3.2.3 Optic port Cleaning
 We recommend that optic connector should be cleaned using a dry optical cleaning swab or tissue in a dry
environment before connecting optic cable. Also, if the expected optic loss is 1.5dB higher than the loss
reported in the Web-GUI, the optic loss should be minimized through cleaning optic connectors.(Figure 3-3)
 The unused optic ports are should be covered with a protective dust cap. (Figure 3-4)
