System Overview (branched parts)


LT (Top) is the stripped part of the Hybrid cable near to the RRH most probably

with factory installed F/O and Power connectors

LB (Bottom) is the stripped part of the Hybrid cable near to the BBU

The lengths can be adjusted to customers need (typical lengths are 3 8 m)

Jacket and outer conductor can be easily stripped back on site by means of

the integrated ripcord; final cross cut with RFS Trimming Tool

Connectorization


Transition Hybrid to individual cables

Connectorization is done in the factory (optical measurement on every pre-assembled cable)

LC Connectors for factory- and field installation, ODC Connectors and other solutions on request

Power connectors according to customers requirement

Individual PE jackets on each F/O and power cable pair (marked with FO01FO03 and EL01EL03) Allows direct connection to the RRH / BBU without any connection boxes

System Overview (branched parts)


Pre conectorized F/O and power cables may lead to over lengths which can be handled as follows

Buffer - Box

Loop cables

A Buffer Box can host up to 15m of individual

F/O or Power pairs

Over length

Wind a loop out of the over length and fix it to

the RRH supporting pole
