摘要： An adapter for an optical fiber connector has a switch mounted therein and an actuation lever contained therein for actuating the switch to turn optical power on. The lever has an enlarged rear portion separated from a front portion by a flexible web. The adapter has an opening therein for receiving a connector plug which is masked by the enlarged portion of the lever when in the operative position. When a plug is to be inserted, the enlarged portion is bent up to unmask the opening. After the plug is inserted, the rear portion is aligned with the front portion of the lever and the lever slid forward to actuate the switch. In the forward position, the enlarged portion prevents access to the latching arm of the connector plug so that it cannot be removed while the power is on. The lever must be slid to the rear, turning off the power, before the connector can be removed. Latches maintain the lever in its forward, or Power On position, which can be overcome to permit sliding the lever to the rear, or Power Off position, before access to the connector plug latching arm can be had.
摘要翻译： 用于光纤连接器的适配器具有安装在其中的开关，并且容纳在其中的致动杆用于致动开关以打开光功率。 杠杆具有通过柔性腹板与前部分开的扩大后部。 适配器在其中具有用于接收连接器插头的开口，当处于操作位置时，连接器插头被杠杆的扩大部分所掩蔽。 当插入插头时，放大部分向上弯曲以揭开开口。 在插头插入后，后部与杆的前部对准，并且杆向前滑动以致动开关。 在向前位置，放大部分防止连接器插头的锁定臂的进入，使得在电源接通时不能被去除。 在拆卸连接器之前，必须将杠杆滑到后面，关掉电源。 闩锁将杠杆保持在其向前或开机位置，可以克服，以允许将杆滑动到后部或关闭位置，然后才能进入连接器插头闩锁臂。

摘要： An attenuator element for use within an optical fiber adapter is disclosed. The attenuator element has an elongate block-like head, the head having tapered side walls and beveled surfaces extending along a portion of the respective side walls and a lower planar surface thereof, a neck extending from the lower surface thereof, and an attenutaor disk extending from the neck. The attenuator element is constructed and arranged so that it may be inclined through an angle of from 90° to 82° with respect to the longitudinal axis of an alignment sleeve used to couple two optical fiber connectors together in order to accommodate the coupling of optical fiber ferrules having end faces which are aligned with one another along the longitudinal axis of the alignment sleeve, or where the ferrule end faces may be angled with respect to the longitudinal axis of the alignment sleeve. The attenuator element is also constructed and arranged so that it may also be selectively rotated about a longitudinal axis of the attenuator disk and between the end faces of the opposed ferrules received within the alignment sleeve.

摘要： A dust cover for protecting a sleeve housing of a fiber optic adapter having opposed interior sidewalls is provided, which includes an elongate member having first and second opposed ends wherein the elongate member has a multifaceted outer surface with at least one planar surface for engaging the opposed interior sidewalls of the fiber optic adapter. The first end of the elongate member is sized and shaped to align the elongate member within the fiber optic adapter and receive the sleeve housing. The first end of the elongate member also includes a longitudinally extending central bore for receiving the sleeve housing and a plurality of landings, which are contiguous the longitudinally extending bore, and which are tapered toward the second end. The landings securely hold the sleeve housing within the central bore of the elongate member. With this arrangement, the dust cover prevents contamination to the optical fiber, is self-aligning, is accessible in panels having deep recesses, and is easily removable from fiber optic adapters, thereby overcoming limitations found in conventional dust covers.
