Duplex Patch cord comes from “duo” that means “two”, and “plex” refers to “weave” or “fold”. A duplex system has two clearly defined paths with each path providing information in only one direction, that is A to B over one path, B to A over the other. Compared with half-duplex, a full-duplex system, or sometimes called double-duplex allows communication in both directions and allowing this to happen simultaneously.
Duplex Patch cord Product Overview
Duplex Patch cord consists of two separate fiber optic strands. Typically found in a zip cord construction format, which is most often used for duplex communication between devices where requires simultaneous, bi-directional transfer, workstation, fiber switches and servers, fiber modems.
Simplex fiber patch cable only contains one fiber and one single outer jacket, which means that information is running in only one direction. This cable is often utilized in applications that require one way data transfer.
According to the ITU-T definition, a simplex circuit is one where signals can flow in only one direction at a time. One end is the transmitter, while the other is the receiver and that is not reversible. مثلا, in TV, audio or visual information flows from transmitter to numerous receivers. Patch Cords are used to provide optical connection for fiber optic electronics. The use of the patch cord provides a quick and easy method for routing fiber patches in data centers, head-ends, cellular hubs and central offices. The patch cord can be used in interconnect or cross-connect path connecting the incoming fibers to the electronic equipment and providing patching within the fiber paths. Patch Cords include simplex, duplex and Multi-fibers assemblies.
