Optical fiber patch cable: After processing the optical fiber cable and optical fiber connector through a certain process, fix the optical fiber connector on both ends of the optical fiber cable, so as to form an optical fiber patch cable with optical fiber cable in the middle and optical fiber connector at both ends.
Classification of optical fiber patch cords
Classified by mode: It is divided into single-mode fiber and multimode fiber
Single mode optical fiber: Generally, the color of Optical fiber patch cable is yellow, and the connector and protective sleeve are blue; Long transmission distance;
Multimode optical fiber: OM1 and OM2 Fiber Cables common are Orange, OM3 and OM4 Fiber Cables common Aqua, and the transmission distance of OM1 and OM2 at Gigabit rate is 550 meters, that of OM3 at 10 Gigabit rate is 300 meters, and that of OM4 is 400 meters; The connector and protective sleeve shall be beige or black;
Classification by Fiber Connector type:
The common types of Optical fiber patch cable include LC Optical fiber patch cable, SC Optical fiber patch cable, FC Optical fiber patch cable and ST Optical fiber patch cable;
① LC Optical fiber patch cable: it is made of modular jack (RJ) latch mechanism with convenient operation. It is connected with SFP optical module and is commonly used in routers;
② SC Optical fiber patch cable: its shell is rectangular, and its fastening method is plug-in pin latch type without rotation. It is connected with GBIC optical module. It is most used in routers and switches, with the characteristics of low price and small fluctuation of access loss;
③ FC Optical fiber patch cable: the external protective sleeve adopts metal sleeve, and the fastening method is turnbuckle, which is most used on the distribution frame. It has the advantages of strong fastening and anti dust;
④ ST Optical fiber patch cable: the shell is round, the fastening method is screw buckle, the fiber core is exposed, and there is a bayonet fixed around the half circle after the plug is inserted. It is mostly used for optical fiber distribution frame
Classification by application:
According to the application of Optical fiber patch cable, Optical fiber patch cable is generally divided into MTP / MPO Optical fiber patch cable, Armored Optical fiber patch cable, conventional Optical fiber patch cable SC LC FC ST MU, etc.
① MTP / MPO Optical fiber patch cable: It is common in the optical fiber line environment requiring high-density integration in the wiring process. Its advantages: simple push-pull locking structure, convenient installation and removal, saving time and cost, and maximizing service life;
② Armored Optical fiber patch cable: Common in machine room, suitable for harsh environment. The utility model has the advantages of no need to use protective casing, moisture-proof and fire prevention, anti static, acid and alkali resistance, space saving and construction cost reduction;
③ Conventional Optical fiber patch cable: Compared with MTP / MPO Optical fiber patch cable and armored Optical fiber patch cable, it has strong scalability, compatibility and interoperability, and can effectively reduce the
