Abstract
Disclosed is a multi-core optical fiber block having a block base and a cover, each of which is formed having a tree-structured groove array, so as to allow respective optical fiber arrays to be seated in the corresponding respective groove arrays. The groove arrays comprises first sub-grooves having depth and pitches decreasing in magnitude as approaching from an input end of the block to an output end, and second sub-grooves formed alternately between the first sub-grooves and having the depths and pitches increasing in magnitude as approaching from the input end of the block to the output.
Claims13
A block base having a groove array to allow an optical fiber array to be seated in the groove array, the groove array comprising:
- first sub-grooves having a depth and a pitch decreasing from an input end of the block base to an output end of the block base;
- and,
- second sub-grooves formed alternately between the first sub-grooves and having a depth and a pitch increasing from the input end of the block base to the output end of the block base.
A multi-core optical fiber block having groove arrays, comprising:
- a block base formed with a first tree-structured groove array on a top surface thereof to allow an optical fiber array to be seated in the first groove array;
- and,
- a cover formed with a second tree-structured groove array on a bottom surface thereof and aligned with the block base to cover the optical fiber array.
A method for aligning a multi-core optical fiber block having groove arrays, the method comprising the steps of:
- (a) aligning a first optical fiber array on a block base having a tree-structured groove array;
- (b) aligning a cover having a tree-structured groove array with the block base to cover the first optical fiber array, thus forming a plurality of cavities therebetween;
- and,
- (c) inserting a second optical fiber array into the cavities formed between the first optical fiber array and the cover.
A method for aligning a multi-core optical fiber block having groove arrays, the method comprising the steps of:
- (a) aligning a first optical fiber array on a first block having a first tree-structured groove array;
- (b) aligning a second optical fiber array on a second block having a second tree-structure groove array;
- and
- (c) aligning the second black with the first block base to cover the first optical fiber array.
