Axis 01857-001 Long Range PoE Network Extender
The Axis 01857-001 is an in-line PoE extender engineered to push power and Ethernet data up to 1000 meters (3280 feet) in outdoor surveillance and access control deployments. Standard PoE runs max out around 100 meters; the 01857-001 bridges that gap without requiring additional electrical service or secondary power infrastructure at the remote end. Built for warehouse perimeters, campus networks, and traffic control sites where camera or reader placement often sits far beyond standard switch reach.
Key Features
- 1000-Meter Extended Range: Transmits PoE and network data over CAT5e or CAT6 cabling to 1000 meters—eliminates the need for a second power source at the remote device, cutting installation labor and electrical permits. Actual range depends on cable quality and load; always test runs longer than 500 meters with your specific cabling and device power requirements.
- Dual PoE Standard Support: Handles both IEEE 802.3af (Type 1 Class 3) and IEEE 802.3at (Type 2 Class 4) devices transparently. Input and output remain on the same standard—so an 802.3af camera on the input line receives 802.3af at the output, preserving power budget across the run.
- Transparent Pass-Through Design: No configuration required. Plug it inline between your switch and remote camera or access reader—no firmware updates, no CLI, no learning curve. Both network and power pass through unmodified.
- IP66 Outdoor Rating: Aluminium chassis and PVC-free construction handle direct rain, dust, and spray without corrosion. Operating range of -40°C to +70°C (-40°F to 158°F) covers arctic cold-storage facilities and desert heat equally. Skip this product only if you need full submersion—that requires IP67 or higher.
- Minimal Power Draw: Device itself consumes only 1.0 W, so it won't strain your main switch's PoE budget—a critical advantage when running dozens of extenders across a large campus or perimeter.
- Compact Form Factor: 120 × 36 × 23 mm and 100 grams mean it fits inside most weatherproof enclosures or mounts directly to DIN rail. Small size reduces field installation complexity and cost.
- LED Status Indicators: Network and power LEDs show link status and device health at a glance—critical for troubleshooting long runs where you can't see the remote end visually.
- 100 Base-TX / 10 Base-T Data Rate: Supports standard Fast Ethernet speeds. Not a gigabit device—if you need 1000Base-T, look elsewhere—but Fast Ethernet is sufficient for single-camera or multi-reader runs and keeps cost down.
Integration & Compatibility
The 01857-001 works with any IEEE 802.3af or 802.3at powered device: Axis IP cameras, door readers, wireless access points, emergency intercoms, and industrial IoT sensors. No vendor lock-in. Install it as a bridge in your existing cabling topology—it passes Ethernet frames and power transparently, making it compatible with network video recorders, ONVIF-compliant VMS platforms, and standard PoE switches from any manufacturer.
Supports RJ45 network connections and includes a 2-pin DC power connector for optional 57 V DC input if you need to bypass PoE injection at the source. EMC certifications (EN 55032 Class A, EN 55024, EN 50121-4) and safety standards (IEC/EN/UL 62368-1) ensure it won't introduce electromagnetic interference into sensitive surveillance or access control networks. NEMA TS 2-2016 compliance is valuable if you're integrating into traffic control systems.
When to Choose a Different Model
If your remote device requires more than 15.4 W of power (802.3at maximum), the 01857-001 cannot deliver it—you'll need a separate power supply at the remote site. If you need gigabit speeds (1000 Base-T), this extender maxes out at Fast Ethernet and is not suitable. For runs exceeding 1000 meters, consider fiber optic media converters paired with fiber cable runs instead. If your camera or device is already powered separately, a standard unmanaged network switch rated for outdoor use may suffice.
Frequently Asked Questions
Q: What's the maximum power delivery at 1000 meters?
A: The 01857-001 preserves the input PoE standard (802.3af or 802.3at) at the output. At 1000 meters on CAT5e, voltage drop increases significantly; devices rated for lower minimum voltage (e.g., 36 V) may underperform. Always test your specific cable and device before full deployment. For power-hungry devices, reduce cable run length or add a second extender stage.
