Department / Edge Security and QoS Switch for SMB The WGSD-8020 connects up to 8 high speed workstations in the Ethernet environment, in which its two SFP Mini-GBIC interfaces uplink to a department backbone. Moreover, the Switch provides 16 Gigabit per second switch fabric and high bandwidth for backbone connection. The WGSD-8020 improves the network efficiency and protects the network clients with the powerful features: 　　• IPv6 / IPv4 management 　　• Layer 2 to Layer 4 security 　　• QoS 　　• 802.1x Port-Based and MAC-Based network access authentication security 　　• Multicast IGMP Snooping The advanced functionality of the WGSD-8020 eliminates traditional issues associated with the use of Ethernet. Users can be separated with advanced VLAN functionality to enhance security. It makes the WGSD-8020 one of the best and most cost-effective switch solutions for SMB. FTTX / MAN application Switch The WGSD-8020 applies the double tag VLAN (Q-in-Q) technology to provide low cost and easy operation for service providers carrying traffic for multiple customers across their networks. It features SNMPv3 and RMON Groups. The SNMPv3 security structure consists of security models, with each model having its own security levels. With two Dual-Speed SFP slots built in, the deployment distance of the WGSD-8020 can be extended from 550 meters (Multi-mode fiber) up to above 10/50/70/120 kilometers (Single-mode fiber), which provides a high-performance edge service for FTTx solutions. To build a network solution of FTTH (Fiber to the Home) or FTTC (Fiber to the Curb) for ISPs and FTTB (Fiber to the Building) for enterprises, the various distances of SFP (small-form factor) and Bidi (WDM) transceivers are optional for customers’ choices. For security and various applications, the 8 Gigabit ports of the WGSD-8020 can be configured with VLAN settings and connect to different units, offices, flowers, houses and departments.
