Fibre TX/RX Unit
Introduction
The Trusted TM Fibre TX/RX Unit T8314 is designed to extend the Trusted TM Expander Bus over
distances of up to 10km. This enables a Trusted
TM
Expander Chassis to be located remotely from the
Trusted TM system.
Note: It is recommended that if a remote Expander Chassis is to be located more than 2km from the
Controller Chassis, the route of the cable is surveyed.
The Expander Bus is extended by means of a communications link using a single mode fibre-optic
cable. The Trusted
TM Fibre TX/RX Unit converts the differential signals of the copper-based Expander
Bus to a fibre-optic signal for transmission via the single mode cable. Three totally independent pairs
of Trusted
TM Fibre TX/RX Units provide a non-interfering ‘Grey Channel’ approach to safety.
Features
• Dual 24V dc diode ORed power supply.
• Easy installation (Din rail mounting).
• Communications over a distance of 10km.
• Independent units therefore easily maintained.
• SC type connectors to two fibres (Tx & Rx).
• Low power consumption.
