Product description

The optical transmitter (OSC 100 micro) and the optical receiver (OEC 40 micro and OEC

44 micro) can be used to distribute satellite and digital terrestrial signals (FM/DAB+/digital

TV) through a single-mode bre optic cable.

The RF signal fed into the OSC 100 micro is converted into an optical signal. This optical

signal is fed through the bre optic cable to an optical network (tap/splitter/attenuator)

and thus nds the optical receiver OEC 40 micro/OEC 44 micro. The receivers will then

convert the received optical signal back into an RF signal.

The transmitter (OSC 100 micro) is equipped with loop-through outputs. Several transmit-

ters are cascaded.

The optical transmitter is also equipped with AGC (Automatic Gain Control) providing for

an automatically controlled optical output level. Therefore, no adjustment is required on

the transmitter.

The receiver (OEC 40 micro) converts the incoming optical signal into the four outputs

with xed satellite polarisation planes and an output for digital terrestrial signals thus

allowing direct connection of a multi-switch on the outputs.

The receiver OEC 44 micro converts the incoming optical signal into the four switchable

universal outputs thus allowing the digital terrestrial and the satellite signal to be made

available for four different receivers or TV sets.

System functions

Digital terrestrial and satellite signals are fed to the optical transmitter (OSC 100 micro)

which converts the electrical signals into optical signals, thus allowing distribution over

long paths using a bre-optic infrastructure.

Suitable splitters (OVC xxx) and taps (OAC xxxx) are available for distribution of the opti-

cal output signal.

Notes on planning the ﬁ bre optic system

When designing a bre optic system, it is important to consider the optical input levels to

the receiver (OEC 40 micro or OEC 44 micro). To ensure that the system fulls the required

parameters, appropriate attenuation must be calculated at each point. The optical output

power from the transmitter (OSC 100 micro) is typically +7 dBm. The input level of the op-

tical receiver (OEC 40 micro and OEC 44 micro) lies between -8 dBm and -14 dBm. This

results in an allowable attenuation of the optical network of 15 to 21 dB.

The catalogue contains a whole range of optical attenuators and taps/splitters which have

different attenuation values and enable the optimisation of the system. Please use the

Kathrein CLIKulator to plan and adjust your optical distribution network

(http://clikulator.com/kathrein).

• If directly connected without splitters or taps, attenuators must be used

between the OSC 100 micro and OEC 40 micro/OEC 44 micro. To avoid

overload, the input power on the receiver must not surpass -8 dB.

• If the quality of an input signal is not optimal or if a multi-carrier signal

must be distributed over a large coaxial distribution network, the optical

budget should be decreased.

• The level difference of a satellite transponder polarity (VL/VH/HL/HH)

should not exceed 4 dB. If the transponders have a gain slope on the

inputs of the OSC 100 micro and the level is high enough, you can use

the passive equalizer ERZ 60 in certain circumstances to adjust the

level (use one ERZ 60 for each satellite polarisation). If a long coaxial

cable is used between the LNB and the OSC 100 micro, you can adjust

the level and the gain slope (for each satellite polarisation) with the VWS

2500. If several transmitters (OSC 100 micro) are cascaded, a VWS

2500 satellite distribution amplier must be connected between the

third and the fourth OSC 100 micro and also between the fth and sixth

in the cascade. The maximum quantity is seven in the OSC 100 micro

cascade.

8 / 16

Before connecting to the receiver (OEC 40 micro or OEC 44 micro),

check the optical level of the signal on the optical ﬁbre using an opti-

cal power meter.

If the optical input signal is higher than 0 dBm, damage may be done

to the device.

Handling optical components

The OSC 100 micro transmitter and the receivers OEC 40 micro and OEC

44 micro are all tted with an optical CLIK! connector. The taps and split-

ters of the OAC and OVC series are equipped with connections for CLIK!

connectors (male).

Kathrein provides optical patch cables with CLIK! connectors in various

lengths to connect passive OAC and OVC units as well as the suitable

optical connectors ODC xxx.

Unused coaxial outputs must be terminated with an optical termination

(OTC 1) without fail. Otherwise, the proper functioning of the optical distri-

bution network cannot be guaranteed.

When dealing with optical waveguides:

Installation and disconnection of the bre optic cable to the equipment:

1. Only remove the protective cover from the connection if you want to create a new

optical link - Do not touch the front face of the connector!

