Product Description
Product Parameters for P0926AH (Splitter/Combiner)
📘 Product Overview
| Field | Details |
|---|---|
| Manufacturer | Foxboro (by Invensys, now Schneider Electric) |
| Part Number | P0926AH |
| Product Type | Splitter/Combiner (Passive Fiber Optic Distribution Unit) |
| Function | Performs quadruple to dual (and vice versa) signal conversions in fiber optic IEEE 802.4 compatible networks, connecting a fault-tolerant pair of Fiber Optic Carrierband LAN Interfaces to a pair of redundant active concentrators |
| System Compatibility | I/A Series fiber optic LAN networks |
| Associated PSS Document | PSS 21H-7F7 B4 |
⚙️ Functional Specifications
| Feature | Specification |
|---|---|
| Signal Conversion | - Combines four redundant signals from a pair of Fiber Optic Carrierband LAN Interfaces into two signals directed to two redundant active concentrators - Splits two signals from concentrators into four signals for the Interfaces |
| Network Role | Maintains network redundancy while reducing redundant cabling, increasing the maximum number of I/A Series nodes from 4 to 9 per redundant concentrator pair |
| Optical Loss | 5.3 dB per channel |
| Connectors | 12 ST-type fiber optic connectors (connecting to four internal 2x1 couplers) |
| Network Topology | Supports star topology in redundant fiber optic LANs (see Figure 3) |
| Device Compatibility | Must connect to active devices (e.g., active concentrators) that echo signals; cannot directly connect to passive devices (e.g., passive star or Fiber Optic LAN Converter) due to excessive signal loss |
| Cable Requirement | Customer-supplied multimode graded-index glass fiber cables (62.5 micron core, 125 micron cladding) with ST-type connectors |
| Maximum Cable Length | 10 km (6.2 mi) per run, subject to hardware/software constraints (consult Foxboro representative for specific limits) |
