Introduction

  • The IM-FP222GE solves a problem that neither a single-SFP PoE switch nor a dual-SFP non-PoE switch can solve on its own: maintaining fiber ring continuity through a node while simultaneously delivering PoE power to the devices at that node. 
  • With 2 × Gigabit SFP fiber ports and 2 × IEEE 802.3af/at PoE RJ45 ports, it functions as a self-contained ring node — fiber arrives from one direction, exits in the other to continue the ring, and the two copper ports power local endpoints without breaking the fiber path or requiring a separate PoE injector at the cabinet.
  • This combination matters in practice because ring topologies and PoE requirements coexist at almost every node in real distributed infrastructure. 
  • A surveillance ring node needs to pass traffic to the next camera cluster and power its own two cameras. 
  • A subway PIS node needs to maintain the fiber ring to the next station and power the local display panels. 
  • An outdoor monitoring cabinet needs dual-fiber redundancy and local device power from a single compact unit on a single DIN-rail slot. 
  • The IM-FP222GE delivers all of this in a 114 × 93 × 35mm chassis drawing ≤5W for its own operation, with a 60W PoE budget available entirely for the two connected endpoints — backed by 6KV surge protection, ±15KV ESD air discharge immunity, and a -40°C to +75°C operating range that matches the environments where this combination of capabilities is most needed.

Key Features

  • 2 × 100/1000M SFP + 2 × 10/100/1000M PoE RJ45 — Ring Node + PoE in One Device — The defining capability: dual SFP ports sustain fiber ring or chain topology continuity while both copper ports simultaneously deliver PoE power to local endpoints — a function that requires two separate devices (a dual-SFP media converter plus a PoE injector) when split across conventional hardware
  • IEEE 802.3af/at on Both RJ45 Ports (30W/port, 60W total budget) — Full PoE+ on every copper port; automatic PD classification delivers 15.4W or 30W as required; non-PoE devices connect safely without risk; dedicated per-port orange PoE LED confirms active power delivery at a glance
  • Dual SFP Fiber Flexibility — SM (20–120km) and MM (500m–2km) supported; BiDi single-fiber modules compatible for single-strand ring segments; mix SM and MM modules in the two SFP slots to bridge different fiber types at a transition node
  • ≤5W Self-Consumption, 60W Fully Available for PoE — The switch draws negligible power for its own operation; the full DC 48V input budget is directed to PoE delivery rather than internal circuitry — meaningful in solar-powered and battery-backed field installations where every watt of power budget counts
  • 6KV Ethernet Surge Protection — Both RJ45 ports hardened against high-voltage transients from outdoor cable runs, lightning-induced surges, and electrical interference from adjacent industrial equipment
  • ±15KV ESD Air Discharge / ±6KV EFT / Surge Differential ±2KV / Common ±6KV — Full IEC 61000-4 five-parameter industrial EMC immunity; CE-EMC / CE-LVD EN IEC 62368-1 / FCC Class B certified
  • DC 48V Input (max 52V) with Reverse-Connection Protection — Direct integration into 48V DC infrastructure; hardware polarity protection tolerates field wiring errors without damage to the unit
  • 8Gbps Non-Blocking Switching / 5.952Mpps / <10µs Forwarding Delay — Wire-speed forwarding across all 4 ports; store-and-forward with full frame integrity verification
  • 6-PIN Industrial Power Terminal Block — Permanent screw-terminal DC wiring; no barrel connector; standard industrial panel wiring practice
  • Auto MDI/MDIX / IEEE 802.3x Flow Control — Plug-and-play copper wiring; flow control prevents frame loss under burst conditions
  • -40°C to +75°C / IP40 / DIN-Rail or Wall-Mount / 114 × 93 × 35mm / 0.35kg
  • CE / FCC Class B / LVD EN IEC 62368-1 / 3-Year Warranty + Lifetime Technical Support

Applications

  • Fiber Ring Surveillance Nodes — Pass-Through + Local Power — The most precise fit: a perimeter or campus surveillance fiber ring visits each camera cluster location in sequence. At each stop, the ring must continue to the next node while the local cameras need both connectivity and power. The IM-FP222GE is the single device that does both — one SFP receives from the upstream node, the other SFP forwards to the downstream node, and both copper ports power the two cameras at this location. No injector, no additional media converter, no second DIN-rail slot consumed. Multiply this across 20 or 50 ring nodes and the installation simplification is substantial
  • Subway & Rail PIS Ring Nodes — Passenger information systems in metro and railway stations deploy displays, IP speakers, and cameras at each station connected by a fiber ring that must remain intact even when individual station equipment is serviced. The IM-FP222GE sits at each station node: ring continuity is maintained through both SFP ports regardless of copper port activity, and the two local PIS display terminals or cameras receive PoE from the same compact unit — no rack space, no additional power supply at the station cabinet
  • Wind Turbine Nacelle & Tower Networks — Individual wind turbines in a farm are connected by fiber in a ring or daisy-chain topology for SCADA communication. At each turbine, the network node must forward traffic to the next turbine while powering nacelle-mounted IP cameras and vibration sensors. The IM-FP222GE's compact form factor fits within the turbine tower base cabinet, its wide-temperature operation handles the extreme cold of winter deployment, and its dual-SFP architecture keeps the inter-turbine fiber path live while delivering PoE locally — a combination that a single-SFP PoE switch at the end of a spur cannot provide
  • Smart Grid Distribution Automation Nodes — Medium-voltage distribution networks deploy intelligent switching devices, fault indicators, and IP cameras at pad-mounted transformers and sectionalizing cabinets along the feeder. Each node connects to the fiber protection ring and powers local monitoring hardware. The IM-FP222GE's IEC 61000-4 Level 3 immunity handles the electrical environment of distribution equipment; its dual-SFP ring participation ensures feeder automation communication is never interrupted by a local device failure; its PoE output powers the local camera or sensor without a separate injector in an already-crowded outdoor cabinet
  • Tunnel & Underground Infrastructure Monitoring — Road tunnels, rail tunnels, and underground utility corridors connect IP cameras, CO/NO2 sensors, emergency call points, and ventilation controllers along fiber rings where each node must maintain ring integrity and power two or three local devices. Space inside tunnel equipment niches is extremely limited; combining ring pass-through and PoE delivery in the IM-FP222GE's 114mm × 93mm footprint makes it the practical choice where mounting a second device alongside is physically impossible
  • Offshore & Marine Remote Monitoring — Oil platforms, offshore wind substations, and marine vessel networks run fiber for electromagnetic immunity and distance, with local sensors and cameras powered by 48V DC plant. Each fiber node along the platform or vessel must keep the ring alive for redundancy while powering local safety cameras and environmental monitors. The IM-FP222GE's sealed IP40 construction, -40°C cold tolerance, and full IEC 61000-4 immunity suit the salt-air, vibration, and temperature extremes of marine and offshore environments where component replacement is costly and reliability is non-negotiable
  • Military Forward Operating Base Networks — Tactical fiber networks at forward bases connect perimeter cameras, access control points, and communications equipment along fiber rings where each node must be self-sufficient: ring continuity maintained, local devices powered, zero configuration required, and no management interface exposed to potential compromise. The IM-FP222GE's unmanaged architecture eliminates the CLI and Web GUI attack surface entirely; its hardened industrial construction meets the physical durability requirements of field-deployed military infrastructure; and its compact DIN-rail form factor integrates into the standard portable equipment racks used in expeditionary deployments
