[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 20, 2023, with application number 202311764063.X, and application name “A High-Speed ​​Optical Communication Connector and Server”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of data transmission, and in particular to a high-speed optical communication connector and a server. Background Art

[0004] QSFP28 is a high-speed fiber optic transmission module and a common fiber optic interface standard in modern communication networks. The QSFP28 standard defines a high-performance fiber optic transmission module whose physical interface utilizes an embedded interface structure. This interface structure supports up to 28 channels of data transmission, with each channel capable of transmitting at a rate of up to 25Gbit / s. Therefore, the QSFP28 module can achieve an overall transmission rate of up to 700Gbit / s.

[0005] 100G fiber optic network ports are now increasingly common, with 100G port modules available in a variety of form factors, including CFP / CFP2 / CFP4, CXP, and QSFP28. Among these various 100G form factors, the QSFP28 optical module has become the primary form factor for 100G networks due to its advantages, including high port density, low power consumption, and low cost. The QSFP28 utilizes 4 x 25Gbps channels. Furthermore, the QSFP28 optical module features upgraded electrical ports that support up to 28G signals, achieving a maximum possible rate of 4 x 28Gbit / s. The 100G QSFP28 form factor is smaller than the CXP CFP4 optical module, enabling higher port density on switches.

[0006] PCI-Express (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard. PCIe is a high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices are allocated exclusive channel bandwidth and do not share bus bandwidth. It mainly supports active power management, error reporting, end-to-end reliable transmission, hot plugging, and Quality of Service (QOS) functions.

[0007] However, the current QSFP28 interface is not compatible with the PCIe protocol, resulting in low transmission efficiency of PCIE bus data and waste of network infrastructure resources.

[0070] In order to more clearly illustrate some embodiments of the present application, the following will briefly introduce the drawings required for use in some embodiments. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0076] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0077] In practical applications, solid-state drives (SSDs), which use flash memory as their storage medium and offer faster read speeds than mechanical hard drives, are poised to become the preferred storage option for data centers and cloud computing due to their high storage performance and energy savings. SSD interfaces are categorized by protocol as either SATA or NVMe, which relies on the PCIe bus. NVMe (Non-Volatile Memory Express) is an industry-wide standard designed specifically for PCIe-based SSDs. Leveraging the high bandwidth and low latency of the PCIe bus, NVMe replaces the traditional SATA and SAS SSD storage architectures, offering faster read and write speeds, lower latency, and lower power consumption. It has become a mainstream development direction in the future storage industry. SSDs connect to the motherboard's PCIe interface in various connector formats, including U.2 and M.2. These are mostly dedicated interfaces for storage and rarely serve other functions.

[0078] In the ever-changing era of big data networks, the importance of real-time data will become increasingly important. Sometimes, hosts will need to conduct more network interactions, increasing network bandwidth. This increased network bandwidth also requires more data storage space, but network bandwidth and data storage are not necessarily equal. At some stage, network data may need to be stored, which requires a very large storage space. However, the stored data has a short validity period and the storage space can be released after a period of time, that is, the large storage space is no longer needed. As a result, there are situations where storage applications sometimes take priority and network bandwidth requirements sometimes take precedence. Faced with this situation, PC hosts or server systems need to be equipped with more network interfaces, switches, and storage interfaces, and even deploy large-scale distributed networks.

[0079] If the high-speed optical communication interface and PCIe interface, which are the two pillars of the industry, can be designed to be compatible, so that the network and storage can intersect on the interface, a new application method will emerge, providing PC hosts with arbitrary network expansion or storage expansion, which is plug-and-play and does not require power-on maintenance or interface replacement.

[0080] Therefore, the embodiment of the present application proposes a high-speed optical communication connector QSFP28-PCIE that supports the PCIe protocol, making the current mainstream 100G QSFP28 network interface compatible with the PCIe interface, so that the network interface and the NVNe hard disk interface can be compatible with the same physical interface, thereby further promoting the integration of network and storage on the interface, and connecting the two pillar data transmission technologies of optical communication and PCIe protocol to achieve free switching in different application scenarios.

