Optical Fiber Ribbon Loose Tube Production Line For 24 core×6 layers
1. Application
The line is mainly for extruding optical fiber ribbons (24 core×6 layers). The material is PBT, PP or PE. The outer diameter of loose tube is ensured to be round, even and smooth. The constant speed or lifting speed should ensure the stability of the outer diameter.
2. Main technical data
2.1 Big loose tube data request
2.1.1 Structure speed 80m/min
2.1.2 Production speed 10-60m/min(details as below)
2.1.3 Optical fiber ribbon reels quantity 6
2.1.4 Optical fiber ribbon pay-off tension (1.5-5)N±0.2N
2.1.5 Optical fiber pay-off reel size Φ410×390×Φ50.8mm
2.1.6 Ribbon pay-off speed 0-80m/min
2.1.7 Outer diameter of loose tube 4.0-20.0mm
2.1.8 Take-up tension 10-100N
2.1.9 Auxiliary capstan tension 20-200N
2.1.10 Portal type rail travelling take-up, reel size PN1250-PN1600
2.1.11 Optical fiber E.F.L control range 0-4‰
2.1.12 Outer diameter even ≤0.1mm
2.2 Other requests
2.2.1 Hot water temperature room temperature～85℃±3℃ (two grade hot water controlling)
2.2.2 Cooling water temperature 14-20℃±3℃ (supplied by the buyer’s side)
2.2.3 Meter accuracy of capstan counter <1‰
2.2.4 Loose tube sickness uniformity ≤10%, the thickness uniformity is defined as [(max thickness-mini thickness)/thickness nominal value]*100%
2.2.5 Additional attenuation after loose tube Δα<0.01dB/km
