(3)

Who is NBG Systems and FCT?

• NBG Systems:

• Is the face to the costumer

• The overall service center & customer support • FCT:

• An Austrian independent manufacturer of high quality stainless steel tubes with integrated optical fibers

• A specific component manufacturer of OPGW,

Submarine Cable, and Temperature sensing cable for the various manufacturing companies globally

• A supporter rather then a competitor to all these manufacturing companies

(4)

What is the mission of NBG Systems?

• The mission of NBG Systems is to become a world wide leader, being an independent, neutral and reliable

manufacturer and supplier, of high quality Stainless Steel tubes with integrated Optical Fibers.

• To support the related world wide manufacturing companies of OPGW, Submarine and Temperature sensing cables markets.

Applications of S. S. Tubes

• OPGW

• Submarine cables

• Temperature sensing cables • Sewer cables

• Asphalt cables

• Security fence cables

• New applications like extension and vibration measurement

(7)

Advantages of S. S. Tubes

• Very durable & robust

• Minimum diameters from 1,10mm to 4,20mm • No hydrogen permeability

• High short time max. temperature (up to 300°C) • High long time max. temperature (up to 85°C with

jelly and up to 250°C without jelly)

• High pressure resistance (up to 200bar for

0,20mm wall thickness and 2,70mm diameter) • High solvent resistance

Standard Stainless Steel Tube

• Diameter range

1,10 up to 4,20mm

Standard diameter every 0,10mm (1,10mm

1,20mm, 1,30mm……)

Steps between 0,10mm on request

Wall thickness

1,10 – 1,35mm 0,125mm 1,40 – 1,75mm 0,150mm 1,60 – 2,05mm 0,150 or 0,200mm 2,10 – 2,75mm 0,200mm 2,75 – 3,50mm 0,200mm 3,30 – 4,30mm 0,200 or 0,250mm

(10)

• Material (steel grades)

Standard: DIN 1.4301 ANSI 304

DIN 1.4303 ANSI 305

DIN 1.4306 ANSI 304L

On request DIN 1.4404 ANSI 316L

(11)

• Filling compound

Special tixotropical filling compound With or without hydrogen scavenger

Temperture range normally -30°C up to 75°C Wider range possible

Tubes without filling compound possible

Filling degree typical 78%, for submarine cables up to 90% for better water longitudinally tightness

(12)

• Typical Optical Fiber types (and others)

G651 50/125 and 62,5/125 from J-fiber, Corning and Draka

G652D from Fujikura, Draka, LG, J-fiber, Cabelte and Corning

G655A to D from Fujikura Type LA POF

Insulated copper wire Nothing inside

Plastic tube inside for blown fibre systems

(13)

• Optical Fiber capacity

Depends on application, fiber type, diameter and fiber excess length.

Normally up to 48 fibers

Typical values (produceable, no special application)

1,10 – 1,35 mm 2 fibers 1,40 – 1,75 mm 4 fibers 1,60 – 2,05 mm 8 fibers 2,10 – 2,75 mm 24 fibres 2,75 – 3,50 mm 38 fibers 3,30 – 4,30 mm 48 fibers

(14)

• Optical Fiber Identification

Up to 12 fibers with different colours

With more than 12 fibers, fiber bundling or ringmaking of the fibers is available.

Ringmarking and bundling together is also available With bundling 12 different colours are as well

(15)

• Drum ( Reel ) length

Up to 25km in one piece are available

Max length is limited trough maximal dimensions of drum (diameter 1050mm and width 780mm) and size of steel strip pay off

Max length depends also on tube diameter, requested drum type and wall thickness

(16)

(17)

Multilayer Stainless Steel Tube

• If more than 0,25mm wall thickness are required, then a multilayer tube can be used

• 2, 3 or 4 layers are available

• Diameter up to 4,30mm outside diameter • Many combinations are available

(18)

Multilayer Stainless Steel Tube

• Advantages of multilayer tubes

Higher inside or outside pressure possible Higher side pressure possible

Better kinking performance Higher tensile strength

(19)

Aluminium Coated Stainless Steel Tube

(20)

• FCT is the first producer using this technology • In many cases an aluminum outer surface is

required or requested by customer

• Specifically for OPGW cables near the sea • For OPGW cables without grease

• Better performance than foil covered tubes

(21)

• Facts and Advantages

Outside diameter 2,50 mm up to 4,20mm

Wall thickness always 0,25mm Moisture tested (eddy current)

(22)

(23)

• Facts & Advantages

– Conform method for thick aluminium wall – Min. aluminium 1mm

– Max. aluminium around 4mm – For any specific OPGW design

(24)
