an industry-standard, 14-pin butterfly package. The
between regenerators is in the range of 150 km鈥?/div>
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.鈥檚 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
鈩?
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.
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.
