Optical splitters are available in various types, including PLC, FBT, multimode, and optical audio splitters, with multiple split ratios, configurations, and connector options.

Fiber Optic Splitters

PLC (Planar Lightwave Circuit) Splitters use a micro-optical chip to divide a single input signal into multiple outputs with high uniformity and reliability. They are ideal for large split counts such as 1×16, 1×32, or 1×64, commonly used in FTTx and PON networks . PLC splitters are compact, stable across temperature ranges, and provide low insertion loss. FBT (Fused Biconical Taper) Splitters are a traditional technology where fibers are fused and tapered together. They are suitable for smaller split counts like 1×2, 1×4, or 1×8 and are cost-effective for simpler network deployments . Multimode Fiber Splitters (MFS) are designed for multimode signals, typically with core diameters from 50 to 400 µm. They can operate in 1×N splitter or NxN combiner configurations, providing uniform splitting ratios and low insertion loss for applications such as sensing, optogenetics, and fluorescence detection .

Optical Audio Splitters

Optical audio splitters, often using Toslink or SPDIF interfaces, allow a single digital audio source to feed multiple output devices. They support uncompressed PCM, Dolby Digital, DTS-HD, and other formats, and are commonly used in home theater systems, soundbars, and receivers .

Packaging and Connector Options

Optical splitters are available in various packaging types:

• ABS Box, LGX Cassette, Rack-Mount Modules for fiber networks .
• Cassette, Tray, and Rack Panel Splitters for PON networks, offering protection and easy installation .
• Bare or Connectorized Splitters for inside plant (ISP) or outside plant (OSP) applications . Connectors can include SC, LC, FC, or customized options depending on network requirements .

Split Ratios and Configurations

Splitters are available in multiple ratios to distribute optical signals efficiently:

• 1×2, 1×4, 1×8, 1×16, 1×32, 2×32 for fiber networks .
• 1×N or NxN for multimode splitters .
• Audio splitters typically split one input to two outputs or more, depending on the model .

Summary

Optical splitters come in a wide range of technologies, split ratios, packaging, and connector types to suit different applications, from high-capacity fiber networks to home audio systems. PLC splitters are preferred for high-count, high-stability applications, FBT for simpler networks, multimode splitters for specialized light management, and optical audio splitters for digital sound distribution.
