SFP (Small Form Factor Pluggable) is a compact, hot-swappable transceiver module that converts electrical signals into optical signals (and vice versa), enabling long-distance communication between devices. One of the main advantages of SFP modules is their hot-swappable nature, which allows them to be inserted or removed without powering down network devices.
A cable is a cable assembly with fixed connectors at both ends. The connectors used are the same as the interfaces of optical modules, but compared to optical modules, high-speed cables do not need to be matched with jumpers. The connectors of DAC do not have expensive optical lasers, which greatly saves costs and power consumption, and becomes a low-cost and high-efficiency high-speed data communication solution to replace optical modules.
Optical module interfaces include fiber optic interfaces and RJ45 interfaces. Fiber optic interfaces are generally used to connect fiber optic patch cords with connectors such as LC, SC, MPO, etc. Optical modules with this type of interface are usually called optical port modules; while RJ45 interfaces, as the name implies, are used to connect network cables. We generally call optical modules with this type of interface electrical port modules.
The availability of data centers and the speed of cloud services make the shift to serverless infrastructure possible. Data centers are truly changing business infrastructure. The following global statistics reveal the growth trend in terms of geographic location and eco-social aspects. As of 2021, there are about 8,000 physical data centers in the world. 2. Global major data center distribution areas.
Router: A computer network device that forwards the received data packets according to the destination IP address and selects the appropriate transmission path until it is forwarded to the destination. This process is called routing.
In the era of artificial intelligence, 5G and cloud computing, the demand for network bandwidth is growing exponentially. The desire for high-speed transmission in data centers and enterprise backbone networks has pushed optical module technology to continuously break through the limits.
I. What is 400G QSFP-DD DR4 Silicon Photonic Module?1.1 Basic Definition of 400G QSFP-DD DR4 Silicon Photonic Module400G QSFP-DD DR4 Silicon Photonic Module uses silicon photonic integration technology and has a transmission rate of up to 400Gbps.
As the core component of optical communication system, the performance of optical module is directly related to the reliability and distance of data transmission. In practical applications, optical signals will experience various losses from the transmitter to the receiver.
In traditional large data centers, 100G is the absolute main force of data transmission, and all infrastructure is built around 100G rate. Although future upgrades and expansions will be considered at the beginning of construction, the explosive development of technology is not considered by everyone. At present, when 400G has been fully applied to the market, 100G rate can no longer meet the needs of data centers. Therefore, the demand for upgrading the transmission bandwidth of data centers is worth putting on the agenda. The old network architecture of the data center cannot be overturned significantly, which means huge construction costs. In this case, the 100G single-wave module with a four-channel 400G module is the best choice for network upgrade.
With the explosive growth of technologies such as artificial intelligence (AI), cloud computing, and 5G, global data traffic has increased exponentially, and the power consumption and bandwidth bottlenecks of traditional optical modules have gradually emerged.
Driven by the explosion of AI computing power and the surge in cloud services, the traffic demand of data centers is shifting from "stable growth" to "dynamic explosion".
Today, with AlphaFold cracking the protein folding code and ChatGPT setting off a wave of generative AI, artificial intelligence is reshaping the world at an unprecedented speed. However, behind these disruptive technologies, there is an often overlooked "unsung hero" - the data center network.
Introduction: When the speed of light meets the torrent of bitsIn the automated workshop of Zhejiang Zhaolong Interconnect, a high-speed chip mounter is assembling indium phosphide laser chips on a ceramic base with an accuracy of 0.02 mm.
As a low-cost, high-coverage, and highly mature network communication component, 10G optical modules are widely used in various network transmission environments.
Light can be the carrier of information. In the optical communication industry, light is the cornerstone of optical communication. We all know that light has different wavelengths, which are divided into visible light and invisible light according to different wavelengths.
Nowadays, we live, work, and study in all aspects. The rise of AI is inseparable from the computing power support of data centers, and computing power requires a high-speed communication network.
The wave of AI has swept the world, bringing exponentially growing data computing needs. Traditional network data centers are facing unprecedented pressure.

What is InfiniBandInfiniBand, the rising star in the communications industry, has become the focus of the current industry following the development of AI. InfiniBand is a high-performance, low-latency, high-bandwidth communication architecture and network protocol.
Fiber optic communication cannot do without the support of optical modules. There are a large number of optical modules on the market, which also causes many people to have a limited understanding of optical modules and not know how to choose the optical modules that suit them.
