Differences Between Telephone Optical Terminal and PDH Optical Terminal
Introduction to Telephone Optical Terminal: A Telephone Optical Terminal is a device that converts traditional telephone signals into optical signals and transmits them over optical fiber. Telephone Optical Terminal is mainly used to complete the connection between telephones or between telephones and program-controlled switches through the transmission network. Telephone Optical Terminal is widely applied in: In the surveillance fields of highways, banks, electric power, telecommunications, etc., remote transmission of video signals is required. The main solution is to use an Optical Terminal to convert video signals into digital signals for transmission over optical fiber.
Features of Telephone Optical Terminal: Provides multiple telephone interfaces, Ethernet ports, and RS232 interfaces. Compact size, easy operation, and convenient maintenance.
Function of PDH Optical Terminal: PDH Optical Terminal is suitable for small-capacity switch networking, subscriber loop networks, mobile communication (base stations), private networks, DDN networks, etc.
Main features of PDH Optical Terminal: Adopts ultra-large-scale integrated chips, featuring low power consumption and high reliability. Provides E1 remote loopback test function for convenient maintenance.
