Specification :
12F+ 12 high-performance smart Layer 2 optical Ethernet switch provides an ideal solution for fiber-to-the-home ( FTTH) and fiber-to-the-desk ( FTTD) , and for the applications where the environmental conditions exceed the reach of CAT5 copper cable. It offers a mixture of twelve 100Base-FX ports and twelve 10/ 100Base-TX ports. The standard design with a 19-inch rack-mount width and a 1U height gives the highest port density ( SC connectors) of optical Ethernet switches on the market. 12F+ 12 manual-driven configuration console allows administrators to easily setup the switch using a standard RS-232 port.
Features
 Non-blocking store-and-forward shared-memory architecture with a 4.8Gbps switching
capacity and an efficient self-learning and address recognition mechanism enables the
forwarding rate to proceed at a full wire speed.
 A mixture configuration of copper and fiber ports to meet the requirement of various
applications, such as FTTx, optical LAN, Ethernet based DCS and security surveillant
system, etc..
 6K address table for auto-learned unicast or static unicast/ multicast addresses.
 7 trunk groups of up to 4 member ports within 24 ports with flexible load distribution
control and fail-over function.
 Static priority and 802.1p Class of Service with 2-level priority.
 802.3x flow control for a full-duplex mode and collision-based backpressure for a
half-duplex mode.
 Port-based VLAN and 802.1Q tag-based VLAN with 255 VLAN groups.
 Head of Line ( HOL) blocking prevention
 Broadcast storm filtering.
Network Management
