Selection Notes
- Typically selected when OTDR work needs a repeatable reference/launch module to measure the first and last connector events more consistently, especially when teams want to standardize testing across different sites.
- May not be appropriate for organizations that cannot keep connector polish type (PC/UPC/APC), interface family, and launch length consistent across projects, since mixed configurations commonly reduce comparability and increase retesting or acceptance disputes.
Application Details
- Telecommunication Networks: For accurate OTDR testing in long-distance fiber optic installations.
- FTTH Projects: Ideal for insertion loss measurement in fiber-to-the-home setups.
- Field Testing and Troubleshooting: Rugged design ensures reliable performance even in outdoor and harsh conditions.
- Laboratory Calibration: Use in controlled environments for connector reflectance and loss measurements.
