Wavelength-Selectable High-Power

D2547P-Type CW DFB Laser Module

Applications

Telecommunications:

— Dense WDM

— SONET/SDH OC-192/ STM-64

— Extended and ultra-long reach

— Undersea systems

Digital video

Description

The D2547P-Type DFB laser module is designed for

use with an external lithium niobate modulator and

also in applications where high power (20 mW) is

required.

The laser comes packaged in an industry-standard

14-pin butterfly module with a polarization-maintain-

ing fiber pigtail.

Temperature-stabilized with a thermoelectric cooler

(TEC) and thermistor, the package is available in C

and L band ITU-T grid wavelengths on a 100 GHz

spacing plan.

D2547P does not contain a wavelength locker, which

is not needed for high-reliability operation in

100GHz-spaced applications. For a 20 mW CW laser

butterfly version with integrated wavelength locker

and available on a 50 GHz grid, refer to the compan-

ion product data sheet for D3587P.

Featuring wavelength selection to the DWDM ITU-T grid, the

D2547P Laser Modules are ideally suited for use with external

lithium niobate modulators, and in high-power (20 mW) appli-

cations.

Features

High-performance, multiquantum-well (MQW),

distributed-feedback (DFB) laser

D2547P-Type is offered on 100 GHz ITU grid

wavelengths ranging from 1528.77 nm—

1610.06 nm

Polarization-maintaining fiber pigtail

For use with lithium niobate modulators

High optical power (20 mW, CW)
