The bare fiber optic head adopts a connectionless design and is effectively isolated from external electromagnetic interference through tight fitting fiber optic packaging technology, ensuring the purity of signal transmission. The bare fiber end face adopts high-precision polishing technology, combined with an 8 ° oblique angle (APC type) design, to increase the return loss to ≥ 50dB, significantly reducing the impact of reflected light on the signal. In electromagnetic sensitive scenarios such as industrial automation and medical equipment, this design can ensure the stability of fiber optic communication and avoid signal distortion caused by interference. For example, in medical imaging equipment, bare fiber optic heads can ensure lossless transmission of high-precision image data, improving diagnostic accuracy.

The dual fiber bare fiber head achieves efficient connection of dual channel optical paths through dual core synchronous fusion technology, which is suitable for high-density fiber communication scenarios. The bare fiber end face adopts an 8 ° oblique angle design to ensure the synchronization and stability of dual fiber core signal transmission, with an insertion loss of ≤ 0.2dB. In space limited environments such as data center cabinets and 5G base stations, this design can save more than 50% of wiring space, while supporting multi-mode (850nm) and single-mode (1310nm/1550nm) transmission, meeting the communication requirements of high speed and low latency. For example, in a cloud computing server cluster, dual fiber bare fiber heads can ensure efficient transmission of massive data.
The high-precision single fiber bare fiber head adopts an 8 ° oblique angle (APC type) polishing process, which reduces the reflected light at the end face and controls the fusion loss to ≤ 0.1dB, significantly reducing signal attenuation. The flatness of its bare fiber end face (tilt angle<0.5 °) is calibrated by a high-precision fusion splicer to ensure the alignment accuracy of the optical path. In long-distance single-mode transmission (1310nm/1550nm wavelength), this design can improve the reliability of the optical path and is suitable for scenarios with strict signal quality requirements such as telecommunications backbone networks and submarine cables. For example, in transoceanic communication, high-precision single fiber bare fiber heads can ensure the stability of signal transmission.
The single fiber bare fiber head is designed without a connector to avoid signal interruption caused by plugging and unplugging, making it suitable for precision signal transmission in medical equipment. The bare fiber end adopts tight fitting fiber optic packaging, which facilitates on-site fiber stripping and fusion splicing operations, and is also compatible with various medical equipment interfaces (such as LC and SC types). In medical imaging equipment such as CT and MRI, this design ensures lossless transmission of high-precision image data and improves diagnostic accuracy. For example, in surgical robot systems, a single fiber bare fiber head can ensure real-time control signals and reduce operational risks.
