The DGE-550SX is designed for Gigabit fiber server connection. It plugs into your PC's PCI expansion slot, transfers data at 2000Mbps full duplex. The card runs Windows 95, 98, 2000, ME, XP, NT, NetWare and Linux, providing a server pipe for workstations to simultaneously access databases, send files and e-mail. This card provides a secure environment for bandwidth-demanding applications.
This card allows you to establish a secure fiber link for your server. The card serves well in high electromagnetic interference environments, providing a multi-mode fiber cable distance of up to 550m to the switch.
The card uses the Bus Master mode to transfer data directly to/from the host at multi-megabits per second, bypass the host CPU to alleviate its workload. Running at 1000Mbpsfull duplex, it provides the ideal speed for very fast server access from workstations.
The card provides on-board screening of VLANs Tagged Ethernet frames, allowing your server to be configured with a VLAN-supported switch. Consequently, your server can be part of a VLAN network, where domains are segmented up to enhance performance and security.
IP header and IP checksum of IP network packets are done by the chipset. In Internet, Windows and Unix environments, this serves well by offloading the host's overheads to enhance the network performance.
