C33 2011-03-21 Page 1 of 1 C33 : Properties of cabled BendBright-Elite Singlemode fibre Ultra bend insensitive, low water peak fibre; G.657 B3 & B2 and G.657 A2 General and application This ultra bend insensitive, low water peak fibre, gives unsurpassed bending performance at all wavelengths. With bend losses less than 0.1 dB for 1 turn at 5 mm at 1550 nm, Draka’s BendBright-Elite offers unmatched value to customers that need to reduce the size of their components or to those who wants to introduce the fiber in customer’s home. Its tight geometry is guaranteed over the entire length of the fiber, a pre-requisite for automated inter-connectorization practices. This fiber is 100% screen tested at 2% to guarantee its "zero loss" performance at risky bends. Draka’s BendBright-Elite is still based on conventional technology. It is an all solid silica fibers, without voids or other hole structures. It can be easily fusion spliced by any commercial splicer and requires no specific connectorization procedure. The fibre fulfils the new ITU G.657 B3 and G.657 B2 and G.657 A2 specification (edition 2009), as well as G.652.D.
