Green cabling efforts enhanced with proper media converters

More and more businesses are investing in green cabling for variety reasons. LEED approval, improving reputation and other reasons are all at the top of the list, and companies often forsake other improvements in order to go green. However, as the criteria for LEED certification and what it means to go green in general evolve, companies have considerable factors to keep in mind.

Approval regulations

According to Cabling Instalation & Maintenance, the United States Green Building Council recently approved the LEED v4 rating system, and upgrade of the previous certification process. While applications filed under the previous version will be accepted until June 2015, the USGBC is migrating to v4 as quickly as possible.”There are 46 countries and territories around the world and all 50 U.S states represented in the voting pool for LEED v4,” LEED Steering Committee chair Joel Ann Todd said. “The rating system must earn a significant percentage of the overall vote as well as a majority approval from each of the various LEED stakeholder groups. This ensures that rating system approval represents the full diversity of USGBC’s membership.”


Many firms are starting to upgrade not only their heating, electrical and building materials to meet green standards, but network infrastructure and audio/visual communications technology as well. This means higher demand for high quality media converters and cabling solutions such as fiber optics.

Sustainability remains a concern through any business investment, and firms are ensuring that they embrace these practice as regulations become standardized for this technology as well.

Technology infrastructure

The key to embracing green initiatives and making sustainability a sustainable effort itself is having thte right technology in place that streamlines these efforts. High-quality Ethernet to fiber optic converter and related tools that help optimize networks and eliminate latency will be essential for success.

Fiber optics in particular is a popular solution for green infrastructure because it helps lower costs through reduced energy consumption and providing support for future changes as well.

“The high bandwidth and long link lengths supported by fiber networks enable LAN architectures that minimize the use of electronics – saving energy, reducing the materials needed, and creating a network with the bandwidth to support future applications,” the TIA Fiber Optic Technology Consortium noted, according to the source.

Ultimately, green efforts should start including fiber optic converters and cabling to ensure sustainability and help further efforts so that they are compliant with not only current standards, but future ones as well.

Introduce of Ethernet to Fiber Optic Converters

Ethernet Media Converter is a device to convert and transmit Ethernet networks into Ethernet fiber optic networks. It can convert digital electric Ethernet signals to optical signals. Ethernet to fiber optic converter enable connections of UTP copper-based ethernet equipment over a fiber optic link to take advantage of the benefits of fiber which include:

a. Extending links over greater distances using fiber optic cable

b. protecting datafrom noise and interference

c. Future proofing your network with additional bandwidth capacity

Copper-based Ethernet connections are limited to a data transmission distance of only 100 meters when using unshielded twisted pair (UTP) cable. By using an ethernet to fiber conversion solution, fiber optic cabling can now be used to extend this link over a greater distance.

An Ethernet to fiber media converter can also be used where there is high level of electromagnetic interference or EMI which is a common phenomenon found in industrial plants. This interference can cause corruption of data over copper-based ethernet links. Data transmitted over fiber optic cable however is completely immune to this type of noise. An Ethernet to fiber optic converter therefore enables you to inter-connect your copper-ethernet devices over fiber ensuring optimal data transmission across the plant floor. By utilizing ethernet to fiber media converters, the benefits of fiber optic cabling can now be realized for copper-based ethernet infrastructures.

The advantages of Ethernet to Fiber Optic Converters

1. Protects your investment in existing copper ethernet-based hardware

2. Provides you with the flexibility to add fiber on a port-by-port basis

3. Enjoy the benefits of fiber without have to make wholesale changes

4. Fast ethernet or Gigabit ethernet to multi-mode or single mode

5. Ethernet to fiber and fiber back to ethernet links

6. Create copper-fiber connections with fiber switches

Media Converters for Ethernet fiber converter transforms the signal from a UTP/RJ45 ethernet link to one that can be used by a fiber transceiver. Media converters can connect to various optical fiber cable such as multimode, single mode or single strand fiber cable. Options exist for many distances to suit the needs of a particular ethernet to fiber application. And, fiber interface connectors can be dual ST, dual SC, dual LC or single SC type.

Ethernet to fiber media converter models that are best suited for enterprise and Service provider applications, offer an on-board processor that continuously monitors that both the copper and fiber connections are up. This functionality, generally referred to as “Link Pass-Through”, monitors the state of the link to the end devices and to ensure that each end-point knows whether the entire link is up or not. Some media converter products do not have this intelligence and simply “nail up” the link even though the remote copper device may be down or the fiber link broken. With Link Passthrough functionality available in all Perle Ethernet to Fiber Optic Converters, the network’s SNMP management system can be alerted when a fault occurs so that corrective action can take place.

The most common type of Ethernet Fiber Converter is one that is a standalone device (managed or unmanaged) with its own power adapter. They convert fixed speed Fast Ethernet, Gigabit or rate converting 10/100/1000 UTP links to 100Base-FX or 1000Base-X fiber connections. Where a large density of media converters are required, chassis-based systems are also available. These rack mountable units can house up to 19 managed or unmanaged media converter modules providing redundant power for AC and 48v DC environments.

