An Overview of 200G QSFP-DD AOC

The Market Situation of AOC

Today’s hyperscale data centers and High-Performance Computing (HPC) markets require low-cost solutions for high-performance AOCs for the large-scale adoption of 200G and 400G data rates.

According to a recent report from LightCounting, the multi-mode AOC market will be experiencing significant growth over the next five years in the HPC and large-scale data center applications.

However, the market for 100G AOC is continually growing in the HPC and large-scale data center applications now, and it is still too early to adopt 400G AOC owing to cost and others so that the adoption of 200G AOC is expected to grow in the next years.

In the 200G AOC market, the 200G QSFP-DD AOC is a kind of parallel transceiver optics assembly. It will be the huge potential market and it is possible to replace copper technology in HPC and data center, the reasons include form factor, cost and so on. Next, we will explore them together.

Why Is 200G QSFP-DD AOC More Likely to Be Popular?

The 200G QSFP-DD AOC is a kind of 200G AOC that adopts the QSFP-DD form factor.

QSFP-DD is an eight-channel electrical interface with an additional row of contacts. It is being developed by the QSFP-DD MSA as a key part of the industry’s effort to enable high-speed solutions. The 200G QSFP-DD AOC meets the requirements of QSFP-DD MSA specification.

The QSFP-DD modules are similar to current QSFP. The systems designed with QSFP-DD modules can be backward compatible, allowing them to support existing QSFP modules and provide flexibility for end users and system designers. The 200G QSFP-DD AOC is convenient for end users and system designers.
