What is the function of AGC optical communication products
In 1925, developed an automatic volume control (AVC) system and later received U.S. Patent 1,866,687 for the invention. The patented system used a relay in the (RF) current path; detector plate current actuated the relay to regulate receiver gain. In a 1928 paper, Wheeler introduced a fully electronic version that eliminated the mechanical relay. In this design, the carrier signal was rectified, audio-frequency components were filtered out, and the resulting DC contro.

PoE Switch Networking Tutorial
Power over Ethernet (PoE) managed switches simplify this process by providing both power and data through a single Ethernet cable. This article guides you step-by-step on creating a smart home with PoE managed switches, highlighting essential components, setup details . A PoE switch is a network switch that utilizes PoE technology to transmit power and data over the same Ethernet cable to powered devices such as IP cameras, wireless access points, and VoIP phones, simplifying installation and reducing maintenance costs. It has been standardised by the IEEE but there are also vendor implementations that are non standard. It utilizes efficient low-voltage 43 to 57 VDC over twisted-pair network cabling, such as Category 6A, Category 6, and Category 5e. This eliminates the need for separate power adapters, reducing cable clutter and. We can use TL-POE150S and TL-POE10R to expand the network for the place where power line can not reach or there is no outlet.
