Description
The E2560-series EML (without integral driver IC)
and E2580-series EML (with integral driver IC) are
designed for 10 Gbits/s DWDM or TDM transmission
applications. They integrate a CW laser with an elec-
troabsorptive modulator in the same semiconductor
chip and are an extension of Lucent Technologies
Microelectronics Group’s existing E2500-series of
devices. These devices can replace external modula-
tors that are often bulkier, more expensive, and
require more drive electronics than the EML. Both
series use a small-profile Gilbert GPO connector to
handle the RF signal. The package also contains a
thermoelectric cooler, thermistor, rear-facet monitor
photodiode, and an optical isolator.
The 2560-series is available for transmission dis-
tances of up to 20 km, 40 km, and 60 km. The 2580-
series operates over distances of 40 km and 80 km.

Description
(continued)
The nominal input impedance of the E2560 version is 50
Ω
. The package is qualified to the
Telcordia
Technologies
* TA-TSY-000468 standard.
The short-haul (2 km—20 km) version of the 2560-series (E2566) is offered as a single-channel device operating
within a wavelength range of 1530 nm—1563 nm. For 40 km and longer applications, 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 devices exhibit excellent wavelength stability, supporting operation at 100 GHz channel spacing over 20 years
(assuming an end-of-life aging condition of <
±
100 pm). Typically, no external wavelength stabilization 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
