A time synchronization method and a time synchronization device in a passive optical network (PON), and a PON are provided. The method includes receiving a synchronization packet sent after time synchronization of an optical line terminal (OLT) with a master clock (MC) is achieved, wherein the synchronization packet carries a timestamp TMt1i determined after the time synchronization of the OLT is achieved, adjusting a local clock according to the timestamp to achieve time synchronization of an optical network unit/optical network terminal (ONU/ONT) with the OLT, and after the time synchronization of the OLT is achieved, instructing an slave clock (SC) to perform time synchronization. A time synchronization device and a time synchronization system for implementing the method in a PON are further provided.
Abstract:
A heat dissipation device is provided in the present disclosure, where the heat dissipation device includes a hollow heat-sink base and a set of fluid tube. The fluid tube is inserted in the heat-sink base, and a cooling medium circulates in the fluid tube. The heat-sink base includes a heat absorption area configured to absorb heat.

Abstract:
The present invention discloses a method, device and system for managing information of an optical node in an optical distribution network, relates to management of information of an optical node in an optical distribution network, is capable of solving the problem of manual entry of information of an optical node being cumbersome, and is not limited by installation locations of the optical node. The method for managing information of an optical node in an optical distribution network includes: obtaining an identity code of an optical node; querying a pre-established optical node information table according to the identity code of the optical node, wherein the optical node information table comprises the identity code of the optical node and the installation location information of the optical node. The present invention is suitable for management of information of an optical node in an optical distribution network.
Abstract:
Embodiments of the present disclosure disclose an optical cable and an optical cable system, where the optical cable includes an SZ-shaped optical cable skeleton and a plurality of optical fiber units. Skeleton slots is recessed in a periphery of the optical cable skeleton, and the plurality of optical fiber units is grouped and respectively disposed in the corresponding skeleton slots, thereby having the advantages of being easy to strip and draw, high reliability, and long lifetime. Moreover, the optical fiber does not need to be connected when being diverged on floors during installation, thereby reducing the fusion splicing/termination connection time, simplifying the optical cable wiring, greatly reducing deployment cost of an Optical Distribution Network (ODN), and speeding up the scale deployment of the FTTX ODN; in addition, interference among the optical fibers is avoided when the optical fibers are drawn, thereby increasing reliability of the optical fibers after installation.
Abstract:
A method for load balancing based on Transparent Interconnection of Lots of Links (TRILL) is provided. Said method comprises: acquiring, by a routing bridge (RB), all current medium access control (MAC) addresses within each virtual local area network (VLAN) on a link where the RB is located. And if said RB is selected as a designated routing bridge (DRB), said RB distributes all the current MAC addresses acquired within each VLAN between said RB and other RBs on the same link according to a preset distribution rule, and notifies said other RBs to be responsible for forwarding of messages having a specified MAC address and VLAN, wherein said MAC addresses are the MAC addresses of the host devices on the link where said RB is located. If said RB is a common RB, said RB receives a notification sent by a DRB and learns that it is responsible for forwarding of messages having a MAC address and VLAN specified in said notification; and upon receiving a message sent by a host device, said RB determines whether said message is a message it is responsible for forwarding according to the VLAN and the MAC address of the host device carried by the message; if yes, said RB forwards said message; and if no, said RB discards said message.
Abstract:
A pluggable mechanism, disposed between a bearing board and a to-be-inserted board, includes: a gear wrench hinged on the bearing board, where the gear wrench comprises a handle and a drive tooth part; and a swing gear, hinged on the bearing board and connected to the to-be-inserted board, where the swing gear comprises a gearing tooth part meshing with the drive tooth part, and the to-be-inserted board moves with the move of the swing gear. A production board including the above pluggable mechanism is also disclosed. A subrack including the above production board is also disclosed. The pluggable mechanism has a simple structure, high reliability, good operability, no occupation of vertical space, and small motion resistance, and is suitable for board plugging requiring great force for inserting and removing.
Abstract:
An optical switch includes: a semiconductor substrate, including a first rotation part and a first torsion beam disposed at two ends of the first rotation part, where the first torsion beam is configured to drive the first rotation part to rotate; a microreflector, disposed on a surface of the first rotation part of the semiconductor substrate; a first latching structure, disposed on a surface of the first torsion beam, the first latching structure including a form self remolding (FSR) material layer and a thermal field source, where the thermal field source is configured to provide a thermal field for the FSR material layer and the FSR material layer is configured to undergo form remolding under the thermal field, so as to latch the first rotation part and the microreflector in a position after rotation.
Abstract:
The present invention relates to a health massage apparatus, providing a neck massager including a U-shaped neck pillow capable of being hungon a neck of a person, an inside of the U-shaped neck pillow corresponding to the neck has at least one massage component, the at least one massage component include at least two massage heads from the top down along the inside of the U-shaped neck pillow, a height of the upper massage head is lower than the adjacent lower massage head in sequence. According to the human neck characteristics involving the protrusion of the upper neck and the depression of the lower neck, in the present invention the upper massage head is set a low position and the lower massage head is set at a high position, advantageously, each of the massage heads respectively massages the corresponding neck part, the good massage effect can be obtained.
Abstract:
Computing devices can autoconnect to access points even if they have not previously received authentication information for those access points. A computing device broadcasts a probe request, comprising a request for authentication information. An access point receiving such a probe request generates a probe response that provides authentication information that the computing device can then utilize to establish a useful communication connection to the access point. The provided authentication information can be either encrypted or unencrypted, and can be encrypted for specific users or specific computing devices. Dedicated application programs can decrypt encrypted authentication information, thereby enabling autoconnecting, while also delivering targeted information to users of the autoconnecting computing devices from a retailer hosting the access point. Authentication information for a “landing page” can be provided to a web browser to enable autoconnection.
