OEM and customized 200G QSFP56 to 4×50G SFP56 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 deployments, compatibility can be evaluated against specific QSFP56 and SFP56 switches, servers, NICs, and other networking equipment. Customers can provide equipment models, required transmission distance, cable length, operating environment, quantity, and application requirements for configuration and compatibility assessment.

What does the 200G to 4×50G breakout configuration accomplish?

The cable converts one 200G QSFP56 port into four independent 50G SFP56 connections. This allows a 200G network port to communicate with multiple 50G interfaces and can help increase port utilization during network expansion or migration.

How is the 200G bandwidth distributed across the cable?

The QSFP56 side uses four optical channels in each direction, with each lane supporting up to 53.125Gbps. This provides an aggregate data rate of up to 212.5Gbps, while the four SFP56 ends provide individual 50G-class connections.

What is the maximum reach of this AOC?

The specified maximum transmission distance is 70m over OM3 multimode fiber. This range makes the cable suitable for short-distance connections within data center racks and between nearby racks.

Why is CDR used in this cable?

The integrated Clock and Data Recovery circuitry helps recover signal timing and regenerate high-speed signals. This supports stable transmission and improved signal integrity at the high data rates used by QSFP56 and SFP56 interfaces.

Can all four SFP56 ends connect to separate network devices?

Yes. The breakout ends are designed as independent SFP56 interfaces and can be connected to compatible 50G network ports. The actual breakout operation depends on the configuration and capabilities of the connected QSFP56 host equipment.

What is the benefit of the armored cable construction?

The armored construction provides additional mechanical protection for the internal optical fibers during installation, routing, and maintenance. It is particularly useful in high-density environments where cable assemblies may experience frequent handling or mechanical stress.
