1 FOL-1601 L-Band Fiber Receiver
1.1 Introduction
The FOL-1601 is a fiber optic receiver that allows an L-band satellite signal to be generated from a single
mode fiber. The fiber transmission is totally protocol transparent and the FLO-1601 / FOL-1601 maintains
high signal fidelity over the whole transmission.
The FOL-1601 accepts a wide range optical input (1270nm-1610nm) and incorporates manual gain control
(MGC). The RF link gain, when using an FLO-1601 coupled with a FOL-1601, can be adjusted to unity using
the MGC in the FOL-1601, thus preserving the input RF level regardless of the optical power or distance
between the transmitter and the receiver.
Housed in the DENSITÉ frame, and easily controllable via the iControl software or the frame controller menu,
the FOL-1601 occupies only one slot, which makes it an ideal cost-efficient solution for connecting satellite
dishes to a studio or any other application involving seamless terrestrial transmission of L-band satellite
signals.
