Optical Fiber OPGW Manufacturing Facility
The special production line of OPGW is equipped with high precision tension control multifiber payoff station, its equipment and its extensive contract manufacturing service in good reputation.
They will concentrate optical fibers and metal tapes by continuous non-stop operation of submarine fiber-optic cables at the line completed in precision molding and welding of FIST (metal tube containing optical fiber).
Product Features
Optical fibre pay-offs and handling:
Optical fibre pay-off stations, with minimum traction, tension controlled and smooth fibre deviation units. THE own or customer bespoke units. Fibre jelly feeding unit with controlled dosing and feeding available.
Metal Roll forming:
In-house manufactured precision roll-forming tools engineered with finite element simulations to impart minimal stress and strain, avoid surface damage and provide process stability. High quality and use of materials assure longevity of the tools. Quick-change carrier systems benefit in low set-up times and operational excellence.
Welding:
High quality laser welding with proprietary orbital seam tracking system. Laser power source and beam quality adapted and configured to best suite the application.
THE automated in-line laser re-weld unit available to assure product integrity for extreme length cables (e.g. submarine cable) during stop/re-start operations.
Quality Control:
In-line monitor and measurement of all geometric parameters with fully integrated in-line continues non-destructive weld seam and tube quality control systems with exclusive ICO (Internal Crack Observer) and ECC eddy current measure.
Draw-down and OL/EFL units:
Down-stream processes are finely controlled to ensure optical fibres are not damaged during forming wand welding and subsequent excess fibre length OL/EFL, where needed, is finely controlled and measured with the drawn-stations and SSL (overlength) units. Finished products can be additional tested with bespoke off-line OL/EFL testing unit.
Tube drum coilers:
Finished tube is wound on to drums on self-traversing THE’s BAT drum coiler, assuring smooth and even tube coiling. Tube tensions and even layering are finely controlled.
Line Controls:
Centralized line control systems, with recipe management to assure process stability and operational excellent. Line controls have data logging capabilities for track and trace requirements of key required process parameters and quality checks as well as prepared for customer industry 4.0 requirements. User friendly HMI and line management systems.
