Single Mode Fiber Pigtail

The single mode tail fiber is yellow, with two wavelengths, 1310nm and 1550nm, and transmission distances of 10km and 40km, respectively.

Tail fiber, also known as tail wire, has only one end with a connector, while the other end is a broken end of a fiber optic cable core. There are multi-core optical fibers inside the outdoor fiber optic cable, which reach the user's location. The tail fibers are connected to the fiber optic cable core through fusion, and the fusion joint is fixed in the fiber optic terminal box. Separate the corresponding fiber cores for users to connect optical cables and fiber transceivers.

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.

What does the length of the tail fiber of the optical fiber affect?

The length of the optical fiber has little impact on the network speed, as one kilometer of optical fiber usually only has a attenuation of 0.5db. If the operator arranges the optical network reasonably, this optical fiber can theoretically reach a distance of over 10 kilometers, so a few meters or tens of meters longer at home can almost be ignored for the optical network. But bending the optical fiber has a significant impact on the network speed. Generally, the diameter of the optical fiber is not less than 10 centimeters. If the diameter is too small, it will cause the beam to refract too much in the optical fiber, causing light loss, and causing packet loss or even optical signal interruption in the optical fiber.

The Influence of Single Mode Pigtail on Multimode Fiber Fusion:

Single mode fiber and multimode fiber cannot be directly fused due to their different core diameters. To be connected through a single mode multimode fiber optic converter. Single mode and multimode can also be converted to each other, achieving networking functions such as multi machine communication and relay conversion, mainly solving the problem of mutual conversion between multimode and single mode optical fibers in fiber optic cabling.

Single mode multimode converters are mainly used for mutual conversion in single multimode fibers or single dual fiber fibers, and can also be used for mutual conversion of fiber wavelengths (850nm/1300nm/1310nm/1550nm).

This module adopts an advanced fiber optic conversion integrated circuit solution, with low chip temperature rise and more stable performance. It provides fiber optic connection status indicator lights, multi mode (MM) FL1 and single mode (SM) FL2 status lights, making debugging more intuitive and convenient. The optoelectronic integrated module provides good optical and electrical characteristics, ensuring reliable data transmission and long working life.
