It allows the system to extend IP cameras beyond cable distance limitations and also acts as a PoE inserter. Nufiber NF-9801-PSE/PD Ethernet over Coax Extender allows IP cameras to transmit over Coax cabling. As shown in the following picture, the Ethernet extenders are deployed to connect the main office to Manufacturing Plant A, B, C respectively by converting Ethernet to UTP, so as to extend transmission distances.įigure 3: Application of Ethernet Extender.Product Description 10/100M 1 BNC port 1 RJ45 port POC Ethernet over Coaxial Converter with POE 300M Description Extenders will work with all sorts of copper wire already in place, significantly cutting down the labor and cabling involved in a network installation. If there is an existing twisted-pair copper or telephone wire running, then using a pair of Ethernet extenders can be the best fit. There are also cases when you have to use original facilities to extend your LAN. Each end device, such as a workstation, is also linked to the media converter for converting UTP signal to optical signal, which is then sent back to the computer room.įigure 2: Application of Media Converter. The Ethernet switch is connected to the media converters on the chassis via copper cable. The figure below illustrates a typical application case of fiber optic media converter - it is used to connect telecommunication room switch to workstations located beyond 100m in a large facility. Media converters are commonly used in all sorts of industries and sectors to provide a connection between fiber and copper, such as enterprises, campus and Metro Ethernet. When to Use Media Converter or Ethernet Extender? While extender usually supports Ethernet speeds of 10/100/1000Mbps, allowing 10/100Base-TX Ethernet data with SHDSL technology to be transmitted up to 20 km or extending 10/100/1000Base-T Ethernet up to 3 km using VDSL technology. Thus, media converters can support 10/100/1000Mbps or even 10Gbps, reaching longer transmission distance up to 160 km. And their transmission efficiency largely depends on the physical media used. While Ethernet extender converts Ethernet to DSL and reverts signals back to electrical format across coax cabling, T1/E1 and copper cabling. In fiber-to-fiber connections, media converters bridge multimode to single-mode fiber, dual fiber to single fiber or achieve wavelength conversion. In copper-to-fiber connections, a pair of media converters are used to convert electrical signals to optical ones and vice versa. Media converter usually performs the function of photoelectric conversion. Media Converter vs Ethernet Extender Performances But distinct differences can also be found between media converter and Ethernet extender.
With compact size and independent power supply, media converter and Ethernet extenders can be both flexibly installed for LAN extension. Media Converter vs Ethernet Extender: Which to Choose? It eliminates the need for installing a new cable infrastructure, saving costs and time.įigure 1: Media Converter vs Ethernet Extender. While Ethernet extender converts Ethernet to DSL (Digital Simulation Language) and reverts signals back to Ethernet, which helps extend 10/100/1000 Ethernet connection using coaxial cabling, copper wiring or single twisted pair such as Cat 5e/6/7 that primarily deployed in alarm circuits, T1/E1 circuits, RS-232, RS-422, RS-485, CCTV (Closed Circuit Television) and CATV (Community Antenna Television) applications. Fiber media converter adds fiber cabling to the legacy copper cabling system, therefore extending the service life of original facilities and bringing new technologies and applications available for network upgrades. Media converter is a cost-effective device mainly used for copper-to-fiber conversion or fiber-to-fiber connections for extending transmission distances and improving transmission quality.
