PASSIVE [D]WDM... Like, Cisco 15216.
We're looking to get glass between three buildings, and looking closely at the 15216 (passive WDM, ie, a prism). A couple of rambling questions, that perhaps folks here have experience with. First, has anyone had experience with ITU Grid Optic GBICs? Do they even exist? Second, does anyone know of a 'back-box' that will take standard 1310 or 1550 nm signal, and 'convert' it to an ITU grid? Any pointers, help, or a kick in arse would be appreciated. -- Alex Rubenstein, AR97, K2AHR, alex@nac.net, latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --

Cisco sell "CWDM" GBICs, which are sort of on ITU wavelengths, but with a wider spacing. I've not tried them to see if I can use them with the 15216 but "sparsely".

I'm currently using the 15454 to wavelength convert OC48 signals, but have not to date seen a black-box wavelength convertor - I would also be interested to know if such a beast exists. I think if you want to do this, you're stuck with the Metro 1500 (or equivalent from someone else), which becomes very expensive quickly.

Transmode <http://www.transmode.com> has both 1.25Ghz and 2.5Ghz units with where you pretty much can pick and choose your optics from 850nm MM, 1310, 1510, 1530, 1550 and 1570nm when you order. This is not a complete ITU grid from what I can find (I don't know exactly what ITU grid is but I found some specs) but rather for CWDM use. There should be quite a few manufacturers making units like these, I know the MRV people does it as well (or some company within MRV). -- Mikael Abrahamsson email: swmike@swm.pp.se
