What is the difference between jumper and pigtail? How does each apply? Where is it used? In recent days, several friends have left messages to us, asking about the relevant content, and we will sum up this piece together.
What is an optical fiber jumper?
Optical fiber jumper, also known as optical fiber connector, refers to the connector plug installed on both ends of the optical cable to achieve optical active connection. Similar to coaxial cable, but without the mesh shielding layer, used to make a jump line from the device to the fiber optic wiring link. It is generally used for the connection between the optical terminal and the terminal box.
1. Classification of optical fiber jumper
①FC optical fiber jumper: The external strengthening method is metal sleeve, tightening method is turnbuckle. Generally used on the ODF side (the most used on the distribution frame);
(2) SC type optical fiber jumper: connected to the connector of the GBIC optical module, its shell is rectangular, fastening method is to use the plug and bolt type, do not need to rotate. (Most used on router switch transceivers);
(3) ST type optical fiber jumper: commonly used in ODF optical fiber distribution frame, shell is round, fastening method is turnbuckle. For 10Base-F connections, the connector is usually of type ST. Commonly used in optical fiber distribution frame);
LC type optical fiber jumper: the connector connecting the SFP module, it is made of easy to operate modular jack (RJ) latch mechanism. (Optical modules are commonly used.)

Second, how to distinguish single mode and multi-mode jumper
Fiber jumper has single-mode and multi-mode points, let's look at how to distinguish:
Single-mode fiber: the general fiber jumper is shown in yellow, and the connector and protective sleeve are blue; The transmission distance is long.
Multimode fiber: the general fiber jumper is expressed in orange, and some are expressed in gray, and the connector and protective case are beige or black; The transmission distance is short.
Third, what is cable pigtail
Optical cable pigtail, pigtail is also called pigtail, only one end has a connector, and the other end is a broken end of a optical cable core, connected with other optical cable core by welding, often appears in the optical fiber terminal box, used to connect the optical cable and optical transceiver (between the coupler, jumper, etc.).
Pigtails are divided into multi-mode pigtails and single-mode pigtails:
The multi-mode pigtail is orange, has a wavelength of 850nm and a transmission distance of 500m, and is used for short-distance interconnection.
The single-mode pigtail is yellow, there are two wavelengths, 1310nm and 1550nm, and the transmission distance is 10km and 40km, respectively.
Fourth, what is the difference between fiber jumper and pigtail?
What's the difference between pigtails and jumpers? Mainly in the application.
Only one end of the fiber pigtail is an active connector, and both ends of the jumper are active connectors. There are many kinds of interfaces, and different interfaces need different couplers. The jumper can be split into two parts and used as a pigtail, so it can also be understood that the pigtail is a jumper of a joint.
