The interconnection networks, based on fiber optic components, are designed to connect the nodes of tactical networks

with the help of optical fiber cables. The Expanded Beam technology used preserves all advantages of signal transmissions

through optical lines in harsh environmental field conditions.

For example, the tactical fiber optic cables with Expanded Beam connectors allow arranging the connection between

headquarters and subaltern points in field conditions in a very short time. The flexible 2 – 6 fiber 6mm outer diameter optical

cables have a high crush and strain relief resistance and a rugged field repairable connector design. The wide range o fcable drums

has been developed to facilitate storage and handling with cable coils. The drums are designed to store up to 500 m tactical cable

and the low weight of the cable coils allows easy network reconfiguration in field conditions.

The optical interface of the active networking device should be based on the same Expanded Beam technology, preferably on the

same standards used for installation of the passive infrastructure of the tactical fiber optic network. The LMSW-10 ruggedized field

switch has been developed according to the above mentioned requirements. The switch combines all advantages: excellent optical

network performance and rugged construction designed for operation in harsh environmental conditions. The LMSW-10-282

includes a 10 port switch (2 fiber optic, 8 UTP LAN ports) and a VoIP gateway with 2 FXS ports. The LAN1-4ports offer PoE

(Power over Ethernet) capability.
