LX-SW0402C is a 100Mbps single-mode single-fiber optical transceiver with four 100Mbps electrical ports and two 100Mbps SC optical ports. This 10/100M adaptive Ethernet transceiver converts 10Base-T/100Base-TX twisted-pair electrical signals to/from 100Base-SX/LX optical signals. Featuring dual optical ports (A and B), it simplifies pairing with remote devices and enables cascade topologies, offering greater flexibility than conventional single-port transceivers.
Core Functions & Technical Highlights
Hybrid Dual-Optical & Quad-Electrical Architecture
- Optical Ports: 2 × SFP slots compatible with single-mode (10/20/40km) and multimode (550m) fiber, supporting 100BASE-FX/1000BASE-X for backbone and short-range communication.
- Electrical Ports: 4 × 10/100/1000M adaptive RJ45/M12-D ports with PoE/PoE++ (30W/60W per port) to power IP cameras, APs, etc.
Industrial-Grade Design
✅ Wide Temperature: -40°C to 75°C operation (IEC 60068-2-1/-2-2).
✅ High Protection: IP40 metal casing + 6kV surge immunity (IEC 61000-4-5).
✅ Redundancy: Integrated ERPSv2 (<20ms failover) and STP/RSTP for zero downtime.
Scenario-Based Solutions
Smart Grids
- Dual optical ports enable 10km fiber rings for ms-level synchronization (IEEE 1588v2) of substation devices (IEDs/PMUs), meeting IEC 61850-3.
- Electrical ports connect smart meters, transmitting real-time data via Modbus TCP/DNP3 with <0.0001% packet loss (UL 1741).
Rail Transit
- Passes EN 50155 Class S2 vibration tests (5Grms), supports MVB/TRDP for train control, ensuring <5ms latency for 4K PIS video.
- PoE++ powers onboard WiFi, reducing cabling by 60%.
Smart Factories
- Compatible with PROFINET RT/IRT & OPC UA Pub/Sub, connecting robots/PLCs with ≤35% bandwidth usage (IEC 61158-6-10).
- Supports VLAN/QoS for prioritizing critical data (e.g., alarms).
