Product Usage:Two Ethernet cables are connected to form one long Ethernet cable through this product.
Both sides are RJ45 connectors, for connecting or extending use.
What should I do if the Ethernet cable is too short?
Look at this! Network direct connection! Used for extending network cables.

The difference between the old large-size direct-connect boards and the new small-size direct-connect boards.The older large-size PCB board with direct connections is three times larger than the new small-size board, and the shielding is soldered onto the PCB board. The shielding on both sides is connected. However, because the small PCB board is small, the shielding cannot be soldered onto the PCB board, so the shielding on both sides is not connected. The performance and appearance of both models are generally similar.
