This inline coupler has two options: Cat5e (100MHz bandwidth/100Mbps transmission) and Cat6 (250MHz bandwidth/1000Mbps transmission), meeting different bandwidth needs. The UTP unshielded structure requires no additional shielding, suitable for low-electromagnetic interference scenarios; it adopts RJ45 female-to-female inline design, enabling tool-free plug-and-play connection to extend cable distance quickly. Gold-plated contacts resist oxidation, effectively reducing signal attenuation and crosstalk, compatible with 22-24AWG standard network cables. It can extend cables between routers, switches and devices like computers and printers, ensuring stable 100Mbps and 1000Mbps network transmission.
