Gigabit Networking with Energy Savings
In line with the energy-saving trend worldwide, PLANET has delivered a new-
generation Gigabit Networking PoE PD Media Converter, GT-805A-PD. The GT-
805A-PD incorporates the following advanced concepts:
■ IEEE 802.3af/at/bt 48V~54V DC in-line power input
■ Easy to install and use
■ Compact-sized design
■ Simple troubleshooting
PLANET GT-805A-PD is an 802.3at PoE+ PD 10/100/1000BASE-T to
100/1000BASE-X SFP Media Converter equipped with a convenient and cost-
effective 802.3af/at/bt PoE power injection solution. It is quite different from the
earlier version of PLANET media converter family that needs to obtain power
from DC power adapter; it can power on via various IEEE 802.3at/bt PoE PSE
equipment.

TwoKindsofPowerInputDesignsforFlexibleInstallation
The GT-805A-PD features two kinds of power input system designs (IEEE 802.3af/
at/bt 48V~54V DC in-line power and optional 5V DC input) incorporated into
customer’s network to enhance system reliability and uptime. However, that has to
depend on the kind of Ethernet environment that is needed, be it the GT-805A-PD
operated as a PoE PD media converter or standard Gigabit media converter with
optional 5V DC input.
