STANDARDS Telefonica Specification ERQ.f6.0217 ■ Fibre: UIT-T G.657 A2 DESCRIPTION AND APPLICATION 16 to 48 optical fiber cable constituted by a set of small diameter micromodules that facilitate their installation in canalization buildings. These cables use a fiber optimized against curvatures allowing reducing the radius of curvature of the cable for use indoor applications. CONSTRUCTION • Tubes: Micromodules with 4 or 8 optical fibers with thixotropic compound and containing single mode optical fibers. Colour code according to Tables 1 and 2. • Mechanical reinforcement: Aramid yarns as traction resistant. • Outer jacket: Ivory coloured LSZH compound. • Sheath marking : The cable sheath will be marked with white ink at regular intervals with the following information: o Manufacturer's name (CCSA) / Year manufacturer / Number of fibers / Fiber type /Sheath type / TELEFONICA /Footage o Other sheath marks available upon request OPTICAL FIBER CHARACTERISTICS The parameters of the optical fiber are compliant with the ITU-T G.657 A2 recommendation.
