  • 10GBase-X mapping in OPUk

    From Michelot@21:1/5 to All on Sat Feb 27 10:44:22 2016
    Bonsoir Huub,

    In the table IX.1 of G.709 (02/2012) we can see 1000Base-X mapping in OPU0 after TTT + GMP, but not the 10GBase-X mapping.

    Perhaps it's not very used by operators.

    Is 10GBase-X could not be mapped in OPUflex of 10 x 1,25 Gbit/s?

    Similarly, would it be possible to map 1000Base-X in OPUflex of 1,25 Gbit/s (also TTT for the TS capacity in OPU2)?

    Cordialement,
    Michelot

    Indeed.

    Is 10GBase-X could not be mapped in OPUflex of 10 x 1,25 Gbit/s?

    10GBASE-X (LAN) uses similar coding methods as 10GBASE-R but is only
    used in the definition of 10GBASE-LX4 so the same mapping can be used
    as 10GBASE-R.

    The mapping of 10GBASE-R is in recommendation G.Sup43.

    Similarly, would it be possible to map 1000Base-X in OPUflex of 1,25
    Gbit/s (also TTT for the TS capacity in OPU2)?

    Yes, that is possible.

    Best regards, Huub.

    Bonjour Huub,

    10GBASE-X (LAN) uses similar coding methods as 10GBASE-R...

    10GBASE-X uses a 8B/10B channel coding. For the 4 optical lanes, we have a rate of 12,5 Gbit/s.

    10GBASE-R uses a 64B/65B channel coding. We have a rate of 10,3125 Gbit/s.

    Cordialement,
    Michelot
