BlueOptics QSFP28 100G optical direct attach cable, model 834972-B22, 5 m length

BlueOptics QSFP28 100G optical direct attach cable, 5 m length, provides a fixed optical link for short-reach 100 Gigabit Ethernet connections between compatible QSFP28 ports. Designed for data centre and rack environments, this direct attach cable simplifies cabling for switch-to-switch or switch-to-server interconnects while delivering low latency and consistent signal quality over a 5 metre span.

Advantages

The cable offers a compact QSFP28 form factor that supports 100G throughput with optical transmission characteristics optimized for short-distance interconnects. Its pre-terminated design removes the need for separate transceivers, reducing installation time and minimizing additional component requirements. The solution is intended to provide consistent signal integrity and lower power consumption compared with discrete transceiver-plus-fibre assemblies in equivalent short links.

Suitable for

• High-speed switch-to-switch connections in data centre racks
• Switch-to-server uplinks where 100 Gigabit ports are available
• Top-of-rack and aggregation layer interconnects with short cable runs
• Environments requiring fixed, low-latency optical links for network backbones

Key specifications

• Interface: QSFP28 optical direct attach
• Nominal speed: 100 Gigabit Ethernet
• Length: 5 metres
• Cable type: optical direct attach (pre-terminated)
• Typical application: short-reach data centre interconnects
• Latency: low, suitable for high-performance networking

How to use

Install the BlueOptics QSFP28 100G optical direct attach cable by inserting each QSFP28 connector into the appropriate device port until the latch engages. Ensure both ends are connected to compatible QSFP28 ports on networking equipment that supports 100G optical direct attach links. Verify link status and speed in the device management interface and route or configure interfaces as required by your network design. For optimal performance, avoid tight bends and keep the cable free from sharp kinks or mechanical stress.

Usage recommendations

Handle the cable by the connector housings and maintain minimum bend radius as specified by standard optical cable practice. Use in environments within the operating temperature and humidity ranges supported by your networking devices. Confirm compatibility with host equipment QSFP28 ports before deployment and perform link tests after installation to ensure proper operation.
