E2500-Type 2.5 Gb/s Electroabsorption Modulated Isolated Laser Module (EM-ILM) for Ultralong-Reach Applications

TriQuint Semiconductor 

E2500-Type 2.5 Gb/s Electroabsorption Modulated

Isolated Laser Module (EM-ILM)

Data Sheet, Rev. 1

February 2003

Description (continued)

The package also contains a thermoelectric cooler,

thermistor, back-facet monitor, and an optical isolator.

This device exhibits excellent wavelength stability,

supporting operation at 100 Gb/s channel spacing,

assuming an end-of-life condition of < ±100 pm over 20

years for wavelength aging, with very low FIT rates.

Wavelength stabilization schemes are not required in

DWDM systems of this type, using TriQuint’s E2500-

Type EM-ILM.

The E2500-Type EM-ILM is qualified for DWDM appli-

cations to Telcordia ™ TA-TSY-000468.
