4 Port Fiberhome IBAS 110A , ESD2 Ethernet Switch Fiber Network Interface Card Supports VLAN Setting

4 Port Fiberhome IBAS 110A , ESD2 Ethernet Switch Fiber Network Interface Card Supports VLAN Setting 

The card can be divided into two types, electrical interface type and optical
interface type.

• The optical interface type of the ESD2 card has four Ethernet optical interfaces,
• TX1 / RX1 to TX4 / RX4.
• The electrical interface type of the ESD2 card has four Ethernet electrical
• interfaces, CH1 to CH4.

The main functions of the ESD2 card include

• It provides four FE optical / electrical interfaces (LAN port) externally and eight
• FE full-duplex data interfaces (WAN port) internally.
• It provides four working modes: 10Mbit/s half-duplex, 10Mbit/s full-duplex,
• 100Mbit/s half-duplex, 100Mbit/s full-duplex. Any specific working mode can
• be chosen through the interface auto-negotiation and switched according to
• specified requirements.
• It supports GFP or WRI encapsulation with a minimum cross-connect
• granularity of VC-12.
• It supports backpressure flow control under half-duplex mode.
• It supports IEEE 802.3x flow control under full-duplex mode.
• It supports VLAN setting based on IEEE802.1Q and interfaces.
• It supports bandwidth limit and QoS functions.
• It performs port trunking functions.
• It supports remote online upgrading of FPGA and BCT software.
