OEM and customized 40G QSFP+ AOC solutions are available for network equipment manufacturers, industrial system integrators, distributors, and large-scale infrastructure projects. Customization options may include cable length, fiber type, armored construction, connector labeling, product identification, packaging, branding, and other project-specific requirements.

For industrial or high-volume applications, compatibility can be evaluated with specific switches, servers, industrial Ethernet equipment, InfiniBand systems, and other networking platforms. Customers can provide equipment models, required transmission distance, operating environment, quantity, and cable-management requirements for a suitable configuration.

What makes this 40G QSFP+ AOC industrial-grade?

The industrial-grade version is designed to operate across a significantly wider temperature range than a typical commercial-grade cable. This model is specified for operation from -40°C to +85°C, making it more suitable for industrial equipment, outdoor-controlled environments, and networking systems exposed to substantial temperature variation.

What is the maximum transmission distance?

The cable supports up to 82m when used with OM2 multimode fiber and up to 300m with OM3 fiber. The appropriate fiber configuration should be selected according to the required link distance and the specifications of the connected equipment.

Why is an armored cable useful in industrial applications?

The armored construction provides additional mechanical protection for the internal optical fibers against handling, compression, routing stress, and other physical influences. This can improve the robustness of the cable assembly in demanding installation environments.

Does the AOC support both 40G Ethernet and InfiniBand?

Yes. The product is designed for 40G Ethernet as well as InfiniBand FDR/EDR applications. However, the actual operating protocol is determined by the connected host equipment and its supported interface configuration.

Does the cable require separate QSFP+ optical transceivers?

No. The optical transmitters and receivers are integrated into the QSFP+ cable ends. This makes the AOC a complete point-to-point optical connection that can be installed directly into compatible QSFP+ ports.

Why does the product use NRZ instead of PAM4?

The 40G QSFP+ architecture uses four parallel lanes at approximately 10Gbps per lane, making conventional NRZ signaling sufficient for the specified data rate. PAM4 becomes more relevant in higher-speed interfaces where greater bandwidth is required per physical lane.
