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 --
