Description

The SFP-H10GB-CU5M is a Cisco 10-Gigabit SFP+ direct-attach copper (DAC) cable, designed for high-speed, low-latency data transmission between networking devices over relatively short distances. It is commonly used for connecting Cisco switches, routers, and other network devices in environments where 10-Gigabit Ethernet connectivity is needed.

Key Features and Overview:

• Model: SFP-H10GB-CU5M

• Type: SFP+ Direct Attach Copper (DAC) Cable

• Data Rate: 10 Gbps

• Length: 5 meters (16.4 feet)

• Interface: SFP+ (Small Form-factor Pluggable Plus) to SFP+ connector

• Cable Type: Copper (Passive Copper Cable), often referred to as a DAC cable.

Key Specifications:

1. 10-Gigabit Speed:

   • The SFP-H10GB-CU5M supports 10 Gigabit Ethernet (10GbE) speeds, providing high-bandwidth connectivity between devices such as switches, servers, routers, and storage devices.

   • This speed is ideal for high-performance networks, including those used in data centers, high-frequency trading, cloud computing, and enterprise environments.

2. Direct Attach Copper (DAC):

   • DAC cables are cost-effective alternatives to fiber-optic cables for short-distance connections. They are made of copper wiring and come with SFP+ connectors at both ends.

   • The SFP-H10GB-CU5M is a passive DAC cable, meaning it doesn’t require an external power source for signal regeneration, making it simpler and more affordable for short-range 10GbE connections.

3. Length:

   • The 5-meter length of the cable is suitable for short-distance connections. This makes it ideal for rack-to-rack or server-to-switch connections in data centers, network closets, and server rooms, where devices are typically within a 5-meter range of each other.

4. Connector Type:

   • The cable has SFP+ connectors on both ends, meaning it’s compatible with SFP+ ports on Cisco switches, routers, servers, and other networking devices.

   • The SFP+ connectors are hot-swappable, which allows easy installation and removal of the cable without needing to power down the devices.

5. Passive Cable:

   • Being a passive copper cable, it does not contain any built-in signal boosters, which makes it more cost-effective compared to active DAC cables. However, passive DAC cables typically support shorter distances (up to 7 meters or so depending on the environment) before signal degradation occurs.

   • Passive cables are well-suited for short-range connections in controlled environments such as data centers and network cabinets.

Applications:

• Data Center Interconnects:

  • Ideal for connecting servers, storage devices, and network switches within data centers, the SFP-H10GB-CU5M enables fast, low-latency communication between devices, which is essential for high-performance data center operations.

• High-Performance Computing:

  • Used in environments where large amounts of data need to be transferred quickly and reliably between servers, such as in high-performance computing (HPC) clusters or cloud computing infrastructure.

• Network Topology:

  • It’s a great option for connecting devices within the same rack or network stack, particularly when you need low-latency connections that can handle high-volume data traffic.

• Ethernet Switch-to-Switch Connections:

  • Commonly used to connect Cisco Ethernet switches over short distances within a network closet, helping to build network backbones that require high throughput.

• Short-range Interconnects:

  • Perfect for interconnecting storage area networks (SAN), network-attached storage (NAS) devices, or connecting routers to switches.

Benefits:

1. Cost-Effective:

   • Since it uses copper wire rather than fiber, the SFP-H10GB-CU5M is often less expensive than fiber-optic alternatives, making it a good choice for short-distance 10GbE connectivity.

2. Simplicity and Ease of Use:

   • Plug-and-play functionality with SFP+ connectors makes installation quick and easy without requiring additional configuration or power sources.

3. High-Speed Data Transmission:

   • It provides 10Gbps data transfer rates, ensuring that your network can handle demanding workloads, such as large data transfers, high-definition video streaming, and real-time communications.

4. Reduced Latency:

   • The cable provides low-latency performance, making it ideal for applications like video conferencing, real-time data analytics, and enterprise applications that rely on quick data transmission.

5. Durability:

   • DAC cables are generally more durable than fiber cables, as they are less susceptible to physical damage, bending, and environmental conditions, making them suitable for environments with more movement.
