The disclosure provides a vibrating wire compressive stress gauge and stress testing equipment suitable for use in low-temperature environments. By providing a stress trigger sleeve made of elastic material, the concrete structure of the lining itself expands when it is affected by high or low temperatures, extruding the stress trigger sleeve, and the extrusion force is offset through the elastic force of the elastic material, thereby preventing the expansion force from being transmitted to the vibrating wire assembly to generate stress signals that are caused by the self-expansion of the lining structure, which may cause measurement error. Specifically, the vibrating wire assembly is provided in the vibrating wire measurement space composed of a stress trigger sleeve and a pair of anchoring disks. When the lining is subjected to external stress, a certain internal force will be generated.

Embodiments of the present disclosure disclose a method and an apparatus for restoring a NETCONF server to factory defaults, and relate to the field of configuration management technologies. A NETCONF server receives a command for restoring to factory defaults sent by a NETCONF client, where the command for restoring to factory defaults is a remote procedure call (RPC) command that is based on a Yang model of the NETCONF for restoring the NETCONF server to the factory defaults. The NETCONF server replaces data in the running configuration datastore with factory defaults of the NETCONF server according to the command for restoring to factory defaults.

Method and apparatus for restoring network device to factory defaults, and network device

Embodiments of the present disclosure disclose a method and an apparatus for restoring a network device to factory defaults, and a network device, and relate to the field of configuration management technologies. A NETCONF server determines that the network device needs to be restored to the factory defaults; the NETCONF server replaces data in a startup configuration datastore and a running configuration datastore in the NETCONF server with factory defaults data in a factory defaults datastore, where the factory defaults datastore is dedicated to storing the factory defaults data of the network device. The NETCONF server delivers the data in the running configuration datastore after replacement to a plurality of service modules. Then, the plurality of service modules performs a validation operation based on the data delivered by the NETCONF server.

Disclosed are an optical module unlocking device and an optical module. For the optical module unlocking device, a boss is arranged on a metal front end of a pull ring. The boss abuts against the skewed slot of an upper cover. The metal front end located in the upper cover can slide relatively along the limiting post of the upper cover and at least one boss is driven to slide into the skewed slot of the upper cover and then hide into the bottom of the skewed slot or abut against a bevel edge of the at least one skewed slot and then bulge. After the at least one boss abuts against the bevel edge of the at least one skewed slot and then bulges, a shielding cage spring strip which is about to be cooperated with the boss is opened by being pushed upwards, and the optical module can be unlocked. The reliability of the optical module unlocking device is high and the unlocking motion of the optical module is simple. The optical module unlocking device of the present disclosure has the advantages of less component quantities, simple assembling, high assembling efficiency and low cost.

An electric-port SFP photoelectric module includes a base, an outer cover, a PCB and an RJ45 connector. The base is a rectangular parallelepiped with an inner cavity. The PCB and the RJ45 connector are connected in a combined manner. A combined structure of the PCB and the RJ45 connector is arranged in the inner cavity of the base. The upper part of the base is fastened with the outer cover.
