C/D[WDM]
Anyone have any opinion on a user friendly and low-to-mid-priced CWDM or DWDM system? We need to take one pair of dark fiber and get about 5-6 10G ports on both sides. This is the info that the DF provider has given us on the route: Operating Wavelength: 1310/1550nm Maximum Attenuation:0.35 dB/km for 1310 wavelength 0.25 dB/km for 1550 wavelength Any suggestions would be tremendously helpful. thanks, -Drew

This should fit the pricerange: http://www.cubeoptics.com/passive_components.php Haven't used them yet but know of one local operator that is using them and is very satisfied... -- *blap* On Wed, Dec 22, 2010 at 15:14, Drew Weaver drew.wea...@thenap.com wrote: Anyone have any opinion on a user friendly and low-to-mid-priced CWDM or DWDM system?

We are using a couple of CUBO's passive DWDM muxes @ DE-CIX. Work like a charm.

Re: C/D[WDM]
+1 All our dwdm backbone is CubeOptics powered. We have about 30 pairs of DWDM band-spliiters and muxes. The attenuation is the lowest we have seen on all the wdm muxes we have tested. The tech guys @Cube optics are really smart. You can also ask for a specific mux if you have a want THE MUX. You can buy CubeOptics muxes your eyes closed -- Raphaël Maunier NEO TELECOMS CTO / Responsable Ingénierie AS8218 On Dec 22, 2010, at 10:03 PM, Arnold Nipper wrote: On 22.12.2010 15:31 Danijel wrote This should fit the pricerange: http://www.cubeoptics.com/passive_components.php Haven't used them yet but know of one local operator that is using them and is very satisfied...

Re: C/D[WDM]
+1 on the CUBO recommendation. In addition to muxes, we've worked with them as a supplier of (Finisar) colored optics; our dealings have been extremely favorable on all fronts. -a

RE: C/D[WDM]
Yes, sorry I should've specified 10Gig-E and I would like to avoid using CWDM/DWDM optics if possible I would just like to use regular LR optics. thanks, -Drew -Original Message- From: Randy Bush [mailto:ra...@psg.com] Sent: Wednesday, December 22, 2010 6:35 PM To: Drew Weaver Cc: 'nanog@nanog.org' Subject: Re: C/D[WDM] Anyone have any opinion on a user friendly and low-to-mid-priced CWDM or DWDM system?

The common misconception is that, just because you're not installing colored optics directly in your router, something similar doesn't live elsewhere in your system, mingled with a number of OEO conversions. Neat packaging and pretty GUI is orthogonal to cheap, and you stated both as initial requirements, so you're probably best choosing one or the other. We may differ on levels of frugality, however I can't think of any active system I'd classify as cheap; at the base, you're looking at a 2x multiplier from something assembled with cubes, however you slice it... If you find yourself stuck with SFP+ interfaces, or partners who don't grok this stuff and require a conventional LR hand-off, perhaps a 2xXFP transponder is really what you're after -- feed your mux with the colored optics, and the other end with some LR (or SR, CX4, ...). MRV has some good products in this space. HTH, -a
