10 Transport
Flexi Lite BTS uses IP/Ethernet as a standard transport protocol. Ethernet, both wireline
and fiber, is the standard interface in Flexi Lite BTS. Flexi Lite BTS provides various
transport options.
Wireline Ethernet
Flexi Lite BTS Base Module RJ45 socket supports 1 Gigabit Ethernet copper interface
100/1000 Base-T according IEEE802.3 clause 40.
Fiber Ethernet
Ethernet SFP interface (100 and 1000 Base-x) is based on MSA INF-8074 specification.
Both multi-mode and single-mode fibers are supported. Optional SFP modules are
available according to the different requirements in the actual site implementation. Fiber
SFP module options:
•
1000BASE-SX up to 550m
•
1000BASE–LX up to 10km
•
1000BASE-BX up to 40km
QoS-aware Ethernet switching allows cascading BTSs on the same site (collocation) or
across different sites (transport chaining) through electrical or optical Ethernet port.
Flexi Lite BTS can also provide the power to an external device if it meets the P+E power
supply requirements. Ethernet wireline interface supports power output P+E from Flexi
Lite BTS to external devices, for example microwave radio link. The voltage is -48V DC
with maximum 38 W power.
Note that P+E is a NSN proprietary power feeding solution over Ethernet. Standard PoE
(IEEE802.3at and IEEE802.3af) can be provided by an external power device.
