D-LINK DGE-550SX Network Adapter Fiber 1000BASE-SX PCI Card SC Gigabit Ethernet

D-LINK DGE-550SX Network Adapter Fiber 1000BASE-SX PCI Card SC Gigabit Ethernet

DGE-550SX adapter with optical Gigabit Ethernet interface is designed to connect to servers. It is compatible with 32-bit bus PCI, provides data transfer rates of 1 Gbit / s in full duplex mode, and supports VLAN filtering and hardware checksum computation protocols TCP / UDP / IP. The adapter works with Windows 95, 98, 2000, ME, XP, NT, NetWare, and Linux, allowing workstations access channel to the server to simultaneously access databases and send e-mails.

Reliable fiber connection
The adapter allows you to establish a reliable connection to the server via an optical link. It works well in environments with high electromagnetic interference, providing a multimode fiber optic cable to connect to the switch, located at a distance of 550 m.

High performance
The adapter uses the Bus Master mode to directly communicate with the system to bypass multimegabitnoy speed CPU, thereby relieving him. Working at a speed of 1 Gbit / s in full duplex mode, it provides the ideal speed for quick workstation to access the server.

Flow control to minimize packet loss
The adapter supports flow control, IEEE 802.3x Flow Control, allowing servers to directly connect to the Gigabit Ethernet switch for fast, reliable data transmission in full duplex mode. The adapter monitors the buffer switch port, and if it starts to overflow, temporarily stops the transmission to prevent data loss, betray network

VLAN to improve performance and reliability
AC adapter has a built-in filtering of tagged Ethernet-frame VLAN, allowing the server to be configured to support VLAN. This allows the server to work in a flexible and secure network, established in accordance with the standards.

Hardware calculation of IP headers and IP checksums
Hardware calculation headers and checksums IP-packets offloads the CPU of network nodes and increase network performance.
