Millimeter wave link with a data transmission rate of 40Gbps

[ankarb]

I saw recently the following:

https://www.telecompaper.com/news/deutsche-telekom-e*******-achieve-40-gbps-in-e-band-backhaul-trial--1275915

But from what I know E// has MINI-LINK 6352 which supports 10 Gbps over 2000 MHz channel.

Do you know how they achieved 40Gbps over a hop distance of 1.4 km?!!! :confused:

Thanks.

due to distance and climatic zone ..I think they are talking about D Band link 64/128QAM - >10GHz bandwidth

I verified ...
They use
2xMINILINK Eband in XPIC with channel of 2Ghz and 128QAM modulation
per terminal (so 2GHz Hpol 2GHz Vpol XPIC) ->20gbps
then they duplicate the configuration with inner router 6675
so
the innovation part is the inner router able to LAG 4x10GBE ports

anything revolutionary as first time they wanted to show
