PRODUCT DESCRIPTION
Description
N3787 series is Peer-to-Peer fiber optic transmission system released by Infinova as per the
current market demands. By Ethernet transmission medium, it achieves switchover between
twisted paired electrical signals and remote optical signals. With the rapid development of
informatization construction, there is a growing demand for data, audio, image and other
multi-media communication. Ethernet broadband connection is thus becoming more and more
important. However, the traditional Category 5 cables can only achieve 100m transmission for
the electrical Ethernet signal, which no longer meets the actual need in transmission distance
and coverage scope. While fiber communication, with its large capacity, high security, light
weight, small size, no relay and long transmission distance, is widely used in WAN and other
large-scale network. It's applied for remote 1000M Ethernet data switch with large-capacity
Peer-to-Peer transmission
N3787 series single mode transmission system provides the ability to transmit 1000M
Ethernet data over one fiber in full duplex and point-to-point mode. The Ethernet signal on
two ends are 10/100/1000M self-adaptive. There are two or eight RJ45 Ethernet ports on the
transmitter and receiver, easy to connect with different Ethernet devices.

INSTALLATION
To install the apparatus, it is necessary to allow enough space to accommodate the bend radius
of the optical cable connected to it. The transmitter/receiver requires as short as practical
Category 5 or 6 UTP cables to transmit Ethernet data. The RJ45 connector is applied for the
Ethernet port.
POWER SUPPLY
The N3787 series is powered by a plug-in 24VAC@830mA power supply with 2-pin terminal
block connector.

Note:
When the series is powered together with other devices (cameras and etc.) by a single
24VAC power source, please make sure that the related device has a full-wave (bridge)
rectifier circuit.

CABLE DIAMETER CALCULATION AND LIGHTNING & SURGE PROTECTION
Relation between 24VAC Cable Diameter and Transmission Distance
In general, the maximum allowable voltage loss rate is 10% for AC-powered devices. The
table below shows the relationship between transmission power and maximum transmission
distance under a certain specified cable diameter, on condition that the 24VAC voltage loss
rate is below 10%. According to the table, if a device rated at 50W is installed 17-meter away
from the transformer, the minimum cable diameter shall be 0.8000mm. A lower diameter
value tends to cause voltage loss and even system instability.

Lightning & Surge Protection
The product adopts multi-level anti-lightning and anti-surge technology integrated with gas
discharge tube, power resistor and TVS tube. The powerful lightning and surge protection
barrier effectively avoids product damage caused by various pulse signals with power below
4kV, including instantaneous lightning, surge and static. However, for complicated outdoor
environment, refer to instruction below for lightning and surge protection:
The product features with dedicated earth wire, which must be firmly grounded. As for
surveillance sites beyond the effective protection scope, it’s necessary to erect independent
lightening rods to protect the security devices. It’s recommended to separate the lightning
rod from the mounting pole, placing the rod on an independent pole, as shown in the figure
below. If the product has to be installed on the same pole or pedestal for lightning rod, there
should be strict insulation between the video cable BNC terminal, power cable, control
cable and the standing pole of the lightning rod.
For suburb and rural areas, it’s recommended to adopt direct burial for the transmission
cables. Overhead wiring is prohibited, because it’s more likely to encounter lightning strike.
Use shielded cables or thread the cables through metal tubes for burial, thus to ensure the
electric connection to the metal tube. In case it’s difficult to thread the cable through the
tube all the way, it’s acceptable to use tube-threaded cables only at both ends of the
transmission line, yet the length in burial should be no less than 15 meters. The cable
sheath and the tube should be connected to the lightning -proof grounding device.
Additional high-power lightning-proof equipment and lightning rods should be installed for
strong thunderstorm or high induced voltage areas (such as high-voltage substation).
The lightning protection and grounding for outdoor devices and wires should be designed
in line with the actual protection requirement, national standards and industrial standards.
The system should perform equipotential grounding by streaming, shielding, clamping and
earthing. The grounding device must meet anti-interference and electric safety requirements.
There should be no short-circuiting or hybrid junction between the device and the strong
grid. Make sure there’s a reliable grounding system, with grounding resistance below 4Ω
(below 10Ωfor high soil resistivity regions). The cross-sectional area of the earthing
conductor should be no less than 25mm².
