Abstract

A connector may mate with low density and high density pcb modules. The connector may be formed with rows 41, 42 of connecting contacts, one row 42 being behind the another 41 in the mating direction, the connector being arranged so that a high density pcb card 52 can contact both rows by penetrating the one to reach the other, and a low density pcb card can contact only the one row. The cards may be optical I/O cards. Further rows of contacts may be provided as needed.

Description

24 1 4347 High Density Electrical Connector Apparatus The present
invention relates to an electrical connector, in particular to a highdensity electrical comlector that is compatible with both existing low density and new high- density T/O optical modules. The invention Is relevant to pluggable electrical/optical and/or electrical/electrical transceiver modules with a high-density form factor.
Figure I and 3 illustrate a typical know transceiver assembly. Most optical transceivers contain at Icast one printed circuit board that mates with a connector on the users host board. Several types of standard connectors can be employed, most utilizing the concept of spring fingers to make contact with pads on the PCB.
As the demand for increased port density on optical network systems increases, so too does the number of T/O outlets required. To satisfy the demand for increased port density, a new form of electrical connector and PCT3 layout must be devised. This new arrangement must facilitate the increased 1/0 density whilst maintaining the current form factors, and critically, is compatible with both new and current form factors.
It is an object of the present invention to the address the abovementioned technical issues.
According to the present invention there is provided an electrical connector apparatus suitable for both low-density and high-density electrical interconnects, the apparatus comprising a host PCB having disposed thereon a plurality of electrical connection means for providing electrical connection from the host PCB to a module PCB.
Advantageously the present invention is fully compatible with both new and existing form factors, but which allows for a much higher 1/0 density than the existing connection arrangement.
While the principle advantages and features of the invention have been described above, a greater understanding and appreciation of the invention may be obtained by referring to the drawings and detailed description, presented by way of example only, in which; FIGURE I shows an example of a know transceiver electrical connection arrangement, FIGURE 2 shows a transceiver with a high 1/0 density, FIGURE 3 shows a side view of the know transceiver electrical connection arrangement shown in figure l, FIGURE 4 show a side view of the electrical connection arrangement according to the present invention, FIGURE 5 shows a further embodiment of the electrical connection arrangement according to the present invention, and FIGURE 6 shows an example of the pin outs for a module PCB according to the present invention.
As customers requirements for increased optical port density (i.e. optical output/inputs) increases, the number of electrical connections to the host PCB also increases as seen in figure 2.
Figure 4 shows a schematic depiction of an electrical connector and PCB, according to the present invention that is fully compatible with both new and existing form factors, but which allowing for a much higher LO density than the existing arrangement. This is achieved by having a plurality of electrical connection means 41 and 42 disposed on the host PCB wherein the electrical connection means are coplanar.
As seen in figure 5, the present invention advantageously allows a standard low density TO module 51 to be connected to the host board, but can also facilitate a high density I/O module 52. This ensures that the connector is fully compatible, facilitating both high and low-density modules.
Advantageously the present invention only requires a single PCB to achieve electrical connection to the high-density modules. Utilizing a single l'CB offers several advantages including cost, space saving, simplification of design and processing.
Figure 6 illustrates a schematic depiction of PCB layout according to the present invention. Electrical contact to the connector pins is made through rows of metalised pads 62 and 63 on the PCB. Routing to these pads may be on the top layer of the PCB or through vies 64 on the PCR.
Both figures 5 and 6 show a connector with two sets of interconnects. The invention is not limited k'just two sets of interconnects. The invention could be extend to include any number ot sets interconnects and rows, whilst maintaining backward compatibility where appropriate.
It is not intended that the present invention be limited to the above embodiments and other modifications and variations are envisaged within the scope of the claims.
