FiberPlex FOM-1090 - Manual (Page 4)

Introduction
The FOM‐1090 and FOM‐1091 fiber optic isolator\modem cards provides for full synchronous, asynchronous,
or isochronous interfacing to serial data communications equipment. The unit is transparent to all data
formats and protocol, and supports timing from the DCE and DTE as well as uncommon clocking styles such as
gapped clock or gated clocks that stop in different states to indicate status. The status and direction of all
supported signals is shown on front panel indicators in addition to power supply and optical link status for
each card.
