Network Extension and Media Conversion

Network Extension and Secure Management

Governments and municipalities are looking to get the most return out of their infrastructure investment. They can do this through fiber integration, and extension. For network extension within a building, between buildings, or throughout a campus, Transition Networks can help integrate fiber with copper equipment or overcome the distance and security limitations of copper or UTP cable.

The ION Platform offers cost-effective solutions for integrating, optimizing and navigating networks. The system accommodates a variety of modules and interface devices supporting multiple protocols and networking environments, providing simple and secure management of all the connected network interfaces. The ION Platform optimizes installed multimode fiber within buildings, capitalizes on the distance advantages of single mode fiber between buildings, and optimizes the installed fiber infrastructure with bi-directional single strand fiber. It allows various components to be easily configured, monitored and managed remotely while providing a high level of secure access to management data.

Secure Connection of IP Phones and Desktop Workstations over Fiber

Like many other organizations with limited budgets, government agencies typically need to make the most of their investment in their existing copper infrastructure. Transitioning from copper to fiber can be challenging, and many government agencies can’t afford any interruption of critical services. The benefits of fiber optic cabling are widely recognized: fiber optic cable is more secure and protects data from noise and interference, offers greater bandwidth and capacity, and is able to extend networks over a greater distance.

Transition Networks provides a diverse portfolio of solutions to cost-effectively integrate fiber into any network. Media conversion solutions are a quick, inexpensive method for delivering Ethernet over fiber, TDM over fiber, and providing a demarcation device for Ethernet services. MSA compliant optical solutions, such as small form factor pluggable transceivers (SFP, SFP+, and XFPs) and optical multiplexing solutions, offer the ultimate flexibility for connecting, growing, and modifying networks while ensuring interoperability with other MSA compliant devices. Switching and Ethernet extension solutions, including managed, unmanaged, and hardened switches for commercial or harsh environments, help deliver services wherever needed.

Fiber-to-the-Desk (FTTD) allows for greater transmission distances and speed, supports services requiring increased bandwidth, and enables IP phones. Municipal and military agencies are also deploying FTTD to reduce the risk of security breaches while providing these services, since it is virtually impossible to tap into fiber cabling without being detected by network managers. Transition Networks offers multiple options for quickly and easily delivering Ethernet service via FTTD.

  • Fiber Network Interface Cards (NICs) allow for simple integration of fiber at the desktop or laptop. PCIe and M.2 network interface cards are available in speeds ranging from 100Base to 10 Gigabit. Many NICs support Wake-on-LAN (WoL) power management and are easily installed with included software drivers for multiple operating systems.
  • Scorpion-USB™ Ethernet Fiber Adapters create a secure data connection over fiber between a USB port on a PC, laptop, or tablet. No external power supply is needed, and the advanced power saving mode preserves PC battery life. Installing Scorpion-USB™ is as simple as plugging the adapter into the USB port and installing the desired driver.
  • PoE Media Converters and PoE NICs allow network managers to use fiber to connect IP phones and desktops over the same backbone. The Power Sourcing Equipment Link Pass Through (PSE LPT) feature increases reliability by automatically rebooting IP phones if there
    is a loss of link. Power consumption can be reduced utilizing features such as Wake-on-LAN (WoL). Stand-alone media converters save space as their compact design allows them to be discreetly tucked behind the PC or desktop.

Unidirectional Network Security

While most networks rely on full-duplex, simultaneous bidirectional communications to provide maximum bandwidth and throughput, there are some situations where bidirectional communications are not required. For example, if a computer’s primary function is to receive data and compile it into a database, then its ability to transmit data can be disabled, providing additional data security. Unidirectional communication is often used to safeguard information in secure environments such as in government agency and military networks. A unidirectional network device, sometimes referred to as a unidirectional security gateway or a data diode, provides a connection between two or more networks with different security classifications and helps to protect assets by ensuring, on a physical layer, that information is directed only to, or from, the appropriate network as designated by the directional device.

Combining unidirectional communications with media converters can add two levels of physical security to your network. First, media converters allow you to take advantage of the inherent security offered by fiber optic cabling while connecting copper based equipment to a fiber network. Second, adding unidirectional technology creates a physically secure one-way communication channel between a secure network and an unsecure network.

The first diagram illustrates how unidirectional copper-to-fiber media converters can be deployed to ensure a secure data environment. These devices allow data from a classified, high-security area to be transmitted to a low-security area, while preventing unsecure data from re-entering the classified network.


  • Protect assets and data
  • Block access to the secure area
  • Prevent manipulation of secure data

The second diagram illustrates a secure network that needs to be updated with data from an unsecure external source, where it can be analyzed and used to make key decisions. Unidirectional communication ensures no data is able to leave the classified area.


  • Maintain integrity of data in secured area
  • Block classified data from leaking out of the secured area
  • Allow databases to be updated with current information

Software based data encryption provides an excellent method of providing data security between networks, but if you are looking for the peace of mind only found in physical layer data security, then cost-effective unidirectional media converters offer the exact solution you are looking for.

Transition Networks offers unidirectional data transmission in three versions of our Gigabit Ethernet Mini Media Converters: enterprise grade, hardened, and PoE-powered unidirectional media converters. All versions of these unidirectional converters are used in pairs, with a transmitting converter at one end and a receiving converter at the other end. These converters provide a 10/100/1000Base-T RJ-45 port for the copper connection and a 100/1000Mbps open SFP slot for the fiber connection.

Fiber Conservation and Optimization

Coarse wavelength division multiplexing (CWDM) solutions increase the bandwidth of embedded fiber by multiplexing multiple optical signals on a pair of single mode fiber optic strands, offering up to 16 times the capacity over the existing fiber infrastructure. The modular design is cost effective, supports multiple protocols, and is a passive solution that requires no complex configuration and little to no change to network design.

on a different wavelength.



Extend Surveillance and Control Access Even in Remote Locations

Government agencies are increasingly challenged by needs for security, surveillance, and access control for law enforcement, national security, and the protection of proprietary information. As a result, government security networks have increased in number, size, and scope. Transition Networks’ fiber integration solutions can help overcome the distance limitations of copper-based networks and offer security network designers more options with fiber optic cabling.

As security systems have evolved from analog cameras to digital, so has the technology to enable remote monitoring and the capability for security networks to reach nearly any remote location. Power-over-Ethernet (PoE) devices power equipment through the same UTP cable being used to transmit the data signal. This enables cameras, access controls and other powered devices to be installed and used in locations that were previously unavailable due to lack of, or cost of, standard power. Transition Networks’ line of PoE/PoE+/PoE++ switches, media converters, Ethernet Extenders, and PoE injectors assist in expanding the function and coverage of security and surveillance networks.

Often times, applications require equipment to be used outside of an office environment. This may include lamp posts, parking areas, or along highways. Transition Networks offers a line of hardened grade media converters and switches. These products are rated for extended temperatures and their ability to handle the increased dust and moisture associated with outdoor environments. By using hardened products, the restrictions and limitations of UTP or coaxial cable can be overcome, even in harsh outdoor environments.

Advanced access control systems, such as IP-based keypads, biometrics, smart cards, and radio frequency over Ethernet networks, transmit complex information that offers unprecedented security. The information being communicated requires additional management control that traditional rapid serial interfaces and terminal blocks can’t accommodate. Transition Networks’ range of PoE/PoE+/PoE++ devices provide the option to integrate fiber optics and Ethernet protocol when necessary to expand bandwidth and extend the distance of the network, allowing for growth of advanced access control networks.
