Hot backup matrix of NGB (Next Generation Broadcasting) optical network

Abstract

The invention discloses a hot backup matrix of an NGB (Next Generation Broadcasting) optical network, belonging to the technical field of optical network transmission. The hot backup matrix of the NGB optical network mainly comprises optical transmitters, optical switches and a control unit. The plurality of sets of optical transmitters are connected with the plurality of sets of 1*2 optical switches respectively through optical fibres. The optical switches are connected with an optical transmission network through optical fibres. An optical transmitter is additionally provided and connected with 1*4 optical switches, which are connected with the plurality of sets of 1*2 optical switches respectively. The control unit is provided and is in control connection with the plurality of sets of 1*2 optical switches and the 1*4 optical switches respectively. The 1*4 optical switches and the plurality of 1*2 optical switches form an optical switch matrix. Because the optical transmitter and the optical switch matrix are additionally provided, the hot backup of N+1 optical transmitter equipment is completed. In the event of increasing low cost, the reliability is greatly improved.
