1 Introduction
The Outdoor Enclosure type MINI (ODE-MINI), is a cost-effective weatherproof enclosure for ViaLiteHD
systems and associated hardware. It is intended to service the requirements of most GPS timing and satellite
communication systems though can be configured to suit a wide range of other applications.
The ODE-MINI system is comprised of the following key parts:

IP-65 rated external enclosure fitted with:

Dual power supplies (redundancy or power sharing)

Capacity for up to two ViaLiteHD OEM modules with front panel connections

Termination of input power cable (inside the supplied quick release latching connector)

Patch box for termination of optical cable (various quad fibre cable lengths available)

Connectorised RF inputs / outputs.
It has a wide range of optional accessories including:

Lightning suppressor(s)

Optical cable

Wall or pole mount fixings.
ViaLiteHD RF Fibre Optic Links (FOLs) are a family of fibre optically coupled link systems designed for the
transmission of RF analogue signals over long distances for the communications market.
ViaLite is a product brand manufactured by Pulse Power and Measurement Ltd (PPM).
ViaLite Communications is a division of Pulse Power and Measurement Ltd (PPM).
1.1 Typical deployment
A typical system operates as follows.
The ODE-MINI would house a set of FOL TX modules, in a remote outdoor location connected to antenna
equipment. Antenna electrical signals are input to the transmitter modules, which contain RF signal
conditioning and laser control circuitry. The modules modulate the intensity of a beam of light with the RF
signal for optical transport over a fibre optic cable.
The light travels through the optical fibres to corresponding receiver modules. The distance between
transmitter and receiver can range from 1 m to 100 km; distance in excess of 100 km can be achieved with
more complex optical transport systems, depending on the system specified.
The receiver module converts the modulated light back into an electrical signal, which is available at its
output.
1.2 ViaLiteHD compatibility
The RF and optical interfaces are compatible with all ViaLiteHD Blue modules.

ViaLite Communications or your local ViaLite agent for more details.
1.3 Care of fibre optic connectors
When the fibre optic cables are not connected, it is essential that the cable and equipment connectors are
protected by the dust caps provided with the system. Failure to do so may result in damage to the fibre ends,
which are critical to the system performance. Please refer to section 1.4 for fibre optic cable handling details.
