In the rapidly evolving world of telecommunications, the 1G SFP LX (Long Reach) transceiver remains a cornerstone of reliable network infrastructure. Operating at a wavelength of 1310nm over single-mode fiber (SMF), these modules facilitate high-speed data transmission across distances up to 10 kilometers. Despite the rise of 10G and 100G technologies, the 1G LX module continues to dominate in enterprise LANs, metropolitan area networks (MANs), and campus environments due to its exceptional balance of cost-efficiency and performance.
As a leading 1g Sfp Lx Manufacturer, Kocent Optec Limited recognizes that global industrial demand is shifting toward robust, low-power, and highly compatible solutions. From smart city deployments in Europe to industrial automation in North America, the 1G SFP LX is the go-to choice for connecting remote nodes where standard copper cabling fails to meet distance requirements.
The rise of Industrial IoT (IIoT) and 5G backhaul has revitalized the demand for Gigabit optical modules. Reliability in harsh environments is now a primary requirement for global procurement teams.
Enterprises are increasingly seeking multi-vendor compatible transceivers to avoid brand lock-in. Our 1G LX modules are coded for compatibility with Cisco, Juniper, Huawei, and more.
From FTTH rollouts in rural areas to high-security banking networks, 1G LX provides the stability required for long-term optical link integrity.
Established in 2012 in Hong Kong as a hi-tech communication enterprise, Kocent Optec Limited has grown into one of China's premier fiber optic termination product manufacturers. We are dedicated to developing and manufacturing a comprehensive range of passive and active categories for telecommunication networks, enterprise data centers, and industrial applications.

As a seasoned 1g Sfp Lx Supplier, we understand the technical nuances that define a superior module. Our transceivers utilize high-quality DFB lasers and high-sensitivity PIN receivers. Key features include:
Our status as a leading manufacturer in China is built on trust. Every module undergoes rigorous "host testing" in our lab, where we verify performance across various switch platforms. This ensures that when you purchase from Kocent Optec, you are receiving a product that meets or exceeds OEM specifications.
By sourcing directly from our factory, global clients benefit from optimized supply chains. We offer the most competitive pricing without sacrificing the quality of components (such as the optical sub-assemblies and IC chips). Our location in the heart of China’s tech hub allows us to respond quickly to market changes and logistical demands.
