Fiber jumper interface end face type

Many friends are familiar with fiber optic patch cords. It is also called optical fiber connector. Many people do not know much about the end face types and applicable fields of fiber optic patch cords. Sometimes they even need to know the fur. And the applicable fields are limited. In order to have a deeper understanding of the end face types of fiber jumper interfaces, let's learn together.

Classification of fiber patch cords

①FC type optical fiber jumper: The external strengthening method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (the most used on the patch panel)

②SC type optical fiber jumper: the connector connecting the GBIC optical module, its shell is rectangular, and the fastening method is the plug-and-pull type, which does not need to be rotated. (Most used on router switches)

③ST-type optical fiber jumper: commonly used in optical fiber distribution frame, the outer shell is round, and the fastening method is turnbuckle. (For 10Base-F connections, the connectors are usually ST type. Often used in fiber optic distribution frames)

④LC-type fiber jumper: a connector for connecting SFP modules, it is made with a modular jack (RJ) latch mechanism that is easy to operate. (commonly used by routers)

⑤MT-RJ type optical fiber jumper: a square optical fiber connector with integrated transceiver, one dual-fiber transceiver integrated

ST and SC connectors are often used in general networks. After the ST head is inserted, it is fixed by a bayonet half-circle, but the disadvantage is that it is easy to break; the SC connector is directly inserted and unplugged, which is very convenient to use, but the disadvantage is that it is easy to fall out; It is reliable and dust-proof, but the disadvantage is that the installation time is slightly longer. MTRJ type fiber optic patch cord consists of two high-precision plastic molded connectors and fiber optic cables. The outer parts of the connector are precision plastic parts, including a push-pull plug-in clamping mechanism. Suitable for indoor applications in telecommunication and data network systems.

Optical fiber modules: generally support hot swap, the optical fiber interface used by GBIC is mostly SC or ST type; SFP, namely: small package GBIC, the optical fiber used is LC type.

ZR Cable Fiber Patch Cord

Fiber used:

Single mode: L wavelength 1310 single mode long distance LH wavelength 1310,1550

Multimode: SM wavelength 850

SX/LH means single mode or multimode fiber can be used

In the label indicating the pigtail connector, we often see "FC/PC", "SC/PC", etc., the meanings are as follows

1 The front part of "/" indicates the connector type of the pigtail

The "SC" joint is a standard square joint, made of engineering plastics, which has the advantages of high temperature resistance and not easy to be oxidized. The optical interface on the side of the transmission equipment generally uses the SC connector

The "LC" connector is similar in shape to the SC connector and is smaller than the SC connector.

The "FC" connector is a metal connector, which is generally used on the ODF side. The metal connector can be plugged more frequently than plastic.

There are many varieties of connectors. In addition to the three types described above, there are MTRJ, ST, MU, etc.

2. The back of '/' indicates the cross-section process of the optical fiber connector, that is, the grinding method

"PC" is most widely used in telecom operators' equipment, and its connector section is flat.

The attenuation of "UPC" is smaller than that of "PC". It is generally used for equipment with special needs. Some foreign manufacturers use FC/UPC for the internal jumper of ODF racks, mainly to improve the indicators of the ODF equipment itself.

Scope of use:

A: Optical fiber communication system B: Optical fiber broadband access network C: Optical fiber CATV D: Local area network LAN E: Optical fiber instrument meter

F: Optical fiber sensor G: Optical fiber teaching data transmission system H: Test equipment
