Further technical scheme is also to comprise network management responder; Described network management responder is fixed on outer casing upper cover and is electrically connected to keyset.
Preferably, keyset is provided with the electrical connection slot, and the link of network management responder is plugged in this electrical connection slot.
Further technical scheme is, described power supply module is arranged on an end of outer casing upper cover, and keyset is located at another end of outer casing upper cover.Effectively improve the thermal balance performance of upper cover and lower cover, even upper and lower covers does not have that in the situation of fastening, equipment also can move reliably from heat radiation, greatly improve complete machine thermal design performance, also effectively reduce the thickness of complete machine simultaneously, reduce manufacturing cost.
Further technical scheme is that light signal transmitter module assembly, optical signal receiving module assembly are fixedly mounted on outer casing upper cover by screw respectively.
Further technical scheme is, the quantity of described light signal transmitter module building-blocks assembly is two; Two light signal transmitter module assemblies select circuit to be electrically connected to keyset by one.When such structure is damaged one of them light signal transmitter module assembly, can first make another light signal transmitter module assembly work by the selection circuit, then change the assembly that damages, make the impact that the user is caused due to maintenance reduce.
Further technical scheme is that the quantity of described optical signal receiving module assembly is two; Two optical signal receiving module assemblies select circuit to be electrically connected to keyset by another.When such structure is damaged one of them optical signal receiving module assembly, can first make another optical signal receiving module assembly work by the selection circuit, then change the assembly that damages, make the impact that the user is caused due to maintenance reduce.
When the built-in function assembly connecting structure of optical receiver of the present utility model has reduced maintenance, the probability of the online equipment of integral demounting, reduced complete machine spare part amount, improved the maintenance of online equipment and replacing, the handling speed of assembly; Realize parallel model production, the Task of Debugging of tissue take functional unit as unit, enhance productivity, also improve the complete machine thermal design simultaneously, improved the operation efficiency of reliability and general purpose module.
