Stainless Steel Fiber Collimator 1550nm 1650nm Dual Fiber Collimator

Cost-Effective Fiber Collimator for Precision Optics

High speed fiber collimator: the performance core of optical communication networks

Fiber optic collimators convert scattered light into collimated beams through precise coupling between lenses and fibers, significantly improving the signal transmission efficiency and stability of optical communication networks. 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 bandwidth scenarios such as 5G base stations and data centers, this design can reduce optical path offset, improve network throughput, and support single-mode (1310nm/1550nm) and multi-mode (850nm/1300nm) wavelengths, adapting to WDM wavelength division multiplexing systems.

High quality fiber collimator: the key to improving the reliability of fiber optic networks

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 a transmittance of over 90%. For example, in complex optical paths such as industrial automation and rail transit, this design can simultaneously process multiple signals, avoid wavelength cross interference, and support multi fiber core options (single fiber/dual fiber/quad fiber), meeting diverse needs from home broadband to industrial grade networks. Its high return loss characteristic can also reduce reflected light interference, ensure signal integrity, and is suitable for high bandwidth, low latency optical communication networks.

Meeting the testing needs of various fiber optic systems: flexible application of fiber optic collimators

The fiber collimator supports single-mode and multi-mode wavelengths and can be adapted to WDM wavelength division multiplexing systems through a wide passband AR film design (bandwidth covering the C-band). For example, in scientific research experiments, this design can simultaneously process multiple signals, avoid wavelength cross interference, and support multi fiber core options (single fiber/dual fiber/quad fiber), meeting diverse needs from home broadband to industrial grade networks. Its high return loss characteristic can also reduce reflected light interference, ensure signal integrity, and is suitable for high bandwidth, low latency optical communication networks.

High stability fiber collimator: a reliable guarantee for aerospace applications

The fiber collimator adopts a tight fitting fiber package (outer diameter 0.9mm/2.0mm) integrated with a micro lens (diameter 1mm-2mm), reducing the volume by more than 50% compared to traditional structures, while maintaining anti vibration performance (mechanical stability up to 0.01mrad). For example, in space constrained applications such as drone obstacle avoidance systems and satellite communication, this design can be embedded with narrow optical path modules while ensuring stable operation at extreme temperatures (-40 ℃ to+85 ℃). Its compactness also simplifies the installation process, making it suitable for scenarios such as aerospace and portable medical equipment that require strict volume and stability requirements.
