Type B Fiber Mapping and Female MPO Connections
This type b om4 mpo cable uses reversed fiber-position mapping: position 1 connects to position 12, position 2 to position 11, and so on.
Both MPO/PC connectors are female, with guide holes and no guide pins. Confirm that the mating interfaces have the correct pin configuration before connection.
When routing this 12 fiber om4 mpo cable through panels or cassettes, check the complete channel mapping to ensure the transmit and receive paths align correctly.

Applications
This om4 mpo patch cable is intended for installations that specify OM4 multimode fiber and compatible MPO connectivity:
- Rack-level patching in OM4 data center networks
- Connections between compatible MPO distribution panels
- Links to MPO cassettes with matching pin configuration and polarity
- Plenum cabling routes requiring an OFNP-rated assembly
For parallel-optics applications, select this 12 fiber om4 mpo cable only after checking the transceiver interface and channel design. Confirm that the connector gender and reversed mapping of this type b om4 mpo cable match the link requirements; operating distance must follow the selected optics’ OM4 specifications.

End detectionQ1: What should determine the length of this om4 mpo patch cable?
Choose the length to suit the actual routing path, including cable management and service slack. Check the complete channel length against the OM4 distance supported by the selected transceivers.
Q2: Can this 12 fiber om4 mpo cable connect to any MPO cassette?
No. The cassette must match the cable’s female MPO/PC connectors, 12-fiber configuration and polarity requirements. An MPO port alone does not confirm compatibility.
Q3: Is this type b om4 mpo cable interchangeable with a Type A cable?
Not without checking the channel design. Type A and Type B use different fiber-position mappings, so substitution can change the transmit-to-receive paths.
Q4: What does the OFNP designation refer to?
OFNP identifies the cable’s plenum fire rating, rather than its optical performance. Confirm that the supplied assembly’s jacket marking and supporting documentation meet the project requirements.
