  • Is there a risk of data leakage with optical modules

    Is there a risk of data leakage with optical modules

    The major risk is the possibility of inserting a splitter into the optical distribution network and capturing a portion of the entire spectrum, i., all channels in the optical fiber. According to the Thales Data Threat Report 2020 by IDC, nearly half of surveyed global organizations have experienced a data security breach at some point, and 26% were breached in 2019.
