With 1U high compact design, RTN 905 include 905 1A(1+0,Hybrid),905 2A(2+0/1+1/XPIC,Hybrid) and 905 1C(1+0,Packet).
It can independently construct a network or seamlessly work with RTN 910, RTN 950, or RTN 980.
RTN 905 provide 4 x GE(RJ45)+2 x GE/FE(o) or GE(e) SFP module+ 16 xE1 interface, 2x STM-1 interface(905 1C),and 2 x TDM cascading interface.
RTN 905 supports 12-grade modulation schemes, Range from QPSK to 1024 QAM, plus the additional QPSK Strong/16QAM Strong /512 QAM light/1024QAM light mode.
Strong and light indicate FEC coding strength.
Strong FEC improves receiver sensitivity by increasing error-correcting codes. Light FEC expands service capacity by reducing error-correcting codes.
