Industrial Applications

1. Industrial Enterprise Campus Fiber Aggregation

In large-scale manufacturing facilities or distributed enterprise campuses requiring high-speed data transmission over long distances, this switch acts as a localized aggregation hub. Using its 12 independent Gigabit SFP ports, it consolidates dedicated single-mode optical lines coming from various remote production buildings or warehouse terminals.

Problem Solved

Overcomes the 100-meter physical length limit of standard copper cabling while ensuring complete galvanic isolation and high-speed network performance, backed by L3 static routing to partition logical traffic locally.

2. Smart Campus Video Surveillance Distribution

In security-dense environments such as campuses or retail parks, the switch coordinates video feeds from distant IP security cameras. Local cameras plug directly into the 8 Gigabit RJ45 copper ports, while distant perimeter cameras connect via SFP optical modules on the remaining 12 fiber interfaces.

Problem Solved

Eliminates network congestion and screen stuttering by utilizing IGMP Snooping and QoS SP/WRR queue scheduling to guarantee packet prioritization and prevent massive video multicast streams from saturating unrelated network nodes.

3. Factory Floor Control Room Segregation

Positioned inside an main instrumentation cabinet, this L3 switch connects administrative office networks with ruggedized factory floor PLC networks. Utilizing its onboard DHCP Server and RIP dynamic routing, it automatically provisions and partitions local automation subnets.

Problem Solved

Protects industrial machinery control loops from being crippled by broadcast storms generated on administrative lines, while using IP-MAC-Port-VID binding and DoS protections to block unauthorized hardware modifications.
