BOOKHAM EML10W5575CB-J59

Data Sheet
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.
Features:
• High output power
• Low modulation voltage
• Long haul performance with negligible
dispersion penalty
• Single 50Ω low voltage drive modulation input
• Integral thermo-electric cooler with precision NTC
temperature control
• Hermetically sealed 7-pin butterfly package with
optical isolator
• High stability laser chip
• No wavelength locker required
• High extinction ratio >10.5dB
• RoHS compliant
Applications:
• Suitable for use:
• In DWDM FEC applications (~ 10.709Gb/s)
• In DWDM applications (~ 9.95Gb/s)
• ITU-T standard 100GHz grid
• C brand (1529.55nm to 1561.42nm)
• With MetroCor™ and standard SMF-28™ fiber
80km applications

Reliability
Bookham has a corporate policy for continuous improvement, to provide optical components with superior quality in terms of
opto-electronic performance and operational life and reliability. The Bookham EML10 and EML11 Integrated Electro-absorption
laser products use a ridge waveguide structure for the laser and modulator, which provides superior reliability compared to buried
heterostructures. It has been subjected to a stringent reliability assurance program, the conclusions of which confirm product
reliability exceed the generic requirements of Telcordia GR-468 CORE.
More than 965,000 device-hours of data under accelerated life test conditions have been analysed, which for the purpose of
characterising random failure rate, is equivalent to 28,300,000 device hours at 25ºC operating temperature [7]. Electro-optic
parameters for a 15 year service life at operating temperature of 25ºC have been estimated. The estimated delta over life for
specific device parameters is shown in the table below.

The reliability failure rate statistics are summarized in the table below. The results are reported for the operation of the device
against a laser bias of 100 mA drive current. The resultant low MTTF [8], essentially demonstrating minimal component wear out
over the rated 15-year lifetime of the component [7].
