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.
