Bell Labs estimates a 560% growth in Metro traffic between now and 2017. (I'd wish my assets multiply the same ...)
How do we cope in Metro?
Let me repeat: 100G is poised to explode over the coming years.Estimates of 560% growth in Metro traffic until 2017. *source: Bell labs, Metro Traffic Growth, Dec 2013
What is your evolution path regarding the Metro?
Data center interconnect, driven by high capacity video traffic, HD and 3D TV. OTT traffic from Netflix, Social Media, You Tube will accelerate the need for bandwidth.
Much of the debate to date has been around long haul 100G, but the availability of 100G pluggable optics that landscape has changed. Infonetics was reporting in November 2013, "10G becomes the new 1G client port rate, requiring aggregation to 100G in the network".
There are options around how you carry those 100G ports, with two transmission windows, O band and C band, being available. You can now offer 100G, with reach of up to 60km, using standard LR4 optics.
- Grey - 1310nm - 100G LR4 transceivers can be used in the O band, assuming your switch supports them, and together with SOA preamplifier, you can reach distances of up to 60km.
- If you want to transport more than 1 x 100Gig you can use non FEC 100Gig DWDM transceivers -70km reach, without central location, for multiple 100G DWDM services.
Both options are proven to work with existing DWDM 10G with matching power levels on 10G / 100G paths.
Using Transceivers plugged into the switches and tuneable by end customer switch and no additional signal conversion or transponder cards being needed and for shorter distances, only need the Muxes and Transceivers (no DCU, no EDFA)
Pluggable Transceiver options (check with your Switch / Router supplier to see what they support)
So, no matter if you want to use 100G LR4 or 100G DWDM pluggable transceivers, options exist to easily and cost effectively expand your Metro network.
