New Single Port PoE+ Injector Provides up to 25.5 Watts of Power to Network Devices
Transition Networks Inc., the switching and conversion technology expert, today announced the release of a single port 10/100/1000 PoE+ injector. This new, mid-span injector is capable of supplying up to 25.5W of power to network devices when used in conjunction with standard Ethernet switches.
The L1000i-at is suitable for both Security and Enterprise deployments where the cabling infrastructure is used to introduce power to the network. Built to the IEEE 802.3at PoE+ standard, this product provides a higher level of power, up to 25.5W, than is available from standard Power over Ethernet (PoE) injectors (15.4W). This higher wattage is required by many PTZ (Pan/Tilt/Zoom) network cameras, 802.11n Gigabit wireless access points, and other wireless network equipment deployed today.

Barcelona City Hall relied on engineering solutions and support from Anixter Spain and Transition Networks to install a new traffic control system and camera network, while improving services for residents.
Barcelona City Hall was searching for innovative methods to implement new technologies and improve services for residents. The decision makers had a goal to completely overhaul the existing communication infrastructure and replace it with a versatile, reliable and cost-effective solution. The project removed copper wiring in favor of implementing fiber optic rings connected to a L3 central ring at the city hall.
Transition Networks provided two types of devices, distributed by Anixter Spain, based on their implementation on remote nodes (particularly, MIL-SM8002TG access nodes) and aggregation nodes (SM24-1000SFP-AH). Among other applications, this equipment provides differentiated services in traffic light control, such as bandwidth rate limiting, class of service per port (CoS); CLI switch management via control panel port or Telnet and built in web BUI interface. It also offers SNMP v1, v2c, v3 management and dual firmware updating via TFTP/FTP/X modem server. Additional features include port duplication and robust security using RADIUS/TACACS+ authentication.
The new City Hall traffic control and camera system, now fully operational, provides robust quality of services, secure access for both authentication and public Internet access and strong remote network management via SNMP. From a centralized location, network administrators now have full visibility and remote monitoring capabilities which are key criteria for supporting the new Barcelona City Hall network.

I recently signed up for Netflix streaming service. I have both an Apple iPhone and iPad in my home, and sometimes both are streaming video. This is just the tip of the iceberg of the coming explosion of wireless data. What technologies will enable the brave new world of wireless network connectivity everywhere?
I have written in the past (“Network-Powering Next Generation Network Devices“) about two important trends influencing manufacturers’ introduction of next generation VoIP phones and streaming video cameras: PoE (Power over Ethernet) and Gigabit speeds. In addition, newer wireless technologies such as WiMAX and IEEE 802.11n will demand both Gigabit speeds and higher power. The latter is needed to enable Multiple Input Multiple Output (MIMO) antenna diversity.
Transition Networks is introducing a slew of next generation Power-over-Ethernet Plus (PoE+) switches, media converters and injectors, all of which will support Gigabit speeds. As data transfer speeds increase - power requirements of devices also rise, driving the need for a higher Power-over-Ethernet standard: IEEE 802.3at.
How does IEEE 802.3at differ from IEEE 802.3af? The newer IEEE 802.3at standard roughly doubles the power capacity which can be delivered to an end Powered Device (PD), from 12.95 watts to 25.5 watts. All the while PoE+ maintains the voltage levels in the Cat 5/6 cables to < 58 VDC (nominally just a few volts higher than PoE). Thus, PoE+ poses no shock hazards to installers.
Besides an increase in supplied power to end PDs, IEEE 802.3at PoE+ adds intelligence. A new 2-event power classification scheme and support for LLDP (Link Layer Discovery Protocol) allows devices to dynamically adjust demanded power budgets. This latter intelligence will become a key enabling technology for Intelligent Buildings and the Smart Grid.
Stay on the look out for more information on Transition’s PoE+ offering as more and more products are officially released.

Transition Networks engineers the most reliable fiber integration technology for hardened or industrial environments – bringing the security, intelligence and global support to manage your network for a lifetime.
We’ve all been witness to the amazing capabilities of Ethernet as it has progressed from a simple LAN environment to full scale Telco and Industrial networks. New developments and standards are continuously being updated and applied to Ethernet, which are accelerating its use in numerous industrial networking environments. As a result, Industrial Ethernet is now adding significant value in industrial automation achitecture by streamlining its communication and interfaces while simplifying the integration of industrial and process networks into company’s enterprise networks.
Transition is committed to bridging the gaps between the multitudes of protocols found in the controlled industrial environment. TN now offers several choices of equipment across many different applications, including: Class 1, Div 2 for hazardous locations, 99.999% uptime automation environments, and extra security measures to ensure that your data is safe. In addition, many of our switch and media converters have redundant power supply capabilities, with 24 VDC power sources, PoE/PoE+ features, and hardened components built to withstand industrial environments.
Click here to learn more about how Transition’s Industrial Networking portfolio can help you build communication networks for industrial applications, like: Oil & Gas, Automation, Utilities, Transportation and Outdoor Surveillance.

xTGFF as a Service Provider Demarcation Point
The 10GbE media converter family, the xTGFF, is designed to offer an effective, yet inexpensive demarcation point for service providers. Two of the more common applications for the 10GbE converter are:
1) Co-location managers looking to move a 10GbE connection from one side of a datacenter where a telecom demarked to a customer’s equipment rack beyond the reach of copper cabling.

2) Content service providers looking to drop a 10GbE signal to a customer requiring high-bandwidth.

In both instances, the flexibility and ease of use of the interfaces available through the xTGFF line allow for low cost, low latency demarcation devices to be used instead of expensive 10GbE capable multi-port switches and routers.
