Low Loss Single Fiber Bare Fiber Pigtail Lc Sensitive Systems Fc Apc Pigtail

The dual fiber bare fiber head adopts a dual core bare fiber termination structure, and achieves end face flatness (tilt angle<0.5 °) through high-precision cutting technology, ensuring fusion loss ≤ 0.1dB. The bare fiber end face adopts an 8 ° tilt angle (APC type) polishing process, effectively reducing end face reflection light and improving return wave loss (≥ 50dB). This design is suitable for devices such as duplex couplers and splitters, and can provide low insertion loss (≤ 0.2dB) and high anti-interference ability in complex optical path environments. It is particularly suitable for scenarios with strict signal quality requirements such as enterprise private networks and communication infrastructure.

The single fiber bare fiber head adopts a single core bare fiber head structure, and the design without a connector head can reduce insertion loss and reflection loss during signal transmission. The bare fiber end is encapsulated by a tight fitting optical fiber, 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. This design is suitable for the assembly of single-mode devices (such as wavelength division multiplexers) and can provide stable and reliable signal transmission performance in long-distance communication.

The bare fiber port of the dual fiber bare fiber head adopts tight fitting fiber packaging and 8 ° oblique polishing process, which significantly improves durability by reducing mechanical damage to the end face. Its dual fiber core structure can synchronously transmit signals and maintain low insertion loss (≤ 0.2dB) and high return loss (≥ 50dB) in complex optical path environments (such as high temperature and high humidity scenarios). This design is suitable for high-intensity usage scenarios such as communication base stations and data centers, and can extend the service life of devices.

The single fiber bare fiber head is designed with no connector and tightly wrapped in fiber optic packaging, effectively reducing external electromagnetic interference and improving signal transmission stability. The bare fiber end face adopts an 8 ° oblique angle (APC type) polishing process to ensure a return loss of ≥ 50dB, which is suitable for the assembly of single-mode devices (such as couplers). In long-distance communication, this design can provide low insertion loss (≤ 0.1dB) and high anti-interference ability, especially suitable for scenarios with strict signal quality requirements such as telecommunications and data centers.
