We had a level3 install for a client in the data center a few months back, they brought in three diverse rings/gear sets from west, east and south ends of our data center. The client is buying multiple 10 GigE for their mpls networks. We also have 2 x 10 gig to Atlanta as well as our DIA for BGP with them on this gear.
The pictures show there 4 rented racks from us as well as there full install.
The gear is fully optical DWDM transport switch, it is configured with 40 x 10 gigE in each chassis. Since all switching is optical between the cards, this gear is supposed to drop latency drastically.
Another member posted his L3 install and I wanted to post to show how across the board there installs are.
have fun. |

canada | Clean work... Like the EV power equipment, too... Too bad my company won't use them.
Thanks for the post! |

Absolutely B-E-A-utiful install. |

The EV stuff is great, we see it used more frequently lately.

Need a kleenex after looking at those pics.
That is just insane! |

I do all of AT&T's installs, and use Valere in 9 out of 10 installs. The only bad thing is the lack of ringing in their bulk power supplies... Well, they may have them, but not in products on ATT's "approved" list.
They're clean, straight forward and rock solid...
EDIT: Grrr, forgot to mention that I HATE that shelf you're using! Honestly, there are as many breakers on LVD as not! For this reason I have to use the double landing IPS, and they're like lifting a VW bug into the rack!!! |

said by goracknet:Since all switching is optical between the cards, this gear is supposed to drop latency drastically. That will be one "side effect" of an all optical system, but its not the particular purpose for doing it that way.
Quite simply, it is more flexible to (de)multiplex wavelengths of light using prisms and switch them around using e.g. MEMS mirrors than it is to convert a wavelength to electrical signals and back again (OEO).
All optical allows wavelengths to carry signals at any bit rate, any protocol, any modulation and the only component of the system that needs to be specific to any of these are the transponders that sit on either side of a wavelength.
If the line system just works with light, it can be fully agnostic to anything that it is transporting. An OEO system will have some limitations as its electronics will be designed to support only a certain number of signal types. |

kudos:4 | Indeed. This kind of kit is typically used for long haul where running hundreds of fibre cores isnt efficient, or maybe really busy metropolitan networks/routes where physical fibre is short.
Its not something you would really use for a few circuits across town on an average day, though there are smaller systems that are better suited to this kind of scenario. |

| Makes sense, as only large/top level networks have a real need to multiplex and such.
Our internal network is all fiber, and looks like a busier version of the last picture due to the use of the SFP blades rather than the old style GBIC (completely populated). |

| This is a set of three rings linking Atlanta to Jacksonville, FL. They are pushing 6 cards of 40 channel sonet, ethernet or whatever they desire.
We have a few channels from them to 56 Marietta. |

kudos:9 | That's a lot of capacity you have there. We are only pushing an OC-12 line with no WDM, but then again Level 3 is Tier 1. Why the decision to go with Huawei? |

sk1939, cheaper...
Level3 on their inter-continental long-haul (Denver to Salt Lake City through Donner Pass to Sacramento and Denver to Boise to Seattle) is using Infinera/Ciena/NSN and Huawei...
Both Infinera and Ciena can do 8 Terabits per inter-continental fiber pair and 100G DWDM.
The new Ciena stuff can do 8 to 24 terabits with 500G wavelengths at a time (yes overkill but some fortune 100's need to move 500G from their San Jose distribution to their Chicago distribution blah blah blah) in 2-5 years...
NSN is also good and has 100G technology.
Fujitsu/NEC is mostly resellers of transmode stuff.
(they got beat in the tera-bit space)...
It's a terabit race.

Huawei: »www.huawei.com/en/static/hw-076756.pdf
The point of moving terabits of global capacity from Los Angeles to New York.
The 5000km is important for submarine stuff like San Jose to Shanghai/Hong Kong/Tokyo.
Singapore to London via Suez Canal, Cairo and Mumbai.
Beijing to Moscow and London (land route).
