Document Type and Number:
WIPO Patent Application WO/2020/041931
Kind Code:
A1
Abstract:
Disclosed is a submarine network device, comprising an optical fiber set, a pump laser set, an erbium doped fiber amplifier (EDFA) set, a primary optical fiber coupler (CPL) set, and a secondary CPL set. The primary CPL set comprises N primary CPLs, and the secondary CPL set comprises N secondary CPLs, N being an integer greater than or equal to 3; the optical fiber set is used for connecting the pump laser set, the primary CPL set, the secondary CPL set, and the EDFA set; an input port of each primary CPL in the primary CPL set is at least connected to one pump laser; an output port of each secondary CPL in the secondary CPL set is at least connected to one EDFA; an output port of each primary CPL in the primary CPL set is connected to two different secondary CPLs, separately; two different secondary CPLs are spaced apart from one secondary CPL; an input port of each secondary CPL in the secondary CPL set is connected to two different primary CPLs, separately; two different primary CPLs are spaced apart from one primary CPL.
