Wavelength-Selected D2525P

Isolated DFB Laser Module with PMF

Applications

■ Telecommunications

— SONET/SDH OC-48/STM-16, OC-192/STM-64

— Extended and ultralong reach

— Undersea systems

— Dense WDM systems

■ Digital video

Description

The D2525P family of DFB laser modules is

designed to be used with a lithium niobate external

modulator (see Table 4).The laser module features a

polarization-maintaining ﬁber (PMF) pigtail, enabling

it to be directly connected to a modulator without the

need of a polarization controller. The PMF maintains

the polarization of the output light to a consistent ori-

entation.This allows the D2525P to be used as a CW

light source for systems requiring extremely low chirp

such as undersea or 10 Gbits/s systems.The module

contains a multiquantum-well (MQW), distributed-

feedback (DFB) laser. This device nominally has an

output power of 10 mW. The wavelength of the laser

can be temperature-tuned for more precise wave-

length selection by adjusting the temperature of the

internal thermoelectric cooler.

The 1.5 µm D2525P Laser Module is available in a 14-pin, her-

metic, butterﬂy package.
