Transition Networks Introduces PoE+ Media Converters
Transition Networks Inc. has come out with a new family of gigabit Ethernet power over Ethernet Plus media converters. These devices were designed for such applications as connecting devices like cameras and Wi-Fi access points over fiber,
creating small remote workgroups, and connecting multiple remote systems to a fiber switch connection.
The new products include two-, three-, and four-port devices, all of which comply with the IEEE 802.3at PoE+ standard and deliver 56VDC power so there’s no need to run power to remove devices. They also include Active Link Pass Through and Auto Power Reset features, which are designed to make it easy for admins to manage link failures and reset power.
“These products are really the templates for next-generation media converters that need to excel at physical layer PoE+ connectivity but also have some network intelligence – like Layer 2 switching – for added convenience and flexibility,” said Curt Carlson, product manager with Transition Networks, with sells an array of data network integration products.
Other companies in the marketplace with PoE media converters include Antaira
Advantech, B&B, Black Box, Interlogix, Moxa, Omnitron Systems, Perle,
Startech, and Volktek.
PoE has been around for a long while with proprietary, and often non-interoperable, implementations from various vendors to power devices. Perle explains in technical notes on its website. But in June 2003, the IEEE ratified the 802.3af PoE standard, which started the move to standard-compliant products in the PoE realm.
“In 2009, the IEEE ratified the 802.3at PoE Standard, commonly known as PoE+,” Perle said. “Using these standards, organizations deploy equipment in locations that are difficult or too costly to have separate AC power installed – such as ceilings, walls and kiosks.”
These inline power solutions, it added, significantly reduce the number of wires that must be strung to install a network. And they deliver greater flexibility in where equipment can be installed, less downtime, and decreased wiring and power costs.
