Features: High precise concentrated fiber lens technology, which makes highly focused, greatly reduces the reflection of the beam on the inner wall, completely ensures the loss less-transmission of the optical signal, makes the sound quality clear, restores the sound quality, and maintains this signal integrity. Plugs is very convenient, can accurately aligns the optical signal and successfully transmit large data . Super heavy duty plugs, close to the fiber interfaces, is also very easy to-plugs. Lowloss broadband transmission performances. Long service life, very suitable for decorating dark lines. The body is soft.
