In this talk three opportunities for PLC chips will be addressed in 5G mobile networks, fronthaul and backhaul, and datacenter transceivers. Firstly we will discuss low loss and small footprint AWG for 400Gb/s and 800 GB/s CWDM4 and LR8 transceiver for datacenters. Secondly we show the latest progress on cyclic AAWG for outdoor operation that will support ITU-T and IEEE WDM-PON standards like NGPON, metro 698.3 and 698.4 as well as Super-PON which could become important in 5G networks especially if tunable laser become commercially available at low cost. Thirdly it is considered what the implications are of the emergence of coherent modulation on the DWMD network. AAWGs will be shown with wider bandwidth to support the latest coherent standards like 400G ZR for DWDM.
Henk Bulthuis is director of the R&D group of Broadex Technologies UK, formerly Kaiam Europe, Gemfire Europe, Avanex, Alcatel Optronics and Kymata. He co-founded BBV software BV and BBV design BV which were acquired by Kymata in 2000. Close to 800 mask reticles and 2000 of his PLC/PIC designs were simulated, layed out fabricated and tested. Most of the designs were made in glass or silicon technologies.
