10Gb/s DWDM EA Modulator and DFB Laser with
GPO RF Connector
EML10WCB
The Bookham EML10WCB Laser has an electro-absorption
modulator monolithically integrated with a conventional
Distributed Feedback Multi Quantum Well (MQW) laser.
This allows the modulation voltage to be applied to the
modulator section whilst the laser section operates CW
allowing extremely low wavelength chirping. Specifically
designed for use in STM-64/OC-192 DWDM 100GHz
applications over 80km, with low dispersion penalty at
9.953Gb/s, (<2dB). A high extinction ratio of >10.5dB.
This device is available in a hermetic 7-pin ceramic butterfly
package with SMP/GPO connector for modulation input.
The EML10 includes an optical isolator, monitor photodiode,
thermistor and thermo-electric cooler.
