OEM and customized 100G QSFP28 to 2×50G QSFP28 AOC solutions are available for network equipment manufacturers, system integrators, distributors, and data center operators. Customization options may include cable length, OM3 or OM4 fiber selection, connector labeling, product identification, packaging, branding, and other project-specific requirements.

For volume deployments, compatibility can be evaluated with specific switches, servers, NICs, and other 100G/50G networking equipment. Customers can provide equipment models, required transmission distance, fiber type, cable length, quantity, and application requirements for configuration and compatibility assessment.

How does the 100G to 2×50G breakout configuration work?

The cable connects one 100G QSFP28 interface to two independent 50G QSFP28 interfaces. The 100G side provides the aggregate bandwidth, while the breakout end divides the optical lanes into two 50G connections for compatible networking equipment.

What fiber should be used for the maximum 100m reach?

OM4 multimode fiber is recommended for the specified maximum reach of 100m. With OM3 fiber, the specified maximum distance is 70m. The actual link distance should also take the optical specifications of the connected equipment into account.

Does this cable require separate optical transceivers?

No. The active optical components are integrated into the cable assemblies, allowing the cable to be plugged directly into compatible QSFP28 ports. This reduces the number of separate transceivers and fiber patch cables required for the connection.

What is the advantage of using an active optical breakout cable?

An AOC provides optical transmission with integrated electronics and optics, making it suitable for longer distances and higher-density deployments than many passive copper alternatives. The integrated design also simplifies installation and cable management.

Can the two 50G connections be connected to different switches?

Yes, provided that the connected equipment supports the required 50G QSFP28 interface and breakout configuration. This allows a single 100G port to establish two independent 50G links, which can be useful for network expansion and port utilization.

Is the cable suitable for 100GBASE-SR applications?

Yes. The product is designed to support 100G-to-2×50GBASE-SR applications over multimode fiber. The connected networking equipment must support the appropriate 100G/50G breakout mode.
