The N035-001 2-to-1 RJ45 Splitter Adapter Cable (M/2xF) allows you to transmit two 10/100 Ethernet signals through one Cat5/Cat5e cable, saving you the time, effort and cost of adding a second cable drop. Two N035-001 units are required: one connected to two network devices, such as servers or computers, and one connected to two ports of a network switch. A single Cat5/Cat5e cable connects the two N035-001 units through a four-pair UTP wall plate or patch panel. The RJ45 jacks transmit on 1, 2, 3 and 6. Drilled flanges allow you to mount the unit on a wall. The N035-001 cannot be used to share two computers on one network line.
