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).
3.1.4 GND Terminal Connection
L2ROU 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
3.1.5 Coaxial cable and Antenna Connection
- The coaxial cables which are connected to antenna distribued network connect to
antenna port of L2ROU. 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
