“…Connectors and adaptors are very needed to perform the optical network operation. Some researchers have done experiments about connector (Suzuki et al, 1986;Satake et al, 1986;Nagasawa et al, 1991;Iwano et al, 1992;Young et al, 1989;Parzygnat, 1987;Sankawa et al, 1986). There are four typical contact type of connectors.…”

Problem statement:The reliability of the entire communications network was dependent on the reliability of each single element. Connector was important devices that can affect the performance of the fiber communication. There were a large number of issues that affect the performance of fiber optic connectors in today's networks. These factors were increasingly as data rates, the number of wavelengths and transmission distances continue to escalate. Approach: Therefore this study was carried out to test on the influence of connectors and adapters to the performance of the optical network. Initially the actual attenuation of connector and adaptor were tested by using multifunction loss tester. The first two 1 m corning optical fibers with a connector at each end are measured. Then, both the 1 m corning optical fibers were joined together by an adaptor and connected to the Multifunction loss tester. Three types of wavelength are used as the source to test the attenuation of the fiber which is 1310, 1490-1550 nm. In order to measure the Bit Error Rate (BER) and the power loss in optical fiber communication, a simple simulation was carried out by using software opti sys. Results: The attenuation on the connector was caused mainly by existence of impurities in the connector, less perfect connection, scattering of beam and others. These causes the parameter such as power received, Q-factor, minimum BER and also the eye-height to change. Changes in these parameters also affect the performance at the user end. It was very critical that causes of attenuation to be eliminated. Conclusion/Recommendations: From the result it can be concluded that, the greater the attenuation, the greater the decrease in power received. It also affects the Q-factor of the system where as the attenuation increase, the maximum Q-factor decreases. As for the minimum BER, minimum BER changes as the attenuation increase initially, after a maximum value it decreases as the attenuation increases.

“…They are perpendicular and oblique endface connectors employing either physical contact or contact via index matching material. The oblique endface connector is very effecti to reduce the reflection (Suzuki et al, 1986;Nagasawa et al, 1991;Young et al, 1989). The physical contact type connector has also been analysis to improve the return loss.…”

The core diameter of a single-mode fiber is about 8 to 10m. Any slight misalignment or deformation of the optical mechanism will cause significant optical losses at connections. Previous studies have concentrated on improving the manufacturing process to obtain highprecision components. Although the precision can be controlled, misalignment may still occur owing to the contact stress on the connecting interface. This study used the finite-element method to simulate the contact status, and used MT-series connectors as examples. The connectors use a guide-pin structure to align the two contact surfaces, and use a spring or clip to maintain tight contact. Because the MT ferrules are made of plastic materials, they are softer than ceramic ones and the deformation strains are more significant. For the finite-element analysis, a solid model of the MT ferrule with a convex end, oblique angle, and fiber protrusion can be constructed according to the JIS C5981 standard. Results of a simulation, integrating the optimization technique and AN-SYS software, showed that the fiber center displacement for the commonly used oblique PC connectors would be 0.9 m. This will significantly affect the eccentricity tolerances for single-mode applications, because a maximum of 1.5 m is acceptable. Using the resulting new standard ͑eccentricity Ͻ0.6 m͒ to select ferrules, and making them into connectors, it is found that the insertion losses in 98% of connectors are less than 0.3 dB. This result satisfies the requirement for single-mode applications.
