In the Extend operation mode, the FGSD/FGSW 802.3at PoE+ Switch series
operates on a per-port basis at 10Mbps duplex operation but can support 20-
watt PoE power output over a distance of up to 250 meters overcoming the 100m
limit on Ethernet UTP cable. With this brand-new feature, the FGSD/FGSW Series
provides an additional solution for 802.3af/at PoE distance extension, thus saving
the cost of Ethernet cable installation. Its VLAN isolation function isolates ports so
as to prevent broadcast storm and defend DHCP spoong in the Extend operation
mode.

Flexible Extension Solution
The two mini-GBIC slots built in the FGSD/FGSW 802.3at PoE+ Switch series
are compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable)
ber transceiver, uplinked to the backbone switch and monitoring center in long
distance. The distance can be extended from 550 meters (multi-mode ber) to
10/20/30/40/50/60/70/120 kilometers (single-mode ber or WDM ber). They are
well suited for applications within the enterprise data centers and distributions.
