3.1.3 Optical Cabling
MRU makes optical-electronic conversion of TX signals from upper ODU and OEU and makes
electronic- optical conversion of RX signals. MRU has one optical module in it. As WDM is installed in
the R_OPT module, two pieces of wavelength (TX:1310nm, RX:1550nm) can be sent/received with
one optical strand at the same time. MRU 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 are recommended to clear them using alcohocol to remove dirt.
