Dual Fiber Collimator (GK-C Series)

A Dual Fiber Collimator is a type of fiber optic component that can convert divergent light output from an optical fiber into parallel beams or couple parallel beams back into the fiber. This type of collimator is commonly used in fiber optic systems, such as isolators and DWDM (Dense Wavelength Division Multiplexing) equipment, as a basic building block.

The GK-C series dual fiber collimator is an optical component designed to provide high-performance integration for fiber optic systems. These collimators are constructed using high-quality SMF-28 fibers, ensuring low insertion loss and excellent return loss, which is crucial for maintaining signal integrity in high-performance optical networks

Some key characteristics of GK-C series dual fiber collimator

The typical insertion loss of this collimator is very low, typically between 0.2 and 0.3 dB, which helps reduce signal loss during transmission and improve system efficiency.

The return loss is usually above 60 dB, which helps reduce the optical signal reflected back to the light source, lower noise, and improve system performance.

Whether used for transmission or reflection collimators, the GK-C series provides excellent optical performance and is suitable for applications such as fiber slip rings, circulators, optical switches, collimator arrays, etc.

The collimator is designed to cover multiple operating wavelengths, including 850 nm, 980 nm, 1064 nm, 1310 nm, and 1550 nm, enabling it to adapt to different communication windows.
