Core Technical Architecture
LX-SW803-2 adopts a Non-Blocking Architecture switching engine, supporting 8×10/100Mbps full-duplex communication with a backplane bandwidth of 1.6Gbps. Key innovations include:
Dual Interface Options:
- XH2.54mm 4-pin military-grade connector (Vibration resistance: 6Grms | Salt spray resistance: ≥720h)
- Onboard 4-pin pin-header version (Sinking board welding thickness: only 5.2mm | Saves 92% vertical space)
Store-and-Forward Technology:
- Packet error rate: <10⁻¹⁰ (RFC 2544) | Broadcast storm suppression rate: >99%
Industrial-Grade Reliability:
- Operating temperature: -40°C~85°C (supports transient peaks of 105°C)
- MTBF: >250,000 hours (85°C full-load accelerated testing)
II. Industry Scenario Solutions
-
Onboard Networks for Rail Transit
Ensures zero interruption of PIS video streams in a 250km/h high-speed train vibration environment (tested at 12Grms).
Case Study: Mexico City Metro Line 12 (deployed 1,200+ modules, failure rate: <0.02%)
-
Relay Protection for Smart Grids
- ✅ Compliant with IEC 61850-3
GOOSE message transmission latency: <3.5μs (tested at a State Grid 550kV substation).
-40°C cold start time: ≤2 seconds (tested in extremely cold environments in Mohe).
-
High-Density Embedded Systems
The onboard pin-header version is integrated into ABB robotic arm controllers (dimensions: 36×48×5.2mm).
Supports 32-node cascading with backplane throughput efficiency of 99.98% (RFC 2889).
