Cleaning Information What do I need for proper cleaning? Furthermore, the power density may burn dust into the fiber and cause additional damage (for example, 0 dBm optical power in a single mode fiber causes a power density of approximately 16 million W/m2). If this happens, measurements become inaccurate and non-repeatable. Cleaning is, therefore, an essential yet difficult task. Unfortunately, when comparing most published cleaning recommendations, you will discover that they contain several inconsistencies. In this section, we want to suggest ways to help you clean your various optical devices, and thus significantly improve the accuracy and repeatability of your lightwave measurements. What do I need for proper cleaning? Some Standard Cleaning Equipment is necessary for cleaning your instrument. For certain cleaning procedures, you may also require certain Additional Cleaning Equipment. Standard Cleaning Equipment Before you can start your cleaning procedure you need the following standard equipment: • Dust and shutter caps • Isopropyl alcohol • Cotton swabs • Soft tissues • Pipe cleaner • Compressed air Dust and shutter caps All of Agilent Technologies’ lightwave instruments are delivered with either laser shutter caps or dust caps on the lightwave adapter. Any cables come with covers to protect the cable ends from damage or contamination. 92 Agilent 81610A/11A/12A/13A/14A Return Loss Module, Fifth Edition
