Start with how the cable moves
The important distinction is the relationship between the cable and the spring-loaded ferrule carrier. Cable construction determines whether the fiber can move relative to the outer cable structure, or whether the cable and carrier need to move together.
Neither architecture is intrinsically superior. Select the configuration for the cable and the finished connector assembly.
Three configurations, three selection considerations
Pull-proof
For compatible loose-structure cable. The primary tensile load passes through the cable reinforcement to the stationary terminus body, while the ferrule carrier retains its operating travel. The cable must permit the required differential movement.
Non-pull-proof
For tight-structure cable. The cable attaches to the movable ferrule carrier. The finished assembly needs suitable external strain relief because excessive cable tension can retract the carrier and interrupt optical contact.
900 µm non-pull-proof
A dedicated configuration for 900 µm buffered or sub-jacketed fiber. Check the actual cable cross-section: the nominal outer dimension does not establish whether reinforcement is present. Verify the attachment and process against the controlled product drawing.
What to confirm before choosing
- The cable cross-section and the available fiber or buffer movement.
- How cable tension is carried through the finished assembly.
- The required ferrule travel and external strain relief.
- The approved termination instructions and program requirements.
