Types of Fiber Splitters

Updated on Sun Aug 24 2025

A fiber optic splitter is a fiber optic passive device that splits/combines optical signals, and generally separates or combines optical signals of the same wavelength. According to the different arrangement of fiber optic splitter ports, it can be divided into symmetrical star splitter and asymmetrical tree splitter; according to the type of fiber, it can be divided into single-mode fiber splitter and multi-mode fiber splitter; According to the bandwidth, it can be divided into narrowband fiber optic splitter and broadband fiber optic splitter. According to the production method, the common ones are fused tapered (FBT) splitters and planar light guide (PLC) splitters.


Types of Fiber Splitters

1. Common packaging forms of fiber optic splitter products:

1. Modular encapsulation The usual modular encapsulation forms of FBT and PLC splitters are:

2. Rack Mount Package


Rack-mount packaging usually has the following methods:

3. Tray packaging

Fiber Splitters

3. Handling of common problems:

A certain channel or all channels at the output end are abnormal. This is the most common problem. Usually, the splitter part is less likely to be defective, and it is mainly concentrated on the connector part, and the connector is mainly concentrated on the fiber end face. The general processing methods at the production site are: Use a special wipe stick dipped in alcohol to clean the end faces of the sleeve and the internal connector. Also clean the connectors of the test leads and test again.


After passing the test, install the cleaned dust cap on the adapter. Plug the spare channels or unused channel holes on the rack or tray with silicone plugs or adapters to prevent dust from entering.


General technical indicators of fiber optic splitter:

Identification of fiber optic splitter (connector type) connectors:

(1) FC type fiber optic connector: circular, metal material, screw-in method, usually FC/PC and FC/APC type.

(2) SC fiber optic connector type: square, plastic material, plug-in fixing method, usually SC/PC and SC/APC types.

(3) ST type fiber optic connector type: circular, metal material, bayonet type fixing method, usually ST/PC type.

(4) LC type fiber optic connector: square, plastic material, plug-in fixing method, usually LC/PC and LC/APC types.

(5) MU-type optical fiber connector: square, plastic material, plug-in fixing method, usually MU/PC type.

(6) MT-RJ type optical fiber connector: square, plastic material, plug-in fixing method, usually MT-RJ type.
