This document summarizes a field trial of 100G DP-QPSK multi-vendor interoperability over 1030 km. Juniper and Cisco routers were able to successfully transmit and receive 100G coherent signals over the Telxius network, demonstrating interoperability between the vendors. A 3.2 dB margin was measured after 1030 km. Telxius plans to use this solution in backhaul networks and explore using it in submarine links. They desire this level of interoperability with their DWDM providers.

• We demonstrated 100G coherent DWDM multi-vendor line-side
interoperability between Juniper MX2020 and Cisco ASR9904 routers over
a 1030-km DWDM link in the Telefonica network. The DWDM line cards
use 100G CFP2-ACO pluggable coherent DWDM optics and supports the
HG-FEC line-side interworking code. A 3.2 dB margin is measured after
1030 km for the multi-vendor line-side interoperability tests, whereas
single-vendor measurements using a proprietary SD-FEC code showed a
4.0 dB system margin.
• We are planning to put this solutions in our backhauls.
• We will continue looking for the possibility to use this solution in some
submarine links.
• We will desire to have this type of solution with our DWDM providers.
