RAD FOM-40/115/SC13L/T1

FOM-40 Fiber Optic Modem • FOM-40 operates with several grades and sizes of fiber optic cable. Different optical interfaces are available: � 850 nm VSCEL for use with multimode fibers � 1310 nm laser for use with single mode fibers � 1550 nm laser for use with single mode fibers for an extended range of up to 100 km (62 miles). • Three clocking modes are available for maximum flexibility: internal clock, receive loopback clock and external DTE clock. FEATURES DESCRIPTION • Diagnostics include local analog and digital loopbacks, and remote • FOM-40 is a long-range fiber optic • Synchronous fiber optic digital loopback. The loopback modem that transmits data over modem with a wide range commands are controlled either by up to 100 km (62 miles), and is a of selectable data rates: a manual switch, or via the DTE secure data link between from 56 to 2048 kbps interface signals. A front panel computers, routers, multiplexers, switch generates an internal • Supports various types of and other data communication pseudo-random test pattern devices. It operates at twelve single or multimode fiber (511 bits) according to the ITU selectable synchronous data rates • Extended transmission range V.52 standard, for testing from 56 kbps to 2048 kbps. end-to-end connectivity.
