Description:
The TLCN4, bidirectional 4-way
splitter/combiner, provides two identical
combining sections for UL and DL which can
be used to:
¾ combine 4 RF signals into a common
RF output
¾ split an RF input into 4 RF output
signals
It is a passive wideband module.
RF ports:
• 1 DL common RF port (“C”)
• 4 DL splitted RF ports (labelled
“1”,“2”,“3”,“4”)
• 1 UL common RF port (”C”)
• 4 UL splitted RF ports (labelled
“1”,“2”,“3”,“4”)
Note
: each port is bidirectional.
TLCN4 main applications
Main applications of the TLCN4 module are:
• Connecting a donor source to more than
one TFLN master optical TRX, so that:
¾ TLCN4 splits the DL input coming
from a donor source into 4 output
signals entering 4 different TFLN
master optical TRX
¾ TLCN4 combines the UL inputs
coming from 4 TFLN master optical TRX into 1 common signal
entering the donor source
• Connecting a TFLN master optical TRX to more than one donor source
within the same service, so that:
¾ TLCN4 combines the two DL inputs coming from up to 4 donor
sources into 1 output signal entering the TFLN master optical TRX
¾ TLCN4 splits the UL inputs coming from TFLN master optical TRX into
4 different output signals entering up to 4 different donor sources
More TLCN4 modules can be used in cascade connections.
