Raytum Photonics core-pumped fiber amplifiers offer >20 dBm (>100 mW) output power

with a low noise figure . They are enclosed in a compact, turnkey benchtop package with FC/APC input

and output connectors. The “Pre-S” units are single mode amplifiers with minimal sensitivity to the light polarization,

while the “Pre-P” units are polarization-maintaining amplifiers that only amplify light polarized along the slow axis

of the fiber. Each unit includes built-in input and output isolators.

The pump current of the fiber amplifiers are adjustable through the instrument's front panel,

allowing the user to vary the gain and output power of the amplifier. In addition, a tap output is included

on the back panel for customer to actively monitor the amplifier performance. For added safety, the user

may connect an interlock circuit to the 2.5 mm mono jack on the rear panel.

Each EDFA uses a universal power supply allowing operation over 100 - 240 VAC, 50 - 60 Hz without

the need to select the line voltage. A region-specific power cord is included.
