Description
Foxboro A4H124-4FX
Technical Specifications
- Port Type: All-fiber ports (100Base-FX), typically SC or ST interfaces.
- Stacking Capability: Supports stacking of up to 8 units to form a unified logical switching matrix.
- Management Features: Supports VLAN, STP/RSTP, QoS, and port aggregation.
Functional Features
- Strong Anti-Interference: All-fiber transmission is completely immune to Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI).
- Long-Distance Transmission: Supports multi-mode transmission up to 2 km or single-mode up to tens of kilometers.
- High Availability: Supports Rapid Spanning Tree Protocol (RSTP) and redundant power supplies for millisecond-level fault recovery.
Application Scenarios
Applicable to substation automation, rail transit signaling systems, and large-scale factory fiber backbone ring networks where high reliability is critical.
Performance Parameters
- Optical Power Budget: High-sensitivity receivers support long-distance link budgets.
- Switching Latency: Microsecond-level store-and-forward latency.
Material Composition
Reinforced metal enclosure, industrial-grade optical modules, and high-temperature-resistant components.
Structural Characteristics
The front panel features densely arranged fiber ports, each with independent Link/Act LEDs for quick fiber link status troubleshooting by O&M personnel.
Working Principle
Performs signal conversion between optical and electrical domains, regenerating, reshaping, and amplifying optical signals, while executing switching and filtering functions at the data link layer.
Installation Requirements
Use the correct type (multi-mode/single-mode) and interface (SC/ST) for fiber patch cords. Keep dust caps on optical modules when not in use to prevent port contamination.
Usage Precautions
- Never look directly into fiber ports, as laser light can cause eye damage.
- Keep fiber connector end faces clean; clean with lint-free wipes and alcohol.
- Avoid excessive bending or pressure on fiber optic cables.
