10Gb/s EA Modulator
and DFB Laser with
coplanar RF input
EA10WZD*
Specifically designed for use in Long and Short Haul
STM-64/OC-192 TDM applications over 40km and
80km with low dispersion penalty (less than 2dB).
This device is available in a hermetic 14-pin
ceramic butterfly package with 50
coplanar infeed for modulation input.
Features
High output power

Long haul performance with
negligible dispersion penalty
Single 50
low voltage drive
modulation input
Integral thermo-electric cooler
with precision NTC temperature
control
Hermetically sealed 14-pin butterfly
package with optical isolator
Applications
Suitable for use:
In SONET & SDH (~ 9.953Gb/s)
As a Digital Wrapper (~ 10.3Gb/s)
With FEC (~ 10.7Gb/s)
With MetroCorTM and standard
SMF-28TM fiber
