User selectable rates

The FOMi-40 is a high speed sync fiber optic modem with remote configuration and monitoring. It supports user-selectable rates from 56 kbps to 2.048 Mbps. The FOMi-40 supports the common fiber optic wavelengths and connector types, operating over different types of fiber optic links.

An inband management channel allows the user to monitor, control and configure the remote unit using the same fiber links as for data transmission, with no interference between them.

Synchronization of local and remote units

In tail-end applications, the local FOMi-40 automatically detects the external clock rate and is locked accordingly. It also updates the remote unit’s clock rate via the management channel. This enables synchronization of local and remote units to the network clock.

The FOMi-40 is available as a standalone unit or as a card version for the LRS-24 19-inch rack with central SNMP management. A double modem card is available for the LRS-24, which supports up to 24 modems in a 4U/6U-high chassis.
