6 MAINTENANCE
Use maximum care in handling optical fiber cables. To avoid breakage, do
not reduce the bending radius to 30 mm or less.
Clean the optical module receptacle and optical connectors after
measurement.
Because the SD.LINK module (LQE530) uses a Type SC (or 2SC) optical
connector, the optical power meter must support Type SC (or 2SC)
accordingly. Use a Type SC (or 2SC) connector adapter (included with the
optical power meter or sold separately).
