Data Sheet 10Gb/s EA Modulator and DFB Laser with GPO RF Connector EML10ZCA The Bookham EML10 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 TDM applications over 40km, with low dispersion penalty at 9.953Gb/s, (<2dB). A high extinction ratio of 10dB. 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 extinction ratio >10dB • RoHS compliant Applications: • Suitable for use: • In SONET & SDH applications (~ 9.95Gb/s) • With MetroCor™ and standard SMF-28™ fiber 40km applications MetroCor™ and SMF-28™ are registered trademarks of Corning Incorporated 1 Data Sheet Characteristics Tcase = 25°C, Tlaser = 25°C unless otherwise stated Parameter Conditions Min Typ Max Unit 5 20 35 mA 0.001 1 uW 80 90 mA 100 mA 2 V 1530 1563 nm -100 100 pm CW Laser Threshold current Threshold power Operating current SOL @Iop 50 Operating current EOL @Iop Laser forward voltage If=80mA @ 25°C, CW Peak wavelength Wavelength drift vs life time 15 years typical life Side mode suppression ratio (SMSR) @ Iop Spectral width @ Iop -20dBr, Note  1.2 36 45 0.2 0.27 dB 0.3 nm Optical Modulator Modulator drive voltage 2 2.8 Vpp Bias voltage for ‘on’ level -0.7 0 V Fibre output power Note Case temperature tracking error Tcase = -20 to +70 °C  S21 Optical bandwidth 2 -1 0.5 2 dBm -0.5 +/-0.1 0.5 dB 8 12.5 GHz S11 return loss (0 GHz to 7 GHz) -15 -8 S11 return loss (7 GHz to 10 GHz) -10 -5 15 20 30 dB Optical rise/fall time 20 to 80%, Notes Dynamic optical extinction ratio Notes   10 11 dB OC192/SDH64 mask margin Notes   15 25 % Dispersion penalty (RX power penalty) Notes     0.5 1.7 ps dB Data Sheet Characteristics (continued) Parameter Conditions Min Typ Max Unit 1 5 10 V 0.2 0.85 1.5 mA 0.001 0.1 uA 15 pF 10.5 kΩ Photodiode Monitor Monitor diode bias voltage Monitor diode current Note  @Iop Dark current Capacitance Thermo Electric Cooler System Thermistor resistance @ Tsub=25degC 9.5 10 Thermistor Steinhart-Hart coefficient C1 1.03E-03 Thermistor Steinhart-Hart coefficient C2 2.39E-04 Thermistor Steinhart-Hart coefficient C3 1.56E-07 Thermistor B constant 0/50k 3539 3575 3611 Thermistor current 1 10 100 uA Laser submount temperature 20 25 35 °C TEC current (EOL) 1.3 A TEC voltage (EOL) 2.5 V TEC power dissipation 3.3 W Other Optical isolation Tcase = -20 to +70 °C Fibre Length 25 0.8 Notes:  Applied modulation is 9.95328Gb/s, 2^23-1 PRBS NRZ data sequence.

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 . 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. Parameter Maximum allowed change Change over 15 years @ 25 °C Mean (std. deviation) EA - Extinction rate ER 0.5 dB Laser threshold current 10 % 0.01 % (0.3 %) Laser efficiency 10 % -0.2 % (0.4 %) Laser current for constant output power 10 % 0.2 % (0.4 %) Laser power at constant current (100 mA) 10 % -0.2 % (0.4 %) -0.03 dB (0.2 dB) 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 , essentially demonstrating minimal component wear out over the rated 15-year lifetime of the component .
