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. 
Two Kinds of Power Input Designs for Flexible Installation
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.
High Performance and Steady Network Communications Guaranteed Despite Distance Extension
The GT-805A-PD extends communication distance with high Gigabit performance via SFP slot and SFP transceiver. The GT-805A-PD provides media conversion between 10/100/1000BASE-T and 1000BASE-SX/LX interfaces for various fiber optic applications. The available SFP LC fiber interfaces are shown below:
| Optic Mode | Connector Type | Distance |
| Multi-mode | Duplex LC | 220m/550m/2km |
| Single mode | Duplex LC | 20/40/80/120km |
| Single mode WDM | Simplex LC | 2/10/20/40/80/120km |
Enhanced Smart Management Features
The GT-805A-PD provides auto MDI/MDI-X on its TP port and the DIP switch to configure the Link Fault Passthrough function (LFP). The LFP function includes the Link Loss Carry Forward (LLCF)/Link Loss Return (LLR). LLCF/LLR can immediately alert administrators of the problem of the link media and provide efficient solution to monitoring the network. The DIP switch can disable or enable the LFP function.
- LLCF means when a device connected to the converter and the TP line loses the link, the converter’s fiber will disconnect the link of transmission.
- LLR (Link Loss Return) means when a device connected to the converter and the fiber line loses the link, the converter’s fiber will disconnect the link of transmission.
Both can immediately alert administrators of the problem of the link media and provide efficient solution to monitoring the network.
Can be Easily Deployed as Standalone Unit or with Chassis
The GT-805A-PD allows two types of the segment to connect easily. The GT-805A-PD can be used as a standalone unit when powered by its DC adapter or used as a slide-in module to PLANET 19-inch 7-/15-slot media converter chassis (MC-700/MC-1500/MC-1500R/MC-1500R48). These media chassis can assist in producing the power for the GT-805A-PD to maintain the fiber-optic network at one location. As the Gigabit media converter fully complies with IEEE 802.3 10BASE-T, IEEE 802.3u 100BASE-TX, IEEE 802.3ab 1000BASE-T and IEEE 802.3z 1000BASE-LX/SX, the Gigabit media converter installation is quite quick and easy with its Plug and Play feature. The GT-805A-PD also supports flow control and back pressure in half-duplex mode to eliminate packet loss.
