What is Optical Splitter Fiber?

Posted by

Optical Splitter Fiber, also referred to as Fiber optic splitter, fiber splitter or beam splitter, is an integrated waveguide optical power distribution device that can split an incident light beam into two or more light beams, and vice versa.

different types of Optical Splitter Fiber

Optical Splitter Fiber is one of the most important fiber optic components in passive fiber network even in outside plants cablings.When you source an Optical Splitter Fiber, You should have basic understanding about it. Here below you can have grasp the main points for Optical Splitter Fiber.

What is Optical Splitter Fiber?

An Optical Splitter Fiber, integral in fiber optic networks, is a device that divides the light signal from a single optical fiber into multiple fibers, distributing the signal to different destinations. This device is crucial in passive optical networks (PONs), such as those used for telecommunications and cable TV, allowing a single fiber optic connection to serve multiple premises.

How does a fiber optic splitter work?

fiber optic splitter work

A fiber optic splitter works by taking a single optical input and dividing it into multiple outputs, without necessitating an external power source.

In FBT splitters, the optical fibers are fused together, and the light is split between these fibers based on the physical properties of the fibers themselves.

In PLC splitters, the optical signal is divided using a photolithographic technique to create a series of waveguides that precisely direct the signals to multiple outputs. This process allows for a consistent and predictable distribution of optical signals.

Types of Optical Splitter Fiber

In todays fiber networks, There are mainly 2 types of Optical Splitter Fiber in the market, namely FBT splitter and PLC splitter.

Fused Biconical Taper (FBT) Splitter

This type of splitter is made by twisting and heating two or more fibers together, and then pulling them to form a biconical shape. The ratio of the split can be adjusted by changing the pull length and angle.

Planar Lightwave Circuit (PLC) Splitter

PLC splitters use a micro-optical integration technology to distribute light from a single fiber to multiple fibers. They are manufactured using silica optical waveguide technology to create a precise splitting ratio.

How to choose the right Optical Splitter Fiber for your project?

  1. Splitting Needs: Consider whether you need a precise split ratio. PLC splitters offer more uniformity and can support more outputs.
  2. Budget: FBT splitters are generally more cost-effective, especially for smaller, less complex projects.
  3. Operating Environment: If the splitter will be exposed to varying temperatures or harsh conditions, a PLC splitter’s stability might be advantageous.
  4. Wavelength Requirements: For systems that require a wide range of wavelengths, PLC splitters are more suitable due to their broader operating wavelength range.

What is the Optical Splitter Fiber Loss you need to know?

Optical loss refers to the reduction in power of the light signal as it splits and travels through the fiber. It’s measured in decibels (dB). Both FBT and PLC splitters introduce some level of insertion loss, with the specific amount depending on the split ratio, type of splitter, and quality of the manufacturing. Understanding the loss your network can tolerate is crucial in selecting the right splitter. to see the fiber splitter loss chart you will know the standard datasheet for the Insertion loss and return loss.

What is the application of Optical Splitter Fiber?

Most of time, Optical Fiber Splitters are used in wall mount fiber distribution box, fiber termination box from user end, or fiber patch panel at data center, or splitter type fiber enclosures, They should be well protected inside the enclosures. You can wholesale Optical Fiber Splitters with connectors to connect fiber pigtails directly, or Optical Fiber Splitters without connectors to splice with pigtails or fiber cables directly.

Application of Optical Splitter Fiber

Optical splitters are used in various applications including:

  • Fiber to the Home (FTTH) networks
  • Cable TV (CATV) systems
  • Local Area Networks (LANs)
  • Telecommunications
  • Data processing networks
