Acapella Optical Modem IC

* Full duplex serial transmission through a single fiber-optic

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

* 4 clock domains for independent transmission of 4 * E1 or

* 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 up to 4 maintenance channel at 16kbps

* Bit Error Rate (BER) of < 10

* Typical latency of 0.75ms.

The ACS406CS 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

ACS406CS provides either 1 x 64kbps or 4 x 16kbps auxilliary

maintenance channels.

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.
