In the last episode, we talked about the connector type, now let’s talk about the difference between “Simplex” and “Duplex” cables.

Simplex is a cable that uses Fiber Optic 1 core to transmit the signal. Such as a device that sends a one-way signal Or devices that can send – receive signals different wavelengths in Fiber Optic, only 1 Core (WDM: Wavelength Division Multiplexing) such as Bi-di Optical Module or FTTH system.

Duplex is a cable that supports 2-core Fiber Optic transmission, so the cable format may be a two-core Simplex cable. Or use a Zipcord that looks like a Simplex cable, but the two lines are connected together. For ease of use and storage, Duplex cables are used with general network systems that divide each core signal into transmit and receive.

In the next episode, we’ll talk about the words “Singlemode” and “Multimode” ?
