2G + 24SFP Management Gigabit Fiber Switch
2G + 24SFP Management Gigabit Fiber Switch Overview
The LNK-FS242 is a high-performance Layer 2/Layer 4 managed gigabit fibre switch designed for
robust and secure network aggregation. It features 24 1000 Mbps SFP optical ports for flexible fibre
connectivity and 2x 10/100/1000 Mbps RJ45 ports for copper uplinks. It supports hardware-based wire-speed
switching for non-blocking performance. The switch offers comprehensive management via an intuitive
web interface, allowing advanced features to be easily configured. Built for security, it features an integrated
ARP and DOS defence system to mitigate virus attacks and network threats. With powerful tools including
QoS, Spanning Tree Protocol (STP), storm suppression, bandwidth control, IGMP snooping, access
control lists (ACLs) and DHCP snooping, the LNK-FS242 is an ideal, reliable solution for small and
medium-sized enterprises, campus networks and metropolitan area networks (MANs).
Unmanaged 24-Port SC Fiber Switch Features
►802.1x authentication support for secure user access control
►Wire-speed forwarding with non-blocking switching architecture for maximum performance
►Advanced port management functions, including port mirroring, port aggregation, and port speed limiting
►Flexible VLAN support, including port-based VLAN and IEEE 802.1Q VLAN tagging
►Storm control for broadcast, multicast, and unknown unicast (DLF) traffic to ensure network stability
►Spanning Tree Protocol (STP) support: IEEE 802.1d, IEEE 802.1w (Rapid STP), and IEEE 802.1s (Multiple STP)
for loop prevention and reliable network redundancy
