E2500-Type 2.5 Gbits/s Electroabsorption Modulated Isolated
Laser Module (EM-ILM) for Ultralong-Reach Applications
Applications
■
SONET/SDH extended-reach applications
■
High-capacity DWDM system applications
■

Description
The E2500 EM-ILM, the newest generation of the awardwinning 266-Type EM-ILM, features an integrated modulator
and laser chip, and provides a compact, cost-effective solution for extended-reach transmissions.
Features
■
Integrated electroabsorptive modulator
■
1.5 µm wavelength
■
Characterized for 2.5 Gbits/s operation
■
Very low dispersion penalty over 600 km
■
Low modulation voltage
■
Temperature stabilized
■
Wavelengths selectable to ITU-T standards
■
Ultrastable wavelength aging performance for
DWDM systems
The E2500-Type EM-ILM is a 1.5 µm laser with an
integrated electroabsorptive modulator packaged in
an industry-standard, 14-pin butterfly package. The
device has been designed to be used in 2.5 Gbits/s
extended-reach applications where the distances
between regenerators is in the range of 150 km—
1000 km. To boost the transmitter power high enough
to reach the receiver, the device typically is coupled
with an erbium-doped fiber amplifier (EDFA) such as
Agere Systems Inc.’s 1724 EDFA. The standard
product is specified for use up to 360 km (E2505
Series) and 600 km (E2502 Series).
The E2500 EM-ILM can replace external modulators
in many applications. The nominal input impedance
for the modulator is 50 Ω. By integrating the
modulator with the laser chip, the device offers a
compact, cost-effective solution for extended-reach
transmission applications. It can also be specified for
WDM applications where wavelength selection is
required. Agere is providing devices compatible with
the ITU-T wavelength standards.

Pin Information
The package also contains a thermoelectric cooler,
thermistor, back-facet monitor, and an optical isolator.
Table 1. Pin Assignments
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 E2500Type EM-ILM.
The E2500-Type EM-ILM is qualified for DWDM applications to Bellcore TA-TSY-000468.

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