Transition Networks’ Ethernet over coax extender with PoE+

Transition Networks’ Ethernet Over Coax Extenders with PoE+ are billed as a flexible and cost-effective way to extend Ethernet networks at near Gigabit speeds and provide full PoE+ power to security cameras, wireless access points or other IP devices using existing coaxial cabling infrastructure. The extenders work in pairs, with the local extender (EOCPSE4020-110) transmitting power and data over coax to the remote extender (EOCPD4020-110), which, in turn, provides data and power to the connected IP device. A 10/100/1000Base-T RJ-45 or 100/1000Base-X SFP combo port offers network connection flexibility, and near-Gigabit communication speeds provide sufficient bandwidth for many applications. According to the company, “The Ethernet Over Coax Extenders With PoE+ allow for quick and easy analog-to-IP security network upgrades using safety extra low voltage classification for power, avoiding the need to run new cabling or hire electricians to install new power at edge locations."

Ultra PoE device converts media, delivers 60W

Black Box’s Industrial UPoE media converter seamlessly and transparently converts 10-/100-/1000-Mbit/sec copper to 1000-Mbit/sec fiber transmission. Because it is a Layer 2 media converter, it automatically senses and adapts to speed on the copper side for true plug-and-play operation, adds the company. Housed in an IP30-rated case that can be DIN mounted, the converter features one 10-/100-/1000-Mbit/sec RJ-45 UTP port and one 1000Base-X SFP port. Supporting both multimode and singlemode fiber, the device sends power over all four pairs of Category 5e/6 cabling. Depending on the SFP, the unit can drive singlemode signals up to 50 miles (80 km). Whether used to power security cameras, wireless access points, alarms, traffic controllers, sensors, monitoring devices, or other PoE equipment, the Ultra PoE media converter delivers 60 watts of power, while power available at the PD is 50 watts.

Tripp Lite’s Gigabit Ethernet multimode media converter

Tripp Lite’s 10/100/1000 LC Multimode Media Converter allows the user to extend a Category 5e UTP Ethernet connection up to 550 meters over multimode fiber-optic cable. The company says the converter “provides an economical solution for network connectivity to nodes located in isolated corners or separate buildings of a corporate campus or university.” The unit autonegotiates MDI/MDI-X port connections and senses network speed automatically on the UTP port. It also auto-detects full- or half-duplex operation on the fiber port. This converter uses the 850-nm wavelength and supports multimode 50/125 cable up to 550 m (1804 ft) or 62.5/125 cable up to 400 m (1312 ft). The input port has a female RJ-45 connector and the output port has a female LC duplex connector. Six LEDs provide performance monitoring at a glance. Power is supplied by a compact AC adapter.

Industrial Ethernet-to-fiber bit driver

The Industrial Ethernet to Fiber Optic Bit Driver from S.I. Tech Inc. is a 4x3.6x1.2-inch device containing one 10/100-Mbit/sec Ethernet port and one fiber port. The fiber port can be multimode, for shorter distances, or singlemode, for longer distances, the company points out. The multimode version of the bit driver comes with ST interfaces; the singlemode version comes with SC interfaces standard, with LC interfaces optional. The device can be DIN-rail mounted, with redundant 10- to 32-VDC power input, which is commonly found in industrial plants. The Ethernet board is conformal coated for protection from dust, dirt and humidity, S.I. Tech notes. The enclosure is IP-40 rated. The Industrial Ethernet to Fiber Optic Bit Driver (Model 2151) supports the IEEE 802.3 specification MDI using autonegotiation or a manual setting. Status indicators ease troubleshooting power/link status/LAN activity/data speed. The device can be used with straight- or cross-wired Ethernet cables.

Multi-port PoE+ media converter

Omnitron Systems’ OmniConverter GPoE+/SX is a multi-port Power over Ethernet Gigabit media converter with switching capabilities. It features four 10/100/1000-Mbit/sec RJ-45 ports that are capable of delivering 15.04W or 34.20W of PoE, as well as one or two fiber ports that support Gigabit or Fast Ethernet transceivers. The GPoE+/SX supports several networking modes for distributing traffic, including directed switch mode that prevents network congestion, and multiplexer mode that isolates secure data streams for different cameras in multi-user surveillance applications. Models with two fiber ports support dual device mode, which enables the GPoE+/SX to operate as two independent PoE media converters. The two fiber ports also facilitate daisy-chain topologies and redundant fiber links with less than 50-ms failover. Models are available with SC, ST and LC fixed-fiber connectors, or with SFP transceivers at 100-Mbit/sec or Gigabit data rates in multimode, singlemode, and a variety of CWDM and DWDM wavelengths.
