Stefan Voll, VP Product Management, Infinera – “Pushing Coherent Optics to the Edge”

Coherent C-band transport technology in a mobile context has been limited to backhaul scenarios. 5G and future 6G push bandwidth needs at radio units higher so that network architectures need to move beyond 25G connections. In this networking segment, coherent technologies so far could not prove in. Stefan will discuss how a new breed of subcarrier-based optical aggregation pluggable transceivers is able to change the game.

Antonio Tartaglia and Fabio Cavaliere from Ericsson – “Optimized optical solutions for mobile networks: the battle of the bands”

Mobile transport is a unique segment, conjugating the extreme cost sensitivity of access and some performance requirements typical of metro transport. Up to 25Gb/s per wavelength, we’ve been using the O-band for short reach and fiber abundant scenarios, while we have used the C-band for longer reach and fiber scarce scenarios. Two Ericsson experts exchange their views on the adoption of higher bit rates. Is the rise of 50Gb/s and 100Gb/s going to change the way we use both bands, and how?
