DWDM systems

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 Gb/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

the TriQuint 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. TriQuint is providing devices compatible

with the ITU-T wavelength standards.
