 IF jumper: connection between IDU and other IF cable

 1/2 inch and RG-8U cable: connection between ODU and IF
jumper
 RG-8U cable is used for the distance less than 180 meter

 1/2 inch cable is used for the distance between 180m and
300m

IF jumper IF cable


 The IF cable provides -48V power for ODU and transmits the IF signal and ODU
management signal between IDU and ODU.
 IF jumper is one type of soft cable which help the chassis to be installed in the
300mm cabinet.



ODU
 Outdoor unit (ODU) realizes
the mutual conversion
between IF analog signal and
RF signal
 There are 3 types of ODUs
depends on the capacity and
transmitting power.


 The ODU is round and installed behind the antenna. It enables the conversion
between the IF analog signal and radio frequency (RF) signal, and amplifying the RF
signal. The ODU is irrelevant to the microwave transmission capacity. An ODU of the
OptiX RTN 910/950 can support the transmission capacity from 4xE1 to 1xSTM-1 in
SDH/PDH microwave system, and from 10Mbps(Max. E1 is 5) to 363Mbps(Max E1 is
75) in hybrid microwave system. When one ODU is configured for an antenna, install
the ODU behind the antenna directly or separately connected to the antenna
through a flexible waveguide . If two ODUs are configured for an antenna, the two
ODUs are connected to the antenna through a hybrid coupler.

 The OptiX RTN 950 support standard power ODU and high power ODU.



Hybrid Coupler
 When two ODUs share one antenna, the ODUs must be
connected to an RF signal coupler/ splitter (hybrid
coupler). Then, the hybrid coupler is connected to the
antenna.


 When two ODUs share one antenna, the ODUs must be connected to a hybrid
coupler whose full name is RF signal coupler/splitter. The hybrid coupler is a part of
an irregular shape with three interfaces. Two of them are ODU interfaces and one is
the antenna interface. The main function of the hybrid coupler is to couple and split
the RF signal.



Antenna
 The antenna implements the directional transmission and
reception of RF signals. The main parameters are frequency
band, diameter and antenna gain


 There are two methods of mounting the ODU and the antenna: direct mounting and
separate mounting. The direct mounting method is normally adopted when a small-
diameter and single-polarized antenna is used. In this situation, if one ODU is
configured for one antenna, the ODU is directly mounted at the back of the antenna.
If two ODUs are configured for one antenna, an RF signal combiner/splitter
(hereinafter referred to as a hybrid coupler) must be mounted to connect the ODUs
to the antenna.
 The separate mounting method is adopted when a double-polarized antenna or big-
diameter and single-polarized antenna is used. In this situation, a hybrid coupler can
be mounted. That is, two ODUs share one feed boom.

 Adaptive modulation (AM) is a technology wherein the modulation mode can be adjusted
automatically according to the channel quality.
 In the case of the same channel spacing, the microwave service bandwidth varies according
to the modulation mode. The higher the modulation efficiency, the higher the bandwidth of
the transmitted services. When the channel quality is favorable (such as on days when the
weather is favorable), the equipment adopts a higher modulation mode to try to transmit
more user services. In this manner, the transmission efficiency and the spectrum utilization
of the system are improved. When the channel quality is degraded (such as on days when
the weather is stormy and foggy), the equipment adopts a lower modulation mode to
transmit only the services with a higher priority within the available bandwidth and to
discard the services with a lower priority. In this manner, the anti-interference capability of a
link is improved and the link availability of the services with a higher priority is ensured.
 When the hybrid microwave equipment adopts the AM technology, it controls service
transmission based on the service bandwidth and QoS policy corresponding to the current
modulation mode. The E1 services have the highest priority. By adopting the CoS technology,
the equipment schedules Ethernet services of different types to the queues with different
priorities. The services in the queues of different priorities are transmitted to the microwave
port. When the queues of certain priorities are congested because of insufficient microwave
bandwidth, the queues of these priorities discard certain or all services. When the hybrid
microwave works in the lowest modulation mode, the equipment transmits only the E1
services and the Ethernet services of the high priority on the available bandwidth. When the
Hybrid microwave works in any other modulation mode, all the additional bandwidth is used
to transmit the Ethernet services. In this manner, the availability of the links that carry the
E1 services and the Ethernet services of the high priority is ensured and the Ethernet service
capacity is increased, thus providing the dynamic bandwidth.
 Slide shows the service change caused by the AM. The orange part indicates the E1 services.
The blue part indicates the Ethernet services. The closer to the edge of the blue part, the
lower the priority of the Ethernet service. Under all channel conditions, the E1 services
occupy the specific bandwidth that is permanently available. Thus, the availability of the E1
services is ensured. The bandwidth for the Ethernet services varies according to the channel
conditions. When the channel is in bad conditions, the Ethernet services of the low priority
are discarded.


Equipment Characteristics (Cont.)
 The features of AM technology
 The AM technology can use the QPSK, 16QAM, 32QAM, 64QAM,
128QAM, and 256QAM modulation mode
 The lowest modulation mode (also called "reference mode") and
the highest modulation mode (also called "nominal mode") actually
used by the AM can be configured
 When the modulation modes of AM are switched, the transmit
frequency, receive frequency, and channel spacing do not change
 When the modulation modes of AM are switched, the step by step
switching mode must be adopted
 When the AM switches the modulation modes to a lower one, the
services of the low priority are discarded but no bit errors or slips
occur in the services of the high priority

 If the radio link form is the Hybrid microwave, the maximum capacity of each channel of
microwave is 363 Mbit/s when the high power ODU is used or 183 Mbit/s when the standard
power ODU is used. If the XPIC technology is used, the service capacity of the microwave
channel can be doubled with same the spectrum bandwidth.
