UGREEN NW167 RJ45/RJ11 Cable Tester (10950)
Overview
UGREEN 10950 / NW167 is a two-part continuity tester for terminated network and telephone cables. A main unit sequences LEDs while the detachable remote receives the far end, helping a technician compare conductor order and identify open, short or crossed wiring. The interface specification covers RJ45 8P8C and RJ12/RJ11-family 6P6C, 6P4C and 6P2C cables. It is a wiring checker, not a network-speed, PoE-load or cable-certification instrument.

What it does well.
A continuity tester—not a network certifier
UGREEN 10950 compares conductor continuity and order on supported RJ45 and telephone cables. It does not measure Ethernet throughput, cable category compliance, PoE load, distance to a fault or network traffic. The port specification does not support BNC/coax testing, so that capability must not be assumed.
Key features
- Detachable main and remote sections for checking both ends of an installed cable run.
- RJ45 8P8C ports for shielded or unshielded Ethernet patch and installed cables.
- RJ12/RJ11-family support for 6P6C, 6P4C and 6P2C telephone wiring.
- Sequential LED indicators provide a visible conductor-order comparison.
- Fast and slow scan positions are documented in the model specification.
- Gold-plated contacts in a compact ABS/PC housing; powered by a replaceable 9 V battery.
Use scenarios
Check a newly crimped RJ45 patch lead before connecting network equipment.
Verify conductor continuity through a wall or ceiling run by separating the remote unit.
Compare telephone-cable pin order after fitting RJ11 or RJ12 plugs.
Isolate a suspected open, short or crossed conductor during basic troubleshooting.
Carry out a quick field check before using a cable; use a certifier when standards compliance must be documented.
Setup and usability guidance
Disconnect the cable from switches, routers, telephony equipment, PoE injectors and all live circuits.
Install a sound 9 V battery with correct polarity; a battery is required; confirm retail-package inclusion separately.
For a patch lead, connect one end to the matching main-unit socket and the other to the remote socket.
For an installed run, detach the remote, connect it at the far outlet and connect the main unit at the near end.
Select slow or fast mode, watch the LED order on both parts and compare it with the expected pinout before reconnecting equipment.
Compatible devices and systems
For terminated RJ45 8P8C network cables and RJ12/RJ11-family telephone cables using 6P6C, 6P4C or 6P2C wiring.
It can check conductor continuity regardless of Ethernet category when the connector fits, but it does not certify Cat5e/Cat6/Cat7/Cat8 performance.
BNC/coax capability is not by the detailed port and package specifications; no BNC socket or adapter is specified.
Real-world performance and planning
The result is a visual wiring pattern. Matching sequential LEDs indicate continuity and expected order, while missing, repeated or out-of-order indications can point to an open, short or crossed conductor. Interpretation still depends on the chosen wiring scheme; this tester does not decide whether a cable meets Cat6, Cat6A or other certification limits.
For a trustworthy check, disconnect the cable from all active equipment, verify the 9V battery, test both plugs and run the sequence more than once. When a channel must be formally certified for bandwidth, insertion loss, return loss or standards compliance, use a calibrated cable certifier after basic continuity troubleshooting.
Check before buying
Use only disconnected, de-energised RJ45 8P8C or supported 6-position telephone wiring.
A replaceable 9V rectangular battery is required; confirm retail-package inclusion separately.
Do not rely on this unit for PoE, live-line, cable-length or performance certification.
Compare the LED order with the required T568A/T568B or telephone pinout—not only whether lights appear.
Warnings and limitations
- The interface list shows RJ45 and RJ12/RJ11-family sockets only. BNC capability is unverified; choose a dedicated coax tester when BNC testing is required.
- Battery inclusion varies by retail package. Plan to supply a compatible 9V battery unless the sealed package confirms one.
- Always test de-energized cabling. This is not protective equipment and is not rated for live mains, active PoE or telephone ringing voltage.
- A continuity pass proves conductor mapping only; it does not prove the run will sustain a claimed network speed.

Questions buyers ask.
Can it certify a Cat6 cable?
No. It can check conductor continuity and order, but category certification requires a calibrated cable certifier that measures performance parameters.
Does it test RJ11 telephone cables?
Yes. The official detail lists 6P6C, 6P4C and 6P2C telephone wiring through the RJ12/RJ11-family socket.
Does it really test BNC coax?
Do not assume so. The detailed ports and box contents do not specify a BNC interface or adapter.
Is the 9 V battery included?
Regional UGREEN listings conflict. Treat it as not guaranteed and confirm the local retail package before purchase.
Can I connect it to a PoE switch?
No. Disconnect both ends from all powered equipment and test only an isolated cable.
What does a different LED order mean?
It usually indicates crossed or misordered conductors. Compare the main and remote sequences with the intended pinout.
Can it find the distance to a break?
No. This model does not provide time-domain reflectometry or a distance reading.
Can one person test an installed wall run?
Yes, if the far end is accessible: detach the remote, connect it at the far outlet, then operate the main unit at the near end.
Why are the LEDs weak?
Check battery charge, polarity, plug seating and contact cleanliness. Replace the 9 V battery before judging the cable.
Will a pass guarantee Gigabit Ethernet?
No. All eight conductors may be continuous while impedance, termination quality or interference still prevents reliable Gigabit operation.
Can I test a cable while it is connected to a switch or PoE injector?
No. Disconnect both ends from switches, routers, PoE equipment, telephone circuits and every other live source before using the tester. It is a passive continuity-check workflow and should never be connected to energised cabling.
Does it test BNC or coaxial cable?
The interface specification for model NW167 / 10950 covers RJ45 8P8C and RJ12/RJ11-family 6P6C, 6P4C and 6P2C connections. No BNC interface is specified for this model.
This description applies to UGREEN model NW167 / SKU 10950. Match both identifiers on the product or package, keep the main and remote together and retain the wiring instructions. UGREEN India after-sales eligibility follows the listing terms.
