1) The OLT TX1-2 connect DS to either East or
West DWDM MUX
2) The OLT RX1-2 connect US to either East or
West DWDM DEMUX
When the protection and monitoring system isused the connections go via it.
3) There is a pre-amplifier (PA) upstream for allwavelengths before the DWDM DEMUX.
There is also a boost amplifier (BA)downstream for all wavelengths after
the DWDM MUX.
4) DS and US fiber spools (5-25km) run between
the OLT and the RN1-2
1) CPE STBs connect to ONU High defintion video service
port (HD-sp).
2) The ONU1-2 MAC connects to TXb1-2 via SMA cabling.
3) The ONU1-2 MAC RX connects to RX1-2 with fiber.4) TXb1-2 connects to drop fibers (2-5km).
5) Drop fibers go to splitters 1-2 which connect to feeder
fibers.
6) Feeder fibers (5-15km) connect to the RN1-2.

The services and management connect to the
Service switch 1GE ports (on the back).
1) Service switch connects to OLT1-OLT2 MAC via
10GE (CX4) ports.2) OLT1-2 MAC connects to TX1-TX2 downstream
transmitters via fiber.
3) TX1-TX3 connect via multiplexers to thedownstream ring fibers.
4) OLT MAC RX1-2 connect from upstream ringfibers via demultiplexers

SARDANA efficiency traits
Cost efficiency: SARDANA average CAPEX is 15-20%less compared to GPON.
Scalability, future needs coverage guarantee
Space savings
Efficient use of fiber resources:
Design flexibility, granularity
Feeder and distribution part shared among a muchlarger number of end-users than in any other
technology. Savings in OPEX and maintenance.
SARDANA2 bears great power efficiency over thelargest interval, consuming only about 3 W/Gbps.
