Why A QSFP28 Breakout Cable

200G | 400G | Important Trends and Applications

With the increasing demand for high-speed internet and data transfer, companies need reliable and efficient solutions to meet their connectivity needs. This is where the QSFP28 breakout cable comes into play. 

  • With the increasing demand for higher data speeds, the traditional copper cables were no longer able to keep up. 
  • This led to the development of fibre optic cables, which offered much faster data transmission rates.  

However, these cables required additional equipment such as transceivers and switches, making them more expensive and complex to install. 

What is the purpose of a breakout cable? 

The primary purpose of a breakout cable is to unlock the full potential of QSFP28 ports. These ports have four lanes, each capable of transmitting data at a rate of 25G.  

However, traditional copper cables can only utilize one of these lanes, limiting the data transmission rate to 25G. 

  • On the other hand, a QSFP28 DAC Breakout Cable has four lanes, each capable of transmitting data at a rate of 50G, resulting in a total data transmission rate of 200G or 400G.  
  • This makes it a much more efficient and cost-effective solution compared to traditional copper cables. 

How do QSFP breakout cables work? 

A QSFP breakout cable takes the four channels of data and breaking them out into four separate connections.  

  • This is accomplished by using a special breakout module that is attached to the QSFP cable.  
  • The breakout module has four separate ports, each of which corresponds to one of the four channels in the QSFP cable.  
  • These ports can then be connected to separate devices, such as switches or servers, allowing for high-speed data transmission between them. 

Why are QSFP breakout cables important? 

QSFP breakout cables are important because they allow higher bandwidth and faster data transmission between devices.  

Problems with the traditional method 

In the past connecting multiple devices in a network required separate cables for each connection, which could quickly become a tangled mess.  

QSFP 28 Cables works via single cable mode 

QSFP breakout cables eliminate this problem by allowing multiple connections through a single cable, making network management much more manageable. 

What is the QSFP28 breakout cable? 

QSFP28 DAC (Direct Attach Copper) breakout cable is a high-performance interconnect solution that provides a cost-effective and flexible alternative to traditional fibre optic cabling.  

  • It is designed to support data rates of up to 400G and is compatible with a wide range of networking equipment.  
  • The cable is terminated with Quad Small Form-factor Pluggable (QSFP) connectors, making it easy to connect and disconnect from devices. 

The QSFP28 200G Breakout Cable 

The QSFP28 200G breakout cable is an ideal solution for data centres that require high-speed connections between switches and servers.  

  • It consists of four separate 50G channels, allowing a total data transfer rate of 200Gbps.  
  • This cable can support a range of network applications, including 40 Gigabit Ethernet, 100 Gigabit Ethernet, and 200 Gigabit Ethernet. 

The QSFP28 400G Breakout Cable 

As data centres continue to evolve, the demand for higher speeds is increasing. This is where the QSFP28 400G breakout cable comes in.  

  • It consists of eight individual 50G channels, providing a total data transfer rate of 400Gbps.  
  • This cable is designed to support various network applications, including 100 Gigabit Ethernet, 200 Gigabit Ethernet, and 400 Gigabit Ethernet. 

Active vs. Passive QSFP28 DAC Breakout Cables 

In addition to the different speeds and data transfer capabilities, QSFP28 DAC breakout cables are also available in active and passive versions.  

The core difference between the two is the type of electronic components used to transmit data 

Active QSFP28 DAC breakout cables use active electronic components, such as integrated circuits, to transmit data, while passive QSFP28 DAC breakout cables use a direct connection without any additional electronics.  

While passive breakout cables are generally more cost-effective, active breakout cables offer better signal integrity and longer transmission distances.

Why A QSFP28 Breakout Cable

FAQ's

Did you know that third-party 100G passive copper cables are compatible with your devices? However, it is important to ensure that these cables meet the necessary IEEE and SFF-8636 specifications to be recognized and utilized effectively by your switch or router.

Did you know that QSFP28 cables are only compatible with 40G, not the other way around? According to a certain protocol, when mixing optical transceivers of different speeds, both ends of the modules must match in terms of form factor. Furthermore, the port speed must be equal or faster than the optic being utilized.

It's a fascinating process in which a single high-speed, channelized port on a network element is transformed into multiple low-speed ports, each leading to numerous other network elements. A switch with 400G ports can be seamlessly connected to 100G ports, making for a truly efficient and powerful network setup.

Did you know that the QSFP28 cable is a versatile communication tool, with not just one but two forms? The first form is a high-speed cable that uses QSFP28 connectors on each end, allowing for the transmission and reception of 100Gbps data through a slim twinax or fibre optic cable.

Whether it's single-mode or multi-mode, breakout is a possibility with both media types.

Yes, breakout cables can be passive (DAC - Direct Attach Cable) using copper wires for shorter distances, or active optical cables (AOC) using lasers for longer reach applications.

While breakout cables offer flexibility and cost advantages in some scenarios, the trend is towards higher speed native QSFP-DD and future transceiver technologies. Breakout cables may be a temporary solution for integrating legacy equipment or maximizing port density in existing setups.

A single QSFP28 lane can support speeds of 25 Gbps. Breakout cables can be configured to provide individual connections of 10 Gbps, 25 Gbps, or a combination depending on the specific cable design and connected devices.
