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 fibre optic cable.

The RF signal fed into the OSC 100 micro is converted into an optical signal. This optical signal is fed through the fibre optic cable to an optical network (tap/splitter/attenuator) and thus finds 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 transmitters 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 fixed 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 fibre-optic infrastructure.

Suitable splitters (OVC xxx) and taps (OAC xxxx) are available for distribution of the optical output signal.

Notes on planning the fibre optic system

When designing a fibre 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 fulfils 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 optical 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 amplifier must be connected between the third and the fourth OSC 100 micro and also between the fifth and sixth in the cascade. The maximum quantity is seven in the OSC 100 micro cascade.

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 optical 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 fitted with an optical CLIK! connector. The taps and splitters 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 distribution network cannot be guaranteed.

CLIK! Patch cable

Coiled white fiber or optical cable with two connectors, no visible text or symbols

CLIK! Optical fibre connector ODC 2

When dealing with optical waveguides:

Installation and disconnection of the fibre 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 fibre optic cable by pressing the latch lock and pulling the cable out.

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 fibre optic cable is 15 mm during the installation and 10 mm during use. A smaller radius significantly increases the attenuation and may cause damage to the fibre 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 fibre 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).

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 dB V 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 transmitters (OSC 100 micro) are cascaded, a VWS 2500 satellite distribution amplifier must be connected between the third and the fourth OSC 100 micro and also between the fifth 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 system 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 corresponds 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 fibre 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.

RF output level per digital TV channel
TV channels	Opt. input at the receiver -8 dBm Opt. input at the receiver -14 dBm
	OEC 44 micro	OEC 40 micro	OEC 44 micro	OEC 40 micro
40	73 dBμV	78 dBμV	61 dBμV	66 dBμV
16	77 dBμV	82 dBμV	65 dBμV	70 dBμV
8	80 dBμV	85 dBμV	68 dBμV	73 dBμV
4	83 dBμV	88 dBμV	71 dBμV	76 dBμV
1	89 dBμV	94 dBμV	77 dBμV	82 dBμV

Information about the output levels of the OEC 40 micro or OEC 44 micro TV signal: These levels are guidelines in an ideal scenario, assuming that all digital TV channels at the input are of the same level and no consideration has been taken of any possible frequency responses. In more specific individual cases the digital output level would need to be measured.

SAT

The typical SAT signal output level on the OEC 44 micro output is:

• If the sum of all transponders has a total optical level of -14 dBm at the receiver input, the result for each channel is 59 dBμV at the output of the receiver (at 21 dB of optical attenuation and if 120 transponders are used).
• If the sum of all transponders has a total optical level of -8 dBm at the receiver input, the result for each channel is 71 dBμV at the output of the receiver (at 15 dB of optical attenuation and if 120 transponders are used).

The typical SAT signal output level on the OEC 40 micro output is:

- Transponders with an optical level of -14 dBm at the receiver input have a level of 67 dBμV at the output of the receiver (at 21 dB of optical attenuation and if 120 transponders are used).

- Transponders with an optical level of -8 dBm at the receiver input have a level of 79 dBμV at the output of the receiver (at 15 dB of optical attenuation and if 120 transponders are used).

- These levels are guidelines in an ideal scenario, assuming that all TV channels at the input are of the same level and no consideration has been taken of any possible frequency responses. In more specific individual cases the output level would need to be measured.

FM and DAB+

The FM and DAB+ signal levels will be lowered by at least 10 dB in relation to the digital TV signal.

The signal level on the sockets must have the desired values as per EN 60728-1 standard (stereo FM: 50-70 dBμV, DVB-T: 45-74 dBμV, SAT: 47-77 dBμV, digital cable TV: 47-77 dBμV, DAB+: 28-94 dBμV (Band III)). In certain cases, the RF output signal from the receiver or, if possible, the optical input signal must be attenuated by the passive components, such as an optical attenuator.

Application example

• The antennas, parabolic reflectors and multi-band amplifiers shown here are all typical examples.
• The selection of the right reception antenna (terrestrial and SAT) will depend on the location and size of the respective system.
• The RF output levels on the receivers are dependent on the number of signals transmitted over the optical fibre and on the optical input level on the receiver.
• The optical levels shown in the following examples were calculated using the typical attenuation values for passive components.

• We recommend using the CAS 90 as the minimum parabolic reflector size. In order to achieve optimum signal quality in larger systems, the CAS 120 should be used.
• All unused coaxial connectors must be terminated with EMK 03, with the exception of the 4 SAT inputs from OSC 100 micro, which due to DC voltage must be terminated with EMK 05. All unused optical connectors of the optical network must be terminated with the OTC 1.
• The integrated AGC of the OSC 100 micro optical transmitters ensures a constant optical output level independent of the number of digital terrestrial TV channels or the number of transmitted SAT transponders. The signal levels on the RF outputs of the OEC 40 micro/OEC 44 micro optical receivers are therefore dependent on the number of transmitted digital TV channels or SAT transponders.
• If an additional multi-switch is to be installed after the OEC 44 micro, a WFS 55 feed-in diplexer must be connected between the OEC 44 micro and the multi-switch.
