Micro Optical Fiber Cable
ZTT Micro Optical Fiber Cable (spec ZTT 17-78748-1-F) is designed for blowing installation into microducts. The range covers ultra-slim OFC-4/8/12 G.657A1 / G.657A2 microcables with an LSZH yellow sheath, and multi-loose-tube OFC-12/24/48/72/96/144 G.652D FMD cables with HDPE sheath, FRP central strength member, water-blocking yarn and ripcord. Compact sizes and low-friction outer surface enable air-blowing distances up to 2 km with a CBS air-blowing set. Manufactured in accordance with IEC 60793, IEC 60794-5, ITU-T G.650/G.652/G.657 and EIA/TIA 598.
