Figure 1 iPASOLINK 400
The traffic interface of iPASOLINK 400 is a basic D/I interface module and four (4) front
access universal card slots which are connected to TDM cross connect and L2 switches with
interface buses. These card slots are provided for radio interface (modem) and additional
interface to satisfy various D/I or interface and topology requirements. Versatility of the
iPASOLINK 400 is thus obtained. As the basic D/I interface configuration, iPASOLINK 400
can be configured up to four 1+0, two 1+1 twin path, hot standby, diversity radio links or,
thanks to NEC’s most advanced cross polarization interference canceling techniques, double
the transmission capacity up to 880 Mbps utilizing both polarizations within the same costly
and limited licensed radio frequency channel. All this is achieved without any header

ty up to 880 Mbps in 56 MHz (55 MHz for
18 GHz band) bandwidth by adopting NEC’s state-of-the-art XPIC technology. The additional
required components from single pole transmission are; dual-polarized antenna, one more
ODU, associated cable kit, and firmware upgrade in IDU. Through these additions, you can
achieve double capacity without additional footprint or indoor mounting space.

NEC has developed 10 dB Coupler over the full range of microwave frequencies for
iPASOLINK Series digital microwave radio point-to-point fixed wireless systems. This 10 dB
Coupler comprises directional coupler, antenna interface, radio mounting interfaces and
polarizer. 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 10 - 38 GHz Bands. NEC 10 dB Coupler
is suited for Andrew or RFS Antenna, and all NEC ODUs.

NEC has developed Ortho-Mode Transducer (OMT) over the full range of microwave
PASOLINK Series digital microwave radio
point-to-point fixed wireless systems. The OMT comprises Ortho-Mode transducer, antenna
interface and radio mounting interfaces. The two independent RF signals received by dual
polarized antenna are separated and sent to two outdoor units (ODUs) through the OMT for
OMT enables dual polarization feature to double
the transmission capacity for the PASOLINK
system. NEC OMT has WG connection type for
11-38 GHz Bands, which is suited for RFS
Antenna and all NEC ODUs.
