CESNET a.l.e. Czech Educational and Scientific Network Long distance fiber connections in NREN, TF-NGN 2October 18, 2002 Customer Owned Fiber networks Networks using optical fibres constructed, bought or leased by some network users/customers Wide independence of Customer Owned Fiber (COF) networks on carriers Unique window in time for fiber assets or IRU Getting fiber means controlling the network Path to deployment of different wavelengths for different networks, lambda services, QoS on backbone, optical switching etc., when it makes sense COF networks are emerging chronologically from bottom of hierarchy to top

CESNET a.l.e. Czech Educational and Scientific Network Long distance fiber connections in NREN, TF-NGN 3October 18, 2002 Connections for WAN RENs Interconnection of REN segments by carier’s lambda services (e.g.: Starlight, CESNET, Pioneer, etc.) Interconnection of regional area REN’s lambda services (Ca*net4) Long distance owned or leased fibre, e.g.: –fibre owned or leased by a group of universities, etc. (UCAID, CENIC, SWITCH, CESNET, etc.) –fibre owned or leased by a group of RENs, etc. (CANARIE?, GEANT/DANTE?, Nordunet?, etc.)

CESNET a.l.e. Czech Educational and Scientific Network Long distance fiber connections in NREN, TF-NGN 4October 18, 2002 RENs using own or leased fibers Advantages given by Customer Owned Fiber (COF) networks are important for RENs Developing COF networks: –ORAN, I-wire, CalREN, SWITCH, CESNET, SANET, Pioneer, …. Prepared COF network: –National LightRail, USA (2003) …. –European fiber connections?

CESNET a.l.e. Czech Educational and Scientific Network Long distance fiber connections in NREN, TF-NGN 5October 18, 2002 Equipment and services for COF RENs Significant investments in LH/ULH optronics and ongoing maintenance are required Fiber leasing or maitenance of own fibers instead of carier services? Optronics vendors now are becoming aware (at least in USA) of the non-carrier (enterprise, RENs) market for their WAN gear

CESNET a.l.e. Czech Educational and Scientific Network Long distance fiber connections in NREN, TF-NGN 6October 18, 2002 PoP to PoP fiber lengths in COF REN Metropolitan lines < cca 80 km (e.g. COF RENs in Praha or Brno, etc.) Long hall (LH) lines: cca km (e.g. PEI, SWITCH, CESNET, etc.) Ultra long hall (ULH) lines > cca 400 km (e.g.: US National LightRail?) Air distances are 50 – 90% of this due to terrain profiles and fibre curves
