Notice on the arrangement of some employees of our company to participate in skill training this week

Traditional RJ45 modules have exposed many problems in office environments. Installation requires not only specialized tools such as crimping tools and testers, but also strict adherence to the T568A/B wiring standards, making it impossible for ordinary employees to operate. During the deployment of a new office area for an internet company, due to insufficient IT staff, the network cabling for 20 workstations was delayed by 5 days, directly resulting in project launch delays and losses of nearly

In industrial environments, signal transmission in industrial control cabinets faces numerous challenges. Sources of electromagnetic interference are widespread; high-frequency equipment such as motors, variable-frequency drives, and welding equipment generate a large amount of electromagnetic radiation. This radiation, like invisible "interference waves," constantly impacts the signal transmission system. Simultaneously, crosstalk between cables and ground loop interference can also seriously harm signals, potentially leading to data transmission errors and equipment malfunctions.

UL certification holds significant authority in the network infrastructure field, with its standards for RJ45 modules being both scientific and stringent. Based on the UL 498A (2019 edition) standard, there are clear requirements for UL certified RJ45 modules regarding electrical performance, mechanical durability, and fire rating.

In the wave of Industry 4.0 and intelligent manufacturing, the stability of network connectivity directly determines the efficiency and reliability of the production line. Ordinary commercial RJ45 connectors perform well in office environments, but frequently "fail" in high-temperature, dusty, and vibrating industrial environments. Industrial-grade RJ45 connectors, with their IP67/IP68 protection, -45℃ to +85℃ wide-temperature operation, and anti-electromagnetic interference (EMI) features, have become the "lifeline" of industrial networks.

The nominal data rate of Gigabit Ethernet is 1 Gbps (gigabits per second), but to handle the overhead of Ethernet frame preamble, inter-frame gap, etc., the actual line rate of the physical layer (PHY) is designed to be 1.25 Gbps. Therefore, the "1.25G" in the 1.25G optical module refers to the physical layer line rate.

Whether 850nm and 1310nm SFP optical modules can be shared depends on the specific scenario. The core principle is that wavelengths must match for communication, but indirect sharing may be possible with specific technical support.
