The coherent optical module is crucial in facilitating the optical networks’ performance by increasing the networks’ flexibility and capacity. This is achieved through better spectral efficiency, where more information can be sent within the available bandwidth without installing extra fiber. The module can also be dynamically reconfigured, which allows the network operators to modify the data rates and the channel spacing according to requirements and, hence, make efficient use of the network resources. In addition, owing to its accurate performance and advanced error correction techniques, the modular guarantees how fast communication links can be accessed even under long-distance conditions, essential for modern-day, high-capacity/efficient optical networks.

Thanks to its scalable architecture, it allows existing systems to integrate effortlessly, thus paving the way for future innovations without compromising the current state of the technology.

How Does the Acacia QSFP-DD Coherent Module Compare to Other Modules?

Differences Between Pluggable Optical Transceivers

The variants of Pluggable optical transceivers are pretty distinct in form factor, data rate, and reach – all of which significantly impact scaling the network and optimizing its performance. Basic models include SFP, QSFP, and QSFP-DD, which are widely used by today’s most sought-after transceivers. Smaller SFP transceivers have a data rate reaching up to 4.25 Gbps, which meets the low-end and short-HA applications in the data center. In contrast, the coherent pluggables feature even better performance. However, QSFP transceivers are more capacity-oriented than the latter, with rates between 10 Gbps and 100 Gbps capabilities, and are mainly deployed on 40G and 100G cables with mid-reach range. On the other hand, the latest generation of QSFP-DD transceivers offers a plethora of ultra-high data rates of up to 400 Gbps for the recent fiber networks, which are constantly required to handle a tremendous amount of data traffic with long-distance reach. These differences allow network operators to select transceivers to be deployed under specific scenarios governed by the cost and performance versus future requirements.

Comparison with Acacia 400G-OSFP-ZR Module

The Acacia 400G-OSFP-ZR module and QSFP-DD coherent module have been developed with the same target markets in mind. However, whereas the ZR module is intended for long-distance use, the OSFP ZR module offers further options for 400G Ethernet transport systems over a distance of up to 120 kilometers without any requirements for optical amplification and thus is capable of supporting data center interconnect DCI applications. At the same time, the QSFP-DD module also provides similar data rates but with lower peak power consumption and high port density with short to medium reach distance in a data center environment. Considering the physical design, it appears that the newer design of the QSFP-DD, which is more focused on the tamper-proof and compact internal deployment for cables, differs from ASB-plastic front panel elastomer surround with OSFP-ZR line card aimed at density and power. Therefore, the two modules’ applications will be guided mainly by network design requirements such as reachability, power consumption, and compatibility with the equipment, whereas structural size limits.
