The optical patch cord is the fiber connector connected to the optical module and the end device of the fiber. It is used for the patch cord of the device to the fiber wiring link. It is generally used for the connection between the optical transceiver and the terminal box.
The pigtail is composed of an optical fiber connector and an optical cable. Different from an optical optical patch cord, one end of the pigtail is an optical fiber connector, and the other end is the end of the fiber core of the optical fiber, which is used to connect optical fiber transceivers or optical fiber equipment.
The difference between optical patch cord and pigtail-application
1. Application of optical patch cord
(1) Connection between optical fiber distribution frame or optical fiber information socket and switch
(2) The connection between the switch and the switch
(3) The connection between the switch and the desktop computer
(4) The connection between the optical fiber information socket and the desktop computer
(5) Management, equipment room and work area subsystems.
2. Application of pigtail
(1) Optical fiber communication system
(2) Optical fiber access network
(3) Optical fiber data transmission equipment
(4) Optical fiber CATV
(5) Local area network
(6) Test equipment
(7) Optical fiber sensor
(8) Serial server
(9) FTTH/FTTX
(10) Telecommunications network and pre-termination installation.
Optical fiber jumpers and pigtails should be avoided as far as possible during use, which can effectively reduce the attenuation of optical signals during transmission.
The optical fiber jumper and pigtail must have the same transceiver wavelength. Generally, the multi-mode fiber jumper/pigtail is matched with the short-wave optical module, and the single-mode fiber jumper/pigtail is matched with the long-wave optical module to ensure data. The accuracy of transmission.
The connector of the fiber jumper and pigtail should be kept clean. After use, the connector should be sealed with a protective cover to prevent oil and dust from entering. If it is stained, use a cotton swab dipped in alcohol to clean.
Compared with the fiber jumper, the pigtail is relatively slender and not resistant to high temperature. The pigtail cannot be used in a high temperature environment exceeding 100°C.
