The steel-tube planar waveguide optical splitter (PLC splitter) is a micro spltiter fiber optic packaged in a stainless steel tube. The internal coupling section can be connected to various fiber optic connectors for termination or without connectors for fusion splicing. Its compact size, high reliability, and flexible installation make it the most widely used fiber optic splitter on the market.

Advantages of Micro Splitter Fiber Optic
- Miniature design: Easily installs in space-constrained environments, such as small fiber distribution boxes or junction boxes.
- Wide operating wavelength range (1260-1650nm): Supports multiple wavelengths (such as EPON’s 1310nm, 1490nm, and 1550nm), adapting to various network requirements.
- High reliability and environmental stability: Suitable for outdoor deployment or harsh environments, such as those with high temperature, high humidity, or vibration.
Main Application of Micro Splitter Fiber Optic
1. Fiber to the Home (FTTH):
In FTTH networks, fiber optic tube splitters are widely used in corridors, optical distribution boxes, or fiber splice boxes to distribute optical signals from the central office (OLT) to multiple user terminals (ONUs/ONTs), achieving efficient fiber-to-the-home (FTTH) distribution.
2. Passive Optical Network (PON):
Applicable to passive optical networks such as EPON, GPON, and BPON, connecting central office equipment and terminal devices, ensuring uniform distribution of optical signals and meeting broadband access requirements.
3. Fiber Optic Splice Closures and Distribution Boxes:
Steel tube splitters, due to their compact structure, are often installed in fiber optic splice closures, module boxes, or distribution boxes. They are suitable for fixed installations where they are not frequently disassembled, providing stable optical signal distribution.
4. Data Center and Local Area Network (LAN):
In data centers or LANs, they are used to split and combine optical signals, supporting high-density cabling and high-speed data transmission.
5. Cable Television (CATV) Systems:
They are used to distribute optical signals within CATV networks, ensuring even signal transmission to multiple users.
6. Fiber Optic Sensors and Test Equipment:
In fiber optic sensor systems or test scenarios, steel tube splitters are used to split optical signals to meet multi-channel testing requirements.
Highly Customizable for Micro Splitter Fiber Optic

Steel Tube Dimension
Steel Tube Dimensions: For example, for fiber optic tube splitter within 8 chanels, the standard tube size is 60*7*4mm, but this can be changed into 50*7*4mm as well.

Fiber Splitter Pitch
250µm or 125µm, depending on the fiber arrangement.

Fiber Tubing Color
Customizable for both inlet and outlet ends, such as blue, white, red, or black for the inlet; white with numbered tubing, color, or custom color for the outlet.

Custom Stickers
Test report or the steel tube surface can paste stickers with logo, serial number, and description, on customer request

Fiber Cable Type
Single-mode fiber splitters are commonly used; multimode splitters are rarely used. Commonly used fibers include G.652D, G65A71, G657A2, and G657B3. Fiber lengths range from 0.3m to 1.5m.

Fiber Optic Connectors
Cutoms SC, LC, FC, ST, MPO/MTP connectors with UPC or APC polishing, simplex or duplex
Conclusion
In addition to micro splitters, Yingda can pack fiber optic splitters in different packaging methods: bare fiber splitters, plc splitter module, PLC ABS splitter, rack mount plc splitter, integrated splice tray cassette splitter, etc., which are suitable for more complex installation environments.

Micro Splitter Fiber Optic FAQ
- Can you do 1×128 splitter in micro splitter?
Yes, Yingda can do 1×128 splitter with steel tube. Please contact salesperson for details.

- 2. Can you add 2 pcs plc splitter in a cassette module?
Yes, we can use ABS to hold 2pcs steel tube together, any splitting ratio can do: 1*2, 1*4, 1*8, 1*16, 1*32 ,etc

- 3. How do you pack the micro splitter?
Yingda offer invidvidual blister box for each piece of micro splitters, with better protection. And in order to avoid the loose during transporation, we upgrade the V-groove design on the edge and internal structure of the plastic shell, which can hold the splitter in place.
