Е1 Оптоволоконный модем / мультиплексор PDH

Overview:The optical MODEM series can implement the conversion between E1, V.35, V.24, RS232, and Ethernet ports and optical fiber for transmission. It can be extensively used in various accessing conditions for operators and industrial clients, such as DDN, SDH and special transmission network which need to be extended by optical fiber. Product Features: The equipment can provide local, remote loop-back functions and pseudo-random code testing function, facilitating the launch of network and the usage of loop-back function will not result in the meltdown of network;E1 port can support 120 Ω resistance and 75 Ω resistance simultaneously;V.35 user port can support N*64K (N=1 32) adjustable velocity, and can support internal, external and slave clock modes, so as to be adapted to various application conditions; and it can work under DTE or DCE modes.V.24 port can support rate of 64K or 128K (optional), and can conduct transmission at any specified time-slot in E1 port; and it can work under DTE or DCE modes.RS232 port can support the adaptive rate lower than 115.2K.Ethernet port can support N*64K (N=1 32) adjustable velocity, and can support four channels of switched Ethernet port and can be channel-isolated; Ethernet mode can support 10M/100M semi-duplex and 10/100M full-duplex modes and adaptive mode (optional), and support VLAN protocol;It can be connected to the user port of converters produced by the company to implement internet construction via optical extension.
