Overview of SFP optical modules
January 8, 2020
The SFP optical module is a hot plug small package module encapsulated by SFP. The current maximum rate is 10.3 G and the interface is LC. SFP optical modules are mainly composed of lasers. SFP classification can be divided into rate classification, wavelength classification, and pattern classificat...
The difference between SFP, SFP +, XFP-optical modules
January 8, 2020
Many people are not clear about the difference between SFP + and SFP and XFP, so it sometimes brings unnecessary trouble(security against weak circuits). The 10G module experienced the development of 300Pin, XENPAK, X2, and XFP, and eventually achieved the transmission of 10G signals in the same ...
Do optical transceivers have to be used in pairs?
December 28, 2019
Do optical transceivers have to be used in pairs? Does the optical transceiver receive one and send the other? Or is it just two optical transceivers that make up a pair? If the optical transceiver must be used in pairs, is it the same brand and model? Or can any brand be used in combination? Answer...

Advantages of PoE+Switches
December 10, 2019
(1) Higher power: PoE + switches can provide up to 30W power per port, while PoE switches can provide up to 15.4W power per port. The minimum power available on the power supply equipment of the PoE switch is 12.95W per port, while the minimum power available on the PoE + switch is 25.5W per port. ...
PoE power supply process
December 2, 2019
First, let's look at the power supply principle and process of PoE. When PSE power supply devices are deployed in a network, the power supply process of PoE Ethernet is shown in the following figure. 1. Testing At first, the PSE device outputs a very small voltage at the port until it detects that ...
