【"Next-generation communication standard" 40 Gbps】 Category 8 compatible LAN cable compatible with "40GBASE-T" of 40 Gigabit Ethernet, which is ideal for 5G high-speed optical communication. It supports a transmission band of 2000MHz and prevents the transmission speed from dropping due to the connection of multiple devices. Compatible with existing CAT5, CAT5E, CAT6, CAT7 LAN cables, etc. 【SFTP Shield】: Adopts a double shield structure (braided shield and aluminum foil shield) to prevent communication errors due to external electromagnetic interference and noise interference between adjacent cables. The 4-to-8-core oxygen-free copper shielded stranded wire and twisted wire have high pitch accuracy and excellent shielding effect, making them ideal for use in facilities that require EMI (electromagnetic interference) countermeasures. 【CAT8 standard for easy wiring】 With a width of about 4.5 mm, it is easy to handle and easy to wire. At the same time, a high-density polyethylene insulated outer skin is used to protect the wire inside the cable from disconnection and achieve excellent ultra-high durability. Was 【High-precision contact】 Pursuing high-precision connector by making full use of various processing and protection technologies, the contact pin adopts a three-pronged design, secures stable data transfer with a larger contact area, and exceeds 40 Gbps at maximum Ensure high speed and stable speed. The RJ45 connector uses a 50μ gold-plated shielded copper shell to prevent signal deterioration and rust. 【Ultra-durable】 protector to prevent claw breakage, claws made of high quality material, and cable can be prevented from falling off due to claw breakage, and can be firmly fixed to the LAN port for a long period of time. Highly durable PVC material is used for the outer skin, and the tail of the sheath is wrapped with a heat-shrinkable sleeve to ensure safety and reliability. Passed 5000 bending inspections (verified by our company).
