YOFC FullBand® Ultra low loss single-mode fibre is based on 9.1μm MFD that same as most standard single-mode fibre, benefit for it seamless compliant with existing network. It fully meets the demands for transmitting signal with high speed, high capacity and extended networking distances over one single fibre. YOFC FullBand® Ultra low loss fibre complies with ITU-T G.652.B and G.654.C.
Due to the process innovation and technical breakthrough, Ultra Low Loss Single-mode Fibre has the following features and advantages:
|
