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 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 µW 80 100 mA 105 mA 2 V 1529.55 1561.42 nm -100 100 pm Wavelength stability with case temperatures -0.5 +0.5 pm/°C Side mode suppression ratio (SMSR) @ Iop 36 45 0.2 0.27 0.3 nm Modulator drive voltage 2 2.5 2.8 Vpp Bias voltage for ‘on’ level -0.5 -0.2 0 V -3 -2 -1 dBm 0.5 dB CW Laser Threshold current Threshold power Operating current SOL @Iop Operating current EOL @Iop Laser forward voltage If=80mA @ 25°C, CW 50 Peak wavelength Wavelength drift vs life time Spectral width @ Iop 15 years typical life -20dBr, Notes [2] [1] 1.0 1.2 dB Optical Modulator 2 Fiber output power Note Case temperature tracking error Tcase = -20 to +70°C @ cont Im -0.5 +/-0.1 S21 Optical bandwidth VEA @-1V 9 12.5 S11 return loss (0 GHz to 7 GHz) VEA @-1V -15 -8 dB S11 return loss (7 GHz to 10 GHz) VEA @-1V -10 -5 dB Optical rise/fall time 20 to 80%, Notes 20 36 40 ps Dynamic optical extinction ratio Notes [1] [3] 10.5 11 dB OC192/SDH64 mask margin Notes [1] [3] 10 15 % Dispersion penalty (RX power penalty) Notes [1] [4] [1] [1] [3] 1 GHz 2 dB Data Sheet Characteristics (continued) Parameter Conditions Min Typ Max Unit 1.0 5 10 V 0.2 0.5 1.5 mA 0.001 0.1 µA 15 pF 10.5 kΩ Photodiode Monitor Monitor diode bias voltage Monitor diode current Note [1],@Iop Dark current Capacitance Thermo Electric Cooler System Thermistor resistance @ Tsub=25°C 9.5 10 Thermistor Steinhart-Hart coefficient C1 1.03x10-3 Thermistor Steinhart-Hart coefficient C2 2.39x10-4 Thermistor Steinhart-Hart coefficient C3 1.56x10-7 Thermistor B constant 0/50k 3539 3575 3611 Thermistor current 1 10 100 µA Laser submount temperature 24 36 °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 Fiber Length 25 30 0.8 Notes: [1] Applied modulation is 9.953Gb/s, 223-1 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 [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. 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 [8], essentially demonstrating minimal component wear out over the rated 15-year lifetime of the component [7]. Parameter Value Units Median life (ML) at 25°C 528(1) Years σ (standard deviation of the natural logarithms of the TTFs) 0.64 µ (mean of the natural logarithms of the TTFs) 6.27 Maximum wear-out failure rate 0 FITs Average wear-out failure rate over 15 years life 0 FITs Wear-out thermal activation energy 0.5 eV Random failure rate at 25°C at 60% confidence 33 FITs Random failure rate activation energy 0.35 eV Notes: [7] Refer to QR1524, qualification report for the Bookham 10Gb/s Electro-Absorption Modulated Laser. [8] The Bookham policy is to derive random failure rates from actual field data. 7 Data Sheet Example EML10W5575CB-J57 is a 1555.747nm EA laser with GPO RF connector and LC fiber connector for 80km reach applications. 8 Wavelength Code Wavelength ( nm) ITU-T Frequency (THz) 2955 1529.553 196.0 3033 1530.334 3112 Wavelength Code Wavelength ( nm) ITU-T Frequency (THz) +/-0.1 4532 1545.322 194.0 +/-0.1 195.9 +/-0.1 4612 1546.119 193.9 +/-0.1 1531.116 195.8 +/-0.1 4692 1546.917 193.8 +/-0.1 3190 1531.898 195.7 +/-0.1 4772 1547.715 193.7 +/-0.1 3268 1532.681 195.6 +/-0.1 4851 1548.515 193.6 +/-0.1 3347 1533.465 195.5 +/-0.1 4932 1549.315 193.5 +/-0.1 3425 1534.250 195.4 +/-0.1 5012 1550.116 193.4 +/-0.1 3504 1535.036 195.3 +/-0.1 5092 1550.918 193.3 +/-0.1 3582 1535.822 195.2 +/-0.1 5172 1551.721 193.2 +/-0.1 3661 1536.609 195.1 +/-0.1 5252 1552.524 193.1 +/-0.1 3740 1537.397 195.0 +/-0.1 5333 1553.329 193.0 +/-0.1 3819 1538.186 194.9 +/-0.1 5413 1554.134 192.9 +/-0.1 3898 1538.976 194.8 +/-0.1 5494 1554.940 192.8 +/-0.1 3977 1539.766 194.7 +/-0.1 5575 1555.747 192.7 +/-0.1 4056 1540.557 194.6 +/-0.1 5655 1556.555 192.6 +/-0.1 4135 1541.349 194.5 +/-0.1 5736 1557.363 192.5 +/-0.1 4214 1542.142 194.4 +/-0.1 5817 1558.173 192.4 +/-0.1 4294 1542.936 194.3 +/-0.1 5898 1558.983 192.3 +/-0.1 4373 1543.730 194.2 +/-0.1 5979 1559.794 192.2 +/-0.1 4453 1544.526 194.1 +/-0.1 6061 1560.606 192.1 +/-0.1 6142 1561.419 192.0 +/-0.1 Tolerance (nm) Tolerance (nm) 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.
