These are absolute stress ratings only. DEFINITIONS Twave Twave is the submount temperature at which the laser emission wavelength reaches the target wavelength with an accuracy o better than: λ target ± 0.1 nm. This temperature is calculated during manuacturing according to: Twave = 25 C + (1/C)*(λ target - λ 25 C ), where C is the laser wavelength drit with temperature (in nm/ C). Emitted Wavelength Drit vs Tcase Absolute value o maximum emitted wavelength deviation per unit o case temperature ( C) when Tcase varies rom min to max operating conditions. Wavelength is stabilized through the thermal regulation o the laser chip based on the thermistor reading. Emitted Wavelength Drit vs Twave Maximum emitted wavelength deviation per unit o submount temperature ( C) when Tsubmount varies rom min to max conditions. Wavelength is stabilized through the thermal regulation o the laser chip based on the thermistor reading. 2

Hazard warning label (ESD) 6. Laser Saety Class Label Deliverable Data The ollowing data shall be supplied with each device: 1. L(I)/V(I) Tc/ Tsubmount = 25 C/25 C 2. I t, V Tc/Tsubmount = 25 C/70 C, P 3. Values o Twave and R Tsubmount = Twave 4. Values o I, I m, I th and external dierential Tsubmount = Twave and P 5. λ and SMSR at Tc = Tsubmount = 25 C Product testing shall be carried out at a level that ensures conormity to the customer speciication. SAFETY AND HANDLING Saety and IEC.825 Classiication Take appropriate precautions to prevent undue exposure to naked eye. This product is classiied Class 3B Laser Product according to IEC.825. Handling This product, in line with all similar devices, is sensitive to electrostatic discharge. Take precautions to prevent ESD; use wrist straps, grounded work suraces and recognized anti-static techniques when handling the laser. Handle the laser module by its package only, never hold it by leads or pigtail. For package mounting the ollowing procedure should be careully ollowed: 1. In order to achieve the ultimate thermal perormance o the device, thermal paste can be useully added on the support 2. Tighten screws up to 200 mn/m - Do not exceed this mounting torque. 3. Assure that the leads are aligned and in contact with appropriate contact pads. Care should be taken to avoid supply transient and over voltage. Over voltage above the maximum speciied in absolute maximum rating section (table 2) may cause permanent damage to the device. 4
