1 INTRODUCTION
OVERVIEW
This device is an intelligent Layer 3 switch designed for delivering Fiber-To-The-
Home (FTTH) high-speed Internet access. It can provide first or second level
aggregation of fiber optic nodes. When functioning as a lower level aggregation
device, it supports up to 24 subscribers through SFP fiber optic downlink
connections to the customer’s premises equipment (CPE).
The switch provides two 10 Gigabit XFP slots for uplink connections to the
Central Office (CO), or for downlinks to other network aggregation devices.
The switch has one 10/100BASE-TX port for dedicated management access,
which can be operated outside the data channel. It has an SNMP-based
management agent embedded on the main board, which supports both in-band
and out-of-band access using a Web browser, SNMP/RMON, or Telnet/SSH.

SWITCH ARCHITECTURE
This switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all
ports. The switch also features full-duplex capability on all ports, which
effectively doubles the bandwidth of each connection.
