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

■ High-speed data communications

■ Digitized video

Description

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, the newest generation of the award-

winning 266-Type EM-ILM, features an integrated modulator

and laser chip, and provides a compact, cost-effective solu-

tion for extended-reach transmissions.

Features

■ Integrated electroabsorptive modulator

■ 1.5 µm wavelength

The E2500 EM-ILM can replace external modulators

in many applications. The nominal input impedance

for the modulator is 50 Ω. By integrating the

■ Characterized for 2.5 Gbits/s operation

■ Very low dispersion penalty over 600 km

■ Low modulation voltage

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.

■ Temperature stabilized

■ Wavelengths selectable to ITU-T standards

■ Ultrastable wavelength aging performance for

DWDM systems

Description

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.

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 operations section of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.

Operation at a DT of 70 °C – TSET is guaranteed, where TSET is the laser temperature required to achieve the required ITU wavelength,

over life, in a DWDM system (TSET range is 15 °C to 35 °C). In a non-WDM application, TSET is 25 °C.
