摘要： The present invention discloses a low-cost high power optical adapter employed to reduce the effects of the contaminants in the high power fiber optical transmission systems. The high power optical adapter uses the exactly same housing of the standard plug style single mode optical attenuators. The attenuating fiber is replaced by a TEC fiber. The TEC fiber has an MFD of more than 25 um at one end and an MFD of about 10 um at the other end that is the same as a standard single mode fiber. In the high power optical adapter, the large MFD end of the TEC fiber is fixed at the male side of the ferrule and the small MFD end of the TEC fiber is fixed at the female side of the ferrule. When the high power optical adapter is employed, the original pair of the standard optical connectors are first disconnected from the standard mating sleeve. Then each of these connectors is mounted into the female sides of a pair of the high power optical adapters. Then the male sides of the pair of the high power optical adapters are connected together through the standard mating sleeve. During the system test, if the high power optical adapters are not needed, then the standard optical connectors can be just dismounted from the high power optical adapters and then reconnected together through the standard mating sleeve.
摘要翻译：本发明公开了一种用于降低高功率光纤传输系统中污染物的影响的低成本大功率光学适配器。高功率光学适配器使用与标准插头式单模光衰减器完全相同的外壳。衰减的纤维由TEC纤维代替。 TEC光纤在一端具有大于25um的MFD，另一端的MFD约为10um，与标准单模光纤相同。在大功率光学适配器中，TEC光纤的大MFD端固定在套圈的外侧，TEC光纤的小MFD端固定在套圈的阴侧。当使用高功率光学适配器时，原始的一对标准光学连接器首先从标准配合套筒断开。然后将这些连接器中的每一个安装到一对高功率光学适配器的阴侧。然后，一对大功率光学适配器的阳侧通过标准配合套筒连接在一起。在系统测试期间，如果不需要高功率光学适配器，则可以从高功率光学适配器中拆下标准光学连接器，然后通过标准配合套管重新连接在一起。

摘要： This invention is related to method for assembling an optical attenuator to attenuate an optical beam. The method includes a step of a) collimating the optical beam from an input optical waveguide into a substantially collimated beam comprising an upper segmented-portion and a lower segmented-portion. The method further includes steps of b) transmitting the collimated onto a phase shifting means comprising at least an upper phase shifting means for generating a phase difference between the upper segmented-portion and the lower segmented-portion and c) generating a self-interference between the upper segmented-portion and the lower segmented-portion of the collimated beam and focusing the collimated beam into an output optical waveguide with an attenuation resulting from the self-interference.

摘要： A first storage unit is bound to a second storage unit based on a binding type associated with content on the first storage unit, the first storage unit being operated through a first host device, and the second storage unit being operated through a second host device. When content on the first storage unit is requested in the first host device, the first host device will calculate an account identifier based on the binding type associated with the requested content and send the account identifier to a server. The server will send the account identifier to the second host device, and the second storage unit will use the account identifier to calculate a credential. The credential will be sent to the first host device through the server. The credential can be used to access the requested content if the credential is valid.

摘要： Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.
