| Functioning as stand alone modules or in conjunction with fiber optic modems, the new dual channel isolators operate with encryption devices in a datacomm/telecomm link. They are data agile (any frequency) from 250 bps to 10 Mbps and permit clocking and resynchronizing of encryption equipment from a remote location. The isolators pass data or clock signals with Bit Error Rates (BER) of 10 to the minus 9th across the entire bandwidth of 250 bps to 10 Mbps. Link budget is not less than 19 dB on 100/140 fiber optic cable.
FEATURES
Full data agility adds flexibility and reduces hardware costs. Any signal from 250 bps to 10 Mbps may be passed to accommodate existing systems as well as signal variations. Note: Unbalanced signals up to 100 Kbps. Balanced signals up to 10 Mbps.
The dual channel isolators transmit data in one direction only, thus preventing data from returning in the opposite direction which helps assure data security.
Wide operations flexibility is also offered by the dual channel isolators since many different electrical interfaces are available (see Selection Guide) to accommodate existing telemetry systems through jumper selection.
Annuciator lights are used as status indicators on the dual channel isolators. Their function is as follows:
Transmitter board (F2900):
PWR - Power on indication for normal operation
ALM - Out of sync indication
TCH1 - Transmit channel one
TCH2 - Transmit channel two
Receiver board (F2900):
PWR - Power on indication for normal operation
ALM - Out of sync indication
RCH1 - Receive channel one
RCH2 - Receive channel two
