144 Fiber Optic Cable Junction Box Specifications

A 144-core fiber optic junction box typically features 6 fiber trays, IP65–IP68 protection, mechanical or heat-shrink sealing, and durable plastic construction suitable for outdoor and indoor installations.

General Features

  • Capacity: Supports up to 144 fibers, usually organized in 6 splice trays, each accommodating 24 fibers .
  • Sealing Type: Available in mechanical sealing (compression latches and glands) or heat-shrink sealing, ensuring watertight and dustproof protection .
  • Material: Constructed from reinforced plastic, polypropylene (PP), or polycarbonate (PC), providing high strength, corrosion resistance, and durability in harsh environments .
  • Protection Rating: IP65 to IP68, offering excellent resistance to dust, water, and environmental stress .

Design and Configuration

  • Ports: Typically 2–6 inlets and 3–4 outlets, supporting both in-line and branching fiber connections .
  • Mounting Options: Can be installed aerially, on poles, in pits, ducts, or on walls, with optional mounting brackets for flexibility .
  • Splice Management: Designed for easy re-entry and maintenance, with trays and holders that organize and protect spliced fibers .
  • Environmental Compliance: Many models comply with RoHS, REACH, and EU/UK hazardous substance regulations, ensuring safe use in various regions .

Applications

  • Telecommunications networks, FTTH (Fiber to the Home), CATV, and large-scale fiber optic deployments .
  • Suitable for outdoor harsh environments due to UV, salt spray, and temperature resistance, as well as indoor industrial installations .
  • Can house PLC splitters for passive optical networks, supporting network expansion and high-density fiber management .

Key Advantages

  • Reliable sealing ensures long-term protection against moisture, dust, and chemicals .
  • High mechanical strength prevents damage during installation or environmental stress .
  • Flexible installation and re-entry design allow for maintenance without compromising fiber integrity . These specifications make 144-core fiber optic junction boxes ideal for high-capacity, durable, and versatile fiber network deployments.
