Connector (L Angle Type) (HIROSE made)
used for IDU IF IN/OUT
Step Procedure
Note: It is recommended that TNC (Male) L-angle connector for the
8D-FB IF cable is used to connect it to the IDU. When the N
(Male) straight connector is attached to the 5D-FB or 10D-FB
IF cable, use of the TNC (Male) - N (Female) (NJ-TNCP-LA)
L-angle adapter is needed.
1 Pass the tightening nut, the washer and the gasket on the cable in
the order shown in the figure.
Then, strip the cable jacket in the diameter shown in the figure.
[Applicable cable : 8D-FB-E]
Note: Be careful of insertion direction for the gasket and the tightening nut.
Note: Be careful not to damage the outer conductor.
Note: Do not reuse the gasket because the clamp deforms it after
tightening.
2 Insert the clamp to clamp the stripped cable jacket end. Open the
end of the outer conductor a little,
3 Insert the hood between the plastic tape with aluminium foil and
the outer conductor,

3. INITIAL LINE UP
This NLite E Section explains instructions for the initial lineup of the
equipment. Included is information on start-up, shut-down, IDU and ODU
equipment setting, antenna orientation and lineup test between two
stations.
When the NLite E Monitor is used for RX LEV monitoring, connect the
X0818 NLite E Monitor to the ODU. The NLite E Monitor operates on a
dry battery (6F22/9V).
Notes: 1. Insert the battery with correct polarity.
2. When the NLite E Monitor will not be used for extended
periods of time, remove the battery to avoid damage from
battery leakage and corrosion.
3. When the NLite E Monitor will be connected to the ODU,
control corresponding ODU to Antenna Alignment mode
using LCT in Maintenance ON.
ROI-S05750 INITIAL LINE UP
3-2
3.1 Start-up
The procedure for starting the equipment is shown in Chart 3-1.
Warning: 1. The –48 V DC is superimposed on the centre conductor
of the IF coaxial cable between the MODEM and the
ODU. Connecting test equipment directly to this
terminal may damage it and touching the coaxial cable
core may cause electrical shock.
2. Do not disconnect the IF cable between the MODEM and the
ODU in operating condition, to avoid damaging the NLite E ,
turn the IDU power OFF before connecting/disconnecting
the IF cable.
3. Do not allow open or short circuit of ODU TX output
with the TX power on conditions. Perform the TX Mute
control in the Maintenance mode or turn the PWR switch
off at the IDU before disconnecting cable or feeder from
the ODU TX output.
4. After turning ON the equipment, wait at least 1 minute before
turning it OFF again. Repeatedly turning the power ON and
OFF within a short interval may cause the NLit E to fail.
Caution: 1. In a system using the OPTICAL OC-3 INTFC, do not
stare at the laser beam or look at it directly with optical
instruments. Otherwise, it may hurt your eyes (Class 1
Laser Product).
2. Be careful top surface above MODEM of the IDU is hot in
operation.
3. When replacing the MODEM, OC-3 INTFC or DC-DC CONV
(optional) turn off the PWR switch and disconnect all cables
connected to the module which is to be replaced.
4. When dismounting the ( ) INTFC, turn off the PWR switch on
the MODEM and disconnect all cables connected to the ( )
INTFC.
5. In the SONET XPIC system, the system parameter setup must
be performed at the Master station first, then at the Sub Station.
6. In the SONET XPIC system, the Main Master and Sub
Master channels must be connected to one dual polarized
antenna.

Safety Guideline for Microwave Radiation Hazard
The Microwave and Millimeter-wave that NLite E series are transmitting is at a very small radiation
level and never has been reported to effect human health. Advanced countries concerned about health
hazards have started to regulate the radiation levels. The operator should not work near the parabolic
antenna during RF transmission. The area in front of and to the side of the antenna show high radiation
levels. Please see below figure and calculation sample 1.
The front side of antenna presents a high power density in the antenna beam area. Therefore, the user of
this system should pay attention not to radiate the beam against humans at any time. (Please refer below
calculation sample 2)

In addition, the Power density and Field strength level is calculated by equation below.

P+G−30

Where: P = Output power of ODU (dBm),
G = Antenna Gain (dBi),
(in consideration of the angle from antenna)
K = Reflection factor =2.56 (given),
R = Distance between Human and Antenna (m)
Calculation example 1, (90 degree side of antenna)
NLite E = 18 GHz/+23 dBm,
Antenna diameter = 0.6 m,
0 degree antenna gain = 39 dBi,
90 degrees side antenna gain = −24 dBi, (90 degrees attenuation = −63 dB),
Distance = 0.1 m
Power density S (mW/cm2) = 0.0016 ≤ 0.01
Calculation example 2, (0 degree, front side of antenna)
NLite E = 7 GHz/+27 dBm,
Antenna diameter = 1.8 m,
0 degree antenna gain = 40 dBi,
Distance = 100 m
Power density S (mW/cm2) = 0.01
