The FRP 05 line, therefore, stands as a dependable solution for central-office and FTTH ribbon supply networks.
Inline proof test confirms ribbon quality. Test heads check tensile/continuity immediately post-formation. Should they detect any weakness or breakage, the system either discards the flawed segment or adjusts automatically. This immediate feedback reduces waste and blocks faulty ribbons from progressing to cable assembly.
Ribbon lines may add marking/color coding. IDs survive later processing. Pairing color coding with inline proof tests improves traceability and simplifies quality control. Syncing glue/formation/testing yields clear benefits for throughput.
| Process Stage | Key Function | Typical Performance Metric |
|---|---|---|
| Fiber alignment | Arrange coated fibers to target pitch and flatness | ±5 µm registration |
