Product Introduction
G.657.A 1, this type of anti-bend single-mode fiber not only possesses outstanding anti-bend characteristics, but also exhibits excellent loss characteristics within the 1310 nm and 1550 nm dual-wavelength frequency bands, which helps to expand the coverage of the access network.
Performance highlights
● Gigabit broadband home
● 5G pre-network construction
● Big data center & computer interconnection
Application scenario
● Low loss &bending insensitive
● Two optional diameters:245 μm (standard) &200 μm (optional)
● Optimized MFD and precise geometric properties
● Compatibility with ordinary G.652.D
