Kunshan Guangjin focuses on the research, development, production, and sale of fiber optic connectivity components, committed to providing comprehensive fiber optic connectivity solutions for data centers, enterprise networks, and telecom operators. Their main products include fiber optic heat shrink tubes, fiber optic adapters, fiber optic connectors, and fiber optic patch cords.

Fiber optic adapters primarily facilitate the precise alignment of two fiber optic ends, offering simple operation, stability, reliability, and long lifespan. They are responsible for connecting equipment and systems, allowing optical signals to transmit through designated channels to achieve specific objectives, with the flexibility to be disconnected at any time.

There are various forms of fiber optic connectors, with APC connectors commonly used in EPON networks. The end face of APC connectors is polished at an 8-degree angle to reduce reflection, with an industrial standard return loss of -60dB. APC connectors feature precise, predetermined angles, radii, and pre-polished ferrules, providing excellent performance and compatibility with NTT-FC standard or compact latching configurations without this standard.
