  1. Dark fiber networks in the Nordic countries Heino Radmer, Optical Network Architect 10. marts 2014

  2. NorthernLightbackground and objectives • Move from a leased line to a dark fiber infrastructure • Accommodate the future demands for capacity • High-speed Internet • Lambda circuits • Private light path services • Deployment of an Optical Exchange • Equipment - Cutting edge technology • LH/ULH DWDM • Channel count above 64 x 10G • 40G ready • Multi Service Transport Platform – Optical Exchange (NOX) • Handel circuit and packet based traffic • Targeting User Controlled Provisioning (UCLP) • Fulfill these requirements without a substantial budget increase.

  31. Fiber - requirements • Fiber specifications • The Dark Fibre shall be specified according to ITU-T G.652 or ITU-T G.655. • For ITU-T G.655 the True Wave Classic shall not be accepted. • The attenuation at 1550 nm should not exceed 23 dB and shall not exceed 35 dB. • Seacable specs 23 dB and 26 dB • The dark fibre parameters of the installed cable 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/kmand should be less than 0.22 dB/km. • Bend losses shall not be accepted. • Seasonal variations in the fibre parameter shall not be accepted. • Connector losses shall be less than 0.5 dB. • Reflection shall at any point be below -40 dB. • Chromatic Dispersion at 1550nm (CMD1550nm) shall 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. • Fiber span shall not exceed 80 km

  32. Fiber - provider problems • Only here to make money • Documentation

  33. Fiber - solutions • Measuring setup • Understanding

  34. Fiber – solutions continued • Procedures • Plenty of talking • Understanding • More talking….

  35. Status • Scandinavian Ring (fiber): Live • Finland Link (fiber): Live • Amsterdam Link (fiber): Live • Moscow Link (OC192): early October • London Link (OC192): in planning • (new) Iceland Link (OC48): in planning • (new) WIDE and CSC+NORDUnet possibilities for pan-continental connectivity
