MODE DIVISION MULTIPLEXED PASSIVE OPTICAL NETWORK (MDM-PON) APPARATUS, AND TRANSMISSION AND RECEPTION METHOD USING THE SAME

摘要

A Mode Division Multiplexed Passive Optical Network (MDM-PON) apparatus includes: a non-mode selective multiplexer which includes a first end where three or more single-mode optical fibers are spaced apart from each other by a predetermined distance, and a second end where cores of the three or more single-mode optical fibers are tapered such that a gap between the three or more single-mode optical fibers is narrower than the predetermined distance while the three or more single-mode optical fibers are spaced apart from each other by an equal distance; an optical line terminal (OLT) which is connected to the second end through a few-mode fiber, and transmits a downstream optical signal; and three or more optical network units (ONUs) which is connected to the first end through the three or more single-mode optical fibers, and transmits upstream optical signals.

1. A Mode Division Multiplexed Passive Optical Network (MDM-PON) apparatus, comprising:
a non-mode selective multiplexer configured to comprise a first end where three or more single-mode optical fibers are spaced apart from each other by a predetermined distance, and a second end where cores of the three or more single-mode optical fibers are tapered such that a gap between the three or more single-mode optical fibers is narrower than the predetermined distance while the three or more single-mode optical fibers are spaced apart from each other by an equal distance, wherein the non-mode selective multiplexer outputs, to the second end, an optical signal mode generated by coupling optical signals received at the first end, splits the optical signals received at the second end into a number of the single-mode optical fibers, and outputs the split optical signals to the first end; an optical line terminal (OLT) connected to the second end through a few-mode fiber, and configured to transmit a downstream optical signal; and three or more optical network units (ONUs) connected to the first end through the three or more single-mode optical fibers, and configured to transmit upstream optical signals.
