Optical signals are transmitted via fiber optic cables. The cable ends have connectors that connect to fiber-optic adapters. The interface between a connector and its adapter typically creates unwanted signal reflections. These unwanted signal reflections are mitigated by including an eight degree angle-offset of one face of an optical fiber within the adapter itself, the other face of the optical fiber having no angle offset, and the adapter being contained within a rigid housing. The angle offset of the fiber optic face in the adapter is mated with a complementary angle offset of the optical fiber in the cable connector. Embodiments of the present invention avoid cable management issues presented by previous adapters that included flexible cable between its input and output the previous adapters being designed primarily as jumpers and not suitable for use in tight, crowded spaces.
1. Apparatus for operatively coupling an optical signal from a first optical cable to a second optical cable, comprising:
a rigid angled-to-ninetv-degree adapter for optical transmission, said adapter comprising:
a single and inflexible housing having both a first housing port configured to connect to said first optical cable and a second housing port configured to connect to said second optical cable; and
seamless optical signal transmission media in direct contact with both said first optical cable and said second optical cable, said media encapsulated by said housing and extending from said first optical cable connected to said first housing port to said second optical cable connected to said second housing port to provide a seamless optical path from said first optical cable to said second optical cable, said media having been configured so that an end of said media in said direct contact with said first optical cable is a flat surface oriented at approximately an eighty-two (82) degree angle to direction of transmission of said optical signal
and so that an end of said media in said direct contact with said second optical cable is a flat surface oriented at approximately a ninety (90) degree angle to said direction of transmission of said optical signal.
2. Apparatus, comprising:
a single and inflexible housing, containing rigid and angled-to-ninety-degree adapter means for operatively coupling an optical signal from a first optical cable to a second optical cable, said adapter means including:
a first housing port for connecting to said first optical cable and a second housing port for connecting to said second optical; and
a single optical fiber encapsulated by said housing and extending from said first optical cable to said second optical cable, an end of said optical fiber interfacing with said first optical cable being a flat surface oriented at approximately an eighty-two (82) degree angle measured from direction of transmission of said optical signal and an end of said optical fiber interfacing with said second optical cable being a flat surface oriented at approximately a ninety (90) degree angle to said direction of transmission.
