Bare Fiber Pigtail without connector
A single fiber bare fiber head is the core component in fiber optic connections, with one end being a bare fiber core cut (without a connector) and the other end being a fiber core cut of the optical cable, which requires optical path continuity through fusion splicing. This design is suitable for the assembly of high-precision fiber optic passive devices such as couplers and splitters. The bare fiber end is fixed to the device port through fusion splicing technology to form a low loss optical path. The outer diameter of the bare fiber end is usually 0.9mm or 2.0mm for tight fitting optical fibers, without additional sheath protection. End face cleaning and fusion splicing need to be carried out in a dust-free environment to ensure signal transmission stability.

The bare fiber end face of the low loss single fiber bare fiber head adopts an 8 ° oblique angle (APC type) polishing process, which significantly improves the return loss (≥ 50dB) by reducing the reflected light on the end face. The flatness of its end face is controlled at a tilt angle of<0.5 °, combined with high-precision welding technology (such as arc welding method) to ensure welding loss ≤ 0.1dB. This design is suitable for long-distance single-mode transmission (1310nm/1550nm wavelength), and can effectively reduce signal attenuation and improve optical path reliability in the assembly of passive fiber components.

Professional single fiber bare fiber head supports connectionless design, with customizable length (0.5-2 meters) to meet the assembly needs of high-density devices. Its bare fiber end is encapsulated with tight fitting optical fibers, making it easy to strip and fuse on site, while also adapting to various passive device interfaces (such as LC and SC types). Customized length can reduce fiber optic cable redundancy and optimize wiring space, especially suitable for scenarios such as data centers and communication base stations that require strict space utilization.

The dual fiber bare fiber head adopts a dual core bare fiber termination structure, and achieves dual channel optical path connection through synchronous fusion splicing technology. The bare fiber end face also adopts an 8 ° oblique angle design to ensure the synchronization and stability of the dual fiber core signal transmission. This design is suitable for devices such as duplex couplers and splitters, supporting multi-mode (850nm) and single-mode (1310nm/1550nm) transmission. It can provide low insertion loss (≤ 0.2dB) and high return loss (≥ 50dB) signal transmission performance in complex optical path environments.
