Benefits of 800g Optical Transceivers in Data Centers

Transceivers can change an entire infrastructure of a modern optical data center. To the resources available, they have a high data rate throughput of 800 gigabits. This is an increase in performance, efficiency, and scaling. This is needed and expected given the rapid progression of technology we are currently facing as an entire civilization. Hence, eyeing up a high-performance computing system or any other kind of consumer or industrial solution requires entire optimization on all ends.

Alas, the shifts from one technology to another require optimization on another level as well and can become a headache.

Understanding 800g QSFP-DD AOC and Direct Attach Cables

Choosing Between Active Optical Cable and DAC

When it comes to the comparison of active optical cables (AOCs) and direct attach cables (DACs), other technical aspects and performance parameters should be considered. A torrent of insights reveals that active optical cables can be used for longer sustainment owing to their ability to integrate photonically, which makes them less susceptible to electromagnetic interference. This implies that AOCs would be useful in large data and fleet deployment where long connection between devices is an intrinsic characteristic of the task. Moreover, this type of interconnection allows for devices being interconnected to be light and fluffy, owing to optical fibers being light in weight. 

On the other hand, the direct attach cable, which is composed of copper as opposed to AOC and TAA and is applied in a short range of 10 meters using low DAC, is more effective and less costly. Integrated copper interconnect cables (DACs), have a larger energy consuming capacity in their active components, thus, they are more power dense and therefore cost effective since the wires designed for DACs are usually designed to only operate over short distances away from the source. Moreover, the active dielectric coupler behaved a lot better in a fixed placement, where the demand was for a high data rate for short-reach applications or connections within the server racks and adjacent switches.

When deciding between the two, considerations such as the distance required, interference possibilities, power usage, and budget must be considered. As AOCs and DACs support different parameters of use while enhancing the efficiency of the networks, they also play important roles within the network systems.

How 800g QSFP-DD AOC Ensures Optimal Connectivity

800G QSFP-DD Active Optical Cables (AOCs) offer a very effective solution considering that the big challenge for contemporary scenarios of data centers is no longer how to increase the amount of data but rather how to transfer large amounts of information over long distances using optics. These AOCs are capable of delivering up to 800 Gbps data rate, which fits high bandwidth requirements and new-age network designs. The poor voluminosity offered by the optical fiber cables in 800G QSFP-DD solutions, in addition to management issues, improves both the latency and the energy consumption compared to the regular copper offering. It improves overall performance and energy efficiency. In addition, due to the ingenious design of the QSFP-DD connectors, permanent interconnections capable of withstanding high-density interconnections are created, which are necessary for data integrity and system reliability.
