Flexibility and at the same time robustness in relation to extremely high mechanical stress are needed. These are realised with the OT2000 by cotton filling threads in the interstices, which provide for a stable pair twisting, needed for repeated winding and unwinding, a very close spiral screen and a very thick outer jacket from soft PVC rounds off the cables characteristics.designcond. construction: stranded tinned copper, 7 x 0.20 mm (AWG 24/7)cond. cross section: 0.22 mm²insulation: Foam-Skin PEcore arrangement: 2 cores twisted to a pairshielding: tinned copper spiral shield, 95% coverageouter jacket: PVC, mattoverall diameter: 6.5 mmmechanicsmin. bending radius: 35 mmworking temperature: -20°C / +70°Celectricconductor resistance: 80 O/kmshield resistance: 30 O/kmcapacitance: cond./cond.: 52 pF/mcharacteristic impedance: 110 Onom. attenuation [dB/100m]: 1 MHz: 2.1, 3 MHz: 5.2, 10 MHz: 12.5insulation resistance: > 10 GO x kmtest voltage: cond./cond.: 1200 V, cond./shield: 500 Vouter jacket: PVCouter Ø: 6.5 mmcable color: blackweight: 5.4 kg/m
This cable is designed for transmitting both digital and analogue video signals and is used for both rack applications and installations. The polished solid copper core has a diameter of 0.60 mm and is enclosed in a physically foamed PE dielectric medium that ensures signal transmission with no return loss and ultra-low attenuation. Typical transmission distances under SMPTE standards are 255 metres for SDI video signals, 65 metres for 1.5 Gb/s HD-SDI signals and 47 metres for 3 Gb/s signals. However, in practice longer distances may well be possible depending on the devices used. Effective protection against electromagnetic interference is offered by double shielding comprising an AL double composite layer and an ultradensely woven copper shield providing over 92 per cent screening. The outer jacket is of FRNC material, which is flame-retardant and completely halogen-free – a vital advantage for installations.digital + analog videodouble shielding (100% foil + 90% braid)not suitable for mobile HD-SDI useflame retardant and non corrosive (FRNC)CPR class Eca acc. to EN50575designinner conductor: solid bare copper, Ø 0.60 mminsulation: Foam-Skin PE, gas injected , Ø 2.85 mmshielding: AL/PET/AL double-layer foil + tinned copper braid (92% coverage)outer jacket: FRNCoverall diameter: 4.5 mmmechanicsworking temperature: -30°C / +70°Cmin. bending radius: 25 mmelectriccharacteristic impedance: 75 O ± 1%capacity: 58 pF/mvelocity of propagation: 81 %screening attenuation: > 90 dBnom. attenuation [dB/100m]: 1 MHz: 1.25 MHz: 2.710 MHz: 3.8100 MHz: 10.8135 MHz: 12.4200 MHz: 15.0270 MHz: 17.5500 MHz: 24.2750 MHz: 31.01000 MHz: 36.01500 MHz: 44.93000 MHz: 65.56000 MHz: 95.912000 MHz: 143.8return loss: 30 - 300 MHz: > 25 dB300 - 1500 MHz: > 23 dB1500 - 3000 MHz: > 21 dB3000 - 12000 MHz: > 15 dB
Pro users are always asking us whether we can supply a video cable that’s optimized for short to medium distances. It should have a low external diameter as well as being highly flexible, suitable for drum storage, and rugged enough to cope with frequent patching. All these enquiries inspired us to design the VD083LP – the ideal cable for mobile transmission of digital video signals over distances up to 70 m. The outer PUR jacket is extra-rugged and abrasion- and notch-resistant, providing outstanding protection for what goes on inside. The ultra-finely stranded conductor is enclosed in physically foamed dielectric medium covered with a dual-layer braided copper shield that provides over 98% protection from interference. In line with SMPTE standards, the VD083LP transmits a 1.5-GB signal over distances of up to 70 m, and a 3-GB signal up to 50 m – or even more in practice, depending on the transmitter and signal frequency! And incidentally, the VD083LP is the “little brother” of our famous and universally appreciated VD125LPS for long distances.flexible stranded inner conductorvery dense double tinned copper braidsuitable for mobile HD-SDI userobust PUR jacketDesignInner conductor: stranded bare copper, 19 x 0.16 mmInsulation: gas injected foam PE, Ø 3.7 mmShielding: 2x tinned copper braid, >95% coverageOuter jacket: PUROverall diameter: 6.1 mmMechanicsWorking temperature: -40°C / +80°Cmin. bending radius: Installation: 40 mmOperation: 60 mmCable electricsWave impedance: 75 OCapacitance: 54pF/mShortening factor: 81%DC resistance: inner conductor 44 O/km, outer conductor 7.6 O/kmScreening attenuation: > 90 dBNominal attenuation [dB/100m]: 1MHz 0.9 5MHz 2.0 10MHz 2.8 71.5MHz 8.4 88.5MHz 9.4 100MHz 10.0 135MHz 11.7 180MHz 13.3 270MHz 16.5 360MHz 19.3 540MHz 23.7 750MHz 29.6 1000MHz 34.4 1500MHz 43.2 3000MHz 64.1 6000MHz 98.8 12000MHz 168.4Return Loss: 30 - 300MHz > 24dB 300 - 1500MHz > 22dB 1500 - 6000MHz > 15dB
