Types of Fiber Optic Patch Panels in Fiber Optic Communication Systems

Fiber optic communication systems employ a variety of fiber optic patch panels, which are classified primarily based on interface types, structural forms, and connection methods. The following are some common types of fiber optic patch panels:

1. LC-type Patch Panel: The LC interface, fully known as Lucent Connector, is a type of fiber optic interface commonly used in Ethernet switches. It features a modular jack (RJ) latching mechanism for convenient operation, offering high density, speed, reliability, and compactness. LC-type patch panels are typically compatible with SFP modules (SFP optical modules default to LC interfaces) and are suitable for data transmission applications.

2. SC-type Patch Panel: The SC interface, standing for Square Connector, is a snap-in type interface developed by Japan's NTT company. SC-type patch panels have a rectangular housing and employ a plug-in latching mechanism that does not require rotation. They offer ease of insertion and removal, stable connection, and durability, making them widely used in data transmission applications.www.adsscable.cn

3. ST-type Patch Panel: The ST interface, known as Straight Tip, is a round quick-connect connector originally developed by Corning. ST-type patch panels have a round housing and are secured with a screw-type locking mechanism. After insertion, the ST head rotates half a turn to lock into a notch, although it can be prone to breakage, requiring careful handling.www.adsscable.cn

4. FC-type Patch Panel: The FC interface, standing for Fiber Channel, is a polished-type connector that typically uses a special fiber optic ferrule for connection. FC-type patch panels feature a metal sleeve for reinforcement and a screw-type locking mechanism.

5. MU-type Patch Panel: The MU (Miniature unit Coupling) connector is the world's smallest single-core fiber optic connector, developed based on the SC-type connector by NTT. MU-type patch panels have a rectangular housing and employ a self-locking mechanism, suitable for protective connections between optical cables and distribution tail fibers.

6. MT-RJ-type Patch Panel: The MT-RJ-type patch panel builds upon the MT connector developed by NTT, incorporating the same latching mechanism as the RJ-45 LAN electrical connector. It aligns fibers through guide pins installed on both sides of a small sleeve. The connector's end face features a dual-core (0.75mm spacing) arrangement, primarily designed for high-density fiber connections in next-generation data transmission applications.

It is worth noting that there is a wide variety of fiber optic patch panels, and different application scenarios and requirements may necessitate different types of patch panels. When selecting a fiber optic patch panel, it is essential to consider factors such as interface compatibility, fiber type, transmission distance, and installation environment. Additionally, the quality and performance of the fiber optic patch panel directly impact the stability and reliability of the fiber optic communication system, thus emphasizing the importance of selecting reliable patch panel suppliers and products.
