What fiber is suitable for the rectangular optical port?

　　Rectangle optical ports are usually suitable for fiber optic connectors such as FC, LC, or MT-RJ. Here is a detailed analysis of these adapters:

　　FC connector:

　　Shape: Round with threads, but in some cases, FC connectors may be equipped with rectangular adapters for easy installation on specific devices or panels.

　　Features: Metal connector, with good durability and high number of plugging and unplugging. Usually used in distribution frames, it is a common type of connector in telecom operator equipment.

　　Application scenarios: Suitable for applications that require high stability and durability, such as long-distance communication, data centers, etc.

　　LC connector:

　　Shape: Snap-on square, SMaller than sc connectors, easier to install at high density. LC connectors are usually equipped with rectangular adapters to adapt to the interface requirements of different devices.

　　Features: Adopt moulded plug-in coupling type, easy to install and disassemble. With high transmission rate and low attenuation.

　　Application scenarios: Widely used in fiber optic switches, routers and other network equipment, supporting high-density fiber optic connections.

　　MT-RJ connector:

　　Shape: square, with a dual-fiber transceiver integrated at one end, usually also equipped with a rectangular adapter for easy installation.

　　Features: It has a small size and high integration, making it suitable for applications that require the simultaneous transmission of multiple optical signals.

　　Application scenarios: Common in some specific communication devices, such as some Huawei products.

　　When selecting a fiber optic connector with a rectangular optical port, the following factors need to be considered:

　　Device compatibility: Ensure that the selected connector is compatible with the device's interface.

　　Transmission performance: Choose the appropriate transmission rate and attenuation performance according to the application requirements.

　　Installation environment: Consider the size, shape, and installation method of the connector to adapt to different installation environments.

　　Overall, the rectangular optical port can be adapted to FC, LC, or MT-RJ types of fiber optic connectors, depending on factors such as device compatibility, transmission performance, and installation environment.
