High-Speed Train Cell-less Network Enabled by XGS-PON and Impacts on vRAN Split Interface Transmission

We successfully demonstrate a transmission of a high layer split mobile interface for cell-less, high-speed train network applications using a commercially available XGS-PON. Operation is also demonstrated for a GbE interface

System aspects of the FDMA PON conceived within the FABULOUS European project (Invited)

Real-Time DSP-Free 100Gbit/s/λ PAM-4 Fiber Access Link using EML and Direct Detection

A 100 Gbit/s/ λ PAM-4 fiber link with an optical budget of 30 dB and 20 km fiber reach is achieved in real time experiments. This is compliant with class A (20 dB) point to point (PtP) applications as mobile fronthaul for example, and with class N1 (29 dB) point to multipoint (PtMP) for residential market. We used an integrated externally modulated laser, an analog pre-equalizer, an optical booster amplifier and/or non-filtered preamplifier and direct detection without any digital signal processing (whether real-time or offline)

Double external cavity laser diode for DWDM applications

International audienceA balanced dual-wavelength external cavity laser diode operating at 1.3 µm is reported with a side-mode suppression ratio of >35 dB. The construction of this laser is based on a double external cavity using a 1:2 coupler and two different Bragg reflectors photo-written within each channel. Thanks to the photo-written external cavity behaviour, a laser with more than eight channels could be considered
