Fiber-optic cable bundling for interconnecting datacenters

A fiber-optic bundle coupling apparatus comprising:

• a first coupling end configured to encapsulate a first fiber-optic bundle of at least 100,000 fiber-optic cables;
• a first rubber sleeve configured to be inserted into the first coupling end and to surround the first fiber-optic bundle;
• a second coupling end configured to encapsulate a second fiber-optic bundle of at least 100,000 fiber-optic cables to be spliced together with the at least 100,000 fiber-optic cables of the first fiber-optic bundle;
• a second rubber sleeve configured to be inserted into the second coupling end and to surround the second fiber-optic bundle;
• a strand separator configured to be inserted into an end portion of the second coupling end facing the first coupling end, the strand separator comprising at least 100,000 openings corresponding to the at least 100,000 fiber-optic cables of the first fiber-optic bundle, wherein each of the fiber-optic cables of the at least 100,000 fiber-optic cables is configured to be inserted into a respective opening of the at least 100,000 openings of the strand separator;
• and
• a locking mechanism configured to couple the first coupling end and the second coupling end to cover spliced areas of the first and second fiber-optic bundles after the first and second fiber-optic bundles are spliced together.
