SuperStack 3 Switch 4400 PWR provides power and data
to POE-capable phones, and data to PCs.
SuperStack 3 Switch 4400, with 100BASE-LX10 connections to a
local service provider, provides converged services to clients
within a 10km radius.
The SuperStack 3 Switch 4400 adds support for the
emerging IEEE 802.3ah Ethernet in First Mile over Point
to Point Fiber (EFMF) standard. This enables the reach
of Fast Ethernet over fiber to be extended to at least
10km, giving a cost effective solution for wide area
Ethernet distribution. Support for two EFMF links per
switch, or multiple EFMF links aggregated across a
stack of switches, enables a resilient and scalable solution
to be implemented. Combined with the Switch 4400s
powerful QoS, Traffic Shaping and Multicasting features,
the available uplink bandwidth can be intelligently
shared between users.
