E2560/E2580-Type 10 Gbits/s EML Modules
January 1999

Lucent Technologies Inc.
Description (continued)
The nominal input impedance of the E2560 version is 50
. The package is qualified to the Bellcore TA-TSY-
000468 standard.
Both E2560 and E2580 are available in a range of ITU-T wavelengths for use in DWDM systems operating at 10
Gbits/s per channel. The device has excellent wavelength stability, supporting operation at 100 GHz channel spac-
ing over 20 years (assuming an end-of-life aging condition of <
±100 pm). Typically, no external wavelength stabili-
zation is required in systems of this type, using Lucent's E2500 series EMLs. The package also offers excellent
stability of wavelength vs. case temperature, with a maximum coefficient of 0.5 pm/
°C.
