OEM and ODM customization is available for the 800G OSFP to QSFP-DD AOC to support specific equipment and deployment requirements. Custom options can include cable length, cable labeling, EEPROM configuration, optical and electrical identification information, packaging, and other assembly requirements.

The cable can be supplied in customer-specified lengths within the supported transmission range. Customized programming and identification can also be provided to improve compatibility with specific host platforms and network management systems.

Why use an OSFP-to-QSFP-DD AOC?

The cable enables direct optical connectivity between equipment using two different 800G pluggable form factors. This can be particularly useful when one network device uses OSFP ports while another uses QSFP-DD ports, allowing interoperability without deploying separate transceivers and fiber patch cables.

Why does the cable use 850nm VCSELs and OM3 fiber?

850nm VCSEL technology is widely used for high-speed short-reach multimode optical communication because it offers a practical combination of bandwidth, power efficiency, and cost. OM3 multimode fiber is suitable for short-distance data center applications and supports the required bandwidth for this 800G AOC.

What is the role of DSP in this AOC?

The integrated DSP processes and conditions the high-speed electrical and optical signals to help maintain signal integrity across the 106.25Gbps PAM4 lanes. This is particularly important for high-speed 800G transmission where signal quality becomes increasingly sensitive to loss and distortion.

Why is the maximum reach specified as 30 meters?

The 30m maximum reach is based on the specified optical architecture using 850nm VCSELs and OM3 multimode fiber. This makes the cable primarily suitable for short-reach data center and equipment interconnects rather than long-distance campus or telecommunications links.

What does the 14W power rating mean?

The specified ≤14W value represents the maximum power consumption of the active optical cable assembly under the stated operating conditions. This is an important consideration when calculating the power and thermal budget of high-density 800G switches and other networking equipment.

Does this AOC support DDM/DOM?

Yes. DDM/DOM functionality is supported, allowing compatible host equipment to obtain diagnostic and operating information from the cable assembly. This can assist with monitoring link conditions and maintaining high-density network infrastructure.
