Specifications and Models of Micro-cable Fiber Optic Splice Boxes

Micro-cable fiber optic splice boxes are compact, versatile enclosures designed for splicing and connecting optical fibers, with models supporting 12 to 24 fibers and various adapter types for industrial, ATEX, and space-constrained applications.

FIMP-M Splice Box

The FIMP-M is a compact splice box measuring 115 x 61 x 113 mm, suitable for both singlemode and multimode fibers (50µ and 62.5µ) and supporting up to 12 fiber splices. It accommodates a wide range of couplings, including SMA, ST, SC, LC-Quattro, FC-PC, SC-RJ, and E2000, providing flexibility for different network requirements. The box is designed for moderate fiber connectivity and is ideal for smaller-scale installations or specific networking scenarios. Its durable construction ensures reliability in standard environments .

FIMP-M-EX Splice Box (ATEX)

The FIMP-M-EX variant is designed for ATEX environments, making it suitable for industrial areas with potentially explosive atmospheres. It features DIN-rail mounting, a stainless steel powder-coated case, and supports up to 12 fibers. Standard configurations include ST, SC, E2000 duplex, or LC-Quattro adapters, with multimode pigtails (62.5/125 µm OM1, 50/125 µm OM2/OM3). Optional mounting kits for walls or 19” racks are available. The box ensures equipotential bonding via the DIN rail clip and a separate grounding screw to prevent spark discharges .

FO MICRO Splice Box

The FO MICRO Splice Box is optimized for very small spaces, maintaining the minimum bending radius and environmental protection. It can accommodate up to 24 fiber splices and supports connections with up to 4 adapters. Installation options include wall, subfloor, distribution compartments, or cable ducts, with snap-on mounting on top hat rails. The box features sealed cable entries on both sides and internal strain relief using cable ties. The cover is designed for easy snap-on installation .

Phoenix Contact FDX 20 Series

The FDX 20 series from Phoenix Contact provides compact DIN-rail splice boxes for high-speed, real-time data transmission. These boxes support up to 12 duplex front connections, offering flexible connection technologies and reliable protection concepts. They are designed for future-proof high-speed fiber optic networks, ensuring secure and continuous data transmission .

Key Considerations

  • Fiber Type Compatibility: Singlemode and multimode fibers are supported across most models.
  • Adapter Options: Common adapters include ST, SC, LC, E2000, and SMA, with some models offering LC-Quattro or SC-RJ.
  • Capacity: Ranges from 12 fibers (FIMP-M, FIMP-M-EX, FDX 20) to 24 fibers (FO MICRO).
  • Mounting Options: Wall, subfloor, DIN-rail, or 19” rack mounting depending on the model.
  • Environmental Suitability: Standard, industrial, and ATEX-compliant variants are available.
  • Space Efficiency: Micro-cable splice boxes are designed for compact installations while maintaining fiber protection and bend radius compliance. These micro-cable fiber optic splice boxes provide flexible, reliable, and space-efficient solutions for a variety of optical network applications, from industrial environments to compact distribution setups.
