“…[2,4,11] And also we have done the reliability tests and have reported the results of them. [4,5] Further, to verify the validity of the settled parameters, analysis and reliability test by high temperature and high humidity were done for PC contact between different material ferrules of Zirconia (ZrF) and GCF.

“…On the other hand, after high temperature and high humidity test, the permanent fiber withdrawal reached to 0.179µm and the difference of fiber withdrawal between before and after aging test was 0.125µm as shown in Table 2. [4] We have also done water immersion test (45°C, 168hr, 6 cycles) using MU connectors assembled by using Type-N adhesives. In this case, fiber withdrawal change was -58nm in comparison with -80nm in the case using 353ND.…”

This paper will report the development highly moisture durable optical adhesives and the comparison with the currently using optical epoxy adhesive. The median time to failure (MTF) of cured adhesives deterioration was from several times to over 10 times longer MTF (over 3000 hrs) than the currently used one (ca. 300 hrs). Further, these newly developed adhesives were applied to the real optical devices. 253 hr 784 hr 1115 hr UV cure type -1 583 hr 1169 hr KayatoronA-1005S-1 590 hr 530 hr KayatoronA-1002S-2 519 hr 862 hr KayatoronA-1002S-1 170 hr 323 hr 353ND-3 136 hr 235 hr 353ND-2 226 hr 569 hr 353ND-1 90 deg C -85% 80 deg C -85% 784 hr 1115 hr UV cure type -1 583 hr 1169 hr KayatoronA-1005S-1 590 hr 530 hr KayatoronA-1002S-2 519 hr 862 hr KayatoronA-1002S-1 170 hr 323 hr 353ND-3 136 hr 235 hr 353ND-2 226 hr 569 hr 353ND-1 90 deg C -85% 80 deg C -85% 85 deg C-85% 253 hr

Fibre optic connectors are an important factor in the performance of fibre optical systems. In order to ensure good fibre-to-fibre contact, the endface geometry of fibre connectors needs to be measured quantitatively. In this paper, we present a vision-based automatic measurement system for the measurement of the endface geometry of a single-fibre connector. The optical set-up of the system developed is based on a Mirau objective interferometer, and a 3D profile of the connector endface is obtained by using phase-shifting techniques. Image-processing techniques are applied to automatically find the fibre centre and retrieve the geometric parameters of the connector endface, such as radius of curvature, apex offset and protrusion or undercut. Experimental results have demonstrated the feasibility of the proposed system.
