Multimode Fiber Pigtail

Fiber pigtails are generally distinguished by color for single mode and multimode resolution.

Fiber optic colors are mainly divided into two categories:

Single mode fiber: Generally, fiber jumpers are indicated in yellow, and connectors and protective sleeves are blue; Long transmission distance.

Multi mode fiber: Generally, fiber optic jumpers are represented in orange or gray, and connectors and protective sleeves are in beige or black; The transmission distance is relatively short.

Why is the thickness of fiber optic tail fibers?

Fiber optic tail fibers have different thicknesses, and the difference in thickness is due to different models of fiber optic. Single mode fiber is 9 microns, while multimode fiber is 50 microns and 62.5 microns. Many small fingers are thicker and thinner, with a diameter of less than one centimeter, which is thicker than a pencil. The outer dimensions of either 1 core or 2 cores are 3mm × 2mm is the outer diameter of about 20mm tied into a circle.

What if the wavelength of the tail fiber is different from that of the optical fiber?

① The optical modules connected by the jumper must have the same wavelength for transmission and reception. Generally, short wave optical modules are paired with multimode jumpers, while long wave optical modules are paired with single-mode jumpers to ensure the accuracy of data transmission During the wiring process, the jumper should minimize the number of loops as much as possible, which can reduce the attenuation of optical signals during transmission. The connector of the jumper should be kept clean. After use, the connector should be sealed with a protective sleeve to prevent oil and dust from entering. If it gets stained, it should be cleaned with a cotton swab dipped in alcohol The tail fiber is relatively slender, with a cross-sectional angle of 8 degrees, and is not resistant to high temperatures. If it exceeds 100℃, it will be damaged. Therefore, it is necessary to avoid using it in high-temperature environments. Fiber optic connectors are an important component of fiber optic communication. In terms of data transmission, the quality of the plug, the manufacturing technology and methods all determine the stability of data transmission.
