The 100G Ethernet card is a high-speed network interface card that can achieve a data transmission rate of 100G per second and is suitable for high-bandwidth application scenarios such as data centers, cloud computing, and artificial intelligence. However, when using a 100G Ethernet card to connect to a switch, you may encounter some problems that affect the performance and stability of the network. This article will introduce some common problems and their solutions, and list some application scenarios.
Problem 1: Switch port speed mismatch
If the port rate of the switch is lower than 100G, such as 10G or 40G, it cannot be directly connected to the 100G Ethernet card, otherwise data loss or errors will occur.
The solution is to use appropriate converters or splitters to decompose the 100G signal into multiple 10G or 40G signals, and then connect them to the switch ports. For example, you can use a QSFP28 to 4*SFP28 converter to decompose the 100G signal into four 25G signals, and then connect them to the four SFP28 ports of the switch.
Application scenario: connection between servers and switches in data centers. If a 100G Ethernet card is installed on the server, and the switch only supports 10G or 40G ports, then you need to use a converter or distributor to convert the 100G signal into a 10G or 40G signal, and then connect it to the switch port to realize data transmission. transmission.
Problem 2: Switch port types do not match
If the port type of the switch is inconsistent with the port type of the 100G Ethernet card, for example, the port of the switch is QSFP28, and the port of the 100G Ethernet card is CFP4, then you cannot directly use the same optical fiber or cable to connect, otherwise it will cause signal incompatibility or Unstable.
The solution is to use appropriate adapters or conversion cables to convert different types of ports to the same type of port, and then use the same type of fiber optic or cable to connect. For example, you can use a QSFP28 to CFP4 adapter to convert the QSFP28 port of the switch to a CFP4 port, and then use CFP4 optical fiber or cable to connect to the CFP4 port of the 100G Ethernet card.
Application scenario: connection between cloud computing servers and switches. If a 100G Ethernet card is installed on the server and the port type of the switch is inconsistent with it, you need to use an adapter or conversion cable to convert the different types of ports into the same type of ports, and then use the same type of optical fiber or cable to connect. Implement data transmission.

Problem 3: Switch port protocols do not match
If the port protocol of the switch is inconsistent with the port protocol of the 100G Ethernet card, for example, the port of the switch is CAUI-4, and the port of the 100G Ethernet card is CAUI-10, then you cannot directly use the same optical module or electrical module for connection, otherwise This can lead to signal incompatibility or instability.
The solution is to use appropriate optical modules or electrical modules to convert ports of different protocols into ports of the same protocol, and then use optical modules or electrical modules of the same protocol to connect. For example, you can use a CAUI-4 to CAUI-10 optical module to convert the CAUI-4 port of the switch to a CAUI-10 port, and then use the CAUI-10 optical module to connect to the CAUI-10 port of the 100G Ethernet card.
Application scenario: connection between artificial intelligence servers and switches. If a 100G Ethernet card is installed on the server and the port protocol of the switch is inconsistent with it, you need to use optical modules or electrical modules to convert the ports of different protocols into ports of the same protocol, and then use optical modules or electrical modules of the same protocol. Make a connection to realize data transmission.
Problem 4: Switch port distance does not match
If the port distance of the switch does not match the port distance of the 100G Ethernet card, for example, the switch port is SR4 and the 100G Ethernet card port is LR4, then you cannot directly use the same type of optical fiber for connection, otherwise it will cause signal attenuation or distortion.
The solution is to use appropriate optical fibers to convert ports at different distances to ports at the same distance, and then use optical fibers at the same distance to connect. For example, you can use an SR4 to LR4 optical fiber to convert the SR4 port of the switch to an LR4 port, and then use the LR4 optical fiber to connect to the LR4 port of the 100G Ethernet card.
Application scenario: connection between big data servers and switches. If a 100G Ethernet card is installed on the server and the port distance of the switch does not match it, then you need to use optical fiber to convert the ports at different distances into ports at the same distance, and then use optical fibers at the same distance to connect to realize data transmission. .
Problem 5: Switch port quality does not match
If the port quality of the switch does not match the port quality of the 100G Ethernet card, for example, the switch port is low-cost, but the 100G Ethernet card port is high-performance, then the same optical module or electrical module cannot be used directly for connection. Otherwise it will cause signal noise or interference.
The solution is to use appropriate optical modules or electrical modules to convert ports of different qualities into ports of the same quality, and then use optical modules or electrical modules of the same quality for connection. For example, high-performance optical modules or electrical modules can be used to convert the low-cost ports of the switch into high-performance ports, and then the high-performance optical modules or electrical modules can be used to connect to the high-performance ports of the 100G Ethernet card.
Application scenario: connection between Internet servers and switches. If a 100G Ethernet card is installed on the server and the port quality of the switch does not match it, you need to use optical modules or electrical modules to convert ports of different qualities into ports of the same quality, and then use optical modules or electrical modules of the same quality. Modules are connected to realize data transmission.
In conclusion, navigating the challenges and implementing innovative solutions is key to unlocking the full potential of 100G Ethernet cards in tandem with switches. With careful consideration and strategic implementation, these technologies become integral components in diverse high-performance networking scenarios.
