Nice, France here we come! The Acacia team is excited to attend NGON & DCI Europe 2018 this month for the fifth year in a row. There is always something fun to do in Nice, from attending NGON and the annual beach party at le galet to taking in the some of the local architecture designed by Buzzi, Bernasconi, and Baptiste.
We, of course, most look forward to hearing updates from industry luminaries about the future of optical networking and discussing Acacia Communications’ optical interconnect solutions and how they help meet the demands of today and tomorrow’s optical networks. We think some of this year’s hot topics will be:
We look forward to connecting with our peers to discuss these topics. To schedule a meeting with Acacia Communications, please submit a request through our contact form.
You can follow our updates from the show on Twitter @AcaciaComms or #NGON2018.
We look forward to seeing you in Nice!

Figure 1: CFP2 coherent module
Acacia’s engineering team led by Hongbin Zhang recently demonstrated real-time transmission of 16 Tb/s (80x200Gb/s) over 1020km TeraWave ULL fiber with 170km span length using the 200Gb/s CFP2 module. The length, while much longer than typical metro/regional spans, was chosen to stress the OSNR budget while showing achievable amplifier spacing with ultra-low loss fiber. The results showed a record low power consumption less than 0.1W/Gbps. This is the lowest reported power consumption per bit for coherent optical transceivers.
Figure 2: Circulating loop setup for transmission experiments.
For the purpose of this experiment the CFP2 module was implemented in multi-source agreement (MSA) 107.5 mm x 41.5 mm form factor. Test specifics include:
Relying on pluggable CFP2 transceiver modules, we were able to demonstrate successful 200Gb/s real-time transmission of 80 PM-8QAM and PM-16QAM channels at 4 bits/s/Hz spectral efficiency over 1020 km distance using very long 170km spans of TeraWave ULL fiber showing 2.8dB and 1.2dB Q2-margin, respectively. We were also able to prove an increase in system capacity as well as a decrease in power consumption per bit for coherent optical transceivers.
