A Comprehensive Guide to Fiber Optic Splitters in China
Fiber optic splitters are crucial passive optical components used in fiber optic communication networks. They divide a single optical signal into multiple identical signals, enabling efficient distribution of bandwidth to numerous users or devices. This guide explores the diverse landscape of fiber optic splitters manufactured in China, focusing on their technical features, types, and applications. Several prominent Chinese manufacturers, such as those found at www.shtptelecom.com, www.fiberplcsplitter.com, www.focc-fiber.com, fibreopticbox.com, and www.China-tscom.com, contribute significantly to this market.
Understanding the Technical Features
Fiber optic splitters exhibit key performance characteristics impacting their suitability for specific applications. These characteristics are often determined by the splitter’s design and manufacturing process. Key specifications include insertion loss, return loss, polarization dependent loss (PDL), and operating wavelength range. These parameters influence the signal quality and overall network performance. Lower insertion loss is desirable, minimizing signal attenuation. High return loss prevents signal reflections, ensuring signal integrity. Low PDL is important for maintaining consistent signal quality across different polarization states. The operating wavelength range dictates the compatibility with various light sources and transmission systems.
| Feature | Description |
|---|---|
| Insertion Loss | The reduction in optical power caused by the splitter. Lower is better. |
| Return Loss | The ratio of reflected to incident optical power. Higher is better (indicates less reflection). |
| Polarization Dependent Loss (PDL) | The difference in insertion loss for different polarization states. Lower is better. |
| Operating Wavelength Range | The range of wavelengths the splitter effectively operates within. |
| Splitting Ratio | The ratio of input to output signals (e.g., 1×2, 1×4, 1×8, 1×16, 1×32, 1×64, 2×32). This determines the number of output signals. |
| Connector Type | The type of connectors used on the input and output fibers (e.g., SC, LC, FC, ST, MTP/MPO). |
| Packaging Type | The physical form factor of the splitter (e.g., bare fiber, ABS box, cassette, tray, rack-mounted). |
Different Types of Fiber Optic Splitters
The two primary types of fiber optic splitters are PLC splitters and FBT splitters. PLC (Planar Lightwave Circuit) splitters utilize a silicon-based waveguide structure to divide the optical signal. They offer superior performance characteristics compared to FBT splitters, such as lower PDL and better uniformity across the output ports. FBT (Fused Biconic Taper) splitters, on the other hand, employ a fused fiber structure. They are generally less expensive than PLC splitters but may exhibit higher insertion loss and PDL. The choice between PLC and FBT depends on the specific application requirements and budget constraints. Manufacturers like those on www.fiberplcsplitter.com specialize in producing both types.
| Feature | PLC Splitter | FBT Splitter |
|---|---|---|
| Technology | Planar Lightwave Circuit | Fused Biconic Taper |
| Insertion Loss | Typically lower | Typically higher |
| PDL | Typically lower | Typically higher |
| Cost | Generally higher | Generally lower |
| Splitting Ratio | Wide range, including high split ratios (1×64+) | Limited range, typically lower split ratios |
| Wavelength Range | Wide range (1260-1650nm) | Narrower range |
| Environmental Stability | Generally better | Can be more susceptible to environmental changes |
Companies like FOCC Fiber Co. LTD (www.focc-fiber.com) and T&S Communications Co., Ltd. (www.China-tscom.com) offer a wide range of both PLC and FBT splitters, catering to diverse customer needs. The choice of splitter type often depends on factors such as budget, required performance, and the specific application environment. For instance, high-density data centers often favor PLC splitters for their superior performance.
Applications and Market Trends
Fiber optic splitters find widespread applications in various communication networks. They are essential in FTTH (Fiber To The Home) deployments, enabling service providers to efficiently distribute broadband services to numerous subscribers. They are also used extensively in PON (Passive Optical Network) architectures, forming the core of optical signal distribution. In addition, they play a vital role in CATV (Cable Television) networks and enterprise networks, facilitating efficient signal distribution and bandwidth sharing. The increasing demand for high-bandwidth applications like 5G and cloud computing drives the growth of the fiber optic splitter market in China. Companies like those at fibreopticbox.com highlight the importance of splitters in various applications, including data centers and FTTH networks. Shanghai Tangpin Technology Co., Ltd. (www.shtptelecom.com) also offers splitters as part of their broader product portfolio.
Conclusion
Fiber optic splitters are essential components in modern communication networks. The Chinese market boasts a thriving manufacturing sector offering a wide range of splitters with varying features and performance characteristics. The choice between PLC and FBT splitters depends on application requirements and budget. The ongoing growth in high-bandwidth applications ensures continued demand for these crucial components.
