Black Box LPR1111 PoE Repeater / PoE Extender

Overview

The Black Box LPR1111 is a PoE repeater designed to extend network and power reach beyond the standard 100-meter Ethernet distance limit — a common constraint in camera deployments where the closest switch is too far from the mounting location. By acting as an inline PoE extender, the LPR1111 allows you to push both data and power to a downstream device without running a second power source to the endpoint. This matters most in corridor, stairwell, parking structure, and perimeter installations where conduit runs are long and power outlets are scarce.

Key Features

• PoE Pass-Through: Accepts PoE input from your upstream switch and delivers PoE output to the downstream device — no local AC power outlet required at the extension point, which simplifies installation in finished ceilings and concrete structures.
• Extends Ethernet Distance: Breaks the 100m copper Ethernet barrier by regenerating the signal, giving you a fresh 100m segment on the output side — critical when camera mounting locations are dictated by sight lines, not cable math.
• Inline Form Factor: Designed to sit between your switch and endpoint device without requiring rack space or additional configuration — wire it in and it works.
• PoE Connectivity: Both input and output connections are PoE-capable, making the LPR1111 compatible with standard PoE-powered endpoints including IP cameras, access control readers, and VoIP phones.

Integration & Compatibility

The LPR1111 is compatible with any PoE-capable switch on the input side and any standard PoE-powered device on the output side. Verify that your upstream switch's per-port power budget covers both the extender's overhead and the downstream device's draw — underpowered ports are the most common deployment issue with inline PoE extenders. For guidance on sizing your switch infrastructure, see the PoE switches category. The Black Box networking line includes complementary media converters, patch panels, and structured cabling accessories that pair naturally with the LPR1111 in extended-run architectures. If you are planning a full camera infrastructure, review IP cameras compatible with standard PoE to ensure end-to-end power compatibility.

Frequently Asked Questions

Q: What does the Black Box LPR1111 actually do?

A: The LPR1111 is a PoE repeater that extends both the Ethernet data signal and PoE power beyond the standard 100-meter copper limit, allowing you to reach distant endpoints without a local power source at the extension point.

Q: Does the LPR1111 require its own power supply?

A: No. The LPR1111 draws power from the upstream PoE port and passes power downstream — no separate AC adapter or outlet is needed at the installation point.

Q: What devices can I connect to the output of the LPR1111?

A: Any standard PoE-powered device — IP cameras, access control readers, VoIP phones, or wireless access points — can connect to the LPR1111 output, provided your upstream switch port delivers sufficient wattage to cover both the extender and the downstream load.

Q: How many LPR1111 units can I chain together?

A: The manufacturer's documentation should be consulted for maximum chaining specifications. Contact pre-sales engineering for configuration guidance on multi-hop deployments.

Karl Wilson

The LPR1111's value proposition is straightforward: PoE in, PoE out, with an Ethernet signal regeneration stage in between that resets the 100m distance clock. I reach for this kind of inline extender when a camera mounting location is dictated by coverage geometry — a stairwell landing, a far corner of a parking deck — and the nearest IDF is 130 or 150 meters away. Running conduit back to a closer switch costs more than the extender itself.

Technical Highlights:

• PoE Input/Output: Both ports carry PoE, so the upstream switch powers the extender and the downstream camera in a single wire run — no junction box AC tap required at the wall.
• Signal Regeneration: Unlike a passive coupler, the LPR1111 actively regenerates the Ethernet signal, giving the downstream segment a clean 100m budget rather than splitting a degraded one.
• Inline Deployment: No rack unit, no configuration interface, no management overhead — install it in a ceiling tile or surface-mount enclosure and it is transparent to both the switch and the endpoint.

Deployment Considerations:

• Confirm your upstream switch port's per-port power budget before deploying — the extender consumes wattage itself before passing any power downstream. An 802.3af (15.4W) port may leave insufficient headroom for a PoE+ camera on the output.
• Available evidence does not include confirmed maximum chaining depth, PoE standard (802.3af vs. 802.3at), or output wattage figures — verify these against the Black Box datasheet before specifying in a multi-hop design.

The LPR1111 is best positioned for perimeter or parking structure camera runs where mounting locations are fixed by coverage requirements and IDF distance makes a direct home-run cable cost-prohibitive — specifically when the alternative is trenching conduit or adding a remote switch cabinet.
