High-Speed Connectivity

The 1990-4657 HPE Aruba 10 Gigabit SFP+ LC LR 10KM SMF Transceiver provides high-speed connectivity for your network. Here are some key features that contribute to the module's high-speed connectivity:

  • 10 Gigabit Ethernet: The module supports 10 Gigabit Ethernet, which provides a high-speed data transfer rate of up to 10 Gbps. This makes it ideal for data-intensive applications, such as video streaming, cloud computing, and big data.
  • Low latency: The module is designed to minimize latency, which is the delay between sending and receiving data. This ensures that your network operates smoothly and efficiently, particularly for real-time applications, such as video conferencing and online gaming.
  • Efficient data transmission: The module supports advanced protocols, such as TCP/IP offloading and checksum offloading, which reduce the processing overhead of the network equipment. This results in more efficient data transmission and higher performance.
  • Jumbo frames: The module supports jumbo frames, which are larger than standard Ethernet frames. This reduces the overhead of the network equipment and enables faster data transfer.
  • Multi-mode and single-mode fiber support: The module supports both multi-mode and single-mode fiber, providing flexibility and versatility for a wide range of network environments. This allows you to use the module in a variety of settings, including data centers, campus networks, and remote sites.
Enhanced Performance

The 1990-4657 HPE Aruba 10 Gigabit SFP+ LC LR 10KM SMF Transceiver is designed to deliver enhanced performance for your network. Here are some key features that contribute to the module's high performance:

  • Advanced signal processing: The module uses advanced signal processing techniques, such as equalization and clock and data recovery, to ensure reliable and accurate data transmission. This helps to minimize errors and ensure that your network operates smoothly and efficiently.
  • Error correction: The module supports advanced error correction techniques, such as forward error correction (FEC), which can detect and correct errors in the data stream. This helps to ensure that your data is transmitted accurately and reliably.
  • Low power consumption: The module is designed to consume low power, which helps to reduce energy costs and environmental impact. This is achieved through the use of advanced technologies, such as low-power laser drivers and power management features.
  • Hot-swappable: The module is hot-swappable, which means that it can be inserted or removed from a network device while the device is operating. This minimizes downtime and makes it easy to install or replace the module.
  • Quality of Service (QoS): The module supports QoS, which enables you to prioritize certain types of traffic, such as voice or video, over other types of traffic. This ensures that critical applications receive the necessary bandwidth and resources for optimal performance.
Digital Optical Monitoring (DOM)

The 1990-4657 HPE Aruba 10 Gigabit SFP+ LC LR 10KM SMF Transceiver supports Digital Optical Monitoring (DOM) technology, which enables you to monitor the optical parameters of the module in real-time. Here are some key features of DOM and how they can benefit your network:

  • Real-time monitoring: With DOM, you can monitor the optical power, temperature, and other parameters of the module in real-time. This enables you to detect potential problems, such as a high temperature or low power, before they cause performance issues or downtime.
  • Enhanced troubleshooting: DOM provides detailed diagnostic information about the module, which can help you troubleshoot problems and optimize network performance. This can be particularly useful for identifying issues with the fiber optic cabling or other components of the network.
  • Customizable alerts: The DOM feature allows you to set up customizable alerts for different optical parameters. For example, you can set up an alert if the optical power drops below a certain level. This enables you to proactively address potential issues before they become major problems.
  • Simplified maintenance: DOM can help simplify maintenance by providing detailed information about the module's performance and health. This can help you identify potential problems and plan maintenance activities more efficiently.
