Overview
The AT-PC2002/POE Media Converter is a simple and reliable way to
connect Fast or Gigabit Ethernet devices across large geographical
distances with fiber optic cable. The unit has one 10/100/1000Base-T
twisted pair port for a local connection and one slot for a fiber optic
100Base-FX or 1000Base-X SFP module. The product features Power
over Ethernet (PoE) on the twisted pair port for support of a Powered
Device (PD), such as a wireless access point or a Voice over Internet
Protocol (VoIP) telephone.
This unmanaged product is suitable for the central office or a remote site
and can be installed on a table or a wall. LEDs on the front panel display
the general status of the unit and the ports, and DIP switches on the back
panel let you configure the port settings.
The product features low latency to minimize the impact on network
performance along with cyclic redundancy check (CRC) detection to
prevent the propagation of incomplete or fragmented packets on your
network.
