The Free Bending Optical Cord removes the frustration of fiber breaks that occur during wiring. The Free Bending Optical Cord improves the efficiency of wiring in offices and homes. The free bending cord is composed of two parts; Hole-Assisted Fiber (HAF) and Optical Connector with Shutter. The Hole-Assisted Fiber developed by NTT R&D can bear bending and doesn't cause deterioration in communication. The optical loss is less than 0.1dB with a 2.5mm bending radius and 10 turns. The SC connector has a shutter to prevent light-transmittance and dust. Also, a cleaning cloth is pasted on the ferrule side of the shutter. This saves the effort of cleaning the connector before connecting to outlets. Taking advantage of HAF (Hole-Assisted Fiber) technology, which allows a bending radius of 2.5mm, NTT-AT offers Short Boots SC Connector.
