ABSTRACT:
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to fiber converter means and, more particularly, to a fiber converter box, which achieves the work of multiple fiber converters.
Regular personal-computer-to-server fiber optical transmission methods include two types respectively shown in
FIGS. 1 and 2
. According to the method shown in
FIG. 1
, the network interface card
931
of the personal computer
93
is connected to one side of a first fiber converter
919
by a unshielded twisted pair cable
910
, the other side of the first fiber converter
919
is connected to a fiber connector outlet
917
in the wall
92
by a fiber jumper patch cord
918
, which fiber connector outlet
917
is connected to a second fiber converter
916
through another fiber optical cable
902
and then to a switch-hub
914
through another fiber optical cable
915
and then to a router
900
through another fiber optical cable
913
and then to the server
911
through another fiber optical cable
912
. According to the method shown in
FIG. 2
, the network interface card
951
of the personal computer
95
is connected to one side of a first fiber converter
949
by a unshielded twisted pair cable
940
, the other side of the first fiber converter
949
is connected to a fiber connector outlet
947
in the wall
96
by a fiber jumper patch cord
948
, which fiber connector outlet
947
is connected to a second fiber converter
946
through a fiber optical cable
904
and then to a switch-hub
944
through another unshielded twisted pair cable
945
and then to a router
901
through another unshielded twisted pair cable
943
and then to the server
941
through another unshielded twisted pair cable
942
. The aforesaid conventional methods have common drawbacks as outlined hereinafter.
1. Because a big number of members are used (fiber converters
916
;
919
;
946
;
949
, fiber jumper patch cord
918
;
948
and fiber connector outlet
917
;
947
), the installation cost is high, and much installation space is required.
2. Because a big number of members are used the installation procedure is complicated, any connection error of either member (fiber converters

;
919
;
946
;
949
, fiber connector outlet
917
;
947
, fiber jumper patch cord
918
;
948
, fiber optical cables

;
902
;

;
913
;
915
, unshielded twisted pair cables

) causes an installation failure.
The present invention has been accomplished to provide a fiber converter box, which eliminates the aforesaid drawbacks. It is one object of the present invention to provide a fiber converter box, which achieves the work of multiple fiber converters. It is another object of the present invention to provide a fiber converter box, which saves much installation labor and time in connecting a personal computer to a server. According to one aspect of the present invention, the fiber converter box has 8 slots in the vertical front panel of the box body thereof for the mounting of 8 circuit board assemblies, enabling the fiber converter box to achieve the work of 8 conventional fiber converters. According to another aspect of the present invention, the user can change the number of the number of circuit board assemblies to fit different requirements. According to still another aspect of the present invention, the fiber converter box has a top cover board covering the box body, which top cover board has a downwardly extended back plate with two holes coupled to a power switch and an alternating current socket of the box body. Therefore, the user must disconnect the plug of the power cable from the alternating current socket of the box body before dismounting the top cover board from the box body to prevent an accident during a repair or maintenance work of the fiber converter box.
