Splitters
A PLC (Planar Lightwave Circuit) splitter is a passive optical component used in fiber optic networks to split or combine optical signals. It is commonly used in applications such as passive optical networks (PONs), fiber-to-the-home (FTTH) networks, and other optical communication systems. PLC splitters offer several advantages, including high splitting ratios, low insertion loss, and a compact design.
PLC splitters play a crucial role in optical network infrastructure by enabling efficient signal distribution and communication. Their passive and durable nature makes them an essential component in many optical communication applications.
Basic Functionality: PLC splitters are designed to divide an incoming optical signal from a single input fiber into multiple output fibers or to combine signals from multiple input fibers into a single output fiber. They perform this function passively, without the need for power or electronics.
Splitting Ratios: PLC splitters come in various splitting ratios, such as 1x2, 1x4, 1x8, 1x16, 1x32, and more. The first number denotes the number of input ports, and the second number indicates the number of output ports. For example, a 1x4 PLC splitter takes one input and divides it into four outputs.
Low Insertion Loss: PLC splitters are known for their low insertion loss, which means that they minimize the reduction in signal strength as the light passes through the splitter. This is essential for maintaining signal quality in optical networks.
Uniform Splitting: PLC splitters provide uniform splitting, ensuring that each output port receives an equal share of the input signal's power. This uniformity is critical for reliable signal distribution.
Wavelength Insensitivity: PLC splitters are typically wavelength-insensitive, meaning they can work with a wide range of optical wavelengths without significant performance degradation. This makes them suitable for various applications in multi-wavelength optical systems.
Compact Design: PLC splitters are designed using semiconductor-based planar lightwave circuit technology, which allows for a compact and robust design. This compact form factor is especially valuable in space-constrained environments.
Temperature and Environment Tolerance: PLC splitters are often designed to operate over a wide temperature range and are built to withstand environmental conditions in outdoor and indoor settings.
Applications: PLC splitters find applications in various optical communication systems, including PONs, FTTH networks, CATV (Cable Television), and data center networks. They are used for splitting, distributing, and combining optical signals efficiently.
Types: There are various types of PLC splitters, including bare fiber PLC splitters and module-based PLC splitters. Module-based PLC splitters are typically easier to install and maintain.
Customization: PLC splitters can be customized to meet specific requirements, including unique splitting ratios or packaging for different installation scenarios.
Reliability: PLC splitters are known for their reliability and long service life, making them a preferred choice in optical networks.
