High-Speed Data Transmission
The Cisco SFP-H25G-CU2.5M is a 2.5-meter long 25GBASE-CU SFP28 cable that provides a high-speed and low-latency solution for data transmission over short distances. This cable is designed to support high-bandwidth applications such as data center networking, cloud computing, and high-performance computing.
The Cisco SFP-H25G-CU2.5M cable supports a data transmission rate of up to 25 Gbps, which makes it suitable for high-speed data transfer over short distances. This high-speed data transmission is achieved using the SFP28 electrical interface, which is designed to support data rates of up to 28 Gbps.
The cable uses copper conductors to transmit data, which provides a cost-effective and reliable solution for short-range data transmission. The passive copper design of the cable ensures low power consumption and eliminates the need for additional power supplies or cooling systems.
Moreover, the Cisco SFP-H25G-CU2.5M cable is designed to be hot-swappable, which means that it can be inserted or removed from a networking device without disrupting the operation of other devices in the network. This feature provides flexibility and allows for easy installation and maintenance of the network.
Installation and Configuration
The Cisco SFP-H25G-CU2.5M is a 2.5-meter 25GBASE-CU SFP28 cable that provides a high-speed, low-latency connection between networking devices. Here are the steps to install and configure this cable:
- Turn off the power to the networking devices that you will be connecting with the cable.
- Insert one end of the cable into the SFP28 port on the first networking device.
- Insert the other end of the cable into the SFP28 port on the second networking device.
- Power on the networking devices.
- Verify that the devices recognize the cable and establish a link between them. You can do this by checking the link status on each device's management interface or by using a command-line interface to check the link status.
- Configure the networking devices to use the cable for data transmission. Depending on the devices you are using, this may involve configuring port speed, duplex mode, VLAN settings, and other network parameters.
- Test the cable to ensure that it is providing the desired performance. You can use a network performance monitoring tool to measure bandwidth, latency, and other metrics.
It is important to follow the manufacturer's guidelines when installing and configuring the Cisco SFP-H25G-CU2.5M cable, as improper installation or configuration can result in performance issues or damage to the networking equipment. Additionally, make sure to handle the cable with care, as it can be sensitive to bending or twisting, which can damage the cable or affect its performance.
Cable Length and Distance Support
The Cisco SFP-H25G-CU2.5M is a 2.5-meter long 25GBASE-CU SFP28 cable that is designed for high-speed data transmission over short distances. The cable is designed to support a maximum distance of 2.5 meters, which means that it is suitable for use in data center environments where devices are located in close proximity to each other.
It is important to note that the maximum distance supported by the Cisco SFP-H25G-CU2.5M cable is dependent on several factors, including the quality of the cable, the quality of the connectors, and the quality of the networking devices that are being used. Therefore, it is recommended to follow the manufacturer's guidelines and best practices for installing and using the cable to ensure optimal performance and reliability.
In addition to the 2.5-meter length, the Cisco SFP-H25G-CU2.5M cable is also available in other lengths, including 1 meter, 3 meters, and 5 meters. The maximum distance supported by each cable length may vary, and it is important to consult the manufacturer's specifications to determine the maximum distance supported by each cable length.

About New Bulk Pack Products
Cables - Copper Cable
Coper cables still remain the most popular option in high voltage and low voltage applications such as networking. Despite the disadvantages, such as electromagnetic interference, copper still offers a cost-effective solution for many applications.
How does Copper Cable Transmit Data?
It is a simple process that starts by energizing one side of a copper wire to set electrons in it in motion. The electrons travel to the other end of the wire with the signal information. Since movement is involved, you can expect the electrons to lose their energy and eventually stop moving if the cable is very long. The loss of electron energy leads to a reduction in signal strength. When the electrons stop moving before reaching the other end of the copper wire, a total signal loss occurs. In long-distance data transmission, boosters are placed at an appropriate location to re-energize the electrons. That is usually not a problem of concern when wiring your server because of the short distance involved.
Does Length of Copper Cables Matter?
Yes, it does. As already mentioned, there is a degradation of signals as they move through the copper conductor due to losses. Copper wires have an internal resistance that will oppose the movement of current through them. Data moves through these copper cables as a stream of or pulses of current. The longer the wire, the higher the resistance and more likely signal strength deterioration. Think of it as walking uphill. The further you go, the more tired you become, and you may eventually stop moving.
When you are shopping for copper cables, just make sure you get an appropriate wire length for the application. Do not use a 10-meter cable where you can use a 5-meter cable. You make your system more efficient by using the best cable for the application.
Copper Cables for Every Application
You might have been made to believe that all copper cables are the same. That is not true. Manufacturers of these cables do so with specific applications in mind. A different approach is followed for applications where data rate and bandwidth are a priority. That is why you will find InfiniBand copper cables intended for such applications. Also, the connectors at the end of the copper wires show the intended use. You will find a big difference in the connectors used by IBM's RIO-2 copper cable and HP's X240 direct attach cable.When you are shopping for a copper cable, know what you intend to use it for. If you are not sure, consult with the sales representatives for any help. At ALLHDD, we have a technical team to help you solve any mystery in cable selection.
