Anyone out ther ever see or hear tell of a device that will let you run two GBICs back to back wthout an associated switch and all the trimmings? Application is to convert a CWDM GBIC signal to a Multimode one. TIA, Vin
Sounds like you need a singlemode-multimode convertor, available from various places, cost around $600 Steve On Mon, 11 Aug 2003, Vincent J. Bono wrote:

Omnitron also makes these, but they're probably closer to the $1000 range. http://www.omnitron-systems.com/converters/converters.htm ----- Original Message ----- From: "Stephen J Wilcox" <steve@telecomplete.co.uk> To: "Vincent J Bono" <vbono@vinny.org> Cc: <nanog@merit.edu> Sent: Tuesday, August 12, 2003 6:31 AM Subject: Re: Gigabit Media Converter Sounds like you need a singlemode-multimode convertor, available from various places, cost around $600 Steve On Mon, 11 Aug 2003, Vincent J.

Highly unlikely that it'll do CWDM, at least at that price. Transmode (www.transmode.se) does converters to order, they'll fix things that'll do pretty much any to any (850 / 1310 / (1490-1610) in any combination) including 3R and management (which implies that you need ethernet onsite which might be tricky). I'd believe they're more in the $3k-$5k range with CWDM optics though. If you need OC48 that'll hike the price up even more. -- Mikael Abrahamsson email: swmike@swm.pp.se
Ahh sorry I didnt realise the intention was to run the CWDM itself thro it, I thought this was for the output Ok well I'm not an optics expert but I wasnt aware multimode was capable of carrying more than a single wavelength because of interference/dispersion effects etc Steve On Tue, 12 Aug 2003, Mikael Abrahamsson wrote:

It doesnt. From my understanding the initial poster wanted to turn a GE CWDM (for instance, 1570nm light) single wavelength signal into a multimode (50nm) GE signal. That's what I answered to anyway. -- Mikael Abrahamsson email: swmike@swm.pp.se

Thanks for all the links and help! The issue is cost and space, and all the products that will work seem to cost upwards of $3,000 and do a lot more than we need or take up a few rack units of space. I am probably going to build a small circuit to handle connecting two GBICs back to back. The pinout from molex was readily available and we can get CWDM GBICs these days for $400 or less and more normal frequencies for sub $150. Anyway, anyone who is interested in the final product send me email off-list and I'll keep you posted. -vb ----- Original Message ----- From: "Mikael Abrahamsson" <swmike@swm.pp.se> To: <nanog@merit.edu> Sent: Tuesday, August 12, 2003 7:21 AM Subject: Re: Gigabit Media Converter

Where can you get CWDM GBIC's for under 400. Most vendors charge 5-10x that price. Scott C. McGrath On Tue, 12 Aug 2003, Vincent J. Bono wrote:

Vinny, Would something like this work? http://www.mrv.com/product/MRV-FD-2GBIC/ You can populate it with GBICs to suit. Cheers, Mike
