Product Description
The iMux is a powerful fiber optic modular multiplexer capable of providing up to 16 channels of T1, RS232, 2/4
wire data and analog phone FXO/FXS services, plus four built-in 10/100M Ethernet ports, over a single fiber.
These services are supplied by the modules, up to four, that each offer four lines of communication and may be
installed in any combination. Spares or add-on modules may be ordered separately and are field installable. The
optical modules are available in both dual fiber and single bi-directional fiber (WDM), and up to 2 optical modules
may be installed, providing 1+1 hot-swappable optical protection and making the best use of fiber availability.
The iMux may be managed through SNMP, web Interface, craft port or LCD/menu keys on the front panel. It also
has an external alarm port for alarm input monitoring, as well as 4 programmable alarm contacts. The system
provides local/remote loopback functions that are ideal for network testing and maintenance. The iMux takes up
1RU and comes complete with EIA19” and 23” rack ears, or it may be used on a desktop or shelf.
