Optical Fiber Time Delay Comparison Between NIST and LAMETRO
Summary
A measurement comparison of optical fiber time delay between NIST and LAMETRO-ICE showed results within expected uncertainty. This validates precise optical fiber metrology between international laboratories.
Area of Science:
- Metrology
- Optical Engineering
- Telecommunications
Background:
- Accurate measurement of optical fiber time delay is crucial for high-speed data transmission.
- International collaboration enhances the reliability and comparability of metrological standards.
Purpose of the Study:
- To conduct a bilateral measurement comparison of optical fiber time delay.
- To validate the measurement capabilities of NIST (USA) and LAMETRO-ICE (Costa Rica).
Main Methods:
- Utilized a single-mode optical fiber reference spool.
- Performed measurements at standard telecommunication wavelengths: 1310 nm and 1550 nm.
- Compared time delay results between the two participating laboratories.
Main Results:
- The largest difference in measured time delay was less than 0.93 ns.
- This difference was within the combined standard uncertainty (k=1) of the measurement systems.
- Demonstrated agreement between NIST and LAMETRO-ICE measurement systems.
Conclusions:
- The bilateral measurement comparison successfully validated the accuracy of optical fiber time delay measurements.
- Results confirm the equivalence of metrological capabilities between NIST and LAMETRO-ICE.
- The study supports international confidence in optical fiber metrology standards.
