Flexible solution for broadband OSP applications

❍ ❍ Tratos Microcable

for installations where duct space is at a premium and has the added benefit of being easy to handle and install. It also provides a simple, neat and commercially viable solution to upgrade a network at a later date as fibre is simply deployed as and when needed. Tratos Microcable can be used in operating temperatures of -30°C/+60ºC. It has been designed and manufactured to IEC 60794.

192 fibres is claimed to be the smallest such cable in the world today. Even with the maximum number of fibres incorporated, Tratos Microcable remains flexible (it has a minimum bending radius of 15 x outer diameter without tension) and is lightweight enough for air-blown installation in very small ducts or sub ducts using Tratos Microduct. Tratos Microcable requires fewer joints in installation, providing reduced resistance when being passed through the ducting.

Electric and fibre optic cable manufacturer Tratos has launched the innovative and cost-effective Tratos Microcable solution for Open Settlement Protocol (OSP) applications in the broadband market. Tratos Microcable contains a high-fibre density but is exceptionally compact and lightweight, thus maximising the fibre count available in a small cable diameter. It is produced in stranded loose tube design and is available in fibre counts from 144 to 192, with outer diameters ranging between 4 and 7.5mm – the 7.5mm Tratos Microcable incorporating

Focus on small buttwelders

Progress continues, as it is planned to enlarge the welding ranges for stranded copper up to 1,600 or even 2,000mm². There has been continuous demand this year for types SE 1, SE 2 and SE 4 buttwelders. These three units cover a total range for stranded copper from 0.08mm² to 35mm² or stranded aluminium from 1.5mm² to 50mm², welds being made using ceramic tubes. A typical application would be in the automotive industry or for electric installations.

August Strecker’s focus this year is on small size electric strand buttwelders. With more than 75 years’ experience, Strecker has gained an enviable reputation in manufacturing electric and cold pressure buttwelding machines and large welding machines for medium or high voltage submarine cables. Here the tendency is straight to welds without tubes, using dual upset welders with automatic flash removal system. A recent development is of machines powered by three-phase transformers, reducing the current consumption and facilitating machine installation in the individual cable factories.
