product description
The GKER Photonics 2 µm Polarization Maintaining Tap Coupler (GK-PMTC Series) is a state-of-the-art optical component engineered for precision light management at a wavelength of 2000 nm. Designed with advanced technology, this coupler provides high-performance light splitting with minimal signal degradation. It allows for fine-tuning of tap ratios, including 1%, 2%, 4%, 5%, 10%, 20%, and 50%, making it versatile for various applications requiring precise optical monitoring.
This coupler excels in maintaining polarization integrity, crucial for systems where polarization-dependent effects can impact performance. The device features exceptionally low excess loss and high return loss, ensuring effective signal transmission and minimal interference. Its high extinction ratio guarantees that the split light remains consistent and stable, meeting the demands of high-precision applications.
The GK-PMTC Series coupler supports a maximum optical power of 300 mW and is built to handle high tensile loads, making it suitable for high-power fiber laser systems and other robust optical environments. Its environmental stability is notable, with reliable operation across a broad temperature range from -5°C to +70°C, and it can withstand storage temperatures up to +85°C.
Constructed with either PM 1550 Panda fiber for input and output ports or SMF-28 for tap ports, this coupler ensures superior performance and durability. Its design includes features to minimize polarization mode dispersion, enhancing overall system efficiency. This coupler is ideal for use in sophisticated optical systems where high precision and reliability are paramount, such as in advanced telecommunications, high-power fiber lasers, and scientific research applications.
