52-Port Managed Switch
High-density fiber aggregation, failover in sub-seconds, and wire-speed Layer 3 routing are required for modern enterprise backbone networks, metro surveillance hubs, and industrial automation facilities. Standard copper-based or Layer 2 access switches can find it difficult when applying complex multi-VLAN distribution, long-distance optical links, and dynamic routing protocols such as RIP and OSPF on campus networks. The LANMUS LM-4804XS-SFP+L3 overcomes these enterprise networking challenges by combining 48 Gigabit SFP optical slots, 4 ultra-fast 10G SFP+ fiber uplinks, Layer 3 dynamic routing, sub-20ms ERPS ring self-healing support, and AC+DC dual power redundancy into a tight, 1U rackmount chassis.

What is the LANMUS LM-4804XS-SFP+L3?
The LANMUS LM-4804XS-SFP+L3 is a 52-port, Layer 3 managed industrial Ethernet fiber switch designed for high-density optical access and core aggregation. It features 48 dedicated Gigabit SFP fiber modules and 4 ultra-fast 10G SFP+ optical uplink modules that enable service providers and system integrators to combine multiple optical links from remote edge switches, IP cameras, or industrial nodes into a single 10-Gigabit core.
The switch offers non-blocking full wire-speed traffic handling with a powerful switching architecture of 176 Gbps and a forwarding rate of 131 Mpps. The LM-4804XS-SFP+L3 supports full L3 routing functions, such as dynamic RIPv1/v2 protocol support and OSPFv2 protocol support in addition to IPv4/IPv6 static routing. The switch is designed to withstand the rigors of some of the toughest environments, such as intelligent transportation, rail transport, green energy, mining, and smart cities, with AC+DC dual redundant power inputs and an IP40-rated aluminum alloy chassis.
Key Features
1. Ultra-High Density Fiber Aggregation with 10G Uplinks
The LM-4804XS-SFP+L3 is a large concentration point that provides 48 Gigabit SFP slots and 4 dedicated 1/10G SFP+ uplink ports. Network architects can now link field nodes that are separated by as much as 120km with a single-mode (up to 120km) or multi-mode fiber transceiver with no need for an extra copper-to-fiber media converter.
2. Full Layer 3 Routing Engine (RIPv1/v2 & OSPFv2)
The switch offers high-speed hardware-based Layer 3 packet forwarding. By supporting dynamic RIP and OSPFv2 routing protocols as well as 128 IPv4/IPv6 static route entries, inter-VLAN routing and subnet traffic management occur locally on the switch. This minimizes unnecessary backhaul traffic to core routers and optimizes network latency.
3. Industrial ERPS Sub-20ms Ring Self-Healing
The LM-4804XS-SFP+L3 supports ITU-T G.8032 ERPS (Ethernet Ring Protection Switching) for lines that are critical for communication. All ports can be in chain, ring or star topologies. It takes less than 20 milliseconds for the network to reconnect if a fiber cable is cut. STP/RSTP/MSTP spanning tree protocols are also supported.
4. AC+DC Dual Redundant Power Inputs
It has a redundant power system to ensure uninterrupted operation in industrial & utility applications, with both AC (100-240V) and DC (36V~72V) power feeds. The secondary source power will take over the load of the primary power source if the primary power source fails or if an outage occurs.
5. Multi-Layer Security & Traffic Shielding
The LM-4804XS-SFP+L3 delivers powerful protection against unauthorized access to the network and attacks. Security features include 802.1X port authentication, 802.1X MAC authentication, 256 time-based ACL policies, Denial of Service (DoS) attack protection, TACACS/TACACS+ and DHCP Snooping with Option 82 binding.
6. Industrial-Grade Reliability & Fanless Design
Built inside an aluminum alloy shell for optimal thermal dissipation, the fanless design reduces mechanical wear and noise while preventing dust accumulation. Reinforced with 6KV lightning protection, ±15kV air ESD immunity, and anti-vibration/shock compliance (IEC60000-2 series), the switch operates dependably between -20°C and +55°C.
Performance & Real-World Behavior
Project: The Regional Expressway Traffic Monitoring & Toll Trunk Network (RETTN) in East Africa project was for the Regional Expressway Traffic Monitoring & Toll Trunk Network (RETTN) in East Africa.
Challenge: A highway authority needed an optical backbone that spanned 80 kilometers of highway to link roadside emergency phone stations, toll stations, and variable message signs. The requirements were for a high port-density optical aggregation switch with dynamic routing, high-level ESD/surge protection, and sub-20ms ring redundancy over long-haul fibre links.
Solution: Our engineering team deployed the LANMUS LM-4804XS-SFP+L3 at main highway control centers.
- Optical Aggregation: Using 48 SFP optical ports fitted with 40km single-mode transceivers, the switch concentrated all roadside fiber nodes into a single central hub.
- Dynamic Routing & Redundancy: OSPF routing managed traffic paths across toll plazas, while G.8032 ERPS provided ring recovery in under 20ms during unexpected line breaks.
- Industrial Hardening: The IP40 aluminum alloy shell, 6KV lightning protection, and AC+DC dual power supplies ensured reliable operation during severe equatorial thunderstorms and grid fluctuations.
Typical Deployment Scenarios
Substation & Power Utility Optical Backbone
The communications network in a power transmission system must be able to be immune to high electromagnetic interference (EMI), and long distances must be optical. The LM-4804XS-SFP+L3 is an aggregation core that receives fiber feeds from up to 48 local field switches via single-mode SFP modules from high-voltage yards. It is equipped with dynamic path routes, using OSPF routing, and has dual power inputs with AC+DC, providing power station switchover integrity.
Citywide Fiber IP Surveillance Trunk
Municipal surveillance systems aggregate thousands of high-definition camera feeds over optical lines. With 48 SFP slots and 4 10G SFP+ uplinks, the LM-4804XS-SFP+L3 consolidates optical feeds from multiple regional ring switches. IGMP v1/v2/v3 Snooping and Multicast VLAN features ensure smooth video streams without broadcast flooding, while 10G SFP+ ports forward combined video streams directly to central NVR storage arrays.
When Should You Use the LANMUS LM-4804XS-SFP+L3?
The LANMUS LM-4804XS-SFP+L3 is a model for high-performance enterprise and industrial network solutions. This model is suitable for use in a design where the following features are required:
- High-density optical fiber aggregation (up to 48 SFP fiber channels in 1U).
- High-speed 10G SFP+ optical trunk links to main core networks or data centers.
- Layer 3 dynamic routing (OSPF, RIP) directly at the aggregation layer.
- Long-distance optical loop ring failover recovery under 20ms.
