* Full duplex serial transmission through a single fiber-optic

* E2 data-rates of 8.448Mbps or 4*E1 at 2.048Mbps.

* Link lengths up to 25km (50km at reduced bandwidth).

* Single wavelength of light to transmit and receive data.

* Low power, zero cross talk between Rx and Tx channels.

* Incorporates maintenance channel at 64kbps.

* Bit Error Rate (BER) of < 10

* Typical latency of 0.75ms.

* Ping Pong system supporting bi-directional Laser

The ACS405CS is a complete controller, driver and receiver chip-set,

supporting full-duplex synchronous transmission up to 8.448/6.312Mbps

over a single-optical fiber. The designer can share the available

bandwidth over 1 to 8 main channels by selecting the appropriate

combination on the DR input pins. In addition to the main channels, the

ACS405CS provides up to two auxilliary maintenance channel of

64kbps.

The internal machine cycle provides for link lengths up to 25/50km. On

the electrical side HDB3/AMI/NRZ/B8ZS interfaces are selectable.

Communicating modems automatically maintain synchronisation with

each other, such that the receive phase of one modem is lined-up with

the transmit phase of the other, compensating for the propagation delay

presented by the link. Link lengths from zero to maximum distance are

catered for automatically.
