QSFP28 cables are high-speed, quad-small form-factor pluggable (QSFP) transceiver cables used in data centers and other networking applications. They provide a compact and efficient interface for transferring large amounts of data quickly and reliably. This article looks closely at QSFP28 technology and explores its key features and benefits.
QSFP28 cables consist of four optical lanes that transmit data up to 28Gbps per lane. This makes them well-suited for high-bandwidth applications like cloud computing, machine learning, and extensive data analysis. The cables use a compact form factor that saves space and reduces power consumption, essential for large-scale data center deployments.
The QSFP28 transceiver form factor is based on the QSFP+ standard with additional features enabling higher transmission speeds. QSFP28 cables are backward-compatible with QSFP+ connectors, but they offer more bandwidth and can transmit data over longer distances. The wires also support a more comprehensive range of protocols and applications, including Ethernet, InfiniBand, and Fibre Channel.
There are two types of QSFP28 cables: passive and active. Passive cables provide a direct electrical connection between the transceivers without signal amplification or regeneration. Active lines use an integrated circuit to amplify the signals and extend the transmission distance. The choice between passive and active lines depends on the required transmission distance and the type of interface used.
QSFP28 cables offer several benefits over other types of transceiver cables. They provide faster transmission speeds and higher bandwidth, essential for handling large volumes of data. They also have a smaller form factor and lower power consumption, which reduces the cost and complexity of data center deployments. In addition, QSFP28 cables are easy to install and maintain, thanks to their plug-and-play design.
QSFP28 cables are similar to other QSFP transceiver cables but have some key differences. They have a higher transmission speed and support broader applications and protocols. They are also more compact and energy-efficient, which makes them ideal for data center deployments. However, they may not be compatible with all types of equipment, so checking compatibility before using them in a particular application is essential.
In conclusion, QSFP28 cables are a powerful and efficient technology for data centers and networking applications. They offer fast transmission speeds, a compact form factor, and a range of advanced features that make them ideal for handling large volumes of data. Whether building a new data center or upgrading an existing one, QSFP28 cables are an intelligent choice for high-performance networking.
In networking, QSFP28 cables are crucial in transmitting signals between different devices. But did you know that there are different types of QSFP28 cables available? This article will examine the various kinds of QSFP28 cables and their unique functions.
The QSFP28 Passive Copper Cable, also known as PCC, is a type of QSFP28 cable made of copper and has a passive design. This cable type is mainly used for short-reach connections and has a maximum distance capability of 7 meters. Its passive design requires no power, making it a cost-effective solution.
Like the PCC, the QSFP28 Passive Direct Attachment Copper (DAC) cable is also a passive design QSFP28 cable. However, unlike the PCC, the Passive DAC cable has a more extended distance capability of up to 15 meters. This cable type is commonly used for multiple short-reach connections and is another cost-effective solution.
The QSFP28 to QSFP28 Direct Attach Copper Cable is a QSFP28 cable designed to connect two QSFP ports directly. This cable type can offer a transmission distance of up to 5 meters. This cable type is mainly used in high-density networking applications and is not as cost-effective as passive designs since it requires signal amplification and conditioning.
The 100G QSFP28 Passive Direct Attach Copper Cable is a passive design QSFP28 cable capable of supporting high-speed data transmission of up to 100Gbps. This cable type is used for medium to long-reach connections, with a maximum distance capability of 30 meters. Due to its robustness and reliable design, this cable type is commonly used in data centers.
The 100G QSFP28 Passive DAC Cable is very similar to the 100G QSFP28 Passive Direct Attach Copper Cable, with the only difference being that the 100G QSFP28 Passive DAC Cable has a more extended distance capability of up to 50 meters.

In conclusion, QSFP28 cables come in different types, each with unique characteristics and suitability for various networking applications. The kind of QSFP28 cable you choose will depend on the specific needs of your networking environment.
QSFP28 cables, or Quad Small Form-Factor Pluggable 28-Gigabit cables, are high-speed network cables commonly used in data center applications. They are designed to transmit data at fast rates of up to 100 Gbps, making them an essential component for modern networks. These hot-swappable cables can be plugged in and removed while the network runs, reducing downtime and maintenance costs.
When choosing QSFP28 cables, it’s vital to consider the compatibility of your devices and transceivers. QSFP28 cables are incompatible with all devices and transceivers, so checking the manufacturer’s compatibility list before purchasing is crucial. Choosing the suitable cable compatible with your devices and transceivers can prevent network issues, including intermittent disconnections, performance degradation, and data loss.
Multisource Agreements (MSAs) and industry standards are also crucial considerations when selecting QSFP28 cables. MSAs are agreements made among manufacturers to establish interoperability and compatibility between manufacturers’ devices and transceivers. These agreements help ensure that products from other manufacturers work together seamlessly. Furthermore, adhering to industry standards ensures network efficiency and compatibility across other equipment manufacturers.
Cisco is a leading provider of networking equipment. They have developed a series of compliance standards to ensure compatibility with their devices and transceivers. Cisco-compliant QSFP28 cables are tested and verified to ensure they are compatible with Cisco devices. Compliant cables can reduce compatibility complaints and incompatibility issues, protecting your network investment.
When selecting QSFP28 cables, generic and OEM models are available. Generic cable models are usually less expensive but may not have undergone the same testing processes as OEM models. OEM cables are less likely to cause compatibility issues but are more costly than generic cables. Before making a purchase decision, consider each cable’s origin, testing, and warranty, ensuring it meets your needs.