Q: Does the 01857-001 require power injectors at both ends?
A: Only at the source (camera or upstream switch). The extender's input accepts PoE from your switch or injector, regenerates it, and outputs it to the remote device. No power source needed at the remote end—that's the whole point.
Q: Can I daisy-chain multiple 01857-001 units?
A: Technically yes, but each stage introduces voltage drop and signal delay. Two units back-to-back can push 2000 meters, but testing is essential. Beyond 2000 meters, fiber media converters are more reliable.
Q: What's the warranty on the 01857-001?
A: Five-year manufacturer warranty covers defects in materials and workmanship. Does not cover damage from lightning strikes or improper installation.
Q: Is the 01857-001 NDAA Section 889 compliant?
A: Axis products are manufactured in Sweden and comply with NDAA requirements. Verify with your procurement office for specific government contract requirements.
Q: Does it support gigabit Ethernet (1000Base-T)?
A: No. The 01857-001 operates at Fast Ethernet speeds (100 Base-TX / 10 Base-T). If you need gigabit throughput over extended distances, use fiber optic converters or investigate PoE-enabled gigabit extenders from other manufacturers.

I spec the 01857-001 (often searched as 01857 001) into perimeter builds where standard 100-meter PoE limits become a real constraint. The headline feature is obvious—1000 meters of range—but the real win is that it's transparent. Zero config, zero firmware, zero headaches. Plug it in between your switch and a distant gate reader or bullet camera, and it just works.
Technical Highlights:
- 1000m Extended Reach: Standard PoE tops out around 100 meters due to voltage drop over long cable runs. The 01857-001 regenerates the signal, pushing usable distance to 1000 meters on CAT5e—that's a 10x multiplier on deployment flexibility and eliminates the electrical contractor call to run new power service to a remote corner of your site.
- 802.3af / 802.3at Dual Support: It passes the input standard straight to the output, so a 15.4W 802.3at camera stays at 802.3at after a 1000-meter run. Critical for power budgeting—you don't accidentally downgrade a device to 802.3af specs halfway through the cable.
- 1.0W Device Draw: The extender itself sips power, leaving nearly all your PoE budget for the remote camera or reader. On a 95W switch with 8 ports, you can run 6–7 powered devices plus multiple extenders without hitting the power limit.
- IP66 & -40°C to +70°C: Solid outdoor spec. The aluminum chassis won't rust, and the temperature range covers Minnesota winter and Arizona summer equally. Skip if you're mounting it in a flooded pit (IP67 needed); otherwise, weatherproof enclosure mounting or DIN rail install in a NEMA box is straightforward.
Deployment Considerations:
- Voltage Drop Scales with Distance: At 500 meters, voltage drop is modest. At 1000 meters on marginal CAT5e, your 48V input may only deliver 42–44V at the remote end. Devices with 36V minimum specs will work; devices expecting 42V or higher get dicey. Always pilot-test the exact cable and device combination before rolling out across a hundred-camera campus.
- Fast Ethernet Only: This is 100 Base-TX, not gigabit. If your VMS is streaming H.265 multicamera feeds back through the same cable, you might saturate the link. For high-bandwidth backhaul, use a separate gigabit fiber run or add a second Ethernet pair.
- Daisy-Chaining Incurs Penalty: Two extenders back-to-back work, but each adds ~1–2V of internal drop. Beyond 1500 meters, fiber converters become more reliable than cascaded units.
Deploy the 01857-001 when you've got a single long camera run or reader circuit that sits beyond a standard switch's PoE distance. Campus perimeters, warehouse loading docks, and traffic control sites are ideal. Not a catchall for every extended-distance need—but for that specific job, it solves the problem without calling in electricians or adding switch enclosures in the field.
