Classification of Fiber Optic Patch Cords

October 10,2021

By mode: divided into single-mode fiber and multimode fiber

Single-mode fiber: the general color of the fiber patch cord is yellow, the connector and protective cover is blue; the transmission distance is longer.

Multimode fiber: OM1 and OM2 jumper is orange, OM3 and OM4 jumper is aqua green, transmission distance of OM1 and OM2 is 550 meters at gigabit rate, transmission distance of OM3 is 300 meters at 10 gigabit rate, transmission rate of OM4 is 400 meters; connector and protective jacket are beige or black.

Classification by connector type.

common types of fiber optic patch cords are LC fiber optic patch cord SC fiber optic patch cord FC fiber optic patch cord ST fiber optic patch cord these four types of fiber optic patch cords.

① LC fiber patch cable: it is made of easy-to-operate modular jack (RJ) latch mechanism, connecting SFP optical modules, commonly used in routers.

② SC fiber patch cord: its housing is rectangular, fastened by plugging pin latch type, do not need to rotate, connecting GBIC optical modules, routers switches with the most, with low prices, access loss fluctuations and other characteristics;.

③ FC fiber optic patch cord: the external protective sleeve is a metal sleeve, fastening method is screw fastening, wiring frame is used most often. With the advantages of strong fastening, anti-dust, etc.

④ST fiber patch cord: the shell is round, fastening method for the screw buckle, fiber core exposed, plug inserted after rotating half a week there is a bayonet fixed, mostly used in fiber distribution frame.

Classification by application.

Fiber optic patch cords are generally classified into MTP/MPO fiber optic patch cords, armored fiber optic patch cords, conventional fiber optic patch cords, etc. according to the application of patch cords.

①MTP/MPO fiber patch cord: commonly used in the wiring process requires high-density integration of fiber optic line environment, its advantages: the use of simple push-pull locking structure, easy to install and remove, save time and cost, and can maximize the service life.

② Armored fiber optic patch cords: commonly used in server rooms and suitable for use in harsh environments. Its advantages: no need to use protective sleeving, can prevent moisture and fire, with anti-static and acid and alkali resistance, can save space and reduce construction costs.


③Conventional fiber optic patch cord: compared with MTP/MPO fiber optic patch cord and armored fiber optic patch cord, it has strong scalability, compatibility and interoperability, and can effectively reduce costs.
