72-core fiber optic splice closure

72-core optical fiber splice closures are designed for aerial, duct, and buried applications, offering secure sealing, multiple cable entry ports, and flexible fiber management.General FeaturesCapacity: Supports up to 72 single-fiber splices or higher if ribbon splicing is used .Applications: Suitable for aerial, duct, pole, wall, manhole, and direct-buried installations .Closure Types: Available in dome-type (vertical), horizontal, and inline configurations .Re-entry: Many closures allow no-cost re-entry for maintenance and fiber rearrangement .Physical SpecificationsDimensions: Example SCF-4C18-01 closure has a 4-inch diameter and 18-inch dome length .Ports: Typically 3–8 cable entry/drop ports, accommodating cable diameters from 10 mm to 22 mm .Material: High-intensity engineering plastics (ABS) for the body, stainless steel for external components, and polypropylene domes for mechanical strength and environmental protection .Sealing: Mechanical end caps, adhesive rubber strips, and sealing tapes provide reliable environmental protection and moisture resistance .Fiber ManagementSplice Trays: Modular tray systems allow organized fiber routing, with options for single-fiber or ribbon splicing .Slack Storage: Full slack storage baskets and tray stackers accommodate excess fiber length .Cable Loops: Multiple loop diameters (e.g., 12.5 mm, 17 mm, 20 mm) allow flexible cable entry and secure fiber placement .Mounting and StandardsMounting Options: Pole-mount, wall-mount, aerial, and underground installations .Standards Compliance: RoHS compliant, Telcordia GR-771 tested, and in some cases, compliant with National YD/T814.1-2004 standards .Additional FeaturesEnvironmental Protection: Resistant to corrosion, mechanical impact, and lightning; suitable for harsh outdoor conditions .Maintenance: Closures can be reopened for fiber maintenance or expansion without compromising sealing .Flexibility: Optional add-a-cable kits allow consolidation of multiple flat cables, enhancing network scalability . These specifications make 72-core splice closures versatile for telecom, CATV, and fiber-to-the-premises networks, providing secure, organized, and maintainable fiber connections.
