About this document

This document provides a comprehensive overview of all necessary tasks of the HCS (Hybrid Connectivity System) installation. It includes a step-by-step-guide that explains how to handle and assemble all necessary piece parts.

Abstract:

The Hybrid Connectivity System contains of a male Hybrid Connector, a female Hybrid Connector, and a Fixing Bracket

The HCS is meant to feed up to 4 RRU´s with a single Hybrid Riser cable and the according number of Hybrid Jumpers

The HCS combines F/O and DC connectivity in one single connector

For easy installation even with unfavorable cable positions, the mating part of the male Hybrid Connector is twistable.

Stacked fixation levels to ease connector installation and prevent mix up of connectors

Note:

These instructions are written for

qualified and experienced

installation personnel.

Please read this document

carefully before starting any work.

Any liability or responsibility for

the results of improper or unsafe

installation is disclaimed.

Please respect valid

environmental regulations for

assembly and waste disposal.

Always use appropriate personal

protection and observe all work

safety and security precautions in

accordance with local regulations

during installation.

1. Content of System

a. Female Hybrid Connector

The HYBRIFLEX™ cable coming from the BBU is equipped with a female Hybrid Connecter with touch protected contacts. The DC contact is built as a socket type connection to avoid contact to current-carrying parts.

A Dust cap (IP 67) protects the connector´s mating face during storage, transport, installation… shortly: whenever it is not coupled. Female Connector (with Dust cap)

A red dot indicates the mating face direction. The mating part of the female Hybrid Connector is twistable to ease installation even under unfavorable cable positions.

Caution:

For removing the dust cap,

keep the cap steady and turn

the swivel nut.

b. Male Hybrid Connector

The HYBRIFLEX™ cables going to the RRU are equipped with a male Hybrid Connecter with touch protected contacts. The DC contact is built as a plug type connection.

A Dust cap (IP 67) protects the connector´s mating face during storage, transport, installation… shortly: whenever it is not coupled.

A red dot indicates the mating face direction. Male Connector (with Dust cap)

A cap nut allows bulkhead fixation to the Fixing Bracket

c. Fixing Bracket

The Fixing Bracket contains of four mounting holes stacked in four height levels to avoid mixed up connections.

The device will be installed to an antenna pipe by means of the counter clamp

and the two M12 x 120 bolts

2. Installation sequence

a. Fixing bracket

Mount Fixing Bracket to the antenna pole by means of the two M12 x 120 bolts and nuts.

The correct position is determined by the pre-installed HYBRIFLEX™ jumpers.

A torque of 40 Nm has to be applied

Tools required: two 19mm open ended spanners

b. Fixing of male Hybrid Connector

Caution:

Before doing any connector

work with the hybrid jumpers,

fix them temporarily to avoid

any mechanical stress on the

connectors.

Remove dust cap of male Hybrid Connector.

Keep dust cap safe for re-use in case the Hybrid connector is disconnected again.

Very important for portable

and temporary solutions!

Remove cap nut of male Hybrid Connector.

The cap nut will be used later on to fix the Hybrid Connector to the fixing bracket.

Push connector from above through corresponding hole in Fixing Bracket.

Fix male Hybrid Connector of HYBRIFLEX™ jumper to mounting holes of the Fixing Bracket by means of the bulkhead cap nuts.

A torque of 20 - 23 Nm has to be applied

Tools required: two 34mm open ended

spanners

Caution:

Re-attach dust caps of Hybrid Connector for the period the jumper is not connected to the riser

Caution:

Make sure that the red dots of

all four connectors point into

the same direction!

Red indicator dots

In case not all Hybrid Connectors of the riser cable are used for a period of time, they have to be sealed properly.

Do not use the plastic dust caps in this case.

Use the metal IP68 sealing caps which also provide a fixation of the Hybrid connectors to the Fixing Bracket.

c. Fixing of HYBRIFLEX™ jumper

After all connectors are mounted to the Fixing Bracket make sure all jumper cables are well fixed to the antenna pole using appropriate installation material.

e.g. with round member adapter (RMA-xxx) and RSP Clips (RSB-12)

d. Fixing of female Hybrid Connector

Caution: Before doing any connector

work with the HYBRIFREX™

Riser cable, fix it temporarily

to avoid any mechanical

stress on the connectors.

The breakout parts of the HYBRIFLEX™ Riser cables are pre-connectorized in different lengths, corresponding to the levels of the stacked Fixing Bracket. Start with the connector of the shortest breakout cable of the HYBRIFLEX™ Riser cable.

Caution: Make sure to align the red

indication dots of both

connectors (male and female)

to ensure a proper mating. If

necessary turn mating part of

connector into right position.

The mating part of the female connector can easily be turned manually without any special tool.

Connect both connectors and secure the female connector by means of the swivel nut. Tighten nut with spanner.

A torque of 20-23 Nm has to be applied

Tools required: two 34mm open ended spanners

Continue with the next longer breakout cable of the HYBRIFLEX™ Riser cable until all four cables are connected.

Secure the connection by mean of the swivel nuts of the female connectors.

Tools required: two 34mm open ended spanners

e. Final fixation of the HYBRIFLEX™

Riser cable

Fix the HYBRIFLEX™ Riser cable to the antenna pole by means of appropriate installation hardware (e.g. round member adapter with RSB clip).

f. Opposite end connections

At the opposite end of the HCS connectors (Top, to the RRU / Bottom to the BBU) there are most likely LC or SC F/O connectors. These connectors are on first delivery equipped with dust caps. Every time these connectors are disconnected and stored for later re-use the have to be

protected again with new dust caps.

g. F/O connector cleaning

Before each coupling of F/O connectors the surface of the ferules have to be cleaned. As cleaning tool for HCS Male and Female connectors is a standard LC connector bulkhead cleaner for 1.25mm ferrules (e.g. USCONEC P/N 9393 - IBC™ Brand Cleaning Tool for LC and MU Connectors) recommended.

h. Weather protection

For disconnected and stored F/O or DC cables, there are special Connector Protection Device (CPD) available.

CPD (F/O) Model Name: HS-CPD-105-000-E1

CPD (DC) Model Name: HS-CPD-000-110
