Endpoint map

Start with what is physically represented

Equipment direction and end-to-end Tx/Rx mapping are not resolved by a passive optical reference or by selecting its connector ends. Read the separate polarity field.

More than the connector ends

Corning Jumper in a Box — LC PC 0505 / ZR4 OM4 option

End A polish documented

LC PC, using the page 6 connector-code wording.

C337A

End B polish documented

LC PC at the second duplex end; not silently renamed UPC.

C337A

Fiber category documented

OM4

ZR4 is the named OM4 option, not a conclusion from LC shape.

C337A

Organization documented

duplex

LC duplex option within the two-fiber family.

C337A · C337B

Fiber count documented

Two fibers; a paired organization rather than a protocol promise.

C337B

Polarity / path mapping not established

Not established

The selected page 6 zipcord option does not establish a factory A–A/A–B map. Do not borrow the separate uniboot page’s mapping.

Polarity change not established

Not established

Polarity-changeability for this selected zipcord option is not established.

Coupling / sleeve not applicable

Not applicable

This is a cord assembly, not a separate coupling-adapter sleeve selection.

No compatibility verdict. Different polishes at separate ends of a documented cord do not permit direct mating of unlike physical-contact polishes at one joint. Never look into a live fiber or port.

Capability ledger

Six questions kept separate

DataConditional

No protocol, data rate, wavelength or complete link budget is assigned. Resolve exact transceivers and the entire optical path.

Evidence: C337A

Power / chargingNot Applicable

No electrical power-delivery role is represented.

VideoNot Applicable

No TOSLINK, HDMI or other video/audio protocol is inferred from network-fiber endpoints.

ConversionNone

No active signal or media conversion is represented. Connector adaptation is not a mode or protocol conversion.

Evidence: C337A

Length / reachProduct Specific

The order pattern leaves length unselected. Cable length is not an approved optical reach.

Evidence: C337A

Markings / certificationProduct Specific

Read the exact named series and selected variant. Connector color is not a substitute for endpoint-polish and fiber documentation.

Evidence: C337A

Explicit unknowns

Exact selected item, current condition, optical-port support and installation remain unverified.
No wavelength, protocol, link budget, end-to-end speed or hardware result is determined.
No direct mating of unlike physical-contact polishes is recommended; differing ends of a documented cord are distinct mating joints.

Common questions

Questions this record can help resolve

How do I read a fiber patch-cable label?Separate connector ends, each end’s polish, fiber category, fiber count and path mapping before checking the equipment.Does a reversible LC uniboot prove the polarity of my link?Keep a named cable’s factory mapping, its change mechanism and the actual end-to-end duplex path separate.
