OEM and customized 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, labeling, connector identification, packaging, branding, and other project-specific requirements.

For volume deployments, compatibility can be evaluated with specific switches, servers, NICs, storage platforms, and InfiniBand systems. Customers can provide equipment models, required transmission distance, quantity, and application requirements for configuration and compatibility assessment.

Why does this 50G AOC use PAM4 modulation?

PAM4 allows two bits of information to be carried per symbol, enabling higher data rates over the optical channel without requiring a proportional increase in the number of physical lanes. The SFP56 interface uses this technology to support 50G-class Ethernet transmission.

What is the role of the integrated CDR?

The integrated Clock and Data Recovery (CDR) circuitry helps recover the timing of the incoming data and regenerate cleaner electrical signals. This is particularly useful for maintaining signal quality at high data rates and helps compensate for signal degradation introduced by the host interface and cable assembly.

What is the maximum transmission distance?

The specified maximum reach is 70m using OM3 multimode fiber. This makes the cable suitable for connections within a rack, between adjacent racks, and other short- to medium-distance data center links.

Why use an AOC instead of a separate SFP56 transceiver and fiber cable?

An AOC integrates the optical components and fiber cable into a factory-terminated assembly. This simplifies installation, reduces the number of individual components, and can provide a more economical solution for fixed point-to-point connections.

What advantage does the armored construction provide?

The armored structure provides additional protection to the internal optical cable against mechanical stress during installation, routing, and maintenance. It can be beneficial in dense data center environments where cables are frequently handled or routed through constrained spaces.

Is the cable compatible with all SFP56 equipment?

The cable follows the SFP56 form factor and relevant interface standards, but actual interoperability depends on the host equipment and supported protocol. The connected switches, servers, NICs, or other devices should support the required 50G operating mode and IEEE 802.3cd or compatible implementation.
