Alcatel 1948 PLI

High power 1480 nm

Pump Laser module with Isolator

De scrip tio n

• Low drive current

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).

• SMF or PMF

• 30 dB optical isolation

• InGaAsP SLMQW laser

• Internal TEC and monitor photodiode

• Hermetic 14-pin butterfly package

• Full performance in operating case

temperature from 0 to + 70 °C

The Alcatel 1948 PLI is dedicated to 1480 nm

pumped Erbium-Doped Fiber Amplifiers (EDFA).
