Duplex Fibre Optic Cables are a type of optical fibre cable that contains two strands of fibre, allowing for simultaneous bidirectional communication. These cables are widely used in networking and telecommunication applications due to their ability to transmit large amounts of data over long distances with minimal signal loss. The cables are made up of a core of glass or plastic fibres that transmit light signals and are surrounded by protective coatings to ensure durability and stability. Duplex Fibre Optic Cables are an ideal choice for those looking for reliable and high-speed data transmission.

Frequently Asked Questions (FAQs)
1. Is fiber optic cable full-duplex?
Duplex fibre optic cables can be half-duplex or full-duplex. Half-duplex means that data can be transmitted in two directions but not simultaneously.
2. How many fiber optic cables do I need for full-duplex?
On the other hand, the full duplex system uses two fibers to communicate. This allows one fiber to transmit from point A to point B while the other fiber transmits from B to A. Therefore, both ends of a full-duplex system have both transmitters and receivers.
3. What is simplex vs duplex?
In full duplex mode, the signal is sent in both directions at the same time. In simplex mode, only one device can transmit the signal. In half duplex mode, both devices can transmit the signal, but one at a time.
4. What are the 2 types of fiber optic cable?
There are two types of fibre optic cables – multimode and single-mode. Multimode fibre is capable of carrying multiple light rays (modes) at the same time as it has varying optical properties at the core. Single-mode fibre has a much smaller core size (9 microns).
