Fiber Optic Cable Fixing Plate

Fiber optic cables are fixed using breakout plates, wall plates, and clamps to secure the cable sheath, strength members, and tubes, ensuring proper routing and protection in racks or enclosures.

Cable Fixing in Patch Panels and ODFs

In an Optical Distribution Frame (ODF) or patch panel, fiber optic cables are routed into the frame where they are spliced to pigtails. Horizontal and vertical plates, called breakout plates, are used to fix the cable sheath, central strength member, Kevlar, and tubes before the fibers are directed into splice trays. This prevents mechanical stress and maintains fiber integrity. Microducts and micro cables may require additional racks with special holders for vertical routing near the ODF .

Wall Plate Fixing

For wall-mounted installations, fiber wall plates provide a secure interface for fiber connectors. Plates like the Leviton SDX Metal Fiber Adapter Plate can hold multiple QUICKPORT connectors and are typically mounted on standard electrical boxes or surface-mount enclosures. The plate ensures that fibers are organized, protected, and accessible for patching .

Cable Clamps and Accessories

Preformed suspension hardware, down lead clamps, and anti-vibration hammers are used to secure fiber optic cables on poles or towers. Rubber or metal insulating clamps are selected based on cable type (ADSS or OPGW). These accessories protect the cable from vibration, friction, and mechanical stress, and are designed for reliable, fast installation . Down lead clamps fix cables to poles or towers, while preformed eyelets or repair bands can restore damaged cables to their original mechanical strength.

Material Considerations

Fiber optic fixing hardware is typically made from PVC or high-impact rigid materials, offering chemical resistance, strength, and durability across extreme temperatures. Proper selection of materials ensures long-term stability and protection of the fiber optic network .

Best Practices

• Always secure the sheath and strength members before stripping fibers.
• Use breakout plates for organized routing in racks or enclosures.
• Select appropriate clamps for the cable type and installation environment.
• Protect fibers from vibration, bending, and mechanical stress.
• Ensure accessibility for maintenance and future expansion. By following these methods, fiber optic cables can be safely fixed, organized, and maintained, ensuring optimal performance and longevity of the network.
