Optical switch module and optical by-pass apparatus

An optical switch module, comprising:

• a housing having an accommodating space, a first sidewall, and a second sidewall, wherein the accommodating space is located between the first sidewall and the second sidewall;
• at least two first collimators located on the first sidewall, wherein each of the first collimators is configured to connect even number of first fibers;
• at least two second collimators located on the second sidewall, wherein each of the second collimators is configured to connect even number of second fibers, and the second collimators are respectively aligned with the first collimators;
• a relay located in the accommodating space and having a rotation support, wherein a fulcrum of the rotation support is located on a center line of the rotation support to define a seesaw structure;
• and
• a plurality of prisms located on the rotation support, wherein a first partial number of the prisms and a second partial number of the prisms are respectively located at two sides of the center line of the rotation support, and the rotation support is configured to enable at least one of the prisms to be in light transmission paths between a partial number of the first fibers and a partial number of the second fibers to refract optical signals of the partial number of the first fibers to another partial number of the second fibers.

An optical by-pass apparatus, comprising:

• a first optical transceiver;
• a second optical transceiver;
• a first multi-fiber connector optically connected to the first optical transceiver;
• a second multi-fiber connector optically connected to the second optical transceiver;
• and
• an optical switch module comprising:
• a housing having an accommodating space, a first sidewall, and a second sidewall that is opposite to the first sidewall, wherein the accommodating space is located between the first sidewall and the second sidewall;
• at least two first collimators located on the first sidewall, wherein each of the first collimators is configured to connect even number of first fibers;
• at least two second collimators located on the second sidewall, wherein each of the second collimators is configured to connect even number of second fibers, and the second collimators are respectively aligned with the first collimators;
• wherein the first optical transceiver connects the first fibers of a first partial number of the first collimators, and the first multi-fiber connector connects the first fibers of a second partial number of the first collimators;
• the second optical transceiver connects the second fibers of a first partial number of the second collimators, and the second multi-fiber connector connects the second fibers of a second partial number of the second collimators;
• a relay located in the accommodating space and having a rotation support, wherein each of two ends of the rotation support extends to a position between the aligned first and second collimators;
• and
• a plurality of prisms located on the rotation support and respectively between the first and second collimators, wherein the rotation support is configured to enable at least one of the prisms to be in light transmission paths between a partial number of the first fibers and a partial number of the second fibers to refract optical signals of the partial number of the first fibers to another partial number of the second fibers.
