This warranty does not extend to any Infinova products which have been subject to acts of accident, misuse, abuse, neglect, improper application or installation, improper operation or maintenance, connection to an improper voltage supply or to materials which have been altered or repaired outside an authorized Infinova factory repair center.
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.
MAIN FEATURES Storage and forward mode to match devices at different speeds Non-blocking wire-speed reception and transmission, transmission without head-of-line blocking Support feedback and diagnosis functions Detection and correction of port polarity at the physical layer ...
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.

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%.

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.
