Description
YOFC EasyBand® Ultra bending insensitive single mode fibre combines two attractive features: excellent low macro-bending sensitivity and low water-peak level. It is comprehensively optimized for use in O-E-S-C-L band (1260 -1625 nm).
The EasyBand® Ultra's bending insensitive feature not only guarantees L-band applications but also allows for easy installation without excessive care when storing the fibre especially for Fibre-to-the-Home networks application. Bending radii in fibre guidance ports can be reduced as well as minimum bend radii in wall and corner mountings, the minimum bend radius can reach 5 mm. Moreover, it is still compatible with standard G.652.D single mode fibre, which ensures that it has low connection loss with standard single mode fibre (including fusion splicing and mechanical coupling, etc.) and high power-handling for increased access network capability and flexibility.
YOFC EasyBand® Ultra bending insensitive single mode fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.B3 including the IEC 60793-2-50 type B1.3/B6 Optical Fiber Specification.
Application
All types of fibre cables with different structures
High performance optical network operating in O-E-S-C-L band
High speed optical routes for Fibre-to-the-Home networks
Cables with extreme low bending requirements
Small-sized fibre cable and compact optical component
Application in L band (1565-1625 nm)
Process
YOFC optical fibres are manufactured using the advanced Plasma Activated Chemical Vapor Deposition (PCVD) process. Because of the inherent advantages of the process, YOFC fibres show ultra accurate refractive index (RI) profile control, excellent geometrical performance, low attenuation, etc. High performance bending insensitivity requires a special Freon-Downdoped-Cladding design to prevent the optical field to escape. PCVD is the optimal process to realize such cladding design effectively.
The optical fibre is coated with YOFC's proprietary dual layer UV curable acrylate. This fibre coating system provides the fibre with superior environmental protection. Designed for more stringent tight-buffer cable application, the fibre also performs perfectly in loose buffer constructions and demonstrates a high resistance to micro-bending. YOFC's proprietary coating offers very stable coating strip force over a wide range of environmental conditions with no coating residue on the bare glass fibre. In fibre ribbon constructions, this coating system exhibits excellent performance in 60 watersoak tests, exceeding 10℃ 0 days. The coated optical fibre has high and stable values for the dynamic stress corrosion susceptibility parameter (nd), which provides greatly improved fibre durability when used in harsh environments.
