Future-proofing and Fiber Architecture

Johan Henæs, CTO of INS Communications, discusses the evolution and future of fiber architecture, emphasizing the need for flexible and scalable network designs. Drawing on historical developments in passive optical networks (PON), such as TPON and APON, Henæs stresses the importance of adapting to unpredictable service demands. He highlights the advantages of WDM-PON as a solution for modern broadband access, promoting collaboration through the WDM PON Forum, which fosters innovation among service providers and technology vendors to enhance network capabilities.

Presentation Transcript

  1. Future-proofing and Fiber Architecture Johan Henæs CTO INS Communications johan@ins.no

  2. Electronics Engineer • Network design and implementation • CTO / VP Sales for Optical component company working on WDM-PON • Initiator of GIGAWAM project • Recently established System Integrator INS Communications in Norway

  3. “To be ignorant of what occurred before you were born is to remain always a child.” Marcus Tullius Cicero – 106 BC - 43 BC

  4. History • 1987 : BT start developing and rollout of TPON – Telephony on Passive Optical Network • 8x16 split in the field • 128 end users served Telephony with a 64kbit ISDN channel pr. Subscriber. • Broadband upgrade planned via B-IDSN (ATM) • 30.000 subscribers installed

  5. 90’s : • APON – ATM-based, but 32 split • Later ATM dies • July 2003 : BT starts replacing TPON with “Copper Overlay” (ADSL rollout) • Project ends late 2005 • (Similar project – OPAL Early 1990’s) • Deutche Telekom forklift-upgrade 200k users

  6. What have we learned? • Services cannot be predicted • Network design and technologies need to offer flexible and scalable platform for tomorrows services • Why build OSP that can only support FTTH ? • B2B • Wireless backhaul • CO Consolidation • NG-PON2 will be deployed within 5-10 years, Change to OSP needed • (European deployments mostly P2P)

  7. WDM-PON an attractive solution • - Best Performance BW vs $ Today • - Symmetrical Bandwidth (P2P) • - Scales Beyond 100MBPS, 1GBPS, 10GBPS pr User • - No change to OSP the next decades • WDM Already in Core / Metro • 10% OF P2P OPEX + save fiber cost • = Combines P2P and PON

  8. WDM PON FORUM WDM PON Forum overview / objective • The WDM PON Forum Group is an interest group of services providers, equipment suppliers, component vendors and analysts to work towards a common goal of providing WDM technology based broadband access networks. • The goal of the WDM-PON forum is to provide a resource for researchers, component and equipment suppliers, carriers, and other parties interested in passive optical networking technologies that utilize dedicated wavelengths as a method to provision services in access networks and to promote and advance the technologies required to enable cost-effective wavelength division multiplexing in Passive Optical Networks. Group located onLinkedinunder group “WDMPON Forum” • http: www.linkedin.com/groups?gid=2025479&trk=myg_ugrp_ovr • WDM PON Forum will be extended 2010 to www.fiberin.com Current Group Member status • 160+ members • Carriers / vendors / Media / analysts www.fiberin.com
