What do you know about SFP module?
What is SFP module? The SFP module is an interface device that converts gigabit electrical signals into optical signals. It is an industry-standard small and pluggable gigabit optical transceiver module that can be plugged into the SFP of network equipment such as switches, routers, and media con...Read more -
The safe transmission distance and network cable selection of POE power supply
The safe transmission distance of POE power supply is 100 meters, and it is recommended to use Cat 5e copper network cable. It is possible to transmit DC power with a standard Ethernet cable for a long distance, so why is the transmission distance limited to 100 meters? Next, we will follow JHA T...Read more -
How to choose an fiber video converter in a security monitoring system?
Multi-channel digital video optical transceivers can have multiple functions, and each type of function has corresponding technical index requirements, such as video index, audio index, asynchronous data index, Ethernet index, telephone index and so on. Specific technical indicators can require t...Read more -
How to choose fiber video converter?
Optical transceivers are also optical signal transmission equipment. Foreign optical transceivers have mature technology but are expensive. Although domestic optical transceivers are not so mature in technology, they are not expensive enough to deal with internal ones. Then what is the select...Read more -
We should choose 100M or 1000M ethernet switch?
In order to be able to load the increasingly complex video surveillance system network, the switch needs to access more cameras, and the larger the data volume of the switch. The switch must have a very stable ability to convert data to transmit large amounts and continuously Video data. So, shou...Read more -
Why must the industrial field use industrial ring network switches?
1. Harsh industrial site environment Since Ethernet was designed at the beginning, it was not based on industrial network applications. When it is applied to industrial sites, facing harsh working conditions, serious inter-line interference, etc., these will inevitably cause its reliability to de...Read more -
The difference between industrial and commercial switches
We all know that there are commercial grade and industrial grade switches. Commercial grade switches are generally used in homes, small businesses and other places. Industrial-grade switches are often used in industrial environments. So, why can’t commercial grade switches be used in indust...Read more -
Analysis of Gigabit Ethernet Switch Failure and Packet Loss
There are many things worth learning about Ethernet switches. Here we mainly introduce how to avoid packet loss in the energy data control of Gigabit Ethernet switches. Flow control cannot improve the data throughput of the entire switch, but it avoids packet loss in the switch. Gigabit Ethernet...Read more -
Why do industrial switches need CE certification?
Industrial switches are used more and more widely, whether it is our domestic market or foreign markets, there are a large number of them, and they have become international trade. When exporting to foreign industrial switches, switches are necessary when entering foreign countries. To have the C...Read more -
The concept and function of optical modem, router, switch, wifi
Today, the Internet has entered thousands of households, and the Internet has become an indispensable thing in our lives. Generally, the most common network devices at home are: optical modems, routers, switches, wifi, but many users cannot easily distinguish them. When you encounter a network fa...Read more -
How to distinguish the quality of fiber optic transceivers
Speaking of fiber optic transceivers, we have to say its transmission stability and transmission distance. However, poor quality optical fiber transceivers are subject to various tests, so how do we distinguish poor quality optical fiber transceivers? First look at the production logo. A good fib...Read more -
Common troubleshooting methods for HDMI fiber video converter
Failure and solution: No video signal: 1 Check whether the power supply of each device is normal. 2 Check whether the video indicator of the corresponding channel at the receiving end is on: A: If the indicator light is on (the light on proves that the channel has video signal output at this tim...Read more
