Joint box is used for direct joint or multi-branch joints of ADSS, OPGW & other optical cables. It is qualified for superior environmental adaptability & reliability in the overall structure of product, catering to optical cable communication system; its installation program is easy, helpful to rapid & convenient assembly; the loose room of rotating disc have the winding of rotating disc more convenient on which the adequate bending semi-diameter of optical cable avoids consumption of optical cable joint from the stress, keeping normal transmission characteristics of optical cable.

Cannonball type plastic connector joint box: used for ADSS and ADSS cable connection, the maximum capacity of fiber is 96 core.

Cannonball type metal joint box: It has the advantages of high mechanical strength, good sealing performance and strong corrosion resistance. It can be repeatedly opened, expanded, repaired, multiplexed, etc. The maximum fiber capacity is 144 cores. The additional loss of the fiber tray is ≤0.01Db, and the bending radius of the fiber=45mm is fixed by the special clamping method, which effectively prevents the cable from being damaged and the installation operation is extremely convenient.
