Dorelink
The global connectivity market is undergoing a seismic shift driven by the explosion of AI, IoT, and 5G. At the heart of this revolution is the humble yet critical RJ45 switch port and its optical counterparts. As the industry transitions from traditional copper-based Gigabit Ethernet to multi-gigabit (2.5G/5G/10G) and ultra-high-speed fiber optics (100G/400G), the role of specialized manufacturers in China has become more vital than ever.
Dorelink Optical Communications Co., Ltd. stands at the intersection of this transition. While our heritage is deeply rooted in optical transceiver technology, our expertise extends to the structural and signal integrity required for the next generation of Ethernet connectors and switch ports. In today’s industrial environment, a "port" is no longer just a physical interface; it is a complex assembly requiring electromagnetic interference (EMI) shielding, integrated magnetics, and ruggedized durability for harsh environments.
Evolution of multi-port (2x4, 2x6) RJ45 connectors with integrated magnetics (MagJack) to reduce PCB footprint and EMI in enterprise switches.
Enhancing switch port capabilities to support 90W Power over Ethernet (802.3bt), powering smart lighting, high-end PTZ cameras, and Wi-Fi 6/7 APs.
The rise of SFP28, QSFP-DD, and 400G modules, providing seamless bridging between local copper networks and hyperscale cloud backbones.
Waterproof RJ45 (IP67/68) and vibration-resistant connectors for Industry 4.0, smart factories, and edge computing nodes.
Established in 2016, Dorelink Optical Communications has cultivated a reputation for reliability and technical prowess. Our facility in China is not just a factory; it is a center for innovation where 120 professional engineers push the boundaries of signal integrity and optical performance.
