    Standards:

    • Unless otherwise specified in this specification, all requirements shall be mainly in accordance with the following standard specifications.
    • Optical fiber:ITU-T G.651、G.652、G.655、G.657 IEC 60793-2-10、IEC 60793-2-50
    • Optical Cable:IEC 60794-1-2、IEC 60794-5
    • Note: It is recommended that the structure of 2 fibers unit consist of 2 filled fibers, for it is proved that this structure is better in the blowing performance and the fiber separability than that of one with zero or one filled fiber
