Description
Overview
GAOTek 30-Channel Fiber Optic Voice Multiplexer, 74.56 mi Range are 30 channels voice fiber multiplexers that provide a method of multiplexing up to 30 analog (POTS) channels over single pairs of multimode or single-mode fibers. These voice fiber multiplexers solve the problem of limited available fiber, reduce equipment space, and lower overall equipment costs. In addition to voice (POTS), the voice multiplexers also come with 4 x 10 or 100 Base-T Ethernet ports, 4 x RS232 ports, and 4 x E1 ports. All ports operate simultaneously over the fiber optic cable and can be used with leased lines to build private networks and private telephone networks. Their merits include complete warning functions, high integration, low consumption, stable performance, and convenient usage. The 30 voice (FXS or FXO) phones over fiber multiplexers can be managed by SNMP management; users can monitor various devices’ operation status easily.
