than that in
     backhaul over GPON
     Native.




                                              14
Backhaul over EPON Solution for FMC (2/2)
   High-precision frequency synchronization
        Adopts synchronization principle similar to SDH, via the network reference clock of
         EPON to input to OLT, then from OLT to ONU, where ONU maintain the frequency
         synchronization with the clock source
   High-precision time synchronization
        Synchronization interworking with the 1588 master clock carried by inputting 1
         PPS+TOD signals or through the FE/GE interfaces at the OLT side.
         Test result shown time synchronization between EPON OLT and ONU can be as precise
         as 0.1 us (100 ns), i.e. enough to sustain CDMA/TD-SCDMA BTS’s synchronization
         requirement, hence, no need for GPS and lower construction cost and reliability

   QoS of E1 over EPON
        EPON supports SLA, admission control and dynamic bandwidth resource allocation to
         guarantee QoS via the support of traffic classification, VLAN allocation and CoS features

   Ring Network Protection
        IEEE 802.3 EPON defines several protection modes including backbone optical fiber
         protection and full protection that modify EPON pt-to-mpt topology to support
         SDH/MSTP ring protection
