OEM and customized 200G QSFP-DD to 4×50G SFP-DD AOC solutions are available for network equipment manufacturers, system integrators, distributors, and data center operators. Customization options may include cable length, fiber type, armored construction, connector labeling, product identification, packaging, branding, and other project-specific requirements.

For volume projects, compatibility can be evaluated with specific QSFP-DD and SFP-DD switches, servers, NICs, and other networking equipment. Customers can provide equipment models, required transmission distance, fiber type, operating environment, cable length, and quantity for configuration and compatibility assessment.

What is the purpose of the 4×50G breakout configuration?

The cable converts a single 200G QSFP-DD connection into four independent 50G SFP-DD connections. This allows a high-bandwidth 200G switch port to connect directly to multiple 50G interfaces without deploying four separate optical transceiver pairs and additional patch cables.

How many optical lanes does the cable use?

The cable uses eight optical lanes in each direction. Each lane supports up to 25.78125Gbps, providing the bandwidth required for the 200G-class QSFP-DD connection and the four 50G breakout interfaces.

What is the maximum supported transmission distance?

The specified maximum reach is 70m over OM3 multimode fiber. This makes the cable particularly suitable for in-rack, row-level, and adjacent-rack data center connections.

Why is CDR included in this AOC?

Clock and Data Recovery circuitry helps recover timing information and regenerate high-speed signals at the cable ends. This helps maintain signal quality and timing performance across the optical link, particularly in high-density deployments.

Can this AOC be used with four independent 50G devices?

Yes, provided that the connected devices support compatible SFP-DD interfaces and the appropriate 50G operating mode. The breakout architecture allows the four SFP-DD ends to establish independent 50G connections.

What advantage does the armored version provide?

The armored construction offers additional mechanical protection for the internal optical fibers during installation, routing, and maintenance. It is especially useful in dense data center environments where cables may be exposed to repeated handling or mechanical stress.
