Projected PON Deployment
The Need for Interoperability TestingService providers increasingly employ multi-vendor strategies in the access
Allows best-of-breed selection, resiliency against roadmaps and changes in pricing modelsCommon in DSL, 1:1 fiberNew in PON – traditionally single-vendor infrastructures, not feasible for 2nd generation deployment -- ONT and OLT need to become multi-vendor interoperable
Triple play services require deep dive in interoperability testing for service quality Regulators require uniform, standards-based interfaces in some countriesCross-technology interop required on management layer when mixing access technologies like PON, DSL and EFM
Interoperability Scenarios
Access Interoperability Testing at EANTC
MPLS and Ethernet World Congress, Feb 2009Carrier Ethernet World Congress, Sept 2008
Ethernet OAM Interoperability
Focused on business services (1:1 fiber, FTTB/FTTH) so far12 router/switch plus 2 analyzer vendors participatedOutstanding level of support Implementations fully interoperable for the three basic services (CC, LT, LB)Added Remote Defect Indication tests
Mobile Backhaul Interoperability Requirements
Additional network services required:Clock synchronization – rapidly growing number of implementations for IEEE 1588v2TDM (E1) over packet – established marketATM over packet – established, small market with some functional interoperability issuesSynchronous Ethernet – rare, early implementations… and, of course, Quality of Service and high availability functions
Future PON Multi-vendor Interoperability Test Areas

SummaryIncreasingly complex FTTx design frameworks
Multiple services: Triple Play, Business, MobileBackhaulMultiple access technologiesAutomated management and control
Physical layer testing is matureLots of things to do for network, transport,application testing of FTTx architectures
