Abstract: An optic fiber adaptor includes two flexible engaging members and two positioning walls cooperating with one another to define an insertion slot. Each engaging member has a first inclined surface and a second inclined surface disposed behind the first inclined surface. A distance between the first inclined surfaces of the engaging members decreases rearwardly so as to facilitate pushing of a casing body of a ferrule assembly into the insertion slot. A distance between the second inclined surfaces of the engaging members decreases forwardly so as to facilitate pulling of the casing body out of the insertion slot. An optic fiber connecting device having the optic fiber adaptor is also disclosed.

Abstract: An optical fiber coupling device includes a casing and a coupling component. The casing has a receiving slot that extends therethrough along a first direction. The coupling component is removably disposed in the receiving slot of the casing, and has at least one coupling slot that extends therethrough along the first direction. The at least one coupling slot has two opposite plugging sections that are arranged along the first direction. The plugging sections are compatible with one of LC, MPO and SC connectors.

Abstract: An optical fiber connector includes an outer sleeve and a main casing body. The outer sleeve includes a surrounding wall and a key portion extending forwardly from the surrounding wall. The main casing body includes a wall portion defining a mounting space for receiving a portion of a mechanical transfer (MT) ferrule mounted with a plurality of optical fibers therein. The outer sleeve is detachably sleeved on the wall portion. The wall portion has two opposite outer connecting surfaces formed respectively with two keyways. The key portion engage one of the keyways. The outer sleeve is detachable from the main casing body so as to allow the key portion to engage the other one of the keyways.

Abstract: An optical fiber connector device includes an optical fiber connector that includes an LC connector head and an optical fiber cable connected together along an axis, and an insert unit that includes a housing entirely molded as one piece. The housing has an outer wall which defines a main opening, and a surrounding wall which defines an insert opening. The main opening and the insert opening are open respectively towards opposite directions along the axis. The connecting subunit includes a first connecting member inserted into the main opening, and connected to the LC connector head, and a second connecting member coupled to the first connecting member, and adapted to be connected to another optical fiber connector.

Abstract: Provided is a method of producing poly(vinyl butyral) laminate from discarded laminated glass. By means of breaking the discarded laminated glass, water-washing and grinding the reduced glass fragments, a reusable poly(vinyl butyral) material substantially free of glass pieces is obtained by physical treatment without using any organic solvent. After drying, granulation and formation steps, a poly(vinyl butyral) laminate is further obtained from the poly(vinyl butyral) material. Accordingly, the method not only reduces resource waste but also produces a water-proof poly(vinyl butyral) laminate, and is more environmentally friendly and more applicable to industry.

Abstract: In a near-field communication (NFC) service protection method of the mobile device, the mobile device includes an NFC controller, one or more security elements, a global positioning system (GPS) and a storage system. The method sets a security code for an NFC service of each of the security elements according to the geographic location of the mobile device as acquired by the GPS, and stores a security protection of the NFC service corresponding to each of the NFC services into the storage system. After an NFC service is selected from one of the security elements, and the NFC service is performed by executing an NFC application corresponding to the NFC service through the NFC controller. In addition, the method deletes the security code of the NFC service to disable the security protection of the NFC service when the NFC service needs to disable the security protection.
