Frequently asked questions

• Q: What does 10GBASE-T mean for my network?
  A: 10GBASE-T refers to 10 gigabits per second Ethernet connectivity over copper twisted-pair cabling (RJ45). It enables high-speed networking over Cat6/Cat5e cables with relatively long distance support (up to 30 meters for copper solutions like this SFP+ module) and is commonly used to upgrade servers, storage, and switches without replacing fiber infrastructure.
• Q: Is this module compatible with HP/HPE switches?
  A: Yes. It is designed as a compatible SFP+ copper module for HPE networks and the HP 813874-B21 ecosystem, offering seamless integration with supported HP switches that accept SFP+ ports. Always verify specific device compatibility and firmware requirements with your vendor, but this module is intended for HPE environments.
• Q: Can I use Cat5e cables with this module?
  A: You can use Cat5e, but to achieve the full 10 Gbps performance, Cat6 is recommended. Cat5e may limit the maximum achievable distance or data rate under certain conditions, so opting for Cat6 ensures more reliable 10GBASE-T operation over longer runs up to 30 meters.
• Q: Is the module hot-swappable?
  A: Yes. SFP+ modules are typically hot-swappable, meaning you can insert or replace the transceiver without powering down the entire system, provided your equipment supports hot-swapping and maintenance procedures are followed.
• Q: What are the practical benefits of upgrading to this 10GBASE-T SFP+ module?
  A: Upgrading to a 10GBASE-T copper SFP+ module enables higher bandwidth between switches and servers using familiar RJ45 copper cabling, reducing latency and improving throughput for data-intensive applications. It also offers a cost-effective upgrade path by leveraging existing copper cabling and network infrastructure, which can lower total cost of ownership compared to fiber-based 10G solutions in certain deployments.
