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.
Optical modules undergo rigorous testing and quality inspection procedures before shipment, including incoming material inspection, parameter testing, aging testing, actual device testing, and end-face inspection. All test results must meet standard levels; otherwise, the optical module will be returned to the production line for readjustment. Understanding these tests helps in identifying the quality of optical modules.
With the commercialization of AI, data centers have become the darling of the new era. The computing power of data centers is an important bargaining chip for major manufacturers to occupy the right to speak in the AI era. At the physical layer of the data center, as the core transmission carrier of data traffic, optical modules, which were once just standard accessories for network equipment, are being pushed to the forefront of the computing power competition by AI. From the rate evolution from 400G to 1.6T, and then to the technological leap from traditional pluggable to CPO, the impact of AI on optical modules is getting wider and deeper. This article will analyze in detail the impact of the AI era on the demand for optical modules.
With the expansion of data centres and with the advent of the AI era, the demand of data transmission is growing unabated. As one kind of network communication technology with stable performance, the 10 Gigabit copper interface has been a valuable choice for data transmission:
In 2026, big data has permeated our lives. We watch high-definition videos online, use AI to help us work and live, store data in the cloud, and use intelligent driving functions in vehicles. Behind each of these applications, massive amounts of data are rapidly traversing between nodes in data centers, metropolitan area networks, and backbone networks. The data connections between these nodes rely on optical modules. Optical modules perform photoelectric conversion, transforming electrical signals into optical signals suitable for long-distance transmission, enabling long-distance, low-latency data transmission.
