Splitters
Splitter is a networking device that is used to split a single input signal into multiple output signals. It is a passive device that does not require any external power source to operate. The main purpose of a splitter is to divide the signal strength into equal parts to be transmitted over multiple lines or to multiple devices. By using a splitter, multiple devices can access the same network connection using a single input.
Advantages of Splitters
Accurate positioning
When dividing or stopping, the divider can ensure that the liquid sub precision axis is fixed in the set position without the need for additional locking components, improving the accuracy and reliability of the operation.
Smooth transmission
Due to the design of the output tower, which can rotate continuously at any position, and the smooth operation of the transmission device without vibration and noise, this helps to improve overall work efficiency and equipment life.
High segmentation accuracy
Through specially designed cam rollers, the cam divider can maintain a high segmentation accuracy, usually up to ± 30 seconds, and can be customized with higher precision products according to needs, such as ± 15 seconds.
High speed performance
Applying preloading load on the tapered support ribs of precision machined cams and cam rollers completely avoids the generation of gaps, thereby improving stability and load capacity during high-speed operation.

How to Ensure the Precise Alignment and Stability of the Distributor
Cleaning and preparation
First, the waveguide and fiber must be thoroughly cleaned to remove any dust or contaminants. Then, the waveguide is mounted on the waveguide frame, one end of the fiber is mounted on the precision adjustment frame at the incident end, and the other end is connected to the light source (such as a 6.328 micron red light source) for observation during the initial commissioning of the optical machine.
Machine vision and hybrid automatic alignment algorithm
The method of combining machine vision technology with hybrid automatic alignment algorithm achieves high-precision alignment, ensuring that the additional alignment loss of the waveguide device is less than 0.15DB.
Precision adjustment frame
The position of the waveguide and fiber is fine-tuned using a precision adjustment frame to ensure that they remain optimally aligned during the coupling process.
Interferometry
Interferometry can be used to verify that the correct alignment has been achieved. Dynamic interferometry can provide real-time system alignment information to ensure stability during the alignment process.
Packaging unit
The packaging unit usually contains technologies such as UV glue or YAG laser welding to ensure the stability and long-term reliability of the waveguide and fiber during the packaging process.
Temperature stability
The splitter should have good temperature stability, with wavelength-dependent loss and 0.3dB temperature stability in the temperature range of -40 to 85°C.
Multi-fiber alignment technology
For polarization-maintaining splitters, precise multi-fiber alignment technology can be used to bond the optical fiber to the PLC circuit chip, which can maintain low insertion loss and high polarization extinction ratio over a wide wavelength range.
Process of Splitters
Component preparation
The main components of the splitters are the input and output fiber arrays and the chip. The design and assembly of these components are key to producing high-quality PLC splitters. The PLC circuit chip is embedded on a glass wafer, and each end of the glass wafer is polished to ensure high precision and purity of the surface. V-grooves are then ground into the glass substrate. Single optical fibers or multiple ribbon fibers are assembled onto the glass substrate. The assembly is then polished.
Alignment
After the three components are prepared, they are placed on the aligner table. The input and output fiber arrays are placed on the goniometer table and aligned with the PLC chip. The physical alignment between the fiber array and the chip is monitored by the continuous power level output by the fiber array.
Curing
The assembly is then placed in a UV (ultraviolet) chamber for full curing at a controlled temperature.
Packaging
The bare optical splitter is aligned and assembled into a metal housing, and fiber sleeves are set at both ends of the assembly. Temperature cycling testing is then required to ensure the final product status.
Optical testing
In terms of testing, the three important parameters of the optical splitter are tested: insertion loss, uniformity, and polarization-dependent loss (PDL) to ensure that the optical parameters of the manufactured optical splitter meet the GR-1209 CORE specification.
How to Choose a Splitters
Network size and type
Consider the size and type of the network where the splitter will be deployed. For larger networks, planar lightwave circuit splitters are often preferred due to their scalability, wider bandwidth, and higher splitting ratios. Smaller networks may benefit from fused biconical tapered splitters, which are more cost-effective for lower splitting ratios.
Signal requirements
Evaluate the signal requirements of the network. If the application demands high data rates, low latency, and minimal signal loss, choose splitters with low insertion loss and high return loss. splitters generally offer better performance in terms of insertion loss and return loss compared to splitters.
Performance and cost comparison
Splitters are typically more cost-effective for smaller networks and lower splitting ratios. splitters, although relatively more expensive, offer better performance, wider bandwidth, and higher splitting ratios, making them suitable for most fiber optic networks or applications requiring greater signal distribution capacity.
Splitter configuration
Determine the appropriate splitter configuration based on the number of output ports required. Common configurations include 1×2, 1×4, 1×8, and so on, representing the number of input and output ports. Evaluate the current and future network requirements to select the optimal splitter configuration.
Wavelength compatibility
Consider the wavelength compatibility of the splitter with the optical signals used in the network. Ensure that the chosen splitter supports the specific wavelengths required for the application. Some splitters may be wavelength-dependent, and selecting the appropriate type ensures compatibility and optimal performance.
Quality and reliability
Select optical splitters from reputable manufacturers known for their quality and reliability. This ensures that the splitters meet industry standards and provide consistent performance over time. Consider factors such as durability, environmental stability, and long-term reliability when making a selection.
Input signal reception
The splitter receives an optical signal through its input port. A single fiber optic cable typically carries this signal and contains data transmitted as light pulses.
Signal splitting
Inside the splitter, the light signal encounters a splitting mechanism. Depending on the type of splitter (such as fused biconical taper or planar lightwave circuit), this mechanism may involve the physical splitting of the fiber or a specialized optical waveguide circuit.
Distribution of signal
The splitter then divides this incoming light signal into multiple outputs. Depending on the splitter's design, the division can be equal (such as 50/50 in a two-way splitter) or in other ratios. This process is achieved purely in the optical domain, meaning the light is not converted to electrical signals at any point.
Transmission to multiple outputs
The split signals are transmitted through the splitter's multiple output ports. Each output port carries a fraction of the original signal's power, allowing the signal to be distributed to different locations or devices in the network.
Maintaining signal integrity
While there is some inherent loss of signal strength due to splitting, high-quality splitters are designed to minimize this loss, ensuring that the distributed signals remain strong enough for effective transmission and reception.
