RE: [WIRELESS-LAN] Single mode/single fiber connectivity options?
This essentially uses a CWDM like technology. Here is a similar product from Fluxlight: http://www.fluxlightinc.com/cat.php?cat=Cisco%20BIDI%20SFPscat2=SFPs%20 and%20GBICs These are rated for about up to 6 miles I believe. We have a link about to go up that is about 6 miles from campus using this, we've tested it and it worked well. I believe that we had about -14 to -15 dBm on the meter from these when we tested over the link. --Joe -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Frank Bulk - iName.com Sent: Friday, January 16, 2009 3:03 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Single mode/single fiber connectivity options?

Hi, I need to connect a building to our campus that is about 5-6 miles away. We will be leasing a single mode fiber connection to the location, and connecting a Cisco 3750 stack back to our Core 6509. Using a single fiber instead of a dual fiber connection will save us $12,000/yr. In looking of ways to do this (connecting GBIC in the core to the SFP in the 3750), I came accross the following: http://www.championone.net/pdfs2/SingleFiber40km.pdf They have a single mode/single fiber GBIC that can connect to their single mode/single fiber SFP. I called the company, and they said the applicaiton should work, we would just need to add an antenuator to the fiber connection since it is rated for 40 km. Has anyone used this company, or have other ways of making this connection.

RE: [WIRELESS-LAN] Single mode/single fiber connectivity options?
We've used a similar product from Cisco (actually, it may very well be the exact same product): WDM-1300-1550-S and CWDM-SFP-1550. We have not had a problem with it since we installed it this summer. You may not need an attenuator. The minimum cable length for things like this are surprisingly accommodating.
