BlueOptics QSFP AOC cable AFBR-7QER15Z-CS1 40GBASE-SR4 15m for Ethernet/Infiniband

The BlueOptics QSFP AOC cable AFBR-7QER15Z-CS1 is a direct-attach active optical cable designed for short-reach 40GBASE-SR4 links. With a QSFP form-factor connector and a 15 m multimode fiber assembly, this AOC supports high-speed Ethernet and InfiniBand interconnects between switches, servers and storage equipment in data centers and network racks. The cable is intended as a vendor-compatible replacement for QSFP ports and provides optical signaling suited to four-lane 40 Gbit/s operation.

Advantages

This active optical cable offers low-latency, high-bandwidth connectivity over multimode fiber with reduced electromagnetic interference compared with copper solutions. The integrated active components enable reliable signal conditioning and equalization across the 15 m reach, while the QSFP connector ensures compatibility with standard QSFP ports used in modern data center switches and host adapters. The cable's compact assembly simplifies cable management in dense rack environments.

Suitable for

• 40G Ethernet links between top-of-rack and aggregation switches
• High-performance InfiniBand connections in compute clusters
• Short-reach server-to-switch and storage interconnects within data centers
• Environments requiring vendor-compatible QSFP optical attachments

When it may not be suitable

This active optical cable is designed for short-reach multimode links and is not intended for long-haul or single-mode fiber applications. It is not suitable where direct copper connections are required for power-over-cable or very low-cost short patching, nor for environments that mandate specific manufacturer-branded optics with vendor-locked compatibility checks.

Key specifications

• Form factor: QSFP (quad small form-factor pluggable)
• Data rate: 40 Gbit/s (4 lanes, SR4)
• Medium: active optical cable over multimode fiber
• Length: 15 metres
• Typical use: short-reach data center interconnects

How to use

Insert each QSFP connector into the corresponding QSFP port on networking equipment, ensuring the retention latch engages. Handle the cable by the connector housings and avoid tight bends in the fiber assembly to preserve signal performance. After insertion, verify link status and speed on connected devices and confirm proper lane mapping for 40GBASE-SR4 operation. For removal, disengage the latch and pull the connector straight out without twisting.

What to consider before purchase

• Confirm that your switches, adapters or transceivers support QSFP AOC modules and 40GBASE-SR4 signaling
• Verify port compatibility and physical QSFP slot access in your rack layout
• Check that a 15 m multimode reach matches the distance and cable routing in your environment

Usage recommendations

Use this QSFP AOC for short-reach, high-bandwidth links where multimode fiber is available and vendor-compatible optical attachments are acceptable. Maintain gentle bend radii, secure cable runs in racks to avoid strain on connectors, and test link integrity after installation to ensure full 40 Gbit/s operation.
