Source context

Recorded scope and limits

Manufacturer comparison dated October 8, 2024. Establishes the two fiber increments as counts on a 24-fiber trunk: base-8 is three MPO connectors of eight fibers each, base-12 is two connectors of twelve, and base-8 uses every fiber in the connector so that one system serves both duplex and parallel optics. It does not state how many duplex ports a cassette presents in either system; the guide derives that by division and says so. Checked September 16, 2026.
