FOM-20 fiber optic modem from RAD

The FOM-20 fiber optic modem provides a secure, long-range data link between computers, routers, multiplexers, and other data  communication devices. The RAD FOM-20 operates at 16 selectable synchronous or asynchronous data rates from 19.2 kbps to 256  kbps. The built-in Ethernet bridge option enables cost-effective LAN-to-LAN connectivity without the need for an external bridge. 
FOM-20 converts electrical signals from DTE equipment into optical signals using an infrared light emitting diode (LED) or  laser diode.

The following DTE interfaces are available on the FOM-20:
V.24/RS-232
V.35
X.21
RS-530
V.36 (RS-449)
Built-in Ethernet bridge
G.703 codirectional (64 kbps).

FOM-20 operates with several grades and sizes of fiber optic cable, and can be ordered with the following interfaces:

850 nm LED/VCSEL for multimode fibers
1300 nm laser for single-mode fibers
1550 nm laser for single-mode fibers.

FOM-20 provides immunity against electrical interference, such as EMI, RFI, spikes, and differential ground loops. Sparking  and lightning protection is provided and a secure link is maintained in hazardous or hostile environments. Three clocking  modes provide maximum flexibility: internal clock, receive loopback clock, and external DTE clock. A phase locked loop (PLL)  circuit recovers jitter-free data and clocking from the incoming optical signal. 

V.54 diagnostics are used for local analog and digital loopbacks, and remote digital loopback. The loopback commands are  controlled either by a manual switch, or through DTE interface signals. For testing end-to-end connectivity, BER tests generate an internal pseudo-random test pattern (511 bits) according to the ITU V.52 standard. The ERR LED flashes whenever a  bit error is detected.