[0081] 1 , a schematic structural diagram of a high-speed optical communication connector provided in an embodiment of the present application is shown:

[0082] In practical applications, the host device may be a server or a personal computer (PC).

[0083] In a specific implementation, the high-speed optical communication connector can be configured to connect a host device to an optical module device, or to connect a host device to a non-volatile memory standard device. For example, the optical module device can be a device that transmits data via optical signals, such as an optical interface switch, and the non-volatile memory standard device can be a device that complies with non-volatile memory standards, such as a solid-state drive (SSD).

[0084] When the host device and the optical module device are connected, the host device may be configured to generate a module low-speed signal MODSEL and an optical module reset signal RESET.

[0085] When the host device and the nonvolatile memory standard device are connected, the host device may be configured to generate a negative clock signal CLK_N and a positive clock signal CLK_P.

[0086] In actual applications, the main difference between the PCIE interface and the optical communication interface is that the PCIE interface generally requires a pair of external 100Mhz reference clock signals. The embodiment of the present application can multiplex the MODSEL and RESET signals of the high-speed optical communication connector into a reference clock output signal to provide a 100MHz reference clock for the NVMe hard drive.

[0087] The high-speed optical communication connector of the embodiment of the present application may include:

[0088] A first signal pin 101 for a module low-speed signal MODSEL or a negative clock signal CLK_N;

[0089] A second signal pin 102 for the optical module reset signal RESTE or the positive clock signal CLK_P.

[0090] The first signal pin 101 may be configured to transmit the module low-speed signal MODSEL sent by the host device to the optical module device when the host device and the optical module device are connected;

[0091] The second signal pin 102 may be configured to transmit the optical module reset signal RESET sent by the host device to the optical module device when the host device and the optical module device are connected;

[0092] The first signal pin 101 may be configured to transmit a negative clock signal sent by the host device to the non-volatile memory standard device when the host device and the non-volatile memory standard device are connected;

[0093] The second signal pin 102 may be configured to transmit a positive clock signal sent by the host device to the non-volatile memory standard device when the host device and the non-volatile memory standard device communicate with each other.

[0094] In a specific implementation, the embodiment of the present application can use devices such as QSFP28 or QSFP56 as the initial high-speed optical communication connector, and add relevant signal definitions of the PCIE X4 interface on the basis of the initial high-speed optical communication connector to achieve physical interface compatibility. In order to enable those skilled in the art to better understand the embodiment of the present application, QSFP28-PCIE is used as an example of a high-speed optical communication connector for explanation below.

[0095] As shown in Figure 1, the high-speed optical communication connector QSFP28-PCIE, based on the input and output modes of the optical signal, considers the input and output modes of the compatible PCIE interface, and can redefine a compatible PCIE interface signal definition. Among them, for high-speed signal lines, I2C buses, power supplies and most signal definitions and usages, QSFP28 and PCIE can be the same, and the interface level standards are almost the same. For example, the signal lines of the QSFP28 and PCIE interfaces are all high-speed serial buses, divided into four groups of unidirectional input RX[1:4] differential buses and four groups of unidirectional output TX[1:4] differential buses. The bus specifications can be consistent with the QSFP28 interface.

[0096] The QSFP28 high-speed connector supports an interface line speed of up to 28G signal rate and is backward compatible with the 16G signal of the PCIE4.0 interface. The high-speed connector signal form is available, and the host-side or switch-side application can redefine the interface to achieve protocol compatibility. The field-editable gate array FPGA can implement the definition of the pin protocol content, so that the interface application can be freely selected by the field-editable gate array FPGA, and seamless compatible design can be achieved. For example, the field-editable gate array FPGA can define the high-speed optical communication connector QSFP28-PCIE to support free switching of optical port protocol and PCIE protocol in the same physical port, which can include defining the first signal pin of the high-speed optical communication connector QSFP28-PCIE to realize the multiplexing of the module low-speed signal or negative clock signal, and the second signal pin to realize the multiplexing of the optical module reset signal or positive clock signal. This process can be implemented inside the field-editable gate array FPGA main controller.

