FIBER SCENARIO
➢ Frequency Synch
SyncE - Clock is recovered from the WAN interface and propagated to the 1GBE UNIs
➢ Time/Phase
1588v2 Agnostic
1588v2 Boundary clock –
✓ The Control Unit act as a 1588 Slave port and recovers the time and phase info
✓ The Control Unit then operates as Master Clock for the P2P 1GBE ports (the timestamp is made by the Ethernet Phy )
SAMBHA 200 and Mobile Backhauling Synch
SAMBHA 200 is ready to propagate the Mobile Network Synchronization towards the radio base stations thanks to its SyncE
compliancy for the nodes that just need the Frequency Sync or/and thanks to the IEEE 1588v2 for the nodes that need also
Time/Phase Sync. This can be optained either on Fiber as well as on Copper scenario:

SAMBHA can be easily integrated in the following Network Management paradigm thanks to the adoption of standard
protocols and interfaces like SNMP, HTTP, SQL. A dedicated Element Manager is also envisaged in the Network
Management umbrella.

premises (FTTH) but it can arrive close to the home and use G.fast to deliver
speeds up to 1 Gigabit per second (Gbps) over the existing copper line.
It is composed of a unique body with the following characteristics:
➢ IP55/IP68 protection degree (according to the installation required)

selta.com
SAMBHA 48C – Deployment Scenarios: on Top of cabinet
SAMBHA 48C, as well as SAMBHA 200, can be easily positioned on the top of existing
passive street cabinets thanks to the adoption of a special kit (Cap Kit) that seamlessly
can be adapted on the top of cabinets, no matter if they are plastic or metal built.
In a space of less than 70x22 cm, both the ONU and the local or remote power feeder
can be allocated, then covered with a small red shell. Moreover, thanks to a patented
system, the Cap Kit can slide in a different position to facilitate cabling and
maintenance operations. A tamper resistant system-lock inside the cabinet assures
that only authorized people can access.
27

selta.com
SAMBHA 48C – Deployment scenarios: Manhole
SAMBHA 48C can be easily placed in manholes thanks to the ONU and the local or
remote power feeder which are designed to be IP68 proof and certified. Thanks to this
design any potential flood in the manhole is definitely not an issue.
The real small footprint of SAMBHA 48C allows network operators to reuse empty
spaces in existing manholes or, at worst, to dig new ones without the need to obtain
large spaces.
An appropriate shell helps to mount ONUs upon manhole walls and external walls of
public or private buildings.
28

selta.com
SAMBHA 48C – Deployment Scenarios: on Pole
To maximise the adoption of SAMBHA in all scenarios, a special kit has been designed
for pole-mounting, where both the ONU and the local or remote power feeder can be
easily placed. Whenever it’s not easy or convenient to get electrical power on site,
power can be feeded directly from the central office. SAMBHA plays therefore an
important role in facilitating VDSL deployment.
