    High Speed Market Drivers

    BBC iPlayer

    Higher quality than YouTube

    10 x longer viewing

    30 x more bandwidth

    Internet Video

    YouTube uses 200TB daily

    - as much as the entire

    Internet did in 2000.

    Video Calling

    10x more bandwidth as we

    move from phone to video

    conversations

    Mobile Data & Video

    Apple sells 1 million iPhone

    4S in 1 day, all supporting

    video features.

    HD TV

    Upgrades to HDTV will

    increase IPTV bandwidth

    five-fold

    Wireless Backhaul

    80% Operators: strategy to move to all-IP/Ethernet Backhaul

    82 %Ethernet Backhaul connection by 2015

    $6.4B Ethernet Backhaul 2011 (93%) 50% of failures take place in the backhaul

    1/3 OPEX technical operation

    Ethernet offers compelling economics for Mobile Backhaul and

    creates a demand for higher bandwidth at the core

    High Speed Optical Transceivers

    1H/2011 100G revenue shipments totaled $35 million

    From 2010 through 2015, the total market, including 100G, will grow at a CAGRof 16% to reach $2.6 billion in CY15

    Technology is now commercially available from most NEMs: Ciena, NSN, ALU,

    ZTE, Cisco
