The FOL-1601 is a fiber optic receiver that restores an L-band satellite signal that has been received from a single-mode fiber. The fiber transmission is totally protocol transparent and both transmitter and receiver maintain high signal fidelity over the whole transmission. The FOL-1601 accepts a wide range optical input (1270 nm - 1610 nm) and provides manual gain control (MGC) to compensate for any optical loss.
