Zhone has integrated both copper and fi ber access into a
single access chassis, serving gigabit Ethernet and bonded
copper in one platform for business access.
Aktino AK5000 Aktino builds a proprietary physical layer that focuses on
crosstalk mitigation. While not a standards-based EFM
product, it does leverage some of the encapsulation techniques
defi ned in Ethernet access standards.

As this migration evolves, all DSLAMs will eventually support
the EFM technologies discussed in this section for residential
as well as business services.
