PLANET GT-1205A - Manual (Page 7)

Via the build-in DIP-switch, the GT-1205A can be configured as
3-Port Ethernet switch or 2-Port Redundant media converter.
With the 3-Port Switch mode, it can operate Store-and-Forward
mechanism with high performance, with the 2-Port redundant
mode, it provides rapid fiber redundancy of link for highly critical
Ethernet applications. The redundant-mode supports auto-
recover function. If the destination port of a packet is link down,
it forwards the packet to the other port of the backup pair.
As the GT-1205A 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 conversion installation is quite quick and easy by simple
plugging and playing feature.
With 1000Base-SX / LX SFP ports, the GT-1205A is with high
reliability and flexibility to extend the distance up to 550m,
10km, or longer. It depends on the 1000Base-SX / LX SFP
transceiver modules.
