PTP Switch Buying Guide: Comparison of MOXA, 3onedata & Rayin

There are lots of PTP switch manufacturers in the market, and most of them claim their products are self-developed. Normally it is not hard to choose ordinary industrial switches, but for the rail transit, or high-precision IEEE 1588v2 synchronous PTP switch selection, some special requirement, it becomes hard for R&D and sourcing people. As you know, R&D people always focuses on the PTP protocol compatibility, monitoring and configuration capacity and the reliability of the whole machine, such as wide temperature, anti-seismic property and duplicate power supply. Sourcing people always focus on industry qualification, cost delivery, after-sales and system compatibility, and how to filter good suppliers who have both high quality, good reputation and reliable delivery schedules? In this paper, we will introduce three high quality manufacturers for PTP switch in 2026, they are Moxa, 3onedata and Rayin Technology, and we will introduce their products in detail.

Hereby, Let’s take one model of theirs products, 12-port fully gigabit PTP L2 network managed industrial Ethernet switch, for example to introduce.

 1.The mechanical characteristics comparison:

In general, because the space inside the industrial control cabinet is small, it is always installed by 35mm DIN, and the compact, 10 Gigabit Backbone PTP ethernet switch is more efficient. However, under the passive heat dissipation architecture without fan, the size of the device directly determines the heat dissipation area and the maximum supported power. The size of the device also further limits the PoE output capability and the distribution density of the Gigabit ports. When selecting PTP industrial switches, it is recommended to measure the installation space first, then check the parameters, and when choosing high-power PoE and multi-Gigabit models, you don't necessarily have to choose the larger-sized ones.

2. The exchange parameters comparison:

The MAC address table and packet cache is the key hardware parameter of the industrial switch, which directly affects the network carrying capacity and the stability of the operation. The two must work together to stabilize the data transmission at the scene. If a switch can work properly under high loads, depending on these two hardware capabilities. 

The MAC address table records the correspondence between ports and device addresses. Insufficient capacity can easily lead to broadcast storms and network downtime. Because the industrial equipment is online all the time and the Mac address is updated slowly, the MAC address capacity is recommended to reserve less than 2-3 times of the number of actual  online equipment.

Packet cache is used to buffer burst traffic and adapt to different port rates.  If the cache is too small, it will lose critical business messages; If the cache is too big, it can cause cache accumulation, affecting real-time control and PTP clock synchronization. For the industrial environment it is more recommended for the shared cache design with QOS schedule. For example, whether it is the guide or the network tube switch, all should be based on the scale of the field equipment and the characteristics of the flow, not the multi-size cache specification.

Whether it is for a DIN switch, ptp switch or a manged ptp enabled switch, the selection should be based on the scale of on-site equipment and the characteristics of traffic flow.

3. Time synchronization service comparison

If understood by a technical understanding, industrial ring network switches and wide-temperature industrial switches equipped with SNTP are simplified versions of the NTP protocol, with an accuracy of 1-10ms, suitable for non-critical business time synchronization. NTP Server/Client adopt a hierarchical architecture and achieve 0.5-10ms accuracy through software timestamps, working as the mainstream time synchronization solution for general industrial monitor. Power industrial switches equipped with NTP Authentication are based on key-based authentication to prevent malicious time tampering and man-in-the-middle attacks.

4. FAQ

Q1: What are the positioning differences among Moxa industrial switch, 3onedata industrial switch and Rayin industrial switch?

A: Moxa industrial switch targets global export projects with complete international certifications. 3onedata industrial switch balance cost and standard performance. Rayin industrial switch provides flexible custom PTP functions for special power and rail projects, also with good cost.

Q2: Do Moxa industrial switch, 3onedata industrial switch and Rayin industrial switch support PoE output?

A: All three series have PoE models.

Q3: Can Moxa industrial switch, 3onedata industrial switch and Rayin industrial switch work in one same PTP network?

A: Yes. All three comply with IEEE 1588v2 standard, there is no compatibility barriers. 

Q4: Do all three industrial switches support wide-temperature and dual power supply?

A: Moxa, 3onedata and Rayin industrial switch all adopt wide-temperature design and redundant power input.

5. Summary

Moxa,with more than 30 years of extensive industrial communication, it is well-known in the global industry. The product line covers the whole category equipment including industrial switches, serial port servers, industrial wireless, RTUs, etc.,all the product have passed the IEC 62443 network security certification. They have mature technologies such as TSN, 5G, WiFi6, and redundant ring networks, and are suitable for strict scenarios such as intelligent manufacturing, rail transit, and power. Their main features are high reliability and high security. 

The 3onedata, mainly engaged in industrial switches, embedded modules, industrial wireless and gateways and their research center is focused on the TSN and PTP precise clock synchronization  technology. Their business covers more than 30 countries in the world, focusing on intelligent energy, rail transit and automatic manufacturing, and their core advantage is a complete plan for mature and reliable domestic industrial interconnection.

Rayin Technology， with years of experience in the industrial network field including industrial switches, industrial control computers, industrial PON, and industrial WiFi. They focus on creating stable and secure  industrial networking solutions and can customize equipment according to the on-site conditions and undertake projects for upgrading old networks, helping customers build an independently controllable industrial network.

When choosing PTP industrial switches, people should not only focus on parameter comparisons. They should select basing on the project scenario and actual requirements. If you prefer brand reputation and market recognition, and you are suggested to choose Moxa industrial switch and 3onedata industrial switch. Both of these companies have complete product lines of rail-mounted clock synchronization switches, and can be compatible with the vast majority of industrial application scenarios.

But if it is for a complex project in power or rail traffic, and the project needs to be tailored to the synchronization mode, port configuration, equipment function, or the need for special ptp industry network, you are suggested to choose Rayin Technology’ industrial switch . Because Rayin Technology can be used for fully optimization of kinds of industrial switches such as the Ring network PTP, wide-temperature PTP, etc.
