GJFJH53كابل ألياف بصرية داخلي مدرع بالفولاذ

The functions below explain how this construction is made. They are not a fixed machine count or a final equipment specification.

1. 01

   Fiber coloring & preparation

   Start with the approved optical fiber. Apply and cure the specified identification colors, then rewind; if colored fiber is purchased, verify the incoming identification and package instead.

2. 02

   Protected optical-unit preparation

   Prepare the approved fiber protection and reinforcement before cable formation. A tight-buffer step is included only when the selected sub-unit drawing requires it; it is not assumed from the family name.

3. 03

   Reinforced core & inner protection

   Arrange the protected multi-fiber core, apply the specified aramid reinforcement and form the inner protection required by the approved 53 construction.

6. 06

   Inspection & delivery preparation

   Complete the agreed optical and mechanical checks, inspection records, lengths, marking and packing. HONGKAI handles the agreed acceptance inspection and delivery; process videos are not batch test records.

Confirm the actual fiber-protection system, inner layer, steel armor and jacket. The related indoor formation footage does not demonstrate the armor or the complete GJFJH53 construction. Final materials, equipment interfaces and acceptance follow the approved drawing and order.

Only matching process functions have video controls. Other stages retain their explanation where suitable footage has not been established. These clips are not one continuous factory tour or a batch inspection record.

Independent factories manufacture the finished cable; HONGKAI handles customer-facing supply, payment, agreed acceptance inspection and delivery. Some equipment customers also manufacture the cables we supply. The actual source, specification and acceptance requirements are confirmed for each order.
