1310-1550nm Singlemode Broadband Coupler -SBC
Description
The GKER Photonics Singlemode Broadband Coupler (GK-SBC Series) is an advanced optical component meticulously engineered to meet the rigorous demands of modern optical communication systems. This series of couplers is characterized by its exceptional performance in terms of low insertion loss, low polarization dependence, and unparalleled environmental stability. These features make the GK-SBC Series a reliable and efficient solution for a wide range of applications where signal integrity and consistency are paramount.
At the core of the GK-SBC Series is its ability to provide precise and consistent power splitting across a broad wavelength range, centered around the industry-standard wavelengths of 1310 nm and 1550 nm. The couplers are designed to handle coupling ratios from as balanced as 50/50 to as selective as 1/99, ensuring that users can achieve the exact optical power distribution needed for their specific application. This flexibility is crucial in complex optical networks where different components require different power levels for optimal operation.
One of the standout features of the GK-SBC Series is its low insertion loss, which ensures that the signal degradation during splitting is kept to an absolute minimum. This is particularly important in long-haul communication systems where maintaining signal strength is critical. Additionally, the low polarization dependence ensures that the coupler performs consistently regardless of the polarization state of the incoming signal, which is essential for maintaining signal quality in varying environmental conditions.
Environmental stability is another key advantage of the GK-SBC Series. These couplers are designed to operate reliably in a wide temperature range, from -5°C to +70°C, making them suitable for use in diverse and challenging environments. Whether installed in a temperature-controlled data center or deployed in an outdoor telecom infrastructure, the GK-SBC couplers will deliver consistent performance.
Moreover, the high return loss and directivity of these couplers minimize back reflections and cross-talk, further preserving the integrity of the optical signals. This is particularly beneficial in dense network environments, such as data centers and telecom hubs, where multiple signals are transmitted simultaneously.
The GK-SBC Series is also highly customizable, with options for different fiber types, connector types, and fiber lengths, allowing users to tailor the product to their exact needs. Whether you require a 250 µm bare fiber, a 900 µm loose tube, or a 3 mm cable, GKER Photonics offers a configuration that will integrate seamlessly into your existing setup.
In summary, the GKER Photonics Singlemode Broadband Coupler (GK-SBC Series) is a versatile, high-performance component that meets the demands of today’s optical communication systems. Its low insertion loss, wide range of coupling ratios, low polarization dependence, and robust environmental stability make it an indispensable tool for ensuring reliable and efficient signal transmission across various applications, from telecom networks to data centers and fiber optic sensors.
