    • An optical cable incorporates at least one fibre with positive dispersion and at least one fibre with negative dispersion spliced together within the cable. In the simpler forms of the invention, the aggregate dispersion from end to end of the cable is close to zero. The cable is intended for use in repairing a dispersion- managed optical cable installation in circumstances where it is not possible to replace a short damaged lenght of cable along its original route and it is necessary to insert such additional lenght of cable that the dispersion balance of the system may be adversely affected. If required, the cable may be modified (with an aggregate dispersion different from zero) to make it possible to match the dispersion of the damaged cable length that was removed instead of neglecting it.
    • 光缆包括至少一个具有正色散的光纤和至少一个具有负分散的光纤,该光纤在电缆内部拼接在一起。 在本发明的更简单的形式中,电缆端部到端部的总体色散接近零。 该电缆用于修复色散管理的光缆装置,在不可能沿其原始路线替换短的损坏的电缆长度的情况下,并且需要插入额外的电缆长度,以使分散平衡 该系统可能受到不利影响。 如果需要,可以修改电缆(聚集体色散不同于零),以使匹配已被去除的损坏电缆长度的色散可以匹配,而不是忽略它。

    • Flexible joint which is used for the repair during the production of metallic tubes which enclose loosely inside them optical fibers, surrounded by a suitable filling material or for the connection of long lengths of the above mentioned tubes during the manufacturing of submarine cables which contain these tubes. The joint comprises a connecting metallic tube (6), which connects externally with overlapping at its ends the metallic tubes (3, 10) after splicing is performed between the optical fibers which they enclose and which are separated in bundles (1,2). The mechanical connection of the joint is achieved through plastic deformation of the over-applied connecting metallic tube by creating grooved rings (11) at the sections where it overlaps the metallic tubes to be connected (3,10). The water tightness of the joint is obtained by welding the ends (8) of the over-applied connecting metallic tube (6) to the external surface of the metallic tubes to be connected (3,10). In the case the metallic tubes carry a plastic coating (4), this is restored in the area of the joint (9, 5).
    • 柔性接头用于在金属管的制造期间进行修理,金属管在其内部宽松地包围光纤,由合适的填充材料包围或在制造包含这些管的海底电缆的过程中连接长的上述管 。 接头包括连接金属管(6),其在外部连接,金属管(3,10)在其端部之间重叠,在它们包围的光纤之间进行接合,并且将其分离成束(1 ,2)。 通过在与要连接的金属管重叠的部分(3,10)处产生开槽环(11),可以通过过度施加的连接金属管的塑性变形来实现接头的机械连接。 通过将过度施加的连接金属管(6)的端部(8)焊接到要连接的金属管的外表面(3,10)上来获得接头的防水性。 在金属管携带塑料涂层(4)的情况下,在接头区域中恢复(9,5)。
