4500 Series line cards for
delivering Ethernet in the First Mile (EFM)
fulfill the high-density, high-bandwidth,
and long-reach requirements that network
operators have to build the next generation
of metropolitan-area access networks.
Cisco Catalyst 4500 Series EFM line cards
(Figure 1) let service providers deliver any
combination of data, voice, and video
services over a single optical connection to
residential homes, business parks, and
multitenant units.
Cisco Catalyst 4500 Series EFM line cards
are also appropriate for manufacturing
facilities, transportation monitoring, and
fiber-to-the-desktop applications.
Ethernet over fiber enables operation in
noisy electromagnetic environments,
providing physical security and longer
reaches with the same well-understood
Ethernet transport.
Cisco Catalyst 4500 Series EFM line cards
are the industry’s highest-density line cards
for optical Fast Ethernet and Gigabit
Ethernet with full support of IEEE 802.3
standards for Ethernet over fiber. The
Cisco Catalyst 4500 Series line cards are
designed with functional transparency that
allows full integration with the supervisor
engine’s capabilities to increase deployment
lifetime. New capabilities are delivered to
each line card port simply by swapping the
supervisor engine.  Cisco Catalyst 4500
Series switches deployed with the
Cisco Catalyst 4000/4500 Supervisor
Engine 4 offer quality of service,
sophisticated traffic management,
and comprehensive security.
