Optical Cabling
N2ROU makes optical-electronic conversion of TX signals from upper ODU and OEU and
makes electronic- optical conversion of RX signals. N2ROU has one optical module in it. As
WDM is installed in the R_OPTIC module, two pieces of wavelength (TX:1310nm, RX:1550nm)
can be sent/received with one optical core at the same time. N2ROU has SC/APC of optical
adaptor type.
For optical adaptor, SC/APC type can be used. To prevent the optical access part from being
marred with dirt, it should be covered with a cap during move. When devices are connected
through optical cables, you need to clear them using alcohocol to remove dirt.
Optical cables should be inserted into Optic Port outside of N2ROU.
Through GUI, check if PD value of ROPTIC is in a tolerable range (+5~1dBm).

GND Terminal Connection
N2ROU has one GND terminal port where is on bottom side, like below
