DR-PL-10-MO

Pulse Medium Output Voltage Driver Module

Photline Driver

The Photline DR-PL-10-MO RF drivers are amplifiers module designed todrive LiNbO3 optical modulators so as to generate undistorted optical pulses.
Electrical pulsed signals differ from classical telecom signals by longperiods with no signal, when telecom signals are usually well balanced in 1and 0. They also differ from analog signal by a wider frequency content. In
order to generate clean optical pulses with sharp edges, sustained high andlow levels and no overshoot, pulsed signals do require specific amplifiers.

FEATURES• Specific design for pulse signals• Accommodate a variety of pulse formats• High pulse fidelity
APPLICATIONS• Pulse generation• Pulse picking

The Photline DR-PL-10-MO driver is optimized for low and high Pulse
Repetition Frequency (PRF) signals from 10 Hz to GHz. The bandwidth up
to 10 GHz accommodates 100 ps narrow pulse width with short rise and falltime (down to 25 ps) and can withstand longer pulses up to 100 ns.
The Photline DR-PL-10-MO drivers come in compact connectorized modules
that match directly with Photline modulators, they use a single voltage power
supply for ease and safety of use and feature an output voltage control formaximum flexibility. An optional heat sink is proposed as an accessory.
