Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-3M-MA-BO 3 m QSFP28 macho/macho

The BlueOptics Q28-AOC-3M-MA-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed interconnects in data centers and high-performance computing environments. With QSFP28 male connectors on both ends, this cable supports high bandwidth links between compatible QSFP28 ports, offering low latency and reliable signal integrity over a short to medium distance. It is suitable for connecting switches, servers, storage systems and network cards that require 100GbE or InfiniBand connectivity.

Advantages

This active optical cable delivers high data throughput while reducing electromagnetic interference compared to copper alternatives, and its optical design enables stable operation at elevated speeds with lower power consumption at the transceiver level. The fixed 3 m length simplifies rack planning and avoids excess cable slack. QSFP28 male-to-male termination ensures straightforward, tool-free connections to compatible QSFP28 ports and maintains compliance with common QSFP28 form-factor expectations.

Suitable for

• High-performance computing clusters and InfiniBand interconnects
• 100 Gigabit Ethernet links between switches and servers
• Top-of-rack and end-of-row connections in data centers
• Connections between network interface cards (NICs) and storage systems

Key specifications

How to use

Install the BlueOptics QSFP28 AOC by aligning each QSFP28 male connector with the corresponding QSFP28 port on your devices and inserting until the connector latches. Ensure both devices are powered down or that hot-plug procedures are supported by your hardware before insertion to avoid port negotiation issues. After connection, verify link status through the device management interface or indicator LEDs and configure port settings for the required protocol and speed. For disconnection, release the latch and withdraw the connector straight out to prevent damage.

Recommendations

Use this 3 m QSFP28 AOC in cabling runs that require predictable signal integrity and minimal electromagnetic interference. Avoid tight bends and excessive pulling force on the cable; maintain the manufacturer’s minimum bend radius. Route the cable to prevent mechanical stress at the connector ends and keep it away from heat sources. Confirm compatibility with the QSFP28 ports and firmware policies of your equipment to ensure full operational performance.
