Instead of copper jumper, fiber jumper plays an important role in telecommunication infrastructures, with a great improvement in the properties of repeatability, confidentiality, transmission speed and transmission capacity to realize the data transmission with low loss. For its largely use, there are a wide range of fiber jumpers available on the market developed for different aims, such as, single mode fiber jumpers, duplex fiber jumpers, ST to LC Fiber Jumper, etc. Different fiber jumpers vary from the color of fiber jumpers to their applications, which can be classified by different standard. In this paper, it will mainly introduce the differences between simplex and duplex fiber jumpers that are classified according to different cable quantities.
Many types of fiber jumpers have been developed at different times, for different purposes. On the basis of cable quantities, fiber jumpers can be divided into two types, simplex fiber jumper and duplex fiber jumper. The two fiber jumpers are completely distinct from structure to working principle, which can be used for different applications. From the following figure, you can learn that the left fiber jumper is a kind of simplex fiber jumper and the right one belongs to duplex fiber jumper.
Simplex fiber jumper is tight-buffered and jacketed that has only one fiber cable with one optical core and cladding. The signal will be transmitted over the one fiber cable. In contrast to simplex fiber jumper, duplex fiber jumper is also tight-buffered and jacketed, but has two separate simplex fiber cables working at the same time. The two separate simplex cables have their own jackets linked together by a kind of material. More detailed information about structural differences for simplex and duplex fiber jumpers is shown in the figure below.
As for duplex fiber jumper, it works simply, transmitting the signals by two separate simplex cables from opposite sides. When one cable is sending the signal from one side, another cable can receive the signal and send another signal from the opposite side simultaneously. The speed of transmitting signals over duplex fiber jumper is slower than over simplex fiber jumper, while the reliability of transmitting signals by duplex fiber jumper is higher. For the sake of high reliability of sending and receiving signals, the duplex fiber jumper must be highly recommended.
Completely different from duplex fiber jumper, simplex fiber jumper has only one fiber cable, which means the signal transmission through simplex fiber jumper can be only running in one direction at a time. That’s to say, when the signal is transmitted from one side of the fiber jumper, the other side cannot sending another signal until receiving the previous signal. It is really inconvenient and cannot meet the requirement of the market.
As time goes on, a new type of simplex fiber jumper is developed, designed for transmitting the duplex signals respectively over one fiber cable by using two optical signals with different wavelengths. Hence, the data can be transmit in two directions at the same time. In simple words, when one signal is sending from one side of the fiber cable, another signal with a different wavelength can be also sending from the other side at the same time, without mutual interference. Compared to the duplex fiber jumper, the simplex fiber jumper has a great improvement in the high speed of sending and receiving the signals, which also saves the optical fiber resource.
Did you get the detailed differences between simplex fiber jumper and duplex fiber jumper from this paper? If high reliability is required, you are suggested to choose duplex fiber jumper for your network; for the sake of transmission speed, simplex fiber jumper must be a good choice. Besides, except for simplex and duplex fiber jumper, fiber optic patch cord manufacturer has manufactured many other types of fiber jumpers to meet the market needs since fiber jumper has become an indispensable device in today’s optical network. You should master the features and applications of each fiber jumper, so that you can easily choose the right one for your own network.
