Description

Technical Field

[0001] The utility model belongs to the technical field of signal transmission devices, and particularly relates to a signal adapter card for a PCIE board. Background Art

[0002] With the rapid development of information technology, especially the popularization of applications such as cloud computing, big data, and artificial intelligence, the requirements for data transmission speed and interface scalability are increasing day by day. Traditional servers and computing platforms often seem inadequate when facing the high-bandwidth and low-latency data transmission requirements. Especially when a large amount of network data and optical port signals need to be processed simultaneously, the design of traditional PCIE boards often has limitations and cannot effectively meet the diversified data transmission needs.

[0003] In the existing design of PCIE boards, common solutions are mainly divided into two categories: one is the network interface card focusing on network data transmission, and the other is the optical port card focusing on optical fiber communication. However, both of these designs have obvious deficiencies.

[0004] For the network interface card, although it can efficiently process network data packets, it lacks support for optical port signals, which is particularly inconvenient in scenarios where optical fiber transmission needs to be processed simultaneously. For example, in data centers or large network nodes, both high-speed Ethernet connections and stable optical fiber transmissions are often required, while traditional network interface cards cannot meet this demand.

[0005] On the contrary, although the optical port card can efficiently process optical fiber signals, it is inadequate in network data transmission. In scenarios where multiple network devices need to be connected simultaneously and complex network management is required, the optical port card cannot provide sufficient flexibility and scalability. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a signal adapter card for a PCIE board to solve the problems existing in the prior art in view of the defects existing in the prior art.

The output end of the network port controller is connected with a plurality of network port sockets, and a network transformer is provided between each network port socket and the network port controller.

[0009] A further improvement of this technical solution is that the optical port controller uses an optical port controller with the model number WX1820AL, and two optical port sockets are connected to the output end of this optical port controller.

This design breaks through the limitation of a single interface of traditional PCIE boards, enabling users to make flexible selections in the face of complex network environments, and greatly improving the efficiency and flexibility of data transmission.

[0015] In addition, the design principle of the present utility model is reliable, the structure is simple, and it has a very broad application prospect.

It is a high-speed serial computer expansion bus standard used to connect high-speed peripherals or expansion cards to the computer motherboard.

[0024] PCIE Switchs, whose full English name is PCI Express Switch, and its Chinese meaning is PCI Express switch or PCIE switch. PCIE Switchs is a hardware device that provides expansion or aggregation capabilities and allows more devices to be connected to a PCIe port. Its main function is to interconnect PCIe devices and communicate through the PCIe protocol.

[0025] As Figure 1 and Figure 2 shown, the present utility model provides a signal transfer card for a PCIE board, including a gold finger connector, a first PCIE Switchs chip, a second PCIE Switchs chip, an optical port controller, a PCIE non-standard connector, a network port controller, and a power interface for powering the entire board; the input end of the gold finger connector is connected to the PCIE board, and corresponding chip enable switches and chip disable switches are provided on both the first PCIE Switchs chip and the second PCIE Switchs chip. A selection switch is provided on the first PCIE Switchs chip. The input ends of the first PCIE Switchs chip and the second PCIE Switchs chip are connected to the same output end of the gold finger connector. The output end of the second PCIE Switchs chip is connected to the input end of the optical port controller. The output end of the optical port controller is connected with a plurality of optical port sockets. The first output end of the first PCIE Switchs chip is also connected to the input end of the optical port controller. The second output end of the first PCIE Switchs chip is connected to the input end of the network port controller. The input end of the PCIE non-standard connector is connected to an external device capable of outputting PCIE signals. The output end of the PCIE non-standard connector is connected to the input end of the network port controller. The output end of the network port controller is connected with a plurality of network port sockets. A network transformer is provided between each network port socket and the network port controller.

[0026] Among them, the optical port controller uses an optical port controller with the model number WX1820AL, and two optical port sockets are connected to the output end of the optical port controller; the network port controller uses a network port controller with the model number WX1860AL2, and two network port sockets are connected to the output end of the network port controller.

[0027] In addition, both the first PCIE Switchs chip and the second PCIE Switchs chip use the PCIE Switchs chip of model PEX8796.

[0028] In addition, a first EEPROM chip is also connected to the network port controller, and a corresponding configuration circuit is also connected to the network port controller.

At the same time, turn the selection switch on the first PCIE Switchs chip to the network port gear. The x4 output by the first PCIE Switchs chip is connected to the network port controller, and the network port controller converts the PCIE signal into a standard two-way network port signal for output.
