Optical splitter (often called fiber optic splitter or optical splitter) is a key component in fiber optic communications. It can split an optical signal into multiple optical signals or combine multiple optical signals into one optical signal. The following are the main functions and applications of optical splitters:


1. Signal splitting:

The most basic function of an optical splitter is to evenly split an incident optical signal into multiple optical signals. This is useful in several applications, such as in Passive Optical Networks (PONs, such as GPON or EPON), where optical splitters enable a single fiber optic line to serve multiple users.


2. Network expansion:

 In optical fiber communication networks, by using optical splitters, the coverage of the network can be expanded, allowing more users or devices to connect to the network.


3. Signal combining:

 In addition to the splitting function, optical splitters can also be used to combine multiple optical signals into one optical fiber.


4. Network monitoring and testing:

 Optical splitters can be used as test points, allowing operators to extract a small portion of the signal from the main line for network monitoring and troubleshooting without interfering with the main signal flow.


5. Increase redundancy:

In some network designs, optical splitters can be used to create redundant paths, ensuring that if one path fails, data can still be transmitted through other paths.


6. Cost Effectiveness:

By using optical splitters, operators can utilize their fiber assets more efficiently, thereby reducing the cost of connection per user or device.


7. Passive devices:

 Most optical splitters are passive, meaning they do not require power or complex management. This reduces the need for maintenance and increases network reliability.


Optical splitters are an essential component in fiber optic communications networks. They provide a simple, reliable and cost-effective method for splitting or combining optical signals, making network design, expansion and maintenance more flexible and efficient.

Optical splitters (Optical Splitter) can be classified into multiple types based on their design and principles. Here are some common types of optical splitters:


1. Fused Biconical Taper (FBT) based on fused taper technology:

    – This type of splitter is created by placing two or more optical fibers closely together and heating them while stretching them so that they fuse together over a length.

    – Due to the fusion process, light entering from one fiber can partially enter another fiber.

    – FBT is an older technology and usually works in 1×2 or 1×4 configurations.


2. Planar waveguide optical splitter (PLC Splitter):

    – PLC splitters use miniature optical waveguide chip technology to distribute light to multiple outputs.

    – They can provide more split ratios in smaller packages, such as 1×8, 1×16, 1×32 or more.

    – PLC splitter provides better uniformity and stability.


3. Wavelength sensitive splitter:

    – This type of splitter splits or combines optical signals based on their wavelength.

    – They are often used in DWDM or CWDM systems to provide routing for signals of specific wavelengths.


4. Mode Field Distribution (MFD) splitter:

    – Splitting by utilizing different modes of light, especially suitable for multimode fiber applications.


5. Other types:

    – Such as tree and star splitters: these are described according to their network topology and can use FBT or PLC technology.

    – Micro-optical component splitters: These are implemented using micro-optical technologies such as micro-lenses, micro-reflectors, etc.


When selecting an optical splitter, factors such as the specific needs of the application, expected split ratio, loss requirements, packaging type, and cost need to be considered.

OSU is often used to refer to “Optical Splitter Unit”, which is a component in optical fiber communications. OSU optical splitter board mainly refers to an optical splitter unit integrated in a fixed board or module. It is usually used in optical fiber access networks, such as passive optical networks (PON). Optical splitters in this board are used to split incoming optical signals so that they can serve multiple downstream users or devices.


For example, in a GPON (Gigabit Passive Optical Network) or EPON (Ethernet Passive Optical Network) system, OSU optical splitter board can be used to split the signal from an OLT (Optical Terminal) to multiple ONTs (Optical Network Terminal) ) or ONUs (Optical Network Units).


This integrated design makes the network layout simpler and allows for more effective management and maintenance in a centralized location. In addition, integrating optical splitters into the board also helps improve overall system reliability and stability.


OSU (Optical Splitter Unit) optical splitter board is mainly used in passive optical fiber access networks in optical communications, especially in PON (Passive Optical Network) technology, such as GPON, EPON and other related technologies. The following are the main applications of OSU optical splitter boards in optical communications:


1. Split optical signals:

 The core function of the OSU optical splitter board is to split a single optical signal from upstream (such as OLT) into multiple downstream signals to supply multiple users or devices (such as ONUs or ONTs).


2. Improved network efficiency:

 By using integrated optical splitter boards, service providers can serve large numbers of users more efficiently without having to deploy separate optical fibers for each user.


3. Simplified network deployment:

The integrated optical splitter board simplifies the physical layout of the network and reduces the number of components, thereby simplifying deployment and maintenance.


4. Cost savings:

Compared with independent optical splitters and other network components, integrated OSU optical splitter boards may provide better economic benefits, especially in large-scale deployments.


5. Network reliability and stability:

 The integrated design reduces connection points and potential failure points, thereby improving the overall reliability and stability of the network.


6. Flexibility and scalability:

As the number of users and data needs grow, the OSU optical splitter board provides a flexible and scalable solution that can easily add more users or provide higher bandwidth .


In the field of optical communications, OSU optical splitter boards are key components in PON technology and other optical fiber access technologies. As broadband demand continues to grow, this type of technology and its related components will continue to be widely used around the world.

In optical communication solutions, OSU (Optical Splitter Unit) optical splitter boards are usually used in passive optical fiber access networks, especially in PON (Passive Optical Network) technology, such as GPON, EPON, etc. The following are typical steps for using the OSU optical splitter board:

1. Network design stage:

 In the early stage of designing the entire optical fiber access network, decide how many OSU optical splitter boards are needed as well as their size and performance based on the expected number of users and geographical distribution.

2. Installation and deployment:

In the physical network deployment stage, the OSU optical splitter board is installed in a specific location, such as an equipment room, street cabinet, or other appropriate location.

3. Signal distribution:

In the network, the optical signal emitted from the OLT (Optical Terminal) is split through the OSU optical splitter board. These split signals are then distributed to multiple ONTs (Optical Network Terminals) or ONUs (Optical Network Units).

4. Monitoring and maintenance:

 To ensure the normal operation and high reliability of the network, the OSU optical splitter board needs to be monitored and maintained regularly. This step may include physical inspection of the board, performance testing, and troubleshooting.

5. Network upgrade or expansion:

Over time, if the number of users increases or bandwidth requirements increase, more OSU optical splitter boards may need to be replaced or added to meet these new requirements.

In optical communication solutions, OSU optical splitter boards play a core role, especially in passive optical fiber access networks. It provides the possibility for multiple users to share a single upstream fiber connection, thereby reducing costs and improving network scalability.
