RAD FOM-40

FOM-40 Fiber Optic Modem • Three clocking modes are provided for maximum flexibility: Internal clock, Receive Loopback clock and External DTE clock. • FOM-40 utilizes a Phase Locked Loop (PLL) circuit to recover jitter-free data and clock from the 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 via the DTE interface signals.
