Patent ID: 8538266

Claim:
An optical fiber hub for transmitting light signals between an upstream host and a plurality of downstream peripherals, the optical fiber hub comprising: an upstream port comprising an input and an output, the input configured for receiving a light signal from the upstream host; a light splitting element optically communicated with the upstream port, the light splitting element configured for splitting the light signal into N light beams; N downstream ports optically communicated with the light splitting element, each of the downstream ports comprising an input port and an output port, the output port configured for transmitting and forwarding one of the N light beams to a corresponding downstream peripheral, the input port configured for receiving a light signal from the corresponding downstream peripheral, wherein N is an integer which is equal to or greater than 2; a light converging element for converging light signals from the N downstream ports and transmitting the converged light signals to the output of the upstream port; and a reflection element, the reflection element comprising a first reflection surface and a second reflection surface, the first reflection surface configured for reflecting the light signal from the input of the upstream port to the light splitting element, and the second reflection surface configured for reflecting the converged light signals from the light converging element to the output of the upstream port; wherein the light splitting element comprises (N−1) splitting members comprising a first splitting member, a second splitting member, a third splitting member, . . . , a (N−1)th splitting member, the first splitting member of the N−1 splitting members is configured for splitting the light signal from the first reflection surface into two light beams, and respectively transmits the two light beams onto the second and the third splitting members of the (N−1) splitting members, the second splitting member and the third splitting member are respectively configured for splitting the light beam reflected on itself into two light beams, it is analogized that, each of the (N−1) splitting members is configured for splitting the light beam reflected on itself into two light beams such that the light signal from the first reflection surface is divided into N light beams.
