OMS-RJ45/16/1000,OMS-RJ45/24/1000,16ch/24ch,CAT5E/CAT6 Gigabit Network Surge Protectors for network switches, routers, industrial Ethernet and other network communication links.
Product Overview
OMRDON 16-port/24-port Rackmount Network Surge Protector (SPD) is a high-performance lightning protection device designed for Gigabit Ethernet (100/1000Mbps), which can be installed in a 19” standard cabinet. Strictly following the IEC and GB standards, it is suitable for the junction of Zone 1-2 and Zone 2-3 of the lightning protection zone, effectively defending against damage to sensitive network equipment caused by lightning induction, grid fluctuations, electrostatic discharges and load impact.
Functional Features:
✅ Dual protection mechanism
- Two-stage series composite protection: Low residual pressure and long life provide consistent protection.
- Triple protection for over-current, over-voltage and clamping: Extremely fast response (≤1ns), instantaneous suppression of surge impacts.
✅ High-speed network compatibility
- Support 1000Mbps Gigabit transmission, insertion loss ≤ 0.2dB, does not affect network speed and stability.
✅ High reliability design
- Nominal discharge current 5KA, maximum through-current capacity 10KA (8/20μs), high protection capability.
- Sheet metal shielded enclosure, good anti-interference, support for 19 ”standard cabinet installation, horizontal/firm mounting can be installed flexibly.
✅ Plug-and-play, no impact on operation
- During thunderstorms, equipment does not need to be powered down and communications continue to run for seamless protection.
Typical Applications:
- Enterprise local area network (LAN), data center, server room network equipment
- Interface protection for network switches, routers, servers, firewalls, etc.
- Network communication links for monitoring systems, intelligent buildings, industrial Ethernet, etc.
- Outdoor network equipment for communication base stations, radio and television transmission systems, etc.

Installation and Wiring Guide
1. Installation location recommendations
- Deployed in series on protected equipmentRecent front-endThe signal path: Signal source (surge) → SPD input (IN) → SPD output (OUT) → protected equipment.
- Be sure to connect the wires according to the “IN” and “OUT” signs, and do not reverse the connection.
2. Grounding requirements
- Grounding wire cross section ≥ 2.5mm², grounding resistance ≤ 4Ω.
- The PE terminal must be equipotentially connected to the lightning protection ground or the equipment enclosure.
3. Maintenance tips
- No special maintenance is required, and it can be viewed in conjunction with routine system checks.
- If you find the network abnormal, try to remove the SPD temporarily, if it returns to normal then the SPD may be deteriorated and need to be replaced.
