5. 5 Universal Etherent Access
6. 6 Two Access Network Paradigms The journey towards a true broadband society has started, with broadband penetration growing day by day.
But will the current path operators are traveling on allow them to achieve this kind of society? Will operators find a way to a profitable broadband destination, if they continue in the current direction?
We believe that it’s time to make a choice.The journey towards a true broadband society has started, with broadband penetration growing day by day.

9. 9 Ethernet – Universal Communications Outlet Service independent interface
Bandwidth independent interface
10. 10 What’s the optimal Access Medium? Optical fiber provides:
High (unlimited) bandwidth
Long reach
High quality transmission
Resilience to interference
EFM defines optical access:
Point to point
Point to Multipoint (PON)

14. 14 EFM Copper - Short Reach 10PASS-TS Business and Residential access over existing copper loops.
Existing (Cat-3) copper loops with POTS left unaffected.
Reach for Ethernet over copper increased up to 750m.
Ethernet Speed – minimum 10Mbps symmetrical
Based on VDSL (DMT) line-code
Typical applications: MTU/MDU service distribution, intra-campus connectivity
15. 15 EFM Copper - Long Reach2BASE-TL Ethernet access across the serving area
Reach for Ethernet over copper increased at least to 2700m (could extend up to 6km)
Symmetrical bandwidth – from 2Mbps up to 45Mbps
Based on Extended SHDSL (ITU-T G.991.2. rev. 2)
Enabler for consolidation of disturbing E1/T1/HDSL sources
Typical applications: service delivery from CO, DSLAM backhaul, cellular/WiFi backhaul

27. 27 EFMCu – Optimal Bonding for Ethernet Services
28. 28 EFM and Systems Implementation EFM defines an Interface, not a System
Some system level considerations are beyond the scope of EFM:
Ease of deployment / maintenance
High performance
Scalability
Carrier grade robustness (99.999% service availability)
The above issues can be addressed by:
Verify MEF-endorsed Certification
Specific system architecture
EFM vendor-specific extensions
