OnAccess 1101 Optical Gigabit Ethernet adapter is designed to operate at 1,000Mbps at full duplex. It supports IEEE 802.1p Traffic Prioritization for time-sensitive and mission-critical traffic. With IEEE 802.1Q multiple VLAN support, it provides VLAN tables that can filter packets by recognized VLAN tags. It provides IEEE802.3x Flow Control Enhancements, which are needed for a network adapter to function with a switch. In full-duplex mode, MAC implements the PAUSE control function.Features and specifications: 1) Hardware VLAN filtering. 2) Chip-level Internet Protocol (CLIP) for IP packet processing3) IEEE 802.3z compliant4) Complies with the PCI v2.2 interface standard - supporting operation at 33/66MHz and 32/64 bit wide data path5) Full duplex or half-duplex operation6) On-board verification of IP header and TCP/UDP checksum7) On-board screening of VLAN-tagged packets - tagged in compliance with IEEE 802.3ac 8) IEEE 802.3z 1000Base-SX, 1000Base-LX gigabit Ethernet compliant9) Standard optical fiber connector and cable type options10) Transceiver lasers compliant with laser AEL Class 1 standards and is safe for eye-viewing11) Plug and play installation12) Two LED indicators: Link/RxAct, Power/TxAct13) Drivers for all leading network operating systems, support for: a) Windows XP b) Windows 2000 c) Windows 95 OSR2, 98, 98 SE d) Windows NT 4.0 e) Windows ME f) Novell Netware Server 4.x, 5.x , 6 g) Novell Netware Client32 for DOS h) Linux (kernel 2.4.x) 14) Network type: optical Ethernet 1000Base-SX/1000Base-LX a) Single single-mode fiber / dual wavelength 1,310 / 1,550nm, maximum reaching 20km b) Dual single-mode fiber / single wavelength 1,310nm or 1,550nm, maximum reaching 80km c) Dual multimode fiber / single wavelength 850nm, accepts 62.5 / 125 micron multi-mode fiber optic cable for a maximum length of 260 meters, accepts 50 / 125 micron multi-mode fiber optic cable for a maximum length of 550 meters15) Host interface: PCI 2.1 Bus (Bus Master)16) Physical dimensions: 165mm x 66cm 17) Power consumption: 5W max.
