Abstract
The utility model discloses a PLC optical branching device comprising a packaging shell and a packaging cover body matched with the packaging shell. The PLC optical branching device also comprises an input end tail fiber and output end tail fibers. An optical branching packaging tube is disposed in the packaging shell. One end of the packaging shell is provided with an optical fiber entrance hole and the other end is provided with an optical fiber outlet hole group. The input end tail fiber penetrates the optical fiber entrance hole and is packaged in a sealed manner through a first sealing layer. The output end tail fibers penetrate the optical fiber outlet hole group and are packaged in a sealed manner through a second sealing layer. The optical branching packaging tube is connected with the packaging shell through a shock absorption layer. The two long side edges of the packaging shell are provided with parallel sealing grooves and the two long side edges of the packaging cover body are provided with sealing strips matched with the sealing grooves. The PLC optical branching device has the advantages that the layout of components is reasonable, the production is convenient, the influence of falling-in dust is eased, the service life is prolonged, the replacement efficiency and the using cost are reduced and the device is suitable for application and promotion.
