Device for data transmission
View Patent ↗Devices are provided including an SFP interface and a further interface for wire-based data transmission. A conversion circuit converts between SFP interface signals and wire-based interface signals. The interfaces and the conversion circuit may be, but need not be, provided on a same circuit board.
1. A device, comprising:
an SFP interface, and
a wire-based interface for wire-based data transmission, the wire-based interface comprising:
an Ethernet interface; and
a digital subscriber line (DSL) interface;
wherein the Ethernet interface is allocated to a data link layer and the DSL interface is allocated to a physical layer; and
a conversion circuit for converting signals between an SFP interface and the wire-based interface.
2. The device according to claim 1 , the DSL interface comprising an xDSL interface.
3. The device according to claim 2 , wherein xDSL is one of VDSL2, SHDSL or G.fast.
4. The device according to claim 1 , the interfaces and the conversion circuit being arranged on a single circuit board.
5. The device according to claim 4 , the shape of the device adjacently to the SFP interface being selected in such a manner that it can be inserted into an SFP plug-in location.
6. The device according to claim 5 , the device being arranged in a corresponding housing.
7. The device according to claim 1 , the conversion circuit comprising conventional semiconductor components.
8. The device according to claim 1 , the conversion circuit comprising an SGMII interface circuit which provides signals for the SFP interface.
9. The device according to claim 1 , the conversion circuit comprising an xDSL chip.
10. The device according to claim 9 , the conversion circuit comprising a memory for the xDSL chip.
11. The device according to claim 9 , xDSL being VDSL2, SHDSL or G.fast.
12. The device according to claim 1 , the SFP interface comprising conductor tracks on a circuit board which form a male connector.
13. The device according to claim 4 , wherein the circuit board has a smaller width at the SFP interface than at the wire-based interface.
14. A device, comprising:
a printed circuit board having a relatively smaller width portion and a relatively larger width portion,
an SFP interface arranged on the circuit board at the relatively smaller width portion, and
a wire-based interface arranged on the circuit board at the relatively lager width portion for wire-based data transmission, the wire-based interface comprising:
an Ethernet interface; and
a digital subscriber line (DSL) interface; wherein the Ethernet interface is allocated to a data link layer and the DSL interface is allocated to a physical layer; and
a conversion circuit for converting signals arranged on the circuit board between an SFP interface and the wire-based interface.
15. The device according to claim 14 , the interface comprising an xDSL interface.
16. The device according to claim 14 , the circuit board being a single circuit board.
17. The device according to claim 14 , the width of the relatively smaller width portion being such that it can be inserted into an SFP plug-in location.
18. The device according to claim 14 , the SFP interface comprising conductor tracks on the circuit board which form a male SFP connector.
