5.1.6 Optical Cabling
HROU makes optical-electronic conversion of TX signals from upper ODU and OEU and makes
electronic- optical conversion of RX signals. HROU 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. HROU has SC/APC of optical adaptor
type.
For optical adaptor, SC/APC type can be used only. To prevent the optical access part from
being marred by dirt, it should be covered with a cap during moving. Befoe optical cable put it
on optical port, you need to clean up them using alcohocol to remove dirt.
Optical cable port support water-proof type. Therefore, to prevent it from water and dirt you
should install as procedures below
