AIM-USA (St. Omaha, NE) has introduced the new FOMIS and FOL429 fiber optic bus extension systems. The FOMIS (Fiber Optic MILbus Stub Extension) product provides a highly modular and scalable system capable of extending MIL-STD-1553 bus stubs up to 500 meters. FOMIS systems can also be combined with the FOL429 modules to provide up to 500 meter extensions of ARINC429 data links. FOMIS and FOL429 are designed to support test applications, such as vehicle launch sites, anechoic chambers, and engine testing, that require an extended distance between the Unit Under Test (UUT) and the remote test equipment.

The FOMIS system consists of a FOMIS-F (or FOL429-F) Front-End module and FOMIS-L (or FOL429-L) remote/lab module. The Front-End and Lab modules are interconnected via a COTS fiber optic link (62.5/125uM multimode fiber).

EMC resistant housing allows operation in electromagnetic fields up to 200V/m. Options supporting extended temperature and standalone (battery powered) operation are available. The FOMIS-L is housed in a 19" rack mountable chassis. System operation is completely plug and play, and no software or configuration is required.
