Sunet POC - first day testing. - Sunetc-teknik

      Hi Michal

The tester are seeing burst of error on the 10tce 10G interfaces. the routers shows them
as well.

I stoped the test sending traffic on all three types of interfaces and are now only
sending 10x10Gbps.

I cleared the counters of the router and this is after the first burst of errors.

the other 9 shows the same.

Also see CRC on the 10TCE card, but just a few

So something is a bit odd.

  Hello Magnus, Bjoern,

 I would like to make short summary:

 -          full system is up and running: Juniper Cordoba interface as external channel,
100G LR4 interface
 over 1310nm and 10TCE100G with coherent CFP.

 -          T9 test: Load balanced traffic over all links is running. We will capture
results tomorrow.

 -          setup was adjusted to resemble field environment: EDFA was removed from Uni-1
to make it fully
 passive, fiber spool was used between Stam-2 and Uni-2.

 -          it was agreed that on the core network we will keep possibility to have 96
channels due to that
 ROADM setpoints were adjusted to -20dBm and power per channel coming out of EDFA to 0dBm

 -          ROADMs which face drop sites (Uni-x) will have no more than 8 channels. Power
per channel was
 increased to 6dBm in order to compensate for insertion loss and fiber loss

 -          receiver sensitivity tests were performed results will be put on Visio diagram
prepared by Bjoern.
 Attenuation was increased:

 o   Uni-1 > Stam-1 (link loss 7dB + 2dB from filters): LR4 was working properly with
additional 7.5 dB,
 Cordoba and 10TCE with 11.5dB and ER4 up to 17dB

 o   Stam-1 > Uni-1 (link loss 7dB + 2dB from filters): Cordoba and 10TCE with 13dB

 o   Stam-2 > Uni-2 (link loss 15dB): Cordoba and 10TCE worked with additional 13.5dB

 o   Uni-2 > Stam-2 (link loss 15dB): Cordoba and 10TCE worked with additional 10.5dB
