transcievers/amplifiers for 150 km fiber run
by Fletcher Kittredge 12 Oct '08

12 Oct '08

We are looking to light a two strand fiber link of about 95 miles (or 150km). It would be worth a lot to us not to have repeaters. We are hoping for Gigabit Ethernet. Sonet is possible but a less attractive solution. Are there options for this sort of distance? The longest current link we have is about 65 miles. I understand the transmission characteristics of the fiber will effect distance of transmission. regards, Fletcher -- Fletcher Kittredge GWI 8 Pomerleau Street Biddeford, ME 04005-9457 207-602-1134

Paging Ultradns/neustar neteng

12 Oct '08

UltraDNS / Neustar netengs : There is a routing instability in one view of a small part of your network that¹s none the less making my phone blow up. (pdns4) Your noc guys didn¹t exactly get what I was trying to explain ; refer to SR 1-48803905 for some data. An off-list ack would be cool in any case; I have an unrelated curiosity or two I¹d like to throw at some neustar clue. tia, -jamie

lighting talks and the program committee
by Todd Underwood 11 Oct '08

11 Oct '08

<again wearing that chair of the nanog program committee hat> two quick reminders as many of us head towards LA for the conference: 1) there have been some excellent lightning talks submitted but there are still more slots availble than talks submitted. if you have an idea and can whip up an abstract by tomorrow and a talk by monday, you still stand an excellent chance of getting to present at this nanog. i've heard lots of good ideas that i have yet to see in lightning talks. so send 'em in! http://www.nanogpc.org/lightning/ has the information on how to submit talks. 2) many slots in the nanog program committee are opening up. the program committee is the group of 16 people responsible for recruiting and selecting the entire set of talks/presentations/bofs you see at nanog. most of you are *positive* you could do a better job than we have been doing. of that i have no doubt. so please submit your name to be considered for a slot. there is a certain amount of work involved (about 4 conference calls per nanog and the requirement to read/vote/comment on almost every submitted talk) but the rewards in fame and infamy are well worth it. more information is here: http://www.nanog.org/governance/elections/2008elections/ you can nominate yourself or someone else by sending mail to: nominations(a)nanog.org looking forward to seeing many of you in LA tomorrow. t. -- _____________________________________________________________________ todd underwood +1 603 643 9300 x101 renesys corporation todd(a)renesys.com http://www.renesys.com/blog
