VERSITRON fiber optic modems provide fully transparent point-to-point copper-to-fiber conversion. Styles available include our FOM II Series and our MicroModem Series. Multimode or single mode modems are available with standard ST optical connectors. Transmission distances vary and will depend on the type of signal being converted and the link budget between the modems.

VERSITRON FOM II modems provide conversion for either data and/or analog links. Standalone enclosures or rack mount chassis offer complete flexibility for installation options.
Minimum requirements: 2 modems (per link), enclosures and/or chassis, power adapters or supplies.

Versimux is a versatile fiber optic multiplexer system that allows data and/or analog signals to be combined into one signal in a single plug-in chassis with power supplies and a Channel Allocation Master (CAM) multiplexer card. Signals are multiplexed and transmitted together over multimode or single mode fiber cable. ST optical connectors are standard.
Minimum requirements: 2 chassis, 2 Channel Allocation Master Cards, 4 Power Supplies, 2 Port Cards.

Clock Distribution System

The VERSITRON Clock Distribution System CDS-20 is an upgrade of the CDS-10. In its standard configuration, the system generates 155 different clock frequencies and has the ability to distribute up to 84 different frequencies at one time. Utilizing external reference oscillators, the system provides frequencies with typical stability of one part in 10¹². (Stratum I).
Minimum requirements: 1 Chassis, 2 Power Supplies, 1 Reference Module, 1 Master Divider Card, 1 Line Driver Card.
