What is the difference between fiber optic transceiver tx and rx?
The fiber optic transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a photoelectric converter (Fiber Converter) in many places. Products are generally used in the actual ne...Read more -
What is the difference between a managed switch and a unmanaged switch?
At present, switches on the market can be divided into managed switches and unmanaged switches. How much do you know about these two types of switches? What is the difference between the two? How should I choose? What is a network management switch? The network management switch mainly performs f...Read more -
What are the obvious advantages of managed switches over unmanaged switches?
1. Unmanaged switches First of all, let’s talk about unmanaged switches. Unmanaged switches are also called fool switches. Simply put, they don’t directly process data, just plug in the Internet cable. The unmanaged switch belongs to the data link layer device. It can identify the MAC...Read more -
How many devices can a PoE industrial switch supply power?

How to ensure stable connection of PoE switch?
With the continuous development of PoE technology, PoE switches are currently in a very mature stage,however, due to the current monitoring market under the pressure of cost, the quality of the selected PoE switches or cables is too low, or the scheme design itself is unreasonable, which will res...Read more -
Security advantages of PoE switches
Security advantages of PoE switches ① The PoE switch can solve the problems of short circuit, excessive overload, voltage change, etc., and can provide good power supply protection. ②The standard PoE switch will provide a low-voltage detection terminal device to support PoE device before power su...Read more -
Single-mode/multi-mode optical module and its usage
Where are the application of single/multimode fiber and single/multimode optical module? (1) Single-mode fiber can make the fiber be directly transmitted to the center, and is generally used for long-distance data transmission; in multi-mode fiber, optical signals propagate through multiple chann...Read more -
The difference between single/multimode fiber for industrial-grade fiber media converter
Fiber media converter can be divided into single-mode fiber and multi-mode fiber according to the transmission mode in the fiber. The most fundamental difference between single-mode and multi-mode is the transmission distance. Industrial grade fiber media converter: the difference between singl...Read more -
Solutions to common faults of PDH optical transceiver
Permanent failure: For permanent faults, a loop can be used at one end, and the other end can be displayed from the switch or judged section by section and layer by layer with a transmission analyzer. 1. Transmission alarms appear in pairs. For example, if RJA (remote alarm) occurs on the A si...Read more
