Description
The E2560-type EML (without integral driver IC) is
designed for 10 Gb/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 TriQuint's existing E2500-
series of devices. These devices can replace external
modulators that are often bulkier, more expensive, and
require more drive electronics than the EML. They
incorporate a small-profile GPO
TM connector to handle
the RF signal. The package also contains a thermo-
electric cooler, thermistor, rear-facet monitor photo-
diode, and an optical isolator.
The E2560-type is available for transmission distances
of up to 20 km or 40 km.
The nominal input impedance of the E2560 version is
50
. The package is qualified to the Telcordia
Technologies
TM TA-TSY-000468 standard.
The short-haul (2 km--20 km) version of the
E2560-type (E2566) is offered as a single-channel
device operating within a wavelength range of
1530 nm--1563 nm. For 40 km, E2560 is available in a
range of ITU-T wavelengths for use in DWDM systems
operating at 10 Gb/s per channel.
The devices exhibit excellent wavelength stability, sup-
porting operation at 100 GHz channel spacing over
20 years (assuming an end-of-life aging condition of
<
100 pm). Typically, no external wavelength stabiliza-
tion is required in systems of this type, using the
TriQuint E2560 EMLs. The package also offers excel-
lent 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.
