ST Fibre Optic Patch Cord

About ST Fibre Optic Patch Cord

 

ST (Straight Tip) Fiber Optic Patch Cord is a common type of fibre optic connector, widely used in network communication and fibre optic systems for its reliability and ease of use. The following will introduce ST Fiber Optic Patchcord from definition, structure, classification and application.

 

1. What is ST Fiber Optic Patchcord?

ST fiber optic patch cable is a kind of fiber optic patch cable with ST connector as the port, which is usually used for equipment connection in fiber optic transmission.ST connector was firstly developed by AT&T, and its plug is designed as a cylindrical shape, with bayonet connection which is pushed in and rotated by 90 degrees to lock, and it has good mechanical properties and stability.

 

2. Structure of ST fibre optic patch cable

Connector part: ST connector adopts metal shell, the port is round, and the core part is ceramic or plastic fibre optic insert. After inserted into the fibre optic interface, it is fixed by rotary locking mechanism.

Optical fibre part: Patch cords are usually made of single-mode or multi-mode optical fibre, with a wear-resistant protective sleeve on the outside, which can effectively protect the optical fibre from physical damage.

Protective sleeve: Mostly made of PVC or LSZH (Low Smoke Zero Halogen) material, used to provide flame retardancy and durability.

 

 

3. Classification of ST Fibre Optic Patch Cords

According to the different types of optical fibers and connection methods, ST fiber optic patch cords are mainly divided into the following categories:

Classification by transmission mode

Single-mode fibre optic patch cords: usually yellow, with small core diameter, suitable for long distance data transmission.

Multi-mode fibre optic patch cable: usually orange or aqua blue, with larger core diameter, suitable for short distance or high speed transmission in LAN.

 

 

4. Advantages and disadvantages of ST fibre optic patch cords

Advantages:

High connection stability: bayonet design effectively avoids plug loosening.

Easy to install: simply insert and gently rotate to complete the connection.

Strong versatility: still widely used in many traditional optical fibre systems and equipment.

Disadvantages:

Low interface density: not suitable for high-density cabling scenarios due to its large plug size.

Performance limitation: Compared with new connectors (e.g. LC), it is slightly inferior in terms of insertion loss and return loss.

 

5. Application areas

ST fibre optic patch cords are mainly used in the following areas:

Local Area Network (LAN): Multimode ST patch cords are commonly used for short distance LAN cabling.

Fiber optic communication equipment: such as fiber optic transceivers, fiber optic switches, etc.

Industrial control system: Due to its high reliability, ST patch cords are commonly used in industrial automation control field.

Video transmission system: used for long distance or high quality video signal transmission.

 

We can offer a wide range of communication fiber optic cables, such as AVAGO Industrial Jumper Cables. ST/SMA/FC Patch Cables.
