GMPLS for Photonic NetworksProvisioning Soft
Permanent Connection
  • The support of new photonic network architectures
    requires the introduction of a new management
    functionality within the photonic layer

    shall during the whole contract period comply
    with the values in 1-7 below. The values include
    effects of possible future splicing, repair,
    aging, etc.
  • Attenuation at 1550 nm shall be less than 0.25
    dB/km and should be less than 0.22 dB/km.
  • Bend losses shall not be accepted.

    be less than18.5 ps/nm/km.
  • Polarisation Mode Dispersion (PMDQ) shall be less
    than 0.50 ps/?km and should be less than 0.20
    ps/?km.
