10 GE WAN PHY status?
Hi, I'm currently looking into how to best integrate 10G lambda lines into a network. The two obvious ways are via "native" SDH/SONET or via 10 GE WAN PHY, but the latter isn't available on any router platform so far. What I like with 10GE is that its possible to run a ring segment via L2-switches on each end and connect to them via multiple L3-devices. So you can basically run a 10G line with a redundant pair of routers on each line concurrently and without any static bandwith partitioning. Am I missing something? Sine none of the long distance providers I talked with so far can provide 10 GE LAN PHY as client side interface, I'm currently looking for L2-switches that can perform this conversion between LAN and WAN PHY, but I only found the Nortel Passport and the Force10 E-Series, both AFAIK quite pricy product lines. Last informations I got about WAN PHY XENPAKs was that most switch manufacturers can only provide them sometime in Q1/2005 (but I read the same in an article on this list about Q1/2004 :] ). Are there other products I missed? Are there XENPAKs already available which work with main stream switch manufacturers although they don't sell them themselves so far?

I know that Extreme Networks already is shipping XENPAK enabled switches. The max for a single fiberspan according to the specs = 40Km. ( depending on the quality of the fibers and the attenuation. ) They have blade's for the Blackdiamond 68 series and the BD10K and the Summit400 has 2 slots where you can fit them in. http://www.nwfusion.com/news/2004/0202extreme.html http://www.extremenetworks.com/LIBRARIES/prodpdfs/products/BD_XENPAK_DS.pdf The only downside that I've seen on the Summit400 is the limited EAPS support to 1 EAPS domain.. but if you design your network correct you can get away with it. Other than that .. they look like a great ( not too expensive ) way to setup a Metro layer2 network.

almost all switch vendors sell xenpak solutions, but no wan phy xenpaks :] (or did I miss something on the Exterme references?) tschuess Stefan -- Stefan Mink, Schlund+Partner AG (AS 8560) Primary key fingerprint: 389E 5DC9 751F A6EB B974 DC3F 7A1B CF62 F0D4 D2BA

Correct, Extreme doesn't sell WAN PHY Xenpaks. On the other hand they don't code their Xenpaks so WAN PHY xenpaks work in their equipment, although it's not supported. -- Mikael Abrahamsson email: swmike@swm.pp.se

mhm, I'm still reluctant to use such a combination in a production network if I don't have an officially supported fallback. But having a look at it doesn't hurt :] Any pointers to vendors of wan phy xenpaks? tschuess Stefan -- Stefan Mink, Schlund+Partner AG (AS 8560) Primary key fingerprint: 389E 5DC9 751F A6EB B974 DC3F 7A1B CF62 F0D4 D2BA

Grateful for any pointers or experiences...
Most of the current optical DWDM systems that operators use today [i.e. >2 years old] can't do it and its not just a connector issue. A lot of new optical systems claim they can do it and as operators role out next gen DWDM you will see this product get more widespread deployment, I suspect that will happen in the next 12 months or so.

definitely not, I guess the system basically must have an ethernet switch included which does the conversion and buffering between the faster (asynchronous transport layer) lan phy port and the slower (synchronous transport layer) wan phy port... Some metro DWDM systems (e.g. optera metro) can do it today, but I guess they couldn't do it either two years ago... tschuess Stefan -- Stefan Mink, Schlund+Partner AG (AS 8560) Primary key fingerprint: 389E 5DC9 751F A6EB B974 DC3F 7A1B CF62 F0D4 D2BA
