NOTE:
NOTE: Multi Mode Duplex should connect same Multi Mode Duplex
wavelength, like 850MM should connector MM 850nm, couldn't connect MM
1310.
Single Mode duplex should connect same Single Mode wavelength, SM
Duplex 1310 should connect SM 1310 Duplex, couldn't connect SM Duplex
1550NM.
Duplex couldn't connect Simplex BIDI.
Simplex BIDI only connect simplex BIDI U connect D, D couldn't connect D U
couldn't connect U.
Single Mode(SM) couldn't connect Multi Mode(MM).
