100G QSFP28: A Shining Star in High-Speed Optical Communications

In today's era of digital information explosion, data traffic is experiencing unprecedented growth. From the widespread adoption of 5G networks to the booming development of emerging technologies such as cloud computing, big data, and artificial intelligence, the demand for high-speed and efficient data transmission is becoming increasingly urgent. Against this backdrop, 100G QSFP28, as a key technology product in the optical communications field, is playing a vital role, becoming a key engine driving the rapid development of the information age.

I. Technical Analysis of 100G QSFP28
(I) Advanced Packaging Technology
QSFP28, or Quad Small Form-factor Pluggable (QSFP28), is compact yet powerful. This package allows for hot-swappable modules while the device is operating, greatly facilitating maintenance and upgrades. Furthermore, the QSFP28 package can integrate multiple channels within a limited space, enabling high-density data transmission and meeting the demands of space-critical applications such as data centers.​

(II) High-Speed Data Transmission Capability

100G QSFP28 modules are capable of achieving data transmission rates of up to 100Gbps, thanks to their advanced signal modulation and processing technologies. For example, some 100G QSFP28 modules utilize four-level pulse amplitude modulation (PAM4) technology. Compared to traditional non-return-to-zero (NRZ) modulation technology, PAM4 can carry two bits of information per symbol, doubling the transmission rate within the same bandwidth, effectively addressing the challenges of growing data traffic.

(III) Excellent Optical Performance

Optically, 100G QSFP28 modules are equipped with high-performance optical transmitting and receiving components. These components include high-performance vertical-cavity surface-emitting lasers (VCSELs) for optical signal transmission and highly sensitive photodetectors for optical signal reception. These optical components not only ensure stable transmission and accurate reception of optical signals, but also minimize signal loss during transmission, thereby enabling long-distance, high-quality data transmission.

II. Application Scenarios of 100G QSFP28
(I) Core Hubs in Data Centers
In data centers, massive amounts of data need to be exchanged at high speeds between servers, between servers and storage devices, and between data centers and external networks. With its high speed and high density, the 100G QSFP28 optical module has become the preferred solution for internal data center network connections and Data Center Interconnect (DCI). It can quickly process the large amounts of data generated by applications such as cloud computing and big data analytics, ensuring efficient data center operations.

(II) Key Support for 5G Communication Networks
With the large-scale deployment of 5G networks, the fronthaul, midhaul, and backhaul networks between base stations have placed extremely high demands on data transmission speed and capacity. In 5G communication networks, 100G QSFP28 optical modules enable high-speed data transmission between base stations and between base stations and the core network, ensuring the full utilization of the low latency, high bandwidth, and wide connectivity characteristics of 5G networks, providing users with higher-quality 5G communication services. (III) A Powerful Weapon for Enterprise Network Upgrades
For enterprises, with the deepening of digital office work and the continuous expansion of business, performance requirements for internal networks are increasing. 100G QSFP28 optical modules can be used to upgrade enterprise core networks, improve internal data transmission speeds, accelerate office automation processes, and enhance operational efficiency. They can also ensure fast and stable data transmission when enterprises interact with external partners.
