Understanding 800G Optical Modules: Types, Applications, and Solutions by Optech

As the demand for faster data transmission continues to surge, 800G optical modules have gained widespread attention due to their high bandwidth, rapid transmission rates, excellent performance, high density, and future scalability. In this article, we will outline the various types of 800G optical modules and their applications, addressing some common questions to help you make an informed decision when selecting 800G optical modules.

Types of 800G Optical Modules

800G = 8x100G = 4x200G. Based on the single-channel rate, 800G optical modules can roughly be divided into two categories: 100G single-channel and 200G single-channel. The chart below illustrates the corresponding architectures. 100G single-channel modules are relatively easier to implement, while 200G modules require more advanced optical components and often necessitate a gearbox for conversion.

Single-Mode 800G Optical Modules

800G single-mode optical modules are suitable for long-distance fiber transmission and can cover a wider range of networks.

800G DR8, 800G PSM8, and 800G 2xDR4

These three standards share a similar internal architecture, all featuring 8 transmit and 8 receive channels, each with a 100Gbps single-channel rate, requiring a total of 16 optical fibers.

800G DR8 Optical Module

The 800G DR8 module uses 100G PAM4 and 8-channel single-mode parallel technology. This module uses single-mode optical fiber and offers a transmission distance of up to 500 meters. It is commonly applied in data centers for 800G-to-800G, 800G-to-400G, and 800G-to-100G interconnections.
For example, the FS 800G QSFP-DD DR8 provides excellent performance for 800G Ethernet applications. It offers up to 800Gbps throughput via eight pairs of single-mode fibers (SMF) with MPO-16 APC connectors, extending up to 500 meters. The module fully complies with IEEE P802.3ck, IEEE 802.3cu, and QSFP-DD MSA standards, ensuring seamless compatibility and reliable operation.

800G PSM8 Optical Module

The 800G PSM8 optical module uses CWDM (Coarse Wavelength Division Multiplexing) technology with 8 optical channels, each transmitting at 100Gbps, supporting a transmission distance of 100 meters. This module is ideal for long-distance transmission and fiber resource sharing, making it a great solution for high-density, high-throughput environments like data centers and telecom networks.

Applications of 800G Optical Modules

  1. Data Centers
    800G modules like DR8 and PSM8 are critical in facilitating high-speed interconnections within data centers, enabling multi-speed interconnects (e.g., 800G-to-100G, 800G-to-400G). They help maintain low latency and high throughput over long distances.

  2. Telecom Networks
    In the telecom sector, 800G modules are essential for expanding backbone network capacity while keeping energy consumption efficient. Modules like the 800G DR8 are widely used for 5G deployments, offering robust performance over extended distances.

  3. Cloud Networking and AI Infrastructure
    The high performance and scalability of 800G modules make them ideal for cloud service providers and AI infrastructure, where large amounts of data need to be processed at extremely high speeds.
