PoLRE Switch


The PoLRE switch delivers Ethernet and Power over Ethernet over a single pair of wire with up to 1,200ft (365m) reach. This means you can transform your existing, proven reliable voice wiring infrastructure into an IP path ideal for IP Telephony complementing and extending your existing data LAN.

Over 300,000 users have leveraged PoLRE technology to migrate to an all IP Platform avoiding risk, cost, disruption and complexity.  With PoLRE an all IP platform is easily achieved.

Uses for Phybridge PoLRE: 

  • IP Telephony
  • IP wireless access points
  • IP cameras
  • IP speakers
  • Any IEEE compliant device 

Introducing PowerWISE, Another Industry First
PoLRE switches come standard with PowerWISE technology, providing the flexibility to use either AC or DC power sources with the same switches. Power sharing, load balancing, hot swappable power supply, AC/DC options — the PoLRE switches are amongst the lowest power consuming data switches in the industry. A highly-reliable local area switch network powered by PowerWISE with multiple sources of redundancy allows for the most robust PoE platform in the industry.


Lower Total Cost of Ownership. No network assessments, no rip and replacing of the infrastructure, no expensive environmental considerations for distributed closets and best of all, no financial risk. As a result, companies can allocate more of their available budget on applications and application adoption driving a better overall return on investment.

Low Risk, Quick & Easy to Deploy. A ‘plug and play’ deployment strategy combined with leveraging an existing proven reliable infrastructure allows customers to confidently install a Phybridge backbone. You can quickly migrate to IP telephony saving time while minimizing network and business disruption.

Optimized Converged Local Area Network. The single point of central convergence and the dedicated voice path for each IP phone results in the most robust, reliable and secure topology achievable. Voice quality of service, voice continuity and a highly secure topology come standard with Phybridge.

Network Redundancy and Resilience.  PoLRE switches are designed to ensure uptime and availability.   The PoLRE PowerWISE features providers load sharing, power sharing, load balancing and AC/DC power flexibility to create redundancy.  Unlike many other data switches, the PoLRE switch was also designed to maintain connectivity even when the software fails. 

Simple Network Management. The physical separation of voice traffic combined with user friendly management GUI eliminates the complexities of managing a LAN topology with ever changing voice, video, and data traffic sharing a single path. By giving real-time voice applications a dedicated physical path, your IT staff can easily manage their network ensuring quality of service regardless of network loads.

Beyond Convergence Made Simple. The data needs of a business constantly evolve with data LANs changing every 3 to 5 years. You will save money while eliminating change management risk knowing you have a dedicated Phybridge infrastructure supporting the bandwidth and power needs for your IP phones. A move to gigabit to support the evolving data needs of users does not require you to buy expensive gigabit phones or POE data switches resulting in significant future savings.

PoLRE PL-024/PL-048 leverages telephone cabling infrastructure to create a parallel network with Power-over-Ethernet. This is a plug-and-play solution that can be deployed quickly and easily with the default configuration.