[0097] In some embodiments, channel selection for optical module devices and non-volatile memory standard devices can be achieved through two methods:

[0098] 1. Through hardware gating, that is, using resistors or capacitors to perform signal gating, or through high-speed analog switches to perform signal gating;

[0099] Second, compatibility selection is made through the internal signals of the CPU controller or FPGA controller. Specifically, as a programmable device, FPGA has greater advantages when the CPU has not yet developed this function. FPGA devices can define high-speed signal channels as PCIe interface channels or optical Ethernet high-speed signal channels as needed. Therefore, it is only necessary to connect the high-speed signal line on the connector to the FPGA high-speed signal channel, and then the FPGA can define whether the interface is a high-speed network interface or a PCIE bus interface according to the actual application.

[0100] Of course, the above examples are only examples, and those skilled in the art may use any other method to implement channel selection for the QSFP28 interface and the PCIE interface, and the embodiments of the present application are not limited to this.

[0101] When it is determined that the host device and the optical module device are connected, the module low-speed signal MODSEL and the optical module reset signal RESET are input signals relative to the optical module. For example, they can be pulled up to the VCC power supply of the optical module through a pull-up resistor. When the host outputs a low level to the optical module, the optical module is selected or reset.

[0102] When it is determined that the host device and the non-volatile memory standard device are connected, the high-speed optical communication connector QSFP28-PCIE can receive the reference clock signal CLK_N (negative clock signal) / CLK_P (positive clock signal) from the host. CLK_N (negative clock signal) / CLK_P (positive clock signal) is also an input signal for the NVMe SSD hard drive.

[0103] From the above, it can be seen that no matter whether the high-speed optical communication connector QSFP28-PCIe of the embodiment of the present application is connected to an optical module or an NVMe hard drive, the CLK_N / MODSEL and CLK_P / RESET signals are input signals for the external device, and are output signals for the motherboard with the high-speed optical communication connector QSFP28-PCIe of the embodiment of the present application. Therefore, no matter whether the application function is the PCIE bus or the optical port signal mode, any external interface will not cause damage to each other.

[0104] In some embodiments, by enabling the first signal pin to realize multiplexing of the module low-speed signal MODSEL and the negative clock signal, and enabling the second signal pin to realize multiplexing of the optical module reset signal or the positive clock signal, the high-speed optical communication connector including the first signal pin and the second signal pin can be compatible with both optical signal data transmission and PCIe protocol signal transmission, thereby realizing the long-distance data transmission of PCIE bus data based on the existing optical fiber network, improving the transmission efficiency of PCIE bus data, and avoiding the waste of resources of existing network infrastructure.

[0105] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.

[0106] In one embodiment of some embodiments of the present application, the host device is provided with a field-editable gate array, which is configured to receive an in-situ detection input signal generated by an optical module device or a non-volatile memory standard device, and when the in-situ detection input signal is received, establish a connection relationship between the host device and the optical module device based on the in-situ detection input signal, or establish a connection relationship between the host device and the non-volatile memory standard device based on the in-situ detection input signal.

[0107] In practical applications, FPGAs (Field Programmable Gate Arrays) are a further development of programmable devices such as PALs (Programmable Array Logic) and GALs (General Array Logic). They emerged as a semi-custom circuit within the field of application-specific integrated circuits (ASICs), addressing both the shortcomings of custom circuits and the limited number of gates inherent in existing programmable devices.

[0108] From the above, we can see that as a programmable device, field-programmable gate array logic (FPGA) has greater advantages when the CPU has not yet developed the channel selection function. FPGA devices can define high-speed signal channels as PCIe interface channels or optical Ethernet high-speed signal channels as needed. Therefore, it is only necessary to connect the high-speed signal line on the connector to the field-programmable gate array FPGA high-speed signal channel, and then the field-programmable gate array FPGA can define whether the interface is a high-speed network interface or a PCIE bus interface according to the actual application.

