Connect by two interconnect optical fiber cross exchanged, realize signal different layers transmission, but at this point, interconnection two servers transmission
Function is restricted, and the quantity of the server that can only be interconnected as interlayer, link reduces the (chain interconnected without same interlayer
Road), but the transmission in cabinet is unaffected；Fig. 5 is to use optical switch matrix, can flexibly select outbound course, realizes Fig. 4
In identical function, but increase device cost, and transmission direction can only alternative；Fig. 6, which is use, can detach wavelength and be
λ0Light filter, non-interfering output may be implemented, but be limited to wavelength, the effect of first layer and second layer interconnecting transfer
Rate may be restricted that (when the transceiver quantity more than one transmitted for rack room, the interlayer of Fig. 4, Fig. 5 interconnects
The parallel transmission of multi-wavelength may be implemented in structure, greatly improves the rate of transmission, and the mode of Fig. 6 then optimizes without this)；Fig. 7
