Fiber optic splitter is a device used in fiber optic networks to split an optical signal into multiple signals, or combine multiple signals into one.  It's commonly used in Passive Optical Networks (PONs), where a single optical fiber is split to serve multiple users or destinations.

There are two main types of fiber optic splitters:

Fused Biconical Taper (FBT) Splitters: These splitters are made by heating and stretching (or tapering) a pair of fibers together, causing them to fuse and create a splitter.  The ratio of the splitting is determined by the length of the fused region and the refractive index of the materials involved.

Planar Lightwave Circuit (PLC) Splitters: PLC splitters are fabricated using semiconductor manufacturing techniques on a silica glass substrate.  They offer advantages such as low insertion loss, uniform splitting ratios, and a compact size.  PLC splitters are generally preferred for high-density applications and where precise splitting ratios are required.

Fiber optic splitters come in various split ratios, such as 1:2, 1:4, 1:8, etc., indicating how many output ports the splitter has and what portion of the signal each output port receives.

These splitters play a crucial role in distributing optical signals efficiently in telecommunications, fiber-to-the-home (FTTH) networks, cable television (CATV) systems, and other fiber optic communication systems.

The price of fiber optic splitters can vary depending on several factors, including the type of splitter (FBT or PLC), the split ratio, the number of ports, the quality of construction, the brand, and the quantity being purchased. Here are some general price ranges:

FBT Splitters:

Prices for FBT splitters typically range from a few dollars for simple, low split ratio splitters to several hundred dollars for more complex and higher split ratio devices.

For example, a basic 1x2 FBT splitter might cost around $5 to $10, while a 1x32 FBT splitter could cost $50 to $100 or more.

PLC Splitters:

PLC splitters tend to be more expensive than FBT splitters due to their manufacturing process and performance advantages.

Prices for PLC splitters can range from around $10 to $100 or more, depending on factors such as the split ratio and number of ports.

For instance, a 1x8 PLC splitter might cost around $20 to $30, while a 1x32 PLC splitter could cost $50 to $100 or more.

It's important to note that these are general price ranges, and actual prices may vary based on factors such as supplier, region, and specific product specifications. Additionally, bulk purchasing may result in discounts or lower per-unit prices. For precise pricing information, it's best to consult with fiber optic equipment suppliers or distributors.
