- Abstract
- We experimentally demonstrate 100 Gb/s bidirectional transmission over 40 km using a multi-wavelength bidirectional optical sub-assembly (BOSA) based on a single bidirectional multi-wavelength Mux/Demux. The Mux/Demux consists of an optical zig-zag glass block and thin film filters. Four wavelengths with 800 GHz spacing (that is, two wavelengths for each direction) within a 20-nm band in the O-band are utilized, and there is no four-wave mixing penalty. The multi-wavelength BOSA enables the bidirectional transmission of 2 × 50 Gb/s PAM4 signals over a 40-km single-fiber link. The multi-wavelength BOSA with multi-level modulation presents a suitable approach for future speed and transmission distance increases in 6G networks and data-center interconnections.
