Design and Construction

The Cisco QSFP-4SFP25G-CU1M= 100G QSFP to 4x SFP 25G Passive Copper Splitter Cable is a high-speed, low-cost, and energy-efficient solution for connecting 100G switches and servers to 25G switches and servers. It is designed and constructed with the following key elements:

  • Cable Jacket: The outer layer of the cable is the cable jacket, which is made of a flame-retardant PVC material that meets industry safety standards. The cable jacket protects the internal wires and helps prevent electromagnetic interference (EMI) and radio frequency interference (RFI).
  • Copper Conductors: The QSFP-4SFP25G-CU1M= cable is a passive copper cable, meaning that it uses copper conductors to transmit electrical signals over the cable. Copper conductors are widely used in data center cabling because they are cost-effective and offer high-speed data transfer rates.
  • QSFP to 4x SFP Splitter: The QSFP-4SFP25G-CU1M= cable features a QSFP connector at one end and four SFP connectors at the other end. The splitter is a passive device that splits the 100G signal from the QSFP connector into four 25G signals that are transmitted over the SFP connectors.
  • EMI Shielding: The QSFP-4SFP25G-CU1M= cable is shielded to prevent electromagnetic interference (EMI) and radio frequency interference (RFI) from affecting the signal transmission. The shielding is achieved through the use of a conductive adhesive that covers the cable's outer surface.
  • Cable Length: The QSFP-4SFP25G-CU1M= cable is designed to be 1 meter in length, making it suitable for short-reach applications in data centers.

Environmental Considerations and Certifications

The Cisco QSFP-4SFP25G-CU1M= 100G QSFP to 4x SFP 25G Passive Copper Splitter Cable is designed to meet various environmental considerations and certifications. Here are some of them:

  • RoHS Compliance: The cable is RoHS compliant, which means it does not contain any hazardous materials such as lead, mercury, cadmium, and hexavalent chromium. This compliance ensures the cable is safe for the environment and human health.
  • REACH Compliance: The QSFP-4SFP25G-CU1M= cable is also REACH compliant, which means it meets the European Union's Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation. This compliance ensures that the cable does not contain any substances that are harmful to the environment or human health.
  • Operating Temperature: The cable is designed to operate within a temperature range of 0 to 70 degrees Celsius. This operating temperature range is suitable for most data center environments.
  • Operating Humidity: The QSFP-4SFP25G-CU1M= cable is designed to operate within a relative humidity range of 10% to 85%, non-condensing. This humidity range is suitable for most data center environments.
  • Safety Certifications: The QSFP-4SFP25G-CU1M= cable is certified by various safety organizations such as Underwriters Laboratories (UL), Canadian Standards Association (CSA), and Conformité Européenne (CE). These certifications ensure that the cable meets safety standards and is safe for use in data center environments.
  • Environmental Certifications: The cable is also certified by various environmental organizations such as ENERGY STAR and the US Environmental Protection Agency (EPA). These certifications ensure that the cable meets energy efficiency standards and does not harm the environment.

Advantages of Active Optical Cables

Active Optical Cables (AOCs) offer several advantages over passive copper cables, such as the Cisco QSFP-4SFP25G-CU1M= 100G QSFP to 4x SFP 25G Passive Copper Splitter Cable:

  • Longer Distance: AOCs can transmit signals over longer distances than passive copper cables, typically up to 100 meters, making them ideal for use in data center environments.
  • Higher Bandwidth: AOCs have higher bandwidth capabilities than passive copper cables, making them more suitable for high-performance computing applications and data center networks.
  • Lightweight and Flexible: AOCs are much lighter and more flexible than copper cables, making them easier to install and manage. They also have a smaller bend radius, which allows for more efficient cable routing and minimizes the risk of cable damage.
  • Better EMI/EMC Performance: AOCs have better electromagnetic interference (EMI) and electromagnetic compatibility (EMC) performance than copper cables, which can help to reduce signal interference and improve overall network performance.
  • More Secure: AOCs use light to transmit signals, which means they are more secure than copper cables, as they are not vulnerable to wiretapping or interference.
  • Future-Proof: AOCs support higher data rates and are compatible with newer technologies, making them more future-proof than copper cables. This can help to ensure that your network infrastructure is capable of handling future data demands.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

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!
