The useful distinction
Understand the requirement.
LC PC duplex · OM4 · two fibers; factory polarity not established for the selected zipcord option. [C337A]
The selected Corning Jumper in a Box reference belongs to the two-fiber patch-cord family. Its ordering section requires separate choices for cable/fiber, length and packaging; it does not identify one measured or purchased cord. [C337B]

Before you connect
What to check
Match the exact manufacturer series and selected variant.
Check each endpoint and its mating polish independently.
Resolve fiber category, organization and any required Tx/Rx map.
Check exact equipment, wavelength, loss budget and safe handling separately.
