1. what is a fiber optic patch cord?
Fiber optic jumper, also known as fiber optic connector, refers to the cable at both ends are equipped with connector plug, used to achieve optical path activity connection. Similar to coaxial cable, but there is no mesh shielding layer, which is used as a patch cord from the equipment to the fiber optic wiring link. Generally used for the connection between the optical terminal and the terminal box.
1. fiber optic patch cord classification
① FC type optical fiber jumper: the external reinforcement method is to use metal sleeve, and the fastening method is turnbuckle. Generally used on the ODF side (most used on the distribution frame);
② SC type optical fiber jumper: the connector connected to the GBIC optical module, its shell is rectangular, the fastening method is to use the plug pin latch 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, the shell is round, the fastening method is turnbuckle. (For 10Base-F connection, the connector is usually ST type. Commonly used in fiber distribution frames);
④ LC type fiber optic jumper: the connector for connecting the SFP module, it is made of the modular jack (RJ) latch mechanism for easy operation. (Light module commonly used).
2. how to distinguish between single mode and multimode jumper
Fiber jumpers are divided into single-mode and multi-mode. Let's look at the difference:
Single-mode optical fiber: general optical fiber jumper is indicated by yellow, and the connector and protective sleeve are blue; the transmission distance is long.
Multimode fiber: general fiber jumper with orange, and some with gray, joints and protective cover with beige or black; transmission distance is short.
2. what is fiber optic pigtail
Fiber optic cable pigtail, pigtail is also called pigtail, only one end has a connector, while the other end is a broken end of a fiber optic cable core, which is connected to other fiber optic cable cores by welding and often appears in the fiber optic terminal box for connecting fiber optic cables and fiber optic transceivers (couplers, jumpers, etc. are also used between them).
Pigtail is divided into multimode pigtail and single mode pigtail:
The multimode pigtail is orange, the wavelength is 850nm, and the transmission distance is 500m, which is used for short-distance interconnection.
The single-mode pigtail is yellow, with two wavelengths, 1310nm and 1550nm, and the transmission distances are 10km and 40km respectively.
3. fiber optic jumper and pigtail what is the difference?
What is the difference between pigtail and jumping fiber? Mainly in application.
Only one end of the optical fiber pigtail is a movable connector, and both ends of the jumper are movable connectors. There are many kinds of interfaces. Different interfaces need different couplers. The jumper can be divided into two parts and can be used as pigtail, so it can also be understood that pigtail is a jumper of a connector.
