T8314 ICS TRIPLEX Trusted Fibre TX/RX Unit Brand New

Description:

The Trusted® Fibre Transmitter/Receiver (Tx/Rx) Unit T8314 is designed to extend the Trusted Expander Bus over distances of up to 10 km. This enables a Trusted Expander Chassis to be located remotely from the Trusted System.

Note: It is recommended that if a remote Expander Chassis is to be located more than 2 km 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 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 Fibre TX/RX Units provide a non-interfering ‘Grey Channel’ approach to safety.

The Trusted Fibre TX/RX Unit T8314 is designed to be DIN rail mounted in the rear area of a cabinet/bay containing the Trusted Controller Chassis T8100. A block diagram of the Unit is shown in Figure 2 below:

The Unit provides a communications connection interface between the Trusted Controller Chassis and a remote Expander Chassis.

The Positive Emitter Coupled Logic (PECL) signal from the Trusted Expander Interface Module in the Controller Chassis is connected to the Unit by a Trusted Expander Cable TC-302. The signal is fed through an isolator, then filtered and terminated before being connected to the PECL input of the Fibre-optic Transceiver. The fibre-optic signal is transmitted to a similar Unit at the remote end via a Single Mode Fibre-Optic Cable. The Fibre-optic Transceiver at the remote end of the link converts the signal back to a PECL signal before transmitting it to the Trusted Expander Processor Module via a filter/termination circuit, isolator and ‘π’ filter. Signals originating from the Trusted Expander Processor Module in the remote Expander Chassis are processed in the same manner.
