Fiber optic jumpers are widely used transmission media in optical transmission, which can be divided into single-mode fiber optic jumpers and multimode fiber optic jumpers according to the type of fiber. The core diameter of single-mode fiber optic jumpers is relatively small, which is 8 μ M to 10 μ m. And it propagates light along a straight path without bouncing off the edges, completely avoiding dispersion and waste of optical energy. Therefore, single-mode fiber jumpers can achieve lower attenuation, allowing signals to propagate faster and farther.
Types of single mode fiber optic jumpers
Single mode fiber optic jumpers can be divided into two types: OS1 single mode and OS2 single mode. OS1 adopts a tight sleeve structure, suitable for indoor applications with a maximum distance of 10 kilometers, and has a maximum attenuation value of 1.0 db/km in the 1310nm and 1550nm bands. OS2 is usually designed with loose sleeves and is suitable for outdoor applications with a maximum distance of up to 200km. The maximum attenuation value in the 1310nm and 1550nm bands is 0.4db/km. Both OS1 and OS2 fiber optic jumpers support Gigabit and 10G Ethernet links, and in addition, OS2 fiber optic jumpers can support 40G and 100G Ethernet links.
Advantages and disadvantages of single mode fiber optic jumpers
It should be noted that the advantages and disadvantages of the single mode fiber patch cords we mentioned here are mainly relative to the multimode fiber patch cords.
Advantages of Single Mode Fiber Optic Jumpers
Transmission distance: Single mode fiber optic jumpers can support data transmission over longer distances due to lower attenuation. For example, multimode fiber optic jumpers typically have a maximum transmission distance of several hundred meters, while single-mode fiber optic jumpers can reach up to 200km.
Bandwidth capacity: Single mode fiber optic cords can provide higher bandwidth than multimode fiber optic cords.
Inter mode dispersion: Single mode fibers only transmit one mode of light, therefore there is no inter mode dispersion.
Transmission rate: Due to the absence of inter mode dispersion, mode noise, and some other effects, single mode fiber optic jumpers can transmit signals at higher rates.
Disadvantages of Single Mode Fiber Optic Jumpers
High coupling difficulty: Due to the small core diameter of single-mode fibers, coupling light into single-mode fibers is more difficult than coupling into multimode fibers.
Higher cost: Due to the high cost of optical terminals, the cost of using single-mode fiber optic jumpers is higher than that of multimode fiber optic jumpers.
More stringent technology: Manufacturing and processing single-mode fibers is more difficult than dual-mode fibers.
