Alcatel 1948 PLI
High power 1480 nm
Pump Laser module with Isolator
Description
The Alcatel 1948 PLI module contains a
SLMQW 1480 nm high power laser coupled
to the pigtail with an optical isolator.
It incorporates a thermo-electric cooler,
precision NTC thermistor, and a monitor
photodiode. The Alcatel 1948 PLI can be
pigtailed with a standard Single Mode Fiber
(SMF) or a Polarization Maintaining Fiber
(PMF).
The Alcatel 1948 PLI is dedicated to 1480 nm
pumped Erbium-Doped Fiber Amplifiers (EDFA).
