Description

The FEM is the industrys most advanced and cost effective fiber-optic E1 modem. Installed in pairs, it extends a E1 link over a distance of up to 91 miles (!) or, if short of fibers up to 25 miles over a single-fiber-strand. A comprehensive set of diagnostics allows local and remote loop-back, Local and Remote signal indication, LOS, FEF and more.

The main advantage of the FEM over virtually any other product available is the Fast Ethernet connectivity that it provides over the same link, allowing the user to connect its IP traffic (at full bandwidth!) over the same infrastructure at no additional cost at all. The FEM utilizes FibroLANs unique technology that multiplexes the time sensitive E1 traffic together with standard IP traffic, providing a total usable bandwidth of 100Mbps. The device is equipped with 4 10/100TX ports that can operate in 2 user selectable modes: aggregating the IP traffic incoming into each of these ports onto the fiber (together with the E1) or as a local switch with a fiber uplink (ideal for SMEs). The FEM is available with a variety of multi-mode and single mode fiber interfaces as well as single-fiber-strand (full bi-directional traffic) models. The FEM is standard half-rack size for economical installation in both rack-mount and desktop modes. It is equipped with a reliable internal switching power supply for extended MTBF. The optional DC power supply facilitates deployment in Telco environments. When ordered with the ETR option, it may be operated in harsh environments.
