Product Overview
Product Introduction
Single-Port Long Reach Ethernet over Coaxial Extender is a type of converter
from RJ45 to BNC port, which supports long-range power supply transmission via
coaxial cable. It provides one BNC todXidl port dnd ur,e RJ45 μurt. The
product is equipped with two transmission modes which me 10011/lbs and 1 Mbps.
It can be modified according to the transmission distance.
Product Features
- Supports IEEE802.3 IEEE802.3u and IEEE802.3X standards.
- Supports IEEE802.3af and IEEE802.3at power supply standards.
- Port: 1*RJ45 10/lOOMbps, P-SNC.
- Supports RG59 coaxial cable: 400ml I OOMbps, I OOOmil OM bps.
- Supports MDI/MDIX self-adaption.
- Supports long-range power supply transmission via coaxial cable.
- Operating temperature: -30~65.
Typical Application
The product is divided into a transmitter (DH-LRl 002-1 ET) and receiver (DH- LRl 002-1 EC), which can be used together with EoC passive converter (LR I 002). The typical application is shown in Figure 1-1
