I. Characteristics

1. High quality optical fiber provides good transmission performance

2. Accurate fiber excess length control ensures excellence mechanical and temperature performance

3. Strict craft and raw material control for cable stably operating over 30 years

4. The sturcture of all section water blocking and longitudinally armored with both side coated aluminum tape provide good performance of moisture-proof and water blocking

5. Special filling gel filled loose tubes provides optical fiber protection

6. Corrosion resistance phosphated steel wire with high Young's module as the central strength member

7. Longitudinally armored with both side coated aluminum tape and stranded steel wires armoring ensure the request of compressive strength, tensile strength, bulletproof property, heavy duty Direct burial, underwater installation

II. Structure

-> Metallic central strength member

-> PBT-made loose tube
-> aluminum-PE inner sheath
-> galvanized steel wires layer & PE outer sheath

III. Configuration

IV. Application: Direct burial/Underwater

V. Main Mechanical and Environmental Test

Max. Installation Tension; Max. Operation Tension; Crush; Impact; Torision; Repeated Bending; Cable Bend; Temperature Cycling; Water Penetration

VI. Identification and Packing

a. Fiber Colors & Buffer Tube Colors (acc. to TIA/EIA-598-A standards)

Blue, Orange, Green, Brown, Grey, White, Red, Black, Yellow, Violet, Rose, Aqua.

-> Note: special color spectrum can be customized according to customer requests, but it must be clearly described in the order.

b. Sheath Marking: the outer sheath is marked in 1 meter intervals as follows:

DRAKA COMTEQ <year of manufacture> <number and type of fiber> <length marking in meter>

c. Packing: Wooden drums with protection.

d. Delivery Lengths: Standard delivery lengths are 2 km, 4 km, 6 km with a tolerance of - 1% / + 3%
