Precautions
• Make sure the fiber connector and fiber type match the transceiver module type.
• The optical interfaces on some cards have shielded covers. Remove the shielded covers before
using the optical interfaces. Optical interfaces must be installed with shielded covers when they
are not in use. Keep them safely.
• Fiber connectors must be protected under safe and reliable outer packing, and be fitted with dust
caps. Fiber connectors must be installed with dust caps when they are not in use. Take care not to
scratch their end face. Replace the dust cap if it is loose or polluted.
• Before connecting a fiber, use dust free paper and absolute alcohol to clean the end face of the
fiber connector. You can brush the end face only in one direction. You also need to brush the end
face of the fiber port.
• Never bend or curve a fiber when connecting it. After a fiber is installed well, the bend radius must
be not less than 10 cm (3.94 in).
• If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted
surface (the filleting radius must be not less than 2 mm, or 0.08 in). When passing through a
