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

ÿ the TLCN4 combines the two DL inputs coming from up to 4 donor sources
into 1 output signal entering the TFLN master optical TRX.
ÿ the TLCN4 splits the UL inputs coming from the TFLN master optical TRX into 4
different output signals entering up to 4 different donor sources.
