1. Description

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:

Fibre TX/RX Unit Block Diagram

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 ‘F’ filter. Signals originating from the Trusted

Expander

Processor Module in the remote Expander Chassis are processed in the same manner.
