GE's Power Express Distribution Shelf Improves Installation Process of Distributed Antenna Systems

  • Reduces Time, Resources and Cost Required for Installation Process
  • Field Replacements are Quick and Cost-Effective with Pluggable Modules

LAS VEGAS – April 30, 2013 - GE (NYSE: GE) today unveiled its new Power Express Class 2 distribution shelf to equip wireless network providers with a solution to reduce the footprint of distributed antenna systems' (DAS) power cables. This distribution shelf eliminates the need for installing expensive conduit to run the cables. The announcement was made at DAS Congress in Las Vegas.

"Telecommunication technology advancements have led to an exponential growth in the number of sophisticated mobile devices operating across the globe. These devices provide consumers with endless communication and data tools at their fingertips; however, they also have led to concerns over how much bandwidth a wireless provider's network can facilitate," said Jeff Schnitzer, general manager of GE's Critical Power business. "To address these bandwidth constraints, many telecom providers install a DAS, which increases network speed and provides bandwidth relief, but often requires costly infrastructure be installed to harness power cables. GE's new Power Express Class 2 distribution shelf provides telecom companies with an advanced solution to combat this problem."

The Power Express Class 2 distribution shelves enable power-feed cables to be harnessed in existing infrastructure throughout a commercial building's data cable raceway. To do this, the distribution modules located on the shelf limit individual circuit outputs to an inherently safe level by taking an input of -48 volt DC power from a battery plant and outputting it in 32 discrete 100-watt circuit cables (levels comparable to a LAN or USB data cable).

This advanced shelf incorporates internal circuit fusing to the distribution modules, which prevents technicians from installing a higher rated fuse and violating National Electric Code (NEC) Class 2 circuit requirements. This guarantees Class 2 circuit performance and inherently ensures a safe power connection. Per NEC regulations, Class 2 compliance requires that a maximum power output be equal to or less than 100 watts per component. Class 2 circuits are considered to be safer than many others.

"By delivering an inherently safe power cable complying with the National Electrical Code, the Power Express enables the wireless service provider to run through power cables in existing data cable raceways," Schnitzer continued.

In addition to internal circuit fusing, GE's Power Express utilizes pluggable modules, enabling easy removal and replacement of the units and eliminating the need to rewire the entire shelf when performing maintenance. This ability to simply plug in a replacement module to resume standard operation is a distinctive feature of GE's distribution shelf.

The Power Express distribution shelf also incorporates a proprietary data bus that allows uplink to GE's Pulsar Plus controller, providing users with a remote interface via a LAN. This enables a wireless carrier to remotely monitor and control each module on the Power Express shelf from its network operations center. The ability to power cycle the circuit modules remotely instead of having to physically go to the site can save wireless providers time and money when a reboot is needed.
