x Installation and Service GuideLaser Safety InformationNote: The Optical Link Card (OLC) referred to in this information is part of the Serial OpticChannel Converter assembly.This system contains a laser product called the Optical Link Card (OLC). In the U.S., theOLC is certified as a Class 1 laser product that conforms to the requirements contained inthe Department of Health and Human Services (DHHS) regulation 21 CFR Subchapter J.Internationally, the OLC is certified as a Class 1 laser product that conforms to therequirements contained in the International Electrotechnical Commission (IEC) standard 825(1984), the Verband Deutscher Elektrotechniker (VDE) standard 0837 (1986), and theCENELEC (European Committee for Electrotechnical Standardization) HarmonizationDocument HD 482 S1 (1988). The German testing institute VDE assigned a certificate ofconformity to DIN IEC 825/VDE 0837/02.86 and CENELEC HD 482 S1/03.88; the certificateregistration number is 3642.In addition, Statens Provningsanstalt (Swedish National Testing Institute) tested andapproved the OLC for use in Sweden as a Class 1 laser product and assigned the approvalnumber SP LA 89:184. The CDRH certification label and the VDE certificate of conformitymark are located on the plastic retainer of the OLC product. Figure 1 shows the systemClass 1 information label required by IEC 825.Class 1 laser products are not considered to be hazardous. The OLC internally contains agallium aluminum arsenide (GaAlAs) semiconductor laser diode emitting in the wavelengthrange of 770 to 800 nanometers. This laser diode is a Class 3B laser that is rated at 5.0milliwatts. The design of the OLC is such that access to laser radiation above a Class 1level during operation, user maintenance, or service conditions is prevented.CLASS 1 LASER PRODUCTLASER KLASSE 1LUOKAN 1 LASERLAITEAPPAREIL A LASER DE CLASSE 1TO IEC 825:1984/CENELEC HD 482 S1Figure 1. Class 1 System Information Label Required by the IEC 825 StandardThe Optical Link Card (OLC) must only be connected to another OLC or a compatible laserproduct. Any compatible laser product must contain the open fiber link detection and lasercontrol safety system used in OLC. This is a requirement for correct operation of the opticallink. In addition, the OLC product is designed and certified for use in applications withpoint-to-point optical links only. Using this product in any other type of optical linkconfiguration (for example, links containing optical splitters or star couplers) is consideredas not using the product correctly and may require that the user certify the laser productagain for conformance to the laser safety regulations.
