This is a new install with 144 strands.
Make sure you ask them for a copy of the fiber "characterization" for both 1310nm and 1550. Make sure you get both loss per kilometer and dispersion. With that said, a 80km GigE (ZX) for your data box should make it with no problem with plenty of margin, assuming that the 40 mile is actual fiber distances.]]> http://www.dslreports.com/forum/remark,20466457 Sun, 11 May 2008 18:15:13 EDT Re: Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20463157 Raven1275 : This is a new install with 144 strands. None have been lit yet, so we will have full use of the fibers. What are your recurring charges on the 50 mile run?]]> http://www.dslreports.com/forum/remark,20463157 Sat, 10 May 2008 21:23:58 EDT Re: Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20459770 Rhaas : 40Mi is a pretty good stretch on a single shot (very doable though). One catch though without know their network is if you happen to be mid-span and they by chance are doing any multiplexing/regeneration/amplification they may not have an unlit end-to-end fiber. We ran into this situation, we have redundant OC-12 connections (4-fibers)into each end of our network (50mi's apart) from the a company and we wanted to shoot our own light across a pair of the fibers we were utilizing. We found out that they were multiplexing the run and therefore there wasn't a true/unbroken fiber end to end. We ended up just purchasing a ptp ds3 to interconnect the 2 ends..]]> http://www.dslreports.com/forum/remark,20459770 Fri, 09 May 2008 23:22:51 EDT Re: Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20454904 keefe007 : Dark fiber isn't cheap at all. I'd estimate you'd be looking at anywhere from $5000 a month to $XX,XXX a month for that.]]> http://www.dslreports.com/forum/remark,20454904 Fri, 09 May 2008 01:16:36 EDT Re: Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20454098 Raven1275 : Thanks for the input guys. This is very helpful.

What we are looking at is getting two strands of fiber dropped to our pop. We will provide the electronics at the endpoints. Total distance is about 40 miles passing 3 rural villages. As for speed, I am assuming that will be dependant on what we choose for electronics. This is strictly a point to point fiber connection, no ring, no electronics and no bandwidth.

The broad questions are simply from lack of experience in the use of fiber connections. We are hoping the fiber is a better alternative to high capacity licensed backhaul radios and will be affordable.]]> http://www.dslreports.com/forum/remark,20454098 Thu, 08 May 2008 21:53:42 EDT Re: Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20452891 EMC_guy :

A forum member has some experience in building dark fiber networks overseas - I will ask him to elaborate on the technical aspects. Anyway we briefly explored feasibility of a private fiber run to the nearest town (Perth, ON) which has existing fiber PoP. Essentially you have to string "hybrid aerial" fiber that comes from China on existing and new poles.

The material and labour costs are reasonable BUT ... you have to negotiate per-pole rental fees with a whole bunch of farmers and rural municipalities. That will determine your recurring cost for the dark fiber run - the rest will be the bandwidth cost at the source where you connect - if they allow you to connect!

I am not familiar with your Island Pond, VT location but there is a massive capacity fiber run going through Burlington to Montreal.]]> http://www.dslreports.com/forum/remark,20452891 Thu, 08 May 2008 17:18:55 EDT Re: Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20452364 joshg409 : We have a provider in a neighboring town that provides dark fiber. We have one or our clients using the dark fiber which is basically a cross town link with two endpoints. Single Mode Single Fiber, we provide the transceivers.

Long Haul fiber?
Metro Fiber?
How many Miles?
What market?
What speed?
Ring or no Ring?

There are many variables involved unless you like apples to oranges comparisons.]]> http://www.dslreports.com/forum/remark,20452297 Thu, 08 May 2008 15:32:26 EDT Dark fiber - recurring charges http://www.dslreports.com/forum/remark,20451941 Raven1275 : Hi All,

I am attempting to research pricing for the lease of dark fiber circuits. We are considering both rental of existing fiber and also building some of our own which could potentially be sub leased. It has been difficult so far trying to get access to pricing information, so if any of you folks happen to use or lease these types of connections, I would truly appreciate some input on what to expect and what to charge.

Thanks...]]> http://www.dslreports.com/forum/remark,20451941 Thu, 08 May 2008 14:18:00 EDT
