Company and Product Presentation

Company Presentation NBG Systems & FCT are private companies owned by NBG Holding Both are Austrian companies, operating under the highest European Union requirements & specifications NBG Systems is the sales branch of the overall NBG Holding daughter companies, while FCT is responseable for the R & D and production of the different products NBG Systems & FCT have more then 20 years of experience in the field of fiber optics 2

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 3

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. NBG Systems is fully qualified and preferred as a European company to do business globally 4

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 6

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 7

Diameter range Standard Stainless Steel Tube 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 9

Standard Stainless Steel Tube 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 alloy 825 (for oil and gas industry) 10

Filling compound Standard Stainless Steel Tube 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 11

Standard Stainless Steel Tube Typical Optical Fiber types (and others) G651 50/125 and 62,5/125 from J-fiber, Corning G652D from Fujikura, Draka, LG, J-fiber, Cabelte G655A to D from Fujikura Type LA POF Insulated copper wire Nothing inside Plastic tube inside for blown fibre systems Every high quality fiber should be possible to use, also with HT-, metal- and polyamide- coating (silicon coating is not possible!) 12

Standard Stainless Steel Tube 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 13

Standard Stainless Steel Tube 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 available 14

Standard Stainless Steel Tube 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 15

Multilayer Stainless Steel Tube 16

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 17

Multilayer Stainless Steel Tube Advantages of multilayer tubes Higher inside or outside pressure possible Higher side pressure possible Better kinking performance Higher tensile strength 18

Thinwall type Aluminium Coated Stainless Steel Tube 19

Aluminium Coated Stainless Steel Tube 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 Higher short time maximum temperature achieved 20

Aluminium Coated Stainless Steel Tube Facts and Advantages Outside diameter 2,50 mm up to 4,20mm Wall thickness always 0,25mm Moisture tested (eddy current) For greaseless OPGW construction 21

Thick wall type Aluminium Coated Stainless Steel Tube 22

Aluminium Coated Stainless Steel Tube Facts & Advantages Conform method for thick aluminium wall Min. aluminium 1mm Max. aluminium around 4mm For any specific OPGW design 23
