Advantages of Using Passive Cables for High-Speed Data Transmission

Passive cables are a popular choice for high-speed data transmission because of several advantages they offer. When it comes to the QSFP-4SFP10G-CU2M= Cisco 2M 40GBASE-CR4 QSFP+ cable, passive cables are an ideal option for several reasons:

  • Cost-effective: Passive cables are generally less expensive than active cables because they do not require any electronics or power to operate. This makes them an ideal choice for short-range applications where active cables would be overkill.
  • Low power consumption: Passive cables do not require any power to operate, which means they consume no energy and do not generate any heat. This makes them an ideal choice for applications where power consumption is a concern.
  • High reliability: Passive cables are simple in design and have no active components, which means they are less likely to fail or cause problems. They also have a longer lifespan compared to active cables, which have more components that can fail over time.
  • Easy to install: Passive cables are plug-and-play, which means they require no setup or configuration. Simply connect the cable to the devices you want to connect, and you're good to go.
  • Low latency: Passive cables have lower latency compared to active cables because they do not require any processing time. This makes them an ideal choice for applications where latency is critical, such as in high-frequency trading or real-time video applications.
  • High bandwidth: Passive cables can support high bandwidths, making them an ideal choice for high-speed data transmission applications. The QSFP-4SFP10G-CU2M= Cisco 2M 40GBASE-CR4 QSFP+ cable, in particular, can support speeds up to 40 Gbps.

High-Performance Computing Environments

The QSFP-4SFP10G-CU2M= Cisco cable is a 2-meter-long copper cable that is designed to support high-speed data transmission in high-performance computing environments. The cable features a QSFP+ connector on one end and four SFP+ connectors on the other end, allowing it to be used to connect a QSFP+ port on a network switch or router to four SFP+ ports on servers, storage devices, or other networking equipment.

Here are some key details about the high-performance computing environments of the QSFP-4SFP10G-CU2M= Cisco cable:

  • Speed: The QSFP-4SFP10G-CU2M= cable supports data transfer rates of up to 40 Gbps, making it ideal for high-performance computing environments that require fast and reliable data transfer.
  • Distance: The cable is designed for use in short-range applications, with a maximum distance of up to 2 meters. This makes it well-suited for use in data centers and other high-density computing environments where devices are located in close proximity to one another.
  • Copper construction: The cable is constructed with copper wire, which provides a high level of durability and reliability. Copper cables are less susceptible to interference and signal loss than other types of cables, which makes them a popular choice for high-performance computing environments.
  • QSFP+ connector: The QSFP+ connector on one end of the cable is a hot-pluggable transceiver that is used to connect the cable to a QSFP+ port on a network switch or router. The QSFP+ connector is designed to support high-speed data transfer and can be used to connect multiple devices together in a high-performance computing environment.
  • SFP+ connectors: The four SFP+ connectors on the other end of the cable are used to connect the cable to SFP+ ports on servers, storage devices, or other networking equipment. Each SFP+ connector supports data transfer rates of up to 10 Gbps, which means that the cable can support a total of 40 Gbps of data transfer when all four SFP+ connectors are in use.

Benefits of Using with Passive Cable

The QSFP-4SFP10G-CU2M= Cisco 2M 40GBASE-CR4 QSFP+ Cable is a high-speed, low-latency cable that can provide several benefits to users, including:

  • High-speed data transfer: The QSFP-4SFP10G-CU2M= cable is designed to transfer data at high speeds of up to 40 Gbps, making it ideal for high-performance computing, data centers, and other applications that require high-speed data transfer.
  • Low power consumption: The QSFP-4SFP10G-CU2M= cable is designed to consume very little power, making it an energy-efficient solution for data centers and other applications that require high-speed data transfer.
  • Easy to use: The QSFP-4SFP10G-CU2M= cable is a plug-and-play solution that requires no additional software or drivers to be installed, making it easy to use and deploy in a variety of applications.
  • Cost-effective: The QSFP-4SFP10G-CU2M= cable is a cost-effective solution compared to other high-speed data transfer options, making it an attractive option for users who want high-speed data transfer without breaking the bank.
  • Reliable: The QSFP-4SFP10G-CU2M= cable is designed to be reliable and durable, with a rugged construction that can withstand the rigors of daily use in a variety of applications.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Cables - Direct Attach Cable

Direct Attach Cable, also known as the DAC cable, connects the equipment and peripherals in a data network. All the active networking equipment, including the data storage devices, switches, routers, servers, and more, will be connected and synched using the DAC cables. As far as the usage is concerned, these direct attached copper cables are getting fame in the data storage centers and the industry sector and server rooms: the reason being the cost-effective, efficient, and easier way to form the connection.

Direct Attach Copper Cables Are Terminated with Modules:

DAC cables are terminated from the manufacturer with the modules, which can easily connect the active peripheral equipment and secure an electrical connection. These modules are factory terminated and cannot be removed from the DAC cables afterward. Hence these wires possess a fixed length.

There are plenty of types and models available for the direct attach cables, including the direct, breakout, active and passive. As mentioned in the name, the direct cable can form a direct stable connection among the two peripherals, while breakout can connect one port with the four others. On the other hand, an active DAC cable will transmit signals to a little longer distance than the passive ones.

We, at ALLHDD, have got you all the range DAC cables for you to shop from! Choose from the following sub-categories: 0.5 Meter, 1 Meter, 16.4 Feet, 2 Meter, 4xC-13 Attached, 5 Meters, SFP+, 0.65 Meter, 10 Feet, 10 Meters, and 3 Meter.

DAC cables can follow longer paths:

Many of you might be wondering if the direct attach cable can transmit the data up to 10 meters or more! Yes, these cables can transfer the data to a more extended range depending on the data rate. The data rate is inversely proportional to the transmit range- the more the data rate, the less will be the range!

Direct Attach Data Cables are cost-effective!

DAC cables are more cost-effective as compared to the other ones. Using the two optical transceivers and fiber cable will not generate similar results as these DAC cables would!

Immense Reliability:

Not only are these cost-effective and can cover long range but are reliable as well! As already mentioned, the DAC cables are factory terminated with a module that plugs into the networking equipment and generates a physical connection. Apart from the secure connection, the 26 to 28 AWG Copper material makes them rugged. Therefore, surviving through the damage and cracks, DAC cables are a way to connect peripherals swiftly. You can choose from the following options 7 Meter, ProCurve, 0.65M, 1.2 Meter, 20 Meter and 30 Meter and also claim a 2.5% discount!
