Adjustable DIP Switch for 100FX or 1000X SFP Module Selection
Via the built-in DIP switch on rear panel, the GT-1205A can be congured as supports 100BASE-FX SFP module or 1000BASE-X SFP module on its dual
SFP slots, the GT-1205A can be connected over fiber optic cabling at a distance extended from 550 meters to 2km (multi-mode fiber) to 10/20/40/80/120
kilometers (single-mode ber or WDM ber), using the PLANET MFB/MGB series 100/1000BASE-X SFP modules.
Adjustable 3-Port Switch Mode or 2 Fiber Port Redundant Mode
Via the built-in DIP switch, the GT-1205A can be configured as 3-port Ethernet switch or 2-port redundant media converter. In the 3-port switch mode, the
GT-1205A can operate in Store-and-Forward mechanism with high performance; on the other hand, when in the 2-port redundant mode, it provides rapid
ber redundancy of link for highly critical Ethernet applications. The redundant mode also supports auto-recovering function. If the destination port of a packet
is link-down, it will forward the packet to the other port of the backup pair.
Easy Deployment Standalone or with Chassis
The GT-1205A Gigabit Media Converter can be used as a standalone unit or as a slide-in module to the PLANET Media Converter Chassis, MC-700 and
MC-1500 chassis series. These media chassis can assist in providing DC power to the GT-1205A Gigabit Media Converter and the ber-optic network can be
maintained at one central location. With the 3-port switch mode, they work in high performance Store and Forward mechanism, and prevent packet loss with
IEEE 802.3x Flow Control (Full-duplex) and Back Pressure (Half-duplex) function.
Plug & Play Installation
As the GT-1205A Gigabit Media Converter fully complies with IEEE 802.3 10BASE-T, IEEE 802.3u 100BASE-TX/FX, IEEE 802.3ab 1000BASE-T and IEEE
802.3z 1000BASE-LX/SX, the Gigabit media conversion installation is quite quick and easy simply by using the plug and play feature.
