Extender offers PoE+ power over 2-wire Ethernet

Transition Networks has expanded its family of Ethernet extenders by introducing an Ethernet Over 2-Wire Extender With PoE+ to provide power and data to security cameras, wireless access points, and other IP devices at distances beyond the typical 100m Ethernet cable limitation.

The EO2PSE4052-111 (local unit) and EO2PD4052-111 (remote unit) are IEEE 802.3af/at compliant. The IEEE has just approved the 802.3bu-2016 standard for power over two-wire Ethernet links.

The extenders save time and money by leveraging existing unshielded twisted pair (UTP) cabling infrastructure to provide data and safety extra low voltage (SELV) power to IP/Ethernet devices in remote locations or at legacy sites, eliminating the need to install new cable and electrical power for upgrading, extending, or bridging networks. They are used in pairs, with a local or remote device installed at opposite ends of the UTP cable, and Transition Networks’ proprietary SELV classification method prevents power delivery to unintended devices for added safety.

The extenders are the most flexible in the market with a 10/100/1000Base-T RJ-45 or 100/1000Base-X SFP combo port allowing connection to either copper or fiber Ethernet devices. Adding to the flexibility, these extenders provide an RJ-45 and 2-wire terminal block connection to accommodate CAT 5/6, CAT 3 or 2-wires of other 18-24 AWG UTP cable. The extenders can deliver full PoE+ at distances ranging from 400 to 7,000 ft (150m to 2km depending on cable type and number of wire pairs available), and data at half-gigabit Ethernet speeds over UTP cable at distances of 660 ft (300m) or fast Ethernet speeds at 2,000 ft (600m, also depending on wire gauge). Power for the Local device can be supplied through a properly isolated +48VDC power source or through the designated 90 Watt power adapter. Power for the Remote device can be supplied with PoE from the Local unit, through a properly isolated +48VDC power source, or through the designated power adapter for providing redundant power or for additional power requirements at the Remote device.

The Ethernet Over 2-Wire Extenders With PoE+ are supplied with a web GUI, which allows password-protected access to various configuration options of both the Local and Remote devices through a
