Customer Questions & Answers
-
Question:
What is a 100G QSFP28 DAC Cable?
Answer: The 100G QSFP28 DAC Cable is a high-speed data transmission cable designed for short distances. It enables the transfer of data at a rate of 100 Gbps, making it ideal for connecting devices in data centers or for high-performance computing environments. These cables are typically used for connecting switches, servers, and storage systems, offering a reliable connection with low latency. Their passive design means no external power is required, simplifying installation. -
Question:
What are the advantages of using Passive Direct Attach Copper cables?
Answer: Passive Direct Attach Copper cables, like the 100G QSFP28 DAC Cable, provide several advantages over other types of connections. They are cost-effective, consume less power, and are lighter than their active counterparts. Additionally, their short length makes them ideal for short-distance applications, ensuring minimal signal loss. These cables are particularly beneficial for use in densely packed server racks where space is a premium. -
Question:
Is the 100G QSFP28 DAC Cable compatible with Cisco equipment?
Answer: Yes, the 100G QSFP28 DAC Cable is designed for compatibility with Cisco equipment and specifically fits the QSFP-100G-CU1M model. Cisco’s compatibility ensures optimal performance and reliability, enabling seamless communication between devices. This specificity makes it a preferred choice for organizations using Cisco networking solutions, which often require such high-speed connections for efficient data flow. -
Question:
What is the maximum distance that a 100G QSFP28 DAC Cable can support?
Answer: The maximum distance supported by a 100G QSFP28 DAC Cable is typically around 7 meters (approximately 23 feet) depending on the specific application and the devices used. For connections over short distances, such as those found in data centers or server rooms, these cables are ideal as they maintain high signal integrity and minimal latency. Users should evaluate their specific layout to determine the best length for their needs. -
Question:
Can I use a 100G QSFP28 DAC Cable for 25G or 40G Ethernet connections?
Answer: Yes, the 100G QSFP28 DAC Cable can be used for lower-speed applications, such as 25G and 40G Ethernet connections. While it is primarily designed for 100G connectivity, these cables maintain backwards compatibility. This feature is advantageous for scalability, as users can easily upgrade to 100G without needing to replace their cabling infrastructure. Always check compatibility with your network devices for optimal performance. -
Question:
What materials are used in the construction of 100G QSFP28 DAC Cables?
Answer: The 100G QSFP28 DAC Cable is typically constructed with high-quality copper conductors along with shielding materials to reduce electromagnetic interference. The connectors are designed for durability, offering robust connections that are resistant to wear and tear. This construction not only ensures reliable data transmission but also maximizes signal clarity, making it suitable for high-demand networking environments. -
Question:
What is the difference between QSFP28 and QSFP+ connectors?
Answer: The primary difference between QSFP28 and QSFP+ connectors lies in their data transmission capabilities. QSFP28 supports data rates of up to 100 Gbps, while QSFP+ is limited to 40 Gbps. The QSFP28's enhanced bandwidth is beneficial for applications requiring high-speed data transfer, such as data centers and large enterprise networks. Users should choose based on their current and future bandwidth needs. -
Question:
How do I install a 100G QSFP28 DAC Cable?
Answer: Installing a 100G QSFP28 DAC Cable is straightforward. Simply plug one end of the cable into the QSFP28 port of the transmitting device and the other end into the receiving device. Ensure that both devices are powered on and properly configured for data transmission. Its plug-and-play nature simplifies the installation process, making it an ideal choice for quick setups in network environments. -

10Gtek Network Transceivers Editorial Review
The DAC cable has garnered a largely positive reception from customers who appreciate its performance and compatibility across various networking setups. Users often highlight its effectiveness in connecting equipment such as Dell and Cisco switches, as well as its compatibility with Mellanox NICs. Several reviewers note that it serves as a great budget option specifically for home lab environments, underscoring its affordability without compromising on functionality. Users have praised the thin design of the cable, which allows for easier routing compared to thicker alternatives, notably genuine Cisco cables that can be cumbersome. Many have reported that the DAC performed as advertised, with successful connections and no significant issues encountered during operation. A few users do point out discrepancies with speed labels, such as a 40GB display when a 100G capability is expected, which denotes some inConsistency that could affect expectations for advanced users. On the support side, there was a mention of needing assistance, indicating that some customers may face challenges in their initial setups or configurations. However, overall feedback points toward a generally satisfying user experience, with many indicating they would purchase more units in the future. **
