What is difference between 100G, 400G and 800G optical modules?

What are 100G, 400G and 800G optical modules?

Optical modules play a crucial role in modern network communication infrastructure, seamlessly converting electrical signals into optical signals. Understanding their basic structure and operating principles is crucial for understanding their role in promoting high-speed data transmission.

100G optical module

100G optical module is an optical module with a speed of 100G. The commonly used package is QSFP28 [https://www.szrollball.com/100gbs-qsfp28-sr4-lr4-er4-optical-transceiver-module.html], which has 4 independent optical signal transmission and reception channels, with a transmission rate of 25G per channel.

400G optical module

400G optical module supports a transmission rate of 400Gbps, which is an extremely high data transmission rate that can meet the needs of large-scale data centers and high-performance computing. 400G optical modules typically use multiple interface types, including QSFP-DD (quad small pluggable dual density), OSFP (eight small pluggable), and so on. These interface types provide high-density port configurations and increased bandwidth.

800G optical module

800G optical module is a high-speed data transmission Q device that provides extremely high data transmission rates and can meet the rapidly growing demand for data traffic. Usually, 800G optical modules use new generation interface types to support higher bandwidth requirements and transmission rates. This may include emerging interface standards such as QSFP-DD and OSFP.

The difference between 100G, 400G, and 800G optical modules

Transmission distance:

100G optical modules typically support multi-mode fiber transmission distances up to 100m, and single-mode fiber transmission distances up to 100km. For 400G optical modules, the transmission distance of multimode fiber is limited to around 100m, while the transmission distance of single-mode fiber can be extended to tens of kilometers. Similarly, the 800G optical module is also adaptable to various transmission distances, including short distance multimode fiber (MMF) and long distance single-mode fiber (SMF), to meet different requirements

Application scenarios.

Power consumption and cost: With the increase of module speed, power consumption increases, and cost also increases. The 800G module has high transmission speed and high power consumption, requiring stronger heat dissipation and power supply system support.

Performance:

100G optical module is suitable for medium-sized data transmission needs and has stable performance. 400G optical module [https://www.szrollball.com/products/fiber-transceiver-modules/400g-qsfp-dd-dr4-optical-transceiver/] provides higher data transmission rates, suitable for large-scale data centers and high bandwidth demand scenarios. 800G optical module has the highest transmission rate and is suitable for scenarios with extremely high bandwidth requirements such as ultra large scale cloud computing and artificial intelligence.

Advantages and Applications of 800G Optical Modules

800G optical module has powerful performance, doubling network throughput and significantly improving data transmission speed and processing capabilities in data centers and cloud computing. In addition, it can also reduce costs and energy consumption, while improving network stability and reliability. This makes 800G optical modules a popular choice in the data center and cloud computing markets. With the development of the Internet of Things and the widespread application of 5G networks, the demand for high-speed and high-capacity networks is constantly increasing. This will further drive the market demand for 800G optical modules.
