Isolated Laser Module (EM-ILM)
E2500-Type 2.5 Gbits/s Electroabsorption Modulated
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 Gbits/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 Agere’s E2500-
Type EM-ILM.
The E2500-Type EM-ILM is qualified for DWDM appli-
cations to Bellcore TA-TSY-000468.
