The M3-SE-TFOCA-10G module takes a standard Tactical Fiber Optical Cable Assembly II (TFOCA-II) connection and converts it to standard commercial fiber or copper Ethernet connections. The module contains two physically isolated, nondata path crossing converters, which allows for network separation of two data paths in a single box. One path converts 10 Gb Ethernet TFOCA-II to a Small Form Factor Pluggable (SFP+) connection which can be used for either a fiber or copper depending on SFP module installed. The other path converts TFOCA-II to an RJ-45 Gigabit Ethernet connection. When stacked with another M3-SE product, it uses the power pass-through feature allowing a single power cord and optional battery backup capability.
