AI Article Synopsis
- Direct detection systems, particularly using PAM-4 modulation, are crucial for cost-effective and low-power metropolitan networks, but face challenges with transmission distance in the C-band.
- Utilizing a dual drive Mach-Zehnder modulator allowed for the creation of a chromatic dispersion (CD) pre-compensated signal, achieving successful 128 Gbit/s transmission over an 80 km SSMF link.
- This method represents the longest reach reported for single lane 100 Gbit/s PAM-4 signals in DCF-free links, enhanced by synchronized bandwidth pre-compensation to address bandwidth limitations.
Article Abstract
Direct detection systems with advanced modulation schemes are of great importance in metropolitan networks, because of their low cost and low power requirements. In particular, PAM-4 has attracted considerable attention, but has significant transmission distance limitations in the C-band. To extend its reach, we used a dual drive Mach-Zehnder modulator to generate a chromatic dispersion (CD) pre-compensated signal with an extra (j-1) multiplication to align the optical carrier and the modulated optical signal; by doing so, we achieved successful 128 Gbit/s transmission over an 80 km SSMF link, the longest reported reach of single lane 100 Gbit/s PAM-4 signals over DCF-free links. Synchronized bandwidth pre-compensation was also used, to reduce the influence of bandwidth-limitations.

About 50% of all cancers carry a mutation in p53 that impairs its tumor suppressor function. The p53 missense mutation p53 (p53 in mice) is a hotspot mutation in various cancer types. Therefore, monoclonal antibodies selectively targeting clinically relevant mutations like p53 could prove immensely value.

Osteoarthritis of the wrist presents complex surgical challenges. A wide variety of surgical options are available when conservative management fails to provide adequate pain relief. Despite advancements in management, such as modifications of partial wrist arthrodesis techniques and increasing use of total wrist replacements, in most scenarios there is no single preferred option.
