Technical Overview

This direct attach cable operates on the 10GBase-CU standard, which uses twinaxial copper cabling to achieve 10 Gbps data transfer rates over distances up to 7 meters. The passive design means no signal amplification or power consumption, resulting in lower latency and reduced heat generation compared to active optical cables.

The SFP+ connectors support hot-pluggable installation, allowing for maintenance and upgrades without network downtime. Each end features an integrated SFP+ transceiver that interfaces directly with SFP+ ports, eliminating the need for separate transceivers and fiber patch cables.

Key Product Advantages

This direct attach cable offers several advantages for network administrators seeking reliable 10GbE connectivity. The passive twinax construction provides a durable, flexible cable that resists bending and crushing in dense rack environments while maintaining signal integrity at 10 Gbps speeds.

Cost-Effective 10GbE Solution

Eliminates the need for separate SFP+ transceivers and fiber optic cabling, reducing both initial hardware costs and ongoing maintenance expenses compared to optical solutions.

  • No separate transceivers required
  • Lower total cost of ownership
  • Simplified inventory management

TAA Compliance for Regulated Procurement

Meets Trade Agreements Act requirements, making this cable suitable for government contracts, educational institutions, and other organizations with strict procurement regulations.

  • Government procurement compliant
  • Educational institution ready
  • Regulated industry suitable

Deployment / Use Cases

The AddOn 487649-B21-AO direct attach cable is ideal for connecting network switches to servers, storage arrays, or other switches within the same rack or adjacent enclosures. The 50cm length is particularly well-suited for top-of-rack switching configurations where minimal cable length reduces signal attenuation and improves airflow management.

Common deployment scenarios include connecting HPE ProCurve 2910al series switches to servers equipped with FlexFabric 10Gb 2-port 554FLR-SFP+ adapters, or linking Virtual Connect Flex Fabric 10Gb/24-Port modules in blade server environments. The cable also works with ProLiant ML310e Gen8 v2 servers and other MSA-compliant SFP+ ports.

Data Center Rack Connections

Connect switches to servers within the same rack for high-speed server-to-server communication or storage network access with minimal latency.

  • Top-of-rack switching
  • Server-to-server links
  • Storage network access

Network Aggregation Links

Establish short-distance connections between aggregation switches or between core and distribution switches in enterprise network designs.

  • Switch-to-switch connectivity
  • Distribution layer links
  • Network backbone connections

FAQ

What is the maximum data transfer speed of this SFP+ direct attach cable?

This cable supports 10 Gigabit Ethernet (10GbE) with a maximum data transfer rate of 10 Gbps using 10GBase-CU technology. The passive twinax design maintains this speed over the 50cm cable length without signal degradation, providing full 10GbE performance for short-reach connections between compatible network devices.

Is this cable compatible with HPE ProCurve 2910al series switches?

Yes, the AddOn 487649-B21-AO is specifically compatible with ProCurve 2910al/E2910al Series Switches including the 2910al-24G (J9145A), 2910al-24G-PoE+ (J9146A), 2910al-48G (J9147A), and 2910al-48G-PoE+ (J9148A) models. It also works with Virtual Connect Flex Fabric 10Gb/24-Port Modules, FlexFabric 10Gb 2-port 554FLR-SFP+ Adapters (629142-B21), and ProLiant ML310e Gen8 v2 servers.

What does TAA compliant mean for this networking cable?

TAA compliance indicates this direct attach cable meets the requirements of the Trade Agreements Act, which governs procurement for U.S. federal government agencies and certain other organizations. This makes the cable suitable for government contracts, educational institutions receiving federal funding, and other regulated procurement scenarios where TAA compliance is mandatory.

How does a passive twinax cable differ from an active optical cable?

Passive twinax cables like this AddOn 487649-B21-AO use copper conductors without signal amplification, resulting in lower power consumption, reduced heat generation, and typically lower cost compared to active optical cables. Active optical cables contain electronics that amplify signals, allowing longer reach but requiring power and generating more heat. Passive twinax is ideal for short distances up to 7 meters where simplicity and cost-effectiveness are priorities.

What is the warranty period for this SFP+ direct attach cable?

This cable comes with a 3-year limited warranty from the manufacturer. This warranty period provides assurance of product reliability and covers defects in materials or workmanship under normal use conditions, giving network administrators confidence in their infrastructure investment for medium-term deployment cycles.

Can this cable be hot-plugged during network operation?

Yes, the SFP+ connectors on this direct attach cable support hot-pluggable installation. This means you can insert or remove the cable from compatible SFP+ ports without powering down the network device, allowing for maintenance, upgrades, or reconfiguration without causing network downtime. Always follow proper electrostatic discharge precautions when handling any network components.
