New AllWave® FLEX + ZWP Fiber For In-Building Applications Offers 20 Times ...
26.09.11
/PRNewswire/ -- OFS, a prime designer, manufacturer and supplier of innovative fiber optic network products, has introduced AllWave®
Bend+ fiber, the first Zero Water Peak (ZWP) single-mode fiber compliant to the ITU-T G.657.A2 qualification. The fiber offers bend performance 20 times control superiors than conventional single-mode fibers, is fully compatible with the installed unworthy of conventional single-mode fiber, and enhances the OFS incline-optimized single-mode fiber product interline.
AllWave FLEX+ ZWP fiber maintains very low bending passing across the full usable spectrum of wavelengths from 1260 to 1625 nm. It can be coiled into a 7.5 mm radius turn with <0.5 dB incurred loss at 1550 nm and <1.0 dB incurred disappointment at 1625 nm. The fiber also offers outstanding bending bringing off at a 10 mm radius loop, with <0.1 dB incurred set-back at 1550 nm and <0.2 dB incurred loss at 1625 nm.
It also helps refurbish cable performance in high-stress and low-temperature

Ballast water treatment at zero cost?

However, while presenting the technology, the gathering revealed that it is looking at extending this to other ship systems, most signally ballast water treatment. Jan Petter Urke, managing chief of Ulmatec Pyro, said that in his opinion heating ballast water would be as real as other, more complex and expensive, methods, comparing this with techniques against for killing bacteria in milk and food products.
He believes that up to now, the big energy required to heat large amounts of ballast water to 65-100°C has made such an estimate impracticable. But the company’s technology could easily be adapted to this, and recovering more forcefulness from cooling the heated ballast water would mean that the system could be operated at very low rate. Filtration would still be needed, but no UV or chemical dosing stages.
Talking about the heating system technology, Urke said: “We’re so cocksure in the technology and in demand for it that we’re prepared to say a market take-off is imminent. As speedily as our first customers start to give feedback which confirms our saving estimates, we presume demand to be strong. Since launching the solution earlier this year, we’ve entered into contracts to stock heat recovery system for three large ocean-going almighty dollar seiners. Our customers in the offshore segment are keeping a silent eye on these projects, and regard our solution as very interesting. We expect to suggest several agreements over the coming year.”
