2. Overview: About the PoE, PoE+ 10/100/1000 Media Converters
The PoE, PoE+ 10/100/1000 Media Converters are solutions for private
network applications that require power over Ethernet for locations inside
buildings where PoE is required to power an Ethernet device. The LGC5200
Series offer one SFP or fixed fiber transceiver, 1x9, uplink for the network
connection, one PSE 10/100/1000Base-T copper port that provides Power-
over-Ethernet (IEEE802.3af), and one 10/100/1000Mbps copper port. The
LGC5210 Series offer one SFP or fixed fiber transceiver, 1x9, uplink for the
network connection, and two PSE 10/100/1000Base-T copper ports that
provides Power-over-Ethernet (IEEE802.3af).
As a fiber-fed demarcation unit, PoE, PoE+ 10/100/1000 Media Converters
provide both power and data to a remote device over a standard CAT5
copper line, eliminating the need for a power connection to the remote
device. The LGC5200 series provisions up to 15.4 watts on one copper port,
and can be powered by an external AC adapter or DC terminal block. The
LGC5210 Series provides up to 25.5W per copper port.
The SFP uplink can support fiber or copper SFPs. The fiber SFP, available
in SC or LC connectors, supports 100FDX or 1000FDX; a copper SFP
supports the SGMII interface (10/100/1000Mbps). The SFP must be MSA-
compliant.
The copper ports auto negotiate to the connected device’s speed and duplex
mode: 10 Mbps, 100 Mbps or 1000 Mbps, and HDX or FDX (including Flow
Control). The PoE, PoE+ 10/100/1000 Media Converters support jumbo
frames up to 10240.
NOTE
Unless noted otherwise, any reference is applicable for both the 1x9 and SFP versions
of the PoE, PoE+ 10/100/1000 Media Converters in this manual.
