WIPO Patent Application WO/2020/116013
Kind Code:
A1
Abstract:
Provided is a relay device for relaying N (N is an integer greater than or equal to 2) optical signals, transmitted by a first space division multiplex optical fiber, to a second space division multiplex optical fiber. The relay device is provided with: a first connection means for connecting the first space division multiplex optical fiber and the N single core optical fibers; a second connection means for connecting the N single core optical fibers and the second space division multiplex optical fiber; an amplification means for amplifying, between the first connection means and the second connection means, the N optical signals; and a delay adjustment means for adjusting, between the first connection means and the second connection means, transmission delay of each of the N optical signals.
