opticalCON DUO versus QUAD

Does the fiber system specify opticalCON DUO or QUAD, and how many optical channels are documented?

How they differ

  • opticalCON DUO 2-fiber connector system Confirm the DUO family and two-fiber cable system, then verify the optical mode, polish and equipment transceivers separately.
  • opticalCON QUAD 4-channel fiber connector system Confirm the QUAD designation and four-channel construction in the product documentation before choosing cable or chassis parts.

Then askDoes the fiber system specify opticalCON DUO or QUAD, and how many optical channels are documented?
