Laser Beam Fiber Collimator 2.5mm Optical Collimator

Multi-Wavelength Fiber Collimator for Fiber Optic Communication

Efficient fiber collimator: an optimized tool for laser beam focusing

The fiber collimator converts scattered light into a collimated beam through precise coupling between the lens and the fiber, significantly improving the focusing accuracy and energy utilization of the laser beam. The core lies in the precise alignment of the lens with the fiber end face (tilt angle<0.5 °), combined with an 8 ° tilt angle (APC type) polishing process, which can effectively suppress end face reflection, with a return loss of ≥ 50dB, ensuring that the beam maintains a low divergence angle (typical value 0.01 °) during long-distance transmission. For example, in high-precision scenarios such as laser processing and medical equipment, this design can reduce optical path offset and improve system response speed and reliability.

High performance fiber collimator: an enhancer of overall system performance

By optimizing the coupling process between the lens and the fiber (such as aberration reduction design for non spherical lenses), the fiber collimator can achieve low insertion loss (≤ 0.3dB) and high transmittance (≥ 90%), while maintaining anti vibration performance (mechanical stability up to 0.01mrad). For example, in long-distance transmission scenarios such as 5G base stations and data centers, this design can reduce optical signal attenuation and improve network throughput; Its high return loss (≥ 50dB) characteristic can also reduce reflected light interference, ensure signal integrity, and is suitable for high bandwidth, low latency optical communication networks.

Single mode fiber collimator: guarantee for long-distance signal transmission

The single-mode fiber collimator ensures low mode dispersion of the beam during long-distance transmission by matching the mode field diameter (8-10 μ m) of the single-mode fiber (SMF). For example, in scenarios such as cross ocean optical cables and urban backbone networks, this design can reduce signal distortion and improve transmission distance (typical value>100km). Its high return loss (≥ 50dB) characteristic can also suppress end face reflection, making it suitable for DWDM wavelength division multiplexing systems and meeting the requirements of high-density and high-capacity optical communication.

Dual mode fiber collimator: an implementer of efficient beam collimation

The dual-mode fiber collimator achieves efficient beam collimation and low insertion loss (≤ 0.3dB) by matching the mode field diameter (50/62.5 μ m) of the multimode fiber (MMF). For example, in short distance transmission scenarios such as data center interconnection and industrial automation, this design can improve the efficiency of optical signal coupling and reduce system costs. Its multi-core options (single fiber/dual fiber/quad fiber) further expand its application range, meeting diverse needs from home broadband to industrial grade networks.
