Product information

Description

The LevelOne AOC-0503 is a high-performance QSFP28 fiber optic network transceiver module engineered for high-speed data transmission reaching up to 100 Gbps. Designed to meet the rigorous demands of modern enterprise and data center environments, this module utilizes advanced Chip on Board (COB) technology to ensure reliable and efficient optical communication. It serves as a robust solution for upgrading network infrastructure where high bandwidth and low latency are critical requirements.

Advantages

This transceiver module offers exceptional performance for I/O-intensive applications, providing four distinct channels that support a combined bandwidth of 100 Gbps. Its design prioritizes system flexibility and operational efficiency, allowing network planners to integrate high-speed connectivity seamlessly. The inclusion of Digital Diagnostics Monitoring (DDM) allows administrators to track the status of the connection in real-time, while the hot-swappable capability ensures that maintenance can be performed without interrupting network services.

Suitable for

  • High-speed data center interconnects
  • Enterprise-grade network infrastructure
  • I/O-intensive server environments
  • 100G Ethernet networking upgrades

This module may not be suitable for long-distance telecommunications infrastructure, as it is optimized for shorter-range high-speed data transmission. It is also not compatible with hardware interfaces other than the QSFP28 standard, meaning it cannot be used in older SFP or SFP+ ports without appropriate conversion hardware.

Key specifications

  • Data transfer rate: Up to 100 Gbps
  • Interface type: QSFP28
  • Wavelength: 850 nm
  • Networking standards: IEEE 802.3bm and 100GBASE-SR4
  • Weight: 0.117 kg
  • Color: Silver and Aqua

To use the LevelOne AOC-0503, ensure that your network switch or server interface is compatible with the QSFP28 standard. Simply insert the module into the designated port on your networking equipment. Because the device is hot-swappable, it can be installed while the system is powered on, though it is recommended to follow your specific hardware manufacturer's guidelines for port configuration to ensure optimal link establishment.

What to consider before purchase

  • Verify that your networking hardware supports the QSFP28 interface.
  • Confirm that your infrastructure requires 850 nm wavelength fiber optic connectivity.
  • Check the physical space requirements for the cable length to ensure it meets your rack or server room layout.
Usage recommendations: For optimal performance and longevity, ensure that the fiber optic connectors are kept clean and free of dust before installation. Avoid bending the cable beyond its recommended radius to maintain signal integrity.
