A 10G single-mode optical module is an optoelectronic conversion device that supports high-speed data transmission of 10Gbps. It uses single-mode fiber for long-distance communication and is widely used in data centers, metropolitan area networks, and 5G networks.

This is because "gigabit" in Ethernet standards usually refers to an effective data transfer rate of 1Gbps (1000Mbps), while 1.25Gbps is the transmission rate of the optical module at the physical layer.

The differences between RJ45 connector models mainly lie in transmission rate, structural design, protection level, and application scenarios. Different models meet diverse needs through differentiated technical parameters and physical characteristics.

In today's world, swept by a wave of digitalization, network connection technology, as the "nerve center" of information transmission, directly impacts the intelligent development of various industries with its stability and efficiency. As a core component of Ethernet communication, the RJ45 connector is experiencing unprecedented market opportunities with the development of emerging technologies such as 5G, the Internet of Things, and the Industrial Internet.

The 8 pins of an RJ45 connector transmit high-speed data through differential signaling. A 100Mbps network uses pins 1/2/3/6, while a Gigabit network uses all 8 pins. In PoE scenarios, some spare pins provide power. Correct wiring is crucial in practice, depending on network standards, cable type, and device requirements, to ensure signal stability and device compatibility.

The RJ45 connector is a standardized interface widely used in network communications, primarily for connecting Ethernet devices (such as computers, routers, and switches) to enable data transmission.

In the aerospace field, millimeter-level connection failures can trigger systemic risks. Data released by NASA shows that 70% of aerospace electronic equipment failures originate from connection system anomalies. A typical case includes a low-Earth orbit satellite experiencing a communication link interruption for 47 minutes due to a sudden change in connector contact resistance, directly impacting ground control tasks. These incidents highlight the critical role of connectors in aerospace systems.

Against the backdrop of the accelerating penetration of in-vehicle Ethernet technology, the automotive electronic RJ45 interface, as a key physical layer component connecting in-vehicle network nodes, its performance stability directly determines the reliability of core functions such as intelligent cockpits and ADAS (Advanced Driver-Assistance Systems). Unlike consumer electronics scenarios, the automotive electronics environment faces harsh operating conditions—temperature cycles from -40℃ to 125℃, mechanical stress caused by continuous vibration, and complex electromagnetic interference generated by the ignition system, radar modules, etc.