FiberStore supply many types of Ethernet Media Converter, such as 10/100M BIDI WDM Ethernet media converter, 10/100M Ethernet media converter with SFP port or SC port. These media converters extend transmission distances well beyond the capabilities of twisted pair wiring, and can reach up to 2km, 20km, 40km, 60km, 80km, 100km, or 120km.

What is the Relationship Between Media Converter and Network Switch

Fiber optic media converter is a very simple networking device that connects two different types of media, and was introduced to computer networks nearly two decades ago. Fiber media converters are used to convert electrical signal to light signal and vice versa. They are basically used as network extenders to extend the distance from several hundreds of feet to several thousands meters. They are perfect for linking networks between campus buildings.

This converter plays an important part of fiber types of cabling system in connection with each other, based on the copper wiring system. It supports different communication protocols, such as gigabit Ethernet, fast Ethernet, Ethernet media converter, etc. It also supports multiple cabling system like coax, twisted pair, multi and single-mode fiber optic. On the other hand, a network switch is a device to connect computer network and equipment. This is a multiport network operating systems, processes and routes data for various networks such as fiber channel, Ethernet, etc. A single swithc operation in one or more layers of the OSI switch, however, operating in more than one layer is known as a multiple layers switch for a time.

What is the relationship between a media converter and a network swithc?

The interrelationship between a media converter and a network switch today is that both can act and perform the same functions. Both operate within the Open Systems Interconnection (OSI) model which is hierarchical and structured in the form of layers such as layer 1, layer 2, layer 3 and so on.

Layer 1. Only the media converter work role transformation on the layer 1 and the electrical signals and the media do not have any data changes. These converters have two outlets, which are “in”, and “out” and through these channels electrical signals are transmitted across. For examole thick coax to Thin, UTP to fiber etc.

Layer 2. The process of linking data takes place at this layer and both switches and converters operate together and perform the function of differentiating network addresses. In this layer media converters have 2 or 3 ports whereas a network switch has 4 or more ports.

Layer 3. Network in this layer and switches using the IP address to identify the location of the various network. Position reference address in computer memory, LAN workstation and so on. Switch is in this layer is faster and smarter, in the layer 2 switch and identification network location but not only a physical device.

Different types of fiber media converter range from PC card converter and small independent equipment system, there are a lot of extra high density advanced features. Media converter provides a transitional course from copper to fiber, so can reduce the electromagnetic interference. On the other hand, the different types of switches are unmanaged, management, intelligent network switches and enterprise management.

What Are Optical Multiplexers?

An optical multiplexer, basically, a device, an input can be routed to the many different output, usually is 16. It utilizes fibr optic technology, is usually controlled by use of software and a totator block, and has an optical path that is actually coupled through several COL-UV/VIS collimating lenses. So, this is basically what a fiber optic multiplexer is…but what exactly do these devices do, and what are they used for? Well, that is a good question, and here is some information that might help you. Although it is hard to tell you all about optical multiplexer in an article, here are some things that may help you better understand the complex operation of equipment.

1 Channel Video to Fiber SM FC 20km Optical Video Multiplexer

Basically, optical multiplexer using one side of a fiber optic cable, so a lot of things can send information in the same line. It is like a giant multiple input connector that allow several signal input, and then send a fiber optic cable. This information travels along this wire until, it comes into contact with a demultiplexer, which is like another attachment at the end of the cable that again splits up the signals and sends them on their way.

One of the most obvious uses for a optical multiplexer is the fact that it saves a lot money. Therefore, by placing one end of the multiplexer, a signal separator in another company can save a lot of money in the fiber optic cable.

To some extent, the resulting network information, and the way to travel, can be compared to a large highway. This large highway connections may be two very big city, in the morning, there may be a lot of traffic on a highway to go to other city. However, although all use the same highway, traffic is it does not actually come from the same place, also is not all in the same place.

On the highway traffic slowly from a different side of the road in a city, it will exit in the same way when it arrives at destination. In this way, the illustration is a lot like a fiber multiplexer/demultiplexer system, with the cars being the information, the cities being the multiplexers, and the freeway being the fiber optic cable.

This is a very basic method to describe the optical multiplexer how to work, and i hope it can help you to understand. It is not a too hard to master the concept of, even if the fiber is still a technology, can make people don’t use it all the time. The best way to learn about fiber optic cable is to either research it, or to actually work with it in a network or a system. A lot of different industries now make use of the speed with which fiber optic can deliver information. Light travels a lot faster than electric signals, after all. Optical Multiplexer is popularly with telecommunication operator and suitable in business for communication operator, government and kinds of entities. It is one of the most transmission equipment in point-point fiber optic network. Typical optical multiplexers are Video & Data & Audio Multiplexers, PDH Multiplexer.
