Ultra Low Ratio Tap Coupler-LTC
Description
The GK-LTC Series Ultra Low Ratio Tap Coupler is designed to offer exceptional performance in scenarios where monitoring of high-power optical signals is crucial. With tap ratios as low as 0.1%, 0.01%, and 0.001%, this coupler enables precise sampling of light while preventing damage or saturation of sensitive photodetectors. It is particularly suited for applications involving high optical power, such as fiber laser monitoring, EDFA (Erbium-Doped Fiber Amplifier) systems, and DWDM (Dense Wavelength Division Multiplexing) systems.
This coupler features a low tap insertion loss of 30 ± 3 dB, ensuring minimal signal disruption while diverting a very small fraction of light to the tap port. The signal insertion loss is also remarkably low at just 0.1 dB, maintaining high signal integrity. Its thermal stability is excellent, with a variation of ≤ 0.002 dB/°C, allowing it to perform reliably across a broad temperature range from -40°C to +105°C.
The GK-LTC Series supports high average optical power up to 3 W and peak power for nanosecond pulses up to 10 kW, making it an ideal choice for environments with demanding power requirements. The coupler's robust design ensures consistent performance and durability, making it a valuable component in advanced optical communication systems and monitoring applications.
With its high power handling capabilities and precise light extraction, the GK-LTC Series Ultra Low Ratio Tap Coupler provides accurate and reliable monitoring for critical optical applications, ensuring optimal performance and system integrity.

Frequently Asked Questions
The Ultra Low Ratio Tap Coupler is available with coupling ratios as low as 0.001%. This extremely low ratio allows for precise monitoring of high-power optical signals without damaging the photodetector.
The GK-LTC Series can handle a maximum average optical power of up to 3 W. For peak power in nanosecond pulses, it can handle up to 10 kW.
The tap insertion loss for the GK-LTC Series is typically 30 ± 3 dB, which ensures that only a very small fraction of the light is diverted to the tap port.
The coupler exhibits excellent thermal stability with a variation of ≤ 0.002 dB/°C. This ensures reliable performance across a wide temperature range from -40°C to +105°C.
The coupler is designed to work with Corning SMF-28 fiber. Custom fiber types can be specified if needed.
The GK-LTC Series is ideal for high-power optical applications, including monitoring in EDFA (Erbium-Doped Fiber Amplifier) systems, DWDM (Dense Wavelength Division Multiplexing) systems, and vehicle applications where precise light sampling is required.
The standard model is designed for a center wavelength of 1550 nm. Custom wavelengths may be available upon request.
The coupler is available with no connectors (N) as standard. Other connector types can be specified if needed.
The coupler dimensions vary depending on the configuration. For instance, the 1 × 2 configuration has a diameter of Φ3.0 mm and a length of 54 ± 1 mm for 250 μm bare fiber, and Φ4.0 mm with a length of 70 ± 1 mm for 900 μm loose tube.
