Product Description
 
Network Positioning
The RTN 380 can provide large-capacity backhaul microwave links or aggregation links on a mobile communications network or a private network, or substitute for optical fibers to transmit CPRI signals between baseband units (BBUs) and remote radio units (RRUs) in a distributed base station system to achieve longer transmission of RRUs.
As E-band full outdoor radio equipment, the RTN 380 has the following characteristics:
The RTN 380 operates at 71-76 GHz or 81-86 GHz frequency bands. It features large capacity, low inter-site interference, and rich frequency spectrum resources, as compared with radio equipment that operates at 6-42 GHz frequency bands. Therefore, RTN 380s can form a backhaul network for base stations densely deployed in a city and provide large-capacity backhaul links for aggregation sites. In addition, the RTN 380 can provide high-bandwidth microwave links for transmitting Ethernet services on a metro optical Ethernet in areas where optical fibers are difficult to lay out.
As compact full outdoor radio equipment, the RTN 380 integrates all functions in a chassis and does not need an extra installation site. Therefore, it allows carriers to construct and operate networks at lower costs than traditional split radio equipment.
On a mobile communications network, RTN 380s are mainly used to:
Support protection such as PLA and 1+1 HSB. Provide large-capacity backhaul microwave links for 3G/LTE base stations especially those that are densely deployed in urban areas. See Figure 1.
Provide large-capacity aggregation links for 3G/LTE base stations and implement multi-direction aggregation when working with OptiX RTN 900s. See Figure 2.
Provide microwave links between BBUs and RRUs in a distributed base station system to transmit CPRI signals to achieve longer transmission of RRUs. See Figure 3.
Work with the CSG to provide a microwave channel solution for transparent transmission on the IP RAN. See Figure 4.
Work with OptiX RTN 900 to implement the Super Dual Band solution through EPLA. This solution provides high-bandwidth, long-distance, and high-availability backhaul links. Super Dual Band Relay extends the E-band link transmission distance to three times the transmission distance of a single-hop E-band link. See Figure 5.

Specifications
RTN 380 specifications meet the high bandwidth requirements in E-Band microwave transmission. RTN 380 also has unique advantages in maintenance capabilities.
Table 1 lists the RTN 380 specifications.

Item Specifications
Microwave types IP microwave over native Ethernet and over PWE3 Ethernet
Microwave carrying common public radio interface (CPRI) services
Frequency bands 71-76 GHz and 81-86 GHz
Channel spacing 62.5 MHz, 125 MHz, 250 MHz, 500 MHz, and 750 MHz
Modulation schemes QPSK Strong, QPSK, 16QAM Strong, 16QAM, 32QAM, and 64QAM
NOTE:
In the co-channel dual polarization (CCDP) configuration, RTN 380 supports the highest modulation 16QAM.
NOTE:
The difference between strong modulation schemes and standard modulation schemes lies in encoding parameters. Strong modulation schemes have stronger FEC capabilities improving receiver sensitivity, but decreased air interface bandwidth.
Capacity Maximum air capacity: 2.5 Gbit/s
Maximum air-interface service throughput: 4 Gbit/s
Maximum switching capacity: 8 Gbit/s
RF configuration modes 1+0 mode
2+0 mode

NOTE:
In 1+1 or 2+0 mode, two OptiX RTN 380s are required for each site.
When transparently transmitting CPRI services, RTN 380s cannot be configured in 1+1 HSB mode.
