System Overview
NEC has developed the PASOLINK NEO, a narrow band point-to-point digital microwave
relay system operating at radio frequency (RF) bands of
6/7/8/11/13/15/18/23/26/28/32/38/52 GHz.
GHz

The PASOLINK NEO system provides interface types of PDH, SDH and LAN. The
transmission signals are 5 to 48 x E1, 1 to 2 x E3, 1 to 2 x STM-1, 2/4 x 10/100 Base-T(X)
and GbE signals.

The systems consist of antennas, outdoor unit (ODU) and Indoor unit (IDU) same as PASOLINK series.
They are connected through a coaxial cable for each radio channel. Available configurations are non
protected type (1+0) and protected type (1+1). The protected type is available for twin-path type and
hot-standby type.

System Composition
• 1- Indoor unit (IDU) ( Modulation-Demodulation unit)
• 2- Outdoor unit (ODU) ( Transmit – Receive unit)
• 3- IF cable and connectors ( To connect the IDU & ODU)
• 4- Antenna on the required microwave band
• 5- Hybrid ( coupler ) in case of 1+1 one antenna configuration
• 6- RF cable ( If the ODU is not direct mounted to the antenna)

Switchover Control
• Switchover Modes:

1. Automatic Switchover:
Switching is automatically initiated if any failure or abnormality was detected in
the online section.

2. Manual Switchover:
The operator initiate this switchover by LCT or PNMT for the maintenance and
test purposes. The manual switching has two selection Manual or Forced
switchover.

• Switching Priority:
The switching priority is only applied under automatic switching control.

Outdoor Unit ( ODU )

• The transmitter-receiver is designed to handle an 8-155 Mbps digital signal in the 6-52 GHz
bands. The equipment is designed to withstand severe weather conditions. To achieve high
system gain performance, quadrature phase-shift keying (QPSK) modulation is applied. And to
achieve high frequency efficiency performance, 16/32/128-quadrature amplitude modulation
(16/32/128QAM) is applied. This ODU can apply to each modulation.

• Advanced integrated circuit technology, e.g., MMIC and MIC, is applied to the entire RF circuit in
ODU.

Hybrid Combiner
NEC has developed Hybrid Combiner/Divider over the full range of microwave frequencies for PASOLINK Series digital microwave
radio point-to-point fixed wireless systems. This Hybrid Combiner/Divider comprises directional coupler, antenna interface, radio
point- to- comprises
mounting interfaces and polarizers. The RF signal power received by the single polarized antenna is equally distributed and sent to
polarizers. is
two outdoor units through the Hybrid Combiner/Divider for 1+1 protected systems.
protected
There are two types of NEC Hybrid Combiner/Divider, one is coaxial cable connection type for 6/7/8 GHz Bands and the other is
coaxial
WG connection type for 11 – 52 GHz Bands. NEC Hybrid Combiner/Divider is suited for Andrew or RFS Antenna, and all NEC
ODUs.

6/7/8 GHz Coupler (N-type) 11 ~ 38 GHz Coupler (N-type)

10 Coupler
The RF signal power received by the single polarized antenna is unequally distributed to two outdoor units in
the ratio of 9 to 1 through the 10 dB Coupler for 1+1 protected systems. Using this 10 dB Coupler, regular
side signal level could be kept higher than in using 3 dB equal Combiner/Divider.
There are two types of NEC 10 dB Coupler; one is coaxial cable connection type for 6/7/8 GHz bands and the
other is WG connection type for 11 - 38 GHz Bands. NEC 10 dB Coupler is suited for Andrew or RFS
Antenna, and all NEC ODUs.

Ortho – Mode Transducer ( OMT )
OMT enables dual polarization feature to double the transmission capacity for the PASOLINK
system. NEC OMT has Wave Guide connection type for 11-38 GHz Bands, which is suited for
RFS Antenna and all NEC ODUs.

The OMT comprises Ortho-Mode transducer, antenna interface
and radio mounting interfaces.

ODU Mounting Configurations
Suitable configuration can be selected from various ODU mounting styles:
• Direct Mounting on Antenna
• Separate Mounting with Antenna using Waveguide or Coaxial Cable
• 1+1 system with Hybrid Combiner / Divider
• 2+0 system with Dual Polarization Antenna
