4 E1 + 100M Ethernet PDH-Multiplexer / Optical Multi

Overview:The optical multiplexer series can implement the conversion between ports of multiple E1, Ethernet, and serial port and optical fiber for transmission. It is based on proprietary intellectual property rights, with high integration level, and can implement lossless switch protection of two optical ports; it can be extensively used in various accessing conditions for operators and industrial clients, such as DDN, SDH and special transmission network which needs to be extended by optical fiber. Product Features: The optical port can support 1+1 protection and lossless switch;It can support 16 channels of E1 channels, and the E1 port can support the resistance of 120 Ω/75 Ω; and each E1 has independent loop-back function for the convenient circuit detection of user;The bandwidth of Ethernet can support 100M, and provide two Ethernet ports with switch function, and the Ethernet port can support the following functions: VLAN isolation, adaptive for crossover cable and straight cable, and 10M/100M semi-duplex and 10/100M full-duplex modes and adaptive mode (optional);It can support one channel of RS232 port and one external warning port (or two channels of RS232 ports), which can be selected according to the requirements of user, and RS232 has adaptive rate for lower than 115.2K;It can support a channel of service telephone.CONSOL network control port can be provided as per requirement of user.The equipment can support double powers of AC220V and DC48V.Product Specification:OT-4E1Single/double optical port-4 channels of E1 ports, can be provided with serial port, service telephone, external warning port etc.OT-8E1Single/double optical port-8 channels of E1 ports, can be provided with serial port, service telephone, external warning port etc.OT-16E1Single/double optical port-16 channels of E1 ports, can be provided with serial port, service telephone, external warning port etc.OT-4E1*ETHSingle/double optical port-4 channels of E1 ports and 100M Ethernet port, can be provided with serial port, service telephone, external warning port etc.OT-8E1*ETHSingle/double optical port-8 channels of E1 ports and 100M Ethernet port, can be provided with serial port, service telephone, external warning port etc.OT-16E1*ETHSingle/double optical port-16 channels of E1 ports and 100M Ethernet port, can be provided with serial port, service telephone, external warning port etc.
