Description

A kind of device of photoelectric interface duplex

Technical field

The utility model relates to networking technology area, particularly relates to a kind of device of photoelectric interface duplex.

Background technology

There are multiple demands such as pure optical interface, pure electrical interface, optic electric interface mixing in the optic electric interface of current Ethernet.And the prior art solution to be a veneer only support optical interface, a veneer only to support electrical interface, perhaps on veneer, preestablish the quantity of optical interface and electrical interface, adopt the mode of plug-in card to support.Concrete as Fig. 1, Fig. 2 and shown in Figure 3.For the mode that these two kinds of Fig. 1 and Fig. 2 only support a kind of interface, its shortcoming is to lack flexibility, can't support the photoelectricity mixed insertion.Mode for this veneer plug-in card of Fig. 3, its shortcoming is the quantity that will configure optical interface and electrical interface in advance, if the quantity of optical interface or electrical interface changes, then need veneer is carried out rewiring, cause PCB (Print circuitboard, printed circuit board) kind is many, the product structure complexity, and cost increases.

The utility model content

The utility model embodiment provides a kind of device of photoelectric interface duplex, realize pure optical interface, pure electrical interface, multiple product form demands such as optic electric interface mixing by a veneer and PHY (physical layer physical layer) chip, reduce the PCB kind, reduce and produce and safeguard complexity.

The utility model embodiment proposes a kind of device of photoelectric interface duplex, comprising:

Interface board comprises optical interface and electrical interface;

PHY chip, its pin link to each other with electrical interface with the optical interface of described interface board respectively, and judge that according to the numerical value of output pin linking to each other with described optical interface this moment still is to link to each other with described electrical interface.

The technical scheme of the utility model embodiment realizes pure optical interface by a veneer and PHY chip, pure electrical interface, and multiple product form demands such as optic electric interface mixing reduce the PCB kind, reduce and produce and safeguard complexity.

Embodiment

The utility model embodiment provides a kind of device of photoelectric interface duplex, realizes multiple product form demands such as pure optical interface, pure electrical interface, optic electric interface mixing by a veneer and PHY chip, reduces the PCB kind, reduces and produces and safeguard complexity.

The utility model embodiment specifically comprises as shown in Figure 4, comprising:

Interface board comprises optical interface and electrical interface;

PHY chip, its pin link to each other with electrical interface with the optical interface of interface board respectively, and judge that according to the numerical value of A0 pin linking to each other with optical interface this moment still is to link to each other with electrical interface.

In order more clearly to describe the structure of interface board,, describe in further detail below in conjunction with Fig. 5 and Fig. 6:

As shown in Figure 5, optical interface and electrical interface are arranged on the interface board, and make electrical interface and optical interface be placed on the same position and the pin mutually noninterfere of interface board, particularly, its topology layout is furnished with the optical interface position that the fixing hole size is certain and spacing is identical in the one side of interface board as shown in Figure 6, shown among Fig. 61, concrete, the optical interface that connects on this optical interface position can be SFP (Small Form-factor Pluggables, a miniature pluggable module) light opening connector; Corresponding interface board another side is furnished with the electrical interface position, and shown among Fig. 62, the optical interface position of its fixing hole size and spacing and another side is just the same, concrete, and the electrical interface that connects on this electrical interface position can be a RJ45 electricity opening connector.Such layout can make electric opening connector and light opening connector pin simultaneously on PCB and mutually noninterfere.

As shown in Figure 7,, can define some pins of PHY chip and link to each other with optical interface in the interface board according to the difference of actual conditions, as Ai to the pin between the Am; Other pins link to each other with electrical interface in the interface board, as Am to the pin between the An.When the output A0 pin in the PHY chip was 0, what represent PHY chip connection this moment was optical interface; When the output A0 pin in the PHY chip was 1, what represent PHY chip connection this moment was electrical interface, and vice versa.Certainly, according to the difference of configuration around the PHY chip, can determine that the PHY chip was connected with optical interface or was connected with electrical interface this moment with other output pin equally.

The technical scheme of the utility model embodiment has the following advantages, and realizes pure optical interface by a veneer and PHY chip, pure electrical interface, and multiple product form demands such as optic electric interface mixing reduce the PCB kind, reduce and produce and safeguard complexity.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be looked protection scope of the present invention.
