## Summary description

The BlueOptics 9MJK9-BO is a 3 m InfiniBand fibre optic cable with QSFP connectors designed for high-speed data transmission. It features male-to-male connectors and an aqua color, ensuring compatibility with various networking equipment. Ideal for data centers and high-performance computing environments, this cable offers reliable connectivity and minimal signal loss.

## Long description

The BlueOptics 9MJK9-BO InfiniBand fibre optic cable 3 m QSFP Aqua is a 3‑metre active optical cable (AOC) with QSFP to QSFP male connectors and an aqua jacket. Designed for high‑speed short‑reach links, this cable supports multimode optical transmission and is compatible with systems that accept QSFP 40GBASE‑SR4 style connections. The pre‑assembled AOC integrates transceivers on both ends to transmit and receive optical signals without separate SFP/QSFP modules, providing a plug‑and‑play link for switches, routers and storage platforms.
Advantages
This BlueOptics AOC offers a compact, ready‑to‑use fibre connection that eliminates the need for separate transceiver modules and patchcord mating, reducing installation time and the risk of connector contamination. The integrated design and multimode QSFP interface enable simultaneous transmit and receive channels for aggregated 40 Gbit/s applications. Built to MSA‑compatible QSFP form‑factor practices, the cable provides consistent optical performance and reduced electromagnetic interference compared with copper alternatives.
Suitable for
Short‑reach 40 Gbit/s links between QSFP ports in data centres
Interconnects for switches, routers and storage arrays that accept QSFP AOCs
High‑performance computing clusters and server uplinks requiring low latency
Environments where a pre‑assembled, cleanable‑free fibre solution is preferred
Key specifications
Connector type: QSFP male to QSFP male (QSFP to QSFP)
Cable type: Active Optical Cable (AOC) with integrated transceivers
Length: 3 metres
Supported protocol: 40GBASE‑SR4 / InfiniBand‑class multimode optical transmission
Jacket colour: Aqua (multimode identification)
Typical applications: Ethernet, Fibre Channel over Ethernet, InfiniBand short‑reach links
How to use
Verify that both devices support QSFP AOC connections and the intended 40 Gbit/s protocol profile. Unpack the cable, remove any protective caps from the QSFP ends, and insert each QSFP connector firmly into the corresponding QSFP port until it latches. Confirm link LEDs or management interfaces indicate an active link and check device diagnostics for correct lane negotiation and signal parameters. For hot‑swap capable equipment, the cable can be inserted or removed while systems are powered, following the host hardware guidelines.
Usage recommendations
Route the 3 m cable with gentle bends and avoid tight kinks or strain on the connectors; maintain bend radii as recommended for multimode fiber AOCs. Ensure host hardware firmware supports third‑party AOCs if vendor lock‑in checks are implemented. Use device monitoring interfaces to read digital diagnostics if supported by the host for proactive maintenance.
