Miniature monomode coupler

1. Single-Mode Fiber (SMF): Single-mode optical fibers have a small core diameter, typically around 9 micrometers, which allows them to support only a single optical mode (or path). This characteristic enables them to transmit light signals over long distances with minimal signal dispersion and low loss, making them ideal for high-speed and long-distance optical communication.
2. Coupling: A monomode coupler is used to couple or transfer optical signals between two or more single-mode optical fibers. It can combine multiple input signals into one output fiber (combiner) or split an input signal into multiple output fibers (splitter).
3. Low Insertion Loss: High-quality miniature monomode couplers are designed to minimize signal loss during the coupling process, ensuring efficient signal transfer.
4. Low Cross-Talk: Cross-talk refers to the unwanted transfer of optical signals between input and output ports. Miniature monomode couplers are engineered to have low cross-talk levels to maintain signal integrity.
5. Compact Size: These couplers are often designed to be compact and space-efficient, making them suitable for use in various optical devices and systems where space is limited.
6. Wavelength Dependence: The performance of a monomode coupler can be wavelength-dependent. Some couplers are optimized for specific wavelength ranges, while others may operate across a broader spectrum. It's important to choose a coupler that matches the wavelength of the optical signals in your application.
