Dean Shareski is a Digital Learning Consultant with the Prairie South School Division in Moose Jaw, SK, Canada. He specialize in the use of technology in the classroom. He holds a Masters of Education in Communications and Technology through the University of Saskatchewan and is also a sessional lecturer for the University of Regina. Since 2004 he’s been immersed in understanding what the Read/Write Web is all about and how the new shape of knowledge changes how we all learn.
Dean will be joining us with a presentation titled “When You’re Not the Smartest Person in the Room“. Dean’s topic will be “networked learning”, i.e. how educators leverage Web 2.0 tools to build relationships that enable new forms of learning to happen for themselves and their students. Dean has a great sense of humor and a presentation style that is both entertaining and informing. He has a knack for visual design that is inspiring.
Everything you need to know about Dean can be found at his blog Ideas and Thoughts.
It looks like we got a successful recording! Thanks to everybody that learned along with me. I’m still getting my feet wet with Adobe Connect and learn stuff each time I do one of these sessions!

We are working on a list of commonly used terms in the networking world. Please use the comments below if you have suggestions for additional terms or concepts.
Amplification: Boosting optical signal power without improving overall signal shape. Less expensive than regeneration.
Break-Fix: Finding and repairing fiber cuts anywhere along a path.
Build: Install fiber, usually by trenching fiber into the groups or attaching to telephone poles.
Characterization, Testing, Shoot the Fiber: Test fiber for continuity, signal loss over distance, and possibly other performance traits.
Conduit, Innerduct: Conduit laid in the ground during fiber build to house fiber cables. There may be extra capacity or additional empty conduits buried for running additional fiber in the future.
CWDM, DWDM: Course (or Dense) Wave Division Muliplexing: A way to create multiple virtual paths over just one pair of fiber. Generally “Coarse” for 2-8 paths, “Dense” for 9-40+ paths.
Dark Fiber: Unused fiber optic cable. Dark because it has no optical hardware (lasers) attached yet.
Hand Hole: Like a small man hole. A covered chamber that allows access to fiber cables and conduits for splicing or pulling new cable. May be installed in sidewalks with visible covers or just underground in unpaved areas.
Huts: Small buildings with power and HVAC located periodically along long haul fiber paths where optical hardware can be placed to regenerate or amplify signals on the fiber.
Lambda, Wave, Color: Individual discrete virtual path in a CWDM or DWDM system. May be listed with capacity, “10 Gig Lambda”.
Lateral: Short fiber build, typically from longer fiber run in street to a building, between buildings, or even between two areas in a single building.
Light (verb): To light dark fiber. Installing optical hardware on dark fiber, making it no longer “dark”, but rather “lit”.
Lit Services: Usually refers to telco provided services which could be circuits or lambdas. Someone else owns the optical hardware.
Local Loop: Generally cross town laterals that connect from long haul fiber path to the building (POP).
Locate: Doing locates. AKA Diggers Hotline. Finding and marking specific location of fiber optic cable in preparation for digging.
Loss Budget: Dictates how much a signal can degrade over distance before it can no longer be reliably received on the other end. Amplification and regeneration are used to extend beyond these distances.
Optical Hardware: Hardware specifically used on dark fiber to create paths/circuits which may then connect to standard switches or routers.
OTDR, Power Meter: Test equipment used to characterize (test) fiber optic cable.
Regeneration: Retransmit fresh optical signal to eliminate degradation of signal shape. More expensive than amplification.
Transponder: Color specific laser interface in optical hardware. May be in the form of installable cards or may be build into chassis.
WIMAX: A technology that provides wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and fully mobile internet access. The technology provides up to 10 Mbit/s broadband speed without the need for cables.
Join us on Thursday, January 21, 2010 at 2:00pm CST for a presentation & discussion with David Kieper (UW-Green Bay) and Craig Stephenson (WiscNet) about our MasStore project.
