Optical cables should be inserted into Optic Port outside of ROU. Using an optical slack devices
in ROU, you need to coil around one or two roll of cables to be connected with the optical
adaptor of ROPTIC.
At this time, curvature of the optical cable should be at least 10Ø to prevent insertion loss from
being increased.
Through GUI, check if PD value of ROPTIC is in a tolerable range (+4~-1dBm).
5.3.4 GND Terminal Connection
ROU has one GND terminal port where is on bottom side, like below
- Take off the GND terminal port from enclosure and connect to ground cable, then fix it
the position of enclosure again
- The opposite end of the ground cable should connect to the communication GND of
building
- The ground lug is designed meeting the SQ5.5 standard
5.3.5 Coaxial cable and Antenna Connection
- The coaxial cables which are connected to antenna distribued network connect to
antenna port of ROU. Before connection, check the VSWR value of coaxial cable
whether it is within specification using SITEMASTER .
- At this time, check if the Return loss have above 15Db or VSWR have below 1.5
- The part of antenna connection fasten to port not to be loosed and not to be injected
the dusty and insects
- The antenna connected to ROU is only serviced in inbuilding
5.3.6 Insertion of RDU
ROU has slots to enable up to three RDU modules to be inserted into the unit.
