How to distinguish single and multi-mode fiber jumpers

　　fiber optic jumpers can be divided into single-mode jumpers and multi-mode jumpers according to different tranSMission media. The distinction between the two is as follows:

　　First, the appearance difference

　　Cable Color:

　　The appearance of the single-mode jumper is usually yellow.

　　The appearance of multi-mode jumpers comes in a variety of colors, such as orange, turquoise, rose red, and lemon green.

　　optical cable printing:

　　The printing of single-mode jumpers usually has the words "SM" or "G652", "G655", "G657", "9/125", etc.

　　The printing of multimode jumpers usually has "MM" or "OM3", "50/125", "62.5/125" and other words.

　　Parts Color:

　　The color of the single-mode jumper connector is usually blue or green.

　　The color of the multimode jumper connector is generally off-white.

　　Differences in performance parameters

　　Core diameter:

　　The core diameter of a single-mode jumper is small, usually 9um.

　　The core diameter of the multimode jumper is larger, usually 50um or 62.5um.

　　Transmission characteristics:

　　Single-mode fiber optic jumpers can achieve lower attenuation, allowing signals to travel faster and farther, with transmission distances of up to 100 kilometers or more, and high transmission rates, supporting transmission rates of 10Gbps, 40Gbps, or even 100Gbps or more.

　　Multimode fiber optic jumpers are more suitable for large-capacity data transmission within the same distance range, but the transmission distance is relatively short, usually between a few hundred meters and a few kilometers (OM3 up to 300 meters, OM4 up to 400 meters), and the transmission rate is also higher, but slightly lower than single-mode fiber, usually supporting transmission rates such as 10Gbps and 40Gbps.

　　Application scenarios:

　　Single-mode fiber optic jumpers are mainly used for long-distance and high-speed communication, including telecommunications networks, Internet backbone networks, data centers, enterprise networks, metropolitan area networks, PON, and other long-distance transmission scenarios.

　　Multimode fiber optic jumpers are mainly used in short-distance transmission and high-speed data transmission scenarios such as enterprise internal networks, data centers, campus networks, local area networks, and wide area networks.

　　III. Cost and maintenance

　　Cost:

　　The cost of single-mode fiber jumpers is higher, including the cost of optical modules and jumpers.

　　The cost of multimode fiber optic patch cords is relatively low, making them suitable for projects with limited budgets.

　　Maintenance:

　　The installation and maintenance requirements of single-mode fiber optic patch cords are demanding, requiring professional technicians and equipment.

　　The installation and maintenance of multimode fiber optic patch cords are relatively simple, making them suitable for operation by ordinary technicians.

　　In summary, single-mode jumpers and multi-mode jumpers can be distinguished from various aspects such as appearance color, print logo, part color, core diameter, transmission characteristics, application scenarios, cost and maintenance. In practical applications, it is necessary to choose the appropriate jumper type according to specific needs.
