Transport POTS, 4W DATA, RS-232, T1, & Gigabit Ethernet Over Fiber​

iMux Multiplexer System
Front Panel

iMux SPFThe iMux is a powerful fiber optic modular multiplexer capable of transmitting over fiber up to 16 channels of T1, RS232, 4 Wire Data, and POTS. Additional to the 16 channels every system includes a built-in 4 Port Gigabit Managed Ethernet switch.

Each of these services are supplied by our communication modules, each module will transport up to 4 channels of the specified service and may be installed in any combination. Spares or add-on modules may be ordered separately and are field installable.

Gigabit SFPs are used for the back-haul fiber transport of the communication services. Each iMux will take up to 2 SFPs for redundancy. The SFPs are hot swappable and automatically fail over in case of a failure in the primary fiber path.

The iMux may be managed through SNMP, web Interface, craft port or menu keys on the front panel. It also has an external alarm port for alarm 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.
