Ⅰ. Accelerated Localization of Optical Modules: Triple Drivers of Policy, Technology, and Corporate Practice Driven by the explosive growth of AI computing power and the large-scale application of 5G, optical modules, as a core component of communication infrastructure, are entering a critical window of opportunity for domestic substitution. ETU-Link Technology Co., Ltd. more than a decade of...
When AI models are trained in hours and autonomous driving processes massive amounts of data in real time, 800G optical modules are an indispensable high-speed transmission foundation. They are not merely "upgrades to network cables," but core components supporting the operation of global digital infrastructure. Companies like ETU-LINK, deeply rooted in the field of optical communication, are prov...
In the field of optical communication, optical modules are key components for realizing photoelectric signal conversion, and their quality and performance directly affect the stable operation of the entire communication system. As an optical communication solution provider serving over 100 countries, ETU-LINK Optical Communication optical modules have already passed CE, FCC, RoHS, FCC, ISO9001 and...
When we transfer large files or use VR devices for remote meetings on a daily basis, optical modules are the core components for efficient data interaction. The "optical interface" connecting the optical module and the optical fiber is the key to stable transmission of optical signals. Slight deviations may cause signal anomalies. I. 1 Micron: The “Precision Red Line” of Optical Interfaces The coa...
In 100G optical communication networks, QSFP28 (Quad Small Form-Factor Pluggable 28) is the mainstream packaging standard. It is key to high-speed interconnection in data centers and telecommunications networks, and directly affects the deployment efficiency of optical modules and network performance. I. Core Design of QSFP28 Packaging 1. Compact size: approximately 18.3mm×56.5mm×8.5mm, only 1/5 o...
With the increasing demand for network bandwidth in scenarios such as 5G base station deployment, data center interconnect (DCI), and high-definition video transmission, 100G optical modules have become the mainstream choice. 100G Single-fiber Optical Modules, with their core advantage of enabling bidirectional transmission over a single fiber, are becoming a key device for conserving fiber resour...
In mid-to-high-speed optical communication scenarios, the 25G SFP28 Optical Module has become mainstream due to its characteristic of "balancing speed and cost". ETU-Link has been deeply engaged in this category and has created cost-effective products that are suitable for multiple scenarios, covering core needs such as data centers, enterprise parks, and 5G edge computing. I. Product Features: Co...
In optical communication systems, optical modules are the core of optical signal transmission, and their performance is crucial to network stability and reliability. However, when long-distance optical modules are directly connected to short-distance optical fibers without attenuation, the optical components at the receiving end are easily damaged. This involves complex optical power management an...
In fiber-optic communication systems, long-distance optical modules, due to their high transmit optical power, are highly susceptible to damage to receiving devices when directly connected to shorter optical fibers. This article analyzes the mechanisms of optical power overload, typical damage scenarios, and protective measures, providing technical references for engineering practice. I. Physical ...
Every optical module of ETU-LINK Optical Communication carries the confidence of "factory-quality"! In the field of communication equipment, the quality of optical modules is directly related to the stability and security of the entire communication link. We always regard the testing link as the core of quality control, using strict standards and comprehensive guarantees to ensure that every custo...
CWDM and DWDM, the "two brothers" in fiber optic communications, differ by only one letter in their names, but the difference is huge! Today, this article will explain the core differences and help you quickly distinguish them. Ⅰ. Transmission Capacity: Worlds Apart Technically, both rely on wavelength division multiplexing (WDM) technology, but they differ significantly in key parameters. DWDM (D...
Did you know? In the world of optical transceivers, there's a subtle yet crucial role: the gold finger. Don't underestimate these glittering golden contacts at the end of an optical module; each one carries the weight of a "bridge for data transmission." When an optical module is inserted into a device, the gold finger engages directly with the connector, ensuring reliable transmission of electric...
