anti-corrosion requirements are as follows:
1.
2.
3.

2.5 Working Wavelengths

The working wavelengths of the ZXMP M600 equipment are in strict compliance with
ITU-T Recommendation G.694.2. Specific central wavelengths and central frequencies
used in a multi-channel system are adopted.

Table 2.4-1 Temperature and Humidity Requirements

There should be no explosive, conductive, magnetic-conductive or corrosive
dust in the transmission equipment room.
The density of the dusts with a diameter greater than 5µm should be less or
4
equal to 3×10 particle/m
There should be no such gas as SO
the insulator.
The equipment should be kept clean. Besides, the door and the windows should
be sealed.
