Product Introduction
POTEL®CONEXESS® G.657.B3 bending insensitive single-mode fiber has better bending resistance and can be fully compatible with different wiring systems in various installation environments of backbone networks, metropolitan area networks, access networks, and indoors.
Product Application
G.657.B3 has excellent bend resistance and low water peak, with additional attenuation less than 0. 1dB/turn at a 5mm bending radius, suitable for narrow and complex wiring environments; applicable to various structured optical cables, indoor cables with small bending radius requirements, small-sized cables, and optical fiber devices.
Product Features
• Strong compatibility
• Excellent protective coating and superior peel ability
• Ca n be used in various optical cables including ribbon cables and invisible cables, extremely low macro bending loss can meet various complex indoor wiring applications
• High fatigue resistance parameters ens re long service life even at small bending rad ii
• Precise geometric parameters ensure low fusion loss and high fusion efficiency.
