Maintaining SFP+ and QSFP+ Transceivers and Fiber-Optic
Cables
SFP+ and QSFP+ transceivers and fiber-optic cables must be kept clean and
dust-free to maintain high signal accuracy and prevent damage to the connectors.
Attenuation (loss of light) is increased by contamination and should be below 0.35
dB.
Follow these maintenance guidelines:
