When to Use a PMF Patch Cord / Pigtail
- External laser source to FAU feed in CPO switch trays
- Polarization-sensitive silicon photonics test and measurement
- Coherent-system reference leads
- Optical sensor and lidar polarization-preserving links
- NPO and CPO prototypes
Use a PMF FAU instead when
The connection terminates directly on a photonic chip or optical engine that requires a multi-fiber array with fixed pitch and slow-axis alignment.
Use a standard single-mode patch cord instead when
The optical path is not polarization-sensitive and does not require a maintained polarization state.
Installation and Acceptance Checklist
- Confirm slow-axis orientation relative to the connector key.
- Specify connector type, polish and gender where applicable.
- Define jacket rating against facility and local-code requirements.
- Agree on insertion loss, return loss and extinction-ratio limits.
- Verify length, labeling and packaging before production.
- Observe the specified bend radius and tensile load during installation.