[0109] Specifically, when the optical module device or the non-volatile memory standard device generates an in-situ detection input signal MODPRSL, the field-editable gate array FPGA can receive the in-situ detection input signal MODPRSL. If the host device currently connected to the optical module device is a host device, the in-situ detection input signal MODPRSL can be grounded in the optical module device, pulled up by the host device, and connected to the input and output IO of the field-editable gate array FPGA to determine that the in-situ device is an optical module device. If the host device currently connected to the non-volatile memory standard device is a host device, the in-situ detection input signal MODPRSL can be grounded in the non-volatile memory standard device, pulled up by the host device, and connected to the input and output IO of the field-editable gate array FPGA to determine that the in-situ device is a non-volatile memory standard device, thereby achieving compatibility between the two transmission protocols.

[0110] In some embodiments, the host device's input and output IO signals are analog outputs, and the FPGA can select clock compatibility with MODSEL and RESET signals (CLK_N / MODSEL and CLK_P / RESET). Because MODSEL and RESET are input signals to the optical module, even when the FPGA is configured as a PCIE interface, the output clock signal is connected to the optical module without causing damage to the optical module or the field-programmable gate array FPGA.

[0111] In some embodiments of the present application, a field-editable gate array is provided for a host device, and the field-editable gate array is configured to receive an in-situ detection input signal generated by an optical module device or a non-volatile memory standard device, and when the in-situ detection input signal is received, a connection relationship between the host device and the optical module device is established based on the in-situ detection input signal, or a connection relationship between the host device and the non-volatile memory standard device is established based on the in-situ detection input signal, thereby improving the channel selection efficiency for the optical module device and the non-volatile memory standard device, and further improving the data transmission efficiency.

[0112] In some embodiments of the present application, a high-speed optical communication connector includes:

[0113] an eighth signal pin for a presence detection input signal;

[0114] The eighth signal pin is configured to transmit a presence detect input signal to the host device.

[0115] Refer to FIG2 , which is a schematic structural diagram of another high-speed optical communication connector provided in some embodiments of the present application;

[0116] In a specific implementation, some embodiments of the present application can define the eighth signal pin 103 through a field-programmable gate array FPGA, so that the in-situ detection input signal for the optical module device and the in-situ detection input signal for the non-volatile memory standard device can be multiplexed on the eighth signal pin 103, so that the in-situ detection input signal for the optical module device and the in-situ detection input signal for the non-volatile memory standard device can both be transmitted to the host device through the eighth signal pin 103, saving the pin occupation of the high-speed optical communication connector, thereby further improving the data transmission efficiency.

[0117] In some embodiments of the present application, a high-speed optical communication connector includes:

[0118] A third signal pin providing a signal receiving power supply voltage;

[0119] a fourth signal pin providing a signal transmission power supply voltage;

[0120] A fifth signal pin that provides a low-speed signal power supply voltage.

[0121] In practice, the I2C bus is a simple, bidirectional, two-wire synchronous serial bus. It requires only two wires to transmit information between connected devices. A master device is configured to initiate bus data transfer and generate a clock to open the bus for transmission. At this point, any addressed device is considered a slave. The relationship between master and slave, sender and receiver, on the bus is not constant, but depends on the direction of data transmission. To send data to a slave, the master first addresses the slave, then actively sends data to the slave, and finally terminates the data transfer. To receive data from a slave, the master first addresses the slave, then receives the data sent by the slave, and finally terminates the reception process. In this case, the master is responsible for generating the timing clock and terminating the data transfer.

[0122] Solid State Disk (SSD), also known as solid-state drive, is a hard disk made of solid-state electronic storage array.

[0123] In a specific implementation, the host device provides power to the optical module through three 3.3V power supplies: the receive power supply VCCRX, the transmit power supply VCCTX, and the low-speed signal power supply VCC1. These power supplies operate within a 3.3V ±5% range and consume 1.5-10W of power. These three power supplies can be reused to power solid-state drives (SSDs), which also require a 3.3V ±5% power supply. Depending on the capacity and speed, SSDs typically consume approximately 2-10W of power. The I2C bus SCL (Serial Clock Line) and SDA (Serial Data Line) signals operate in the same manner, with a 3.3V interface level and the same universal I2C protocol. This allows FPGAs to simulate the I2C bus and read optical module information or NVMe SSD information, ensuring full I2C bus compatibility.
