| 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 50 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 MetroCorTM and standard SMF-28TM fiber 40km applications MetroCorTM and SMF-28TM are registered trademarks of Corning Incorporated 1 Data Sheet Characteristics Tcase = 25C, Tlaser = 25C unless otherwise stated Parameter CW Laser Threshold current Threshold power Operating current SOL Operating current EOL Laser forward voltage Peak wavelength Wavelength drift vs life time Side mode suppression ratio (SMSR) @ Iop Spectral width @ Iop Optical Modulator Modulator drive voltage Bias voltage for `on' level Fibre output power Case temperature tracking error S21 Optical bandwidth S11 return loss (0 GHz to 7 GHz) S11 return loss (7 GHz to 10 GHz) Optical rise/fall time Dynamic optical extinction ratio OC192/SDH64 mask margin Dispersion penalty (RX power penalty) 20 to 80%, Notes Notes Notes Notes [1] [3] [1] [3] Conditions Min Typ Max Unit 5 20 0.001 35 1 90 100 mA uW mA mA V nm pm dB @Iop @Iop If=80mA @ 25C, CW 50 80 1.2 1530 2 1563 100 15 years typical life -100 36 45 0.27 -20dBr, Note [2] 0.2 0.3 nm 2 -0.7 Note [1] 2.8 0 0.5 +/-0.1 12.5 -15 -10 -8 -5 30 2 0.5 Vpp V dBm dB GHz dB -1 -0.5 8 Tcase = -20 to +70 C 15 10 15 20 11 25 0.5 ps dB % [1] [3] [1] [4] 1.7 dB 2 Data Sheet Characteristics (continued) Parameter Photodiode Monitor Monitor diode bias voltage Monitor diode current Dark current Capacitance Note [1] Conditions Min Typ Max Unit 1 @Iop 0.2 5 0.85 0.001 10 1.5 0.1 15 V mA uA pF Thermo Electric Cooler System Thermistor resistance @ Tsub=25degC Thermistor Steinhart-Hart coefficient C1 Thermistor Steinhart-Hart coefficient C2 Thermistor Steinhart-Hart coefficient C3 Thermistor B constant Thermistor current Laser submount temperature TEC current (EOL) TEC voltage (EOL) TEC power dissipation Other Optical isolation Fibre Length Tcase = -20 to +70 C 25 0.8 30 1.2 dB m 0/50k 3539 1 20 9.5 10 1.03E-03 2.39E-04 1.56E-07 3575 10 25 3611 100 35 1.3 2.5 3.3 uA C A V W 10.5 k Notes: [1] 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 25C operating temperature [7]. Electro-optic parameters for a 15 year service life at operating temperature of 25C have been estimated. The estimated delta over life for specific device parameters is shown in the table below. Parameter EA - Extinction rate ER Laser threshold current Laser efficiency Laser current for constant output power Laser power at constant current (100 mA) Maximum allowed change 0.5 dB 10 % 10 % 10 % 10 % Change over 15 years @ 25 C Mean (std. deviation) -0.03 dB (0.2 dB) 0.01 % (0.3 %) -0.2 % (0.4 %) 0.2 % (0.4 %) -0.2 % (0.4 %) 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]. Parameter Median life (ML) at 25C (standard deviation of the natural logarithms of the TTFs) (mean of the natural logarithms of the TTFs) Maximum wear-out failure rate Average wear-out failure rate over 15 years life Wear-out thermal activation energy Random failure rate at 25C at 60% confidence Random failure rate activation energy Notes: Value 528(1) 0.64 6.27 0 0 0.5 33 0.35 Units Years FITs FITs eV FITs eV [7] Refer to QR1524, qualification report for the Bookham 10Gb/s Electro-Absorption Modulated Laser. [8] Bookham Technology's policy is to derive random failure rates from actual field data. 7 Data Sheet RoHS Compliance Bookham is fully committed to environment protection and sustainable development and has set in place a comprehensive program for removing polluting and hazardous substances from all of its products.
