High Precision Bare Fiber Pigtail for Fiber Networks

Single fiber bare fiber head is a key connecting component in fiber optic networks, which consists of a single bare fiber head (without a connector) and achieves precise docking with optical cables or devices through fusion splicing technology. This design is suitable for high-density cabling scenarios, such as data centers, telecommunications rooms, etc., and can significantly reduce signal transmission losses. The bare fiber end adopts a tight fitting fiber optic package with an outer diameter of 0.9mm or 2.0mm. In a dust-free environment, high-precision fusion splicing machines (such as arc fusion splicing) are used to achieve end face flatness (tilt angle<0.5 °), ensuring fusion loss ≤ 0.1dB. The single fiber bare fiber head supports single-mode (1310nm/1550nm) and multi-mode (850nm) transmission, providing stable and reliable signal transmission performance in long-distance communication.

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. Its connectionless design can reduce external electromagnetic interference and improve signal transmission stability. The dual fiber bare fiber head and bare fiber end face are also polished at an 8 ° angle (APC type) to ensure a return loss of ≥ 50dB, suitable for devices such as duplex couplers and splitters. In complex optical environment, this design can provide low insertion loss (≤ 0.2dB) and high anti-interference ability, especially suitable for scenarios with strict signal quality requirements such as enterprise private networks and communication infrastructure.

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. For example, in a wavelength division multiplexer (WDM), a low loss single fiber bare fiber head can ensure synchronous transmission of multi wavelength signals and reduce optical path crosstalk.

The dual fiber bare fiber head adopts a dual core bare fiber termination structure, and achieves dual channel optical path connection through synchronous fusion technology. Its bare fiber design can significantly save wiring space. This design is suitable for high-density device assembly, such as data center cabinets, communication base stations, etc., which can reduce fiber optic cable redundancy and optimize wiring space. The dual fiber bare fiber head and bare fiber end face are also polished at an 8 ° angle (APC type) to ensure the synchronization and stability of the dual fiber core signal transmission. For example, in a duplex coupler, this design can provide signal transmission performance with low insertion loss (≤ 0.2dB) and high return loss (≥ 50dB), while saving more than 50% of wiring space.

High quality 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. For example, in fiber optic terminal boxes, high-quality single fiber bare fiber heads can be quickly connected to optical cables through fusion splicing technology, improving installation efficiency.
