Description
Foxboro PO973JP
Technical Specifications
- Port Configuration: 8 x RJ-45 100Base-TX ports + 8 x SC/ST 100Base-FX fiber ports.
- Uplinks: Typically equipped with Gigabit SFP or RJ-45 uplink ports for backbone connections.
- Management Features: Supports SNMP, RMON, VLAN, QoS, and port mirroring.
Functional Features
- Hybrid Media Access: Resolves both copper and fiber access needs in a single device, saving rack space.
- Industrial-Grade Design: Supports wide-temperature operation with strong resistance to electromagnetic interference.
- Redundant Power Support: Compatible with external redundant power modules (P0973BP) for high power availability.
Application Scenarios
Suitable for factory workshops, substations, and traffic control systems that require simultaneous connection of local operation panels (copper) and remote monitoring centers (fiber).
Performance Parameters
- Transmission Distance: Fiber ports support multi-mode fiber transmission up to 2 km, and single-mode fiber up to tens of kilometers.
- MAC Address Table: Supports large-capacity MAC address learning, adapting to large-scale networks.
Material Composition
Rugged metal enclosure. Fiber ports use high-precision ceramic ferrules, and copper ports feature gold-plated contacts to ensure long-term plug reliability.
Structural Characteristics
The front panel has clearly demarcated sections, with copper and fiber ports arranged separately. Each port is equipped with independent Link/Activity status LEDs.
Working Principle
Performs store-and-forward operations on data frames from both copper and fiber ports at the data link layer. Supports cross-media VLAN segmentation, allowing fiber and copper ports to belong to the same logical network.
Installation Requirements
Pay attention to the bending radius of fiber patch cords to avoid excessive bending that causes optical attenuation. Shielded twisted pair cables are recommended for copper connections and must be properly grounded.
Usage Precautions
- Use dedicated cleaning tools when cleaning fiber ports to prevent dust from affecting optical power.
- Ensure the fiber transmit/receive (TX/RX) directions are correctly matched.
- Regularly monitor the operating temperature and optical output power of the SFP modules.
