P-12


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.



P-13


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.

ChannelCapability

E1 Services

EthernetServices

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.



P-16


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

Weight:

< 260 mm X 260 mm X 92 mm (width X height X depth)Dimension:

By the types of the antenna interface on ODU, ODU can be classified into waveguide interface ODU and coaxial interface ODU. Usually 7GHz to 38GHz ODU is waveguide interface and 6GHz SP serial ODU is coaxial interface.

The waveguide interface ODU can be installed by direct mount.

The typical waveguide interface ODU is 260 mm long, 260 mm wide, and 92 mm high. Its weight is not more than 5 kg and its power consumption is not more than 40 W. The following introduces the ODU interfaces. At the bottom of the ODU, there is a round interface – antenna port. The OptiX RTN 910/950 equipments are installed through direct covering. Thus, through the antenna interface, the ODU is directly connected to the antenna back or the hybrid coupler. The ODU has the grounding double-screw bolt, RSSI test interface, and an IF interface. The RSSI test interface connects to the multi-meter for testing and receiving the signal intensity. The IF interface connects to the IF cable, exchanges the IF signal and ODU management signal at on the IDU IF board, and receives the DC feed current.

RSSI is the receive signal strength interface used for testing the ODU receiving power.

Hybrid coupler (Waveguide interface)

In the OptiX RTN 910/950, the hybrid coupler combines and splits the RF signals, that is, combines two ODU RF signals into one RF signal in the transmission direction, and sends the signal to the antenna. In the receiving direction, the hybrid coupler splits the RF signal received by the antenna into two RF signals, and then sends the signals to the ODU. As shown in this figure, the waveguide cavity of the hybrid coupler provides three ports: antenna port (also called common port), primary tributary port and secondary tributary port. The RF signals received by the primary tributary port and secondary tributary port are integrated into one RF signal at the waveguide cavity, and the signal is output from the antenna port. The RF signal received by the antenna port is split into two FR signals at the waveguide, and then the signals are output from the two tributary ports.

Ethernet Service Protection-ERPS

ERPS is applicable to ring physical networks and can provide protection for the E-LAN servicesbetween all the nodes on the ring network. Generally, when a ring network is configured withERPS, the main node blocks the ports on one side so that all the services are transmitted throughthe ports on the other side. In this manner, service loops are prevented. If a section of link failsor an NE becomes faulty, the main node unblocks its blocked port so that the services are switched from the faulty point to this port for transmission. In this manner, protection for theringnetwork is realized.

The Ethernet ring network shown in slide is configured with ERPS. Generally, the main node (NE D) blocks its port that is connected to NE A, and all the services are transmitted over the link NE A - NE B - NE C - NE D. When the link between NE A and NE B becomes faulty,NE D unblocks the blocked port so that the services can be transmitted over the link NE A - NED - NE C - NE B.



P-117


Ethernet Service Protection-MSTP

The OptiX RTN 910/950 supports only the MSTP protocol that uses the common and internal spanning tree (CIST). The MSTP that uses the CIST can be used as a rapid spanning tree protocol (RSTP). The RSTP is applicable in the case of a network loop. This protocol adopts certain algorithms to reconstruct a loop network into a loop-free tree network and thus prevents Ethernet frames from increasing and cycling in an endless manner on the loop network. In the case of the OptiX RTN 910/950, the MSTP is used to prevent a network loop on the access side.

When the user equipment accesses the OptiX RTN 950 through two different trails, you can configure the ports on the OptiX RTN 950 that are connected to the user network into a port group. This port group, together with the switch on the user network, can run the MSTP. Hence, if an service access link becomes faulty, the MSTP enables a re-configuration togenerate the spanning tree topology, thus providing protection for the user network that is configured with multiple access points.