2. Pay attention to the orientation (input/output) and push the connector in until it clicks

(as described in the instructions)

3. Remove the bre optic cable by pressing the latch lock and pulling the cable out.

9 / 16

4. Save the protective caps to protect the connectors of the cables/devices when

removing or remodelling.

5. The minimum allowed bend radius for the bre optic cable is 15 mm during the instal-

lation and 10 mm during use. A smaller radius signicantly increases the attenuation

and may cause damage to the bre optic cable. Fibre optic cables must always be

handled carefully - especially during installation.

Cleaning optical connections:

If an optical connector (male) has been repeatedly inserted and unplugged or if failure

occurs, it may be necessary to clean the optical connector pins or sockets.

For cleaning purposes please use the optical cleaning set ORS 1 or the optical cleaning

tool ORW 1.

Input level optical transmitter OSC 100 micro

To ensure that the signals are transmitted through the bre optic cables, the RF signals

must meet the following requirements:

TV (DTT/CATV) DVB-T, Cable TV

To ensure that the digital television signals are transmitted and received, the digital signals

to the transmitter should be set to the same high level, especially when multiple digital

channels are transmitted.

As a guide, the input signals should meet the following requirements:

1. With QAM64, a maximum of 40 TV channels can be transmitted, with QAM256, a

maximum of 20 TV channels. With limitations on signal quality, up to 25 QAM256

TV channels can be transmitted. Wherever possible, a TV channel grid in the lower

frequency range should be preferred.

2. Total input power: -19 dBm (90 dBμV)

3. Depending on the number of digital TV channels, the following levels must be met at

the optical transmitter’s (OSC 100 micro) TV input:

All levels are stated per digital TV channel

• 40 TV channels with a maximum of 74 dBμV

• 20 TV channels with a maximum of 77 dBμV

• 16 TV channels with a maximum of 78 dBμV

• 10 TV channels with a maximum of 80 dBμV

• 8 TV channels with a maximum of 81 dBμV

The minimum input level (per digital channel) should be at least 74 dBμV.

If the quality of the TV input signal is not optimal or when the digital TV channels cannot

be equally levelled, the system should be adapted so that the optical attenuation of less

than 21 dB is reached to ensure correct signal reception at the outlet (especially when

many digital channels are transmitted).

10 / 16

FM and DAB+

FM and DAB+ signal level should be at least 10 dB lower than the digital TV signals.

SAT

1. Input level:

At OSC 100 micro there must be a level of 69 and 86 dBμV per transponder, so that

the AGC functions properly.

2. Differing levels within a satellite level:

The level difference of a satellite transponder level (VL/VH/HL/HH) should not exceed 4

dB. If the transponders have a gain slope on the inputs of the OSC 100 micro and the

level is high enough, you can, in certain circumstances, use the passive equalizer ERZ

60 to adjust the level (use one ERZ 60 for each satellite polarisation). If a long coaxial

cable is used between the LNB and the OSC 100 micro, you can adjust the level and

the gain slope (for each satellite polarisation) with the VWS 2500. If several transmit-

ters (OSC 100 micro) are cascaded, a VWS 2500 satellite distribution amplier must be

connected between the third and the fourth OSC 100 micro and also between the fth

and sixth in the cascade.

The maximum quantity is seven in the OSC 100 micro cascade. All unused F-type

connectors must be terminated with EMK 03, with the exception of the 4 SAT-inputs

of the OSC 100 micro, which due to DC voltage must be terminated with EMK 05. All

unused optical connectors of the optical network must also be terminated with the

OTC 1.

Input level optical receivers OEC 40 micro/OEC 44 micro

To ensure reception using the OEC 40 micro or OEC 44 micro receiver, the optimal level

must lie between -14 dBm and -8 dBm. Therefore the attenuation of the distribution sys-

tem should lie between 15-21 dB.

Output level optical receiver OEC 40 micro/OEC 44 micro

Please note that 1 dB of attenuation in the optical transmission path corre-

sponds to 2 dB less signal level in the electrical path (RF).

The output level of the optical receiver OEC 40 micro and OEC 44 micro is dependent on

the number of signals transmitted through the optical bre and the optical attenuation of

the section. The following are reference values for the signals at the receiver:

TV (DTT/CATV) DVB-T, Cable TV

The total output power of the OEC 40 micro is -27 dBm (82 dBμV) and -32 dBm (77 dBμV)

for the OEC 44 micro with 21 dB of optical attenuation. That means, that the fewer the

digital television channels transmitted, the higher the output level (per digital channel) and

the quality.
