Coupling invertible and pluggable module to a circuit board
A system including a circuit board and several pluggable modules coupled to the circuit board. The several pluggable modules are insertable through side-by-side slots in an enclosure in which the circuit board resides. A first pluggable module is coupled to the circuit board via a first connector, while a second pluggable module is coupled to the circuit board via a second connector such that the second pluggable module is laterally offset from the first pluggable module. The first and second connectors are right angle connectors, and the second right angle connector is inverted relative to the first right angle connector. The first and second pluggable modules are I/O modules for transporting high speed differential signals, and wherein the first pluggable module includes several XFP connectors, and wherein the second pluggable module includes several SFP connectors. The second pluggable module includes several SFP connectors arranged on both sides of the pluggable module.
1. A method comprising the steps of:
coupling a first pluggable module to a circuit board via a first connector, the circuit board residing in an enclosure having side-by-side slots thereon for inserting pluggable modules therethrough for coupling to the circuit board, such that when the first pluggable module is coupled to the circuit board through one of the side-by-side slots, it resides side-by-side but laterally offset from a second pluggable module coupled to the circuit board through another of the side-by-side slots,
wherein the second pluggable module is coupled the circuit board via a second connector, and wherein the first and second connectors are right angle connectors, and wherein the step of coupling the first pluggable module to the circuit board includes the step of coupling the first pluggable module to the circuit board via a first right angle connector such that the first right angle connector is inverted relative to the second right angle connector, and
wherein the first and second pluggable modules are input/output (I/O) modules for transporting high speed differential signals, and wherein the first pluggable module includes a first number of connectors of a first size, and wherein the second pluggable module includes a second number of connectors of a second size, and wherein the first number is less than the second number, and wherein the first size is larger than the second size.
2. The method of claim 1 , wherein the second number of connectors are small form pluggable (SFP) connectors arranged on both sides of the second pluggable module.
3. The method of claim 1 , wherein the first number of connectors are 10 Gigabit small form factor pluggable (XFP) connectors arranged on one side of the first pluggable module.
4. The method of claim 1 , wherein the second pluggable module is a small form pluggable (SFP) module which is constructed and arranged to communicate with the circuit board through the second connector.
5. The method of claim 1 , wherein the first pluggable module is a 10 Gigabit small form factor pluggable (XFP) module which is constructed and arranged to communicate with the circuit board through the first connector.
