NOVKER NK120 + NK200 Fiber Optic Testing Kit for Network and CCTV Technicians Malaysia
NOVKER NK120 + NK200 Fiber Optic Testing Kit for Network and CCTV Technicians Malaysia
For technicians who regularly handle fiber optic installation, CCTV networking and maintenance work, a useful basic testing combination is:
NOVKER NK120 15mW Visual Fault Locator + NOVKER NK200 Optical Power Meter
The two instruments perform different functions.
NK120 → Visual fiber tracing and physical fault checking
NK200 → Optical power measurement
Together, they provide technicians with a practical starting toolkit for everyday fiber optic troubleshooting in Malaysia.
Why Combine NOVKER NK120 and NK200?
A fiber link can fail for many reasons.
The problem may involve a damaged patch cord, excessive bend, incorrect fiber connection, connector issue, low optical power or a fault somewhere along the installed cable route.
This means technicians often need more than one type of test.
The NK120 provides visual troubleshooting capability, while the NK200 adds optical measurement capability.
Instead of expecting one tester to solve every problem, technicians can use the appropriate instrument for each stage of troubleshooting.
NOVKER NK120 – 15mW Visual Fault Locator
The NOVKER NK120 is a Visual Fault Locator designed to inject visible red laser light into an optical fiber.
Key supplied configuration:
Model: NOVKER NK120
Type: Visual Fault Locator
Specified Output: 15mW
Power: Lithium Battery
The NK120 can assist technicians with fiber identification, continuity checking and investigation of certain accessible physical fiber faults.
What Can the NK120 Help You Find?
A VFL is particularly useful when the problem can potentially be identified visually.
For example, technicians may use the NK120 when investigating:
Fiber Breaks
Certain physical breaks may allow visible red light to escape from the damaged area.
Severe Fiber Bends
An excessively bent fiber may sometimes show visible light leakage.
Damaged Patch Cords
Accessible patch cords are suitable candidates for preliminary VFL checking.
Fiber Identification
Visible red light can assist technicians in identifying the corresponding fiber at another accessible termination point.
Installation Errors
A VFL can help with basic checking during installation and commissioning.
However, visibility depends on the fiber, cable construction, fault type, ambient conditions and accessibility.
A VFL should not be expected to reveal every fiber problem.
NOVKER NK200 – Optical Power Meter
The NOVKER NK200 Optical Power Meter performs a different job.
Instead of visually locating certain physical faults, an Optical Power Meter is used when the technician needs to measure optical power.
This is important because a fiber can appear physically normal but still have a signal-related problem.
The NK120 cannot provide an optical power measurement.
That is where the NK200 becomes useful.
NK120 + NK200 – Two Tools, Two Functions
| Testing Requirement | NK120 VFL | NK200 OPM |
|---|---|---|
| Visible Fiber Tracing | Yes | No |
| Fiber Identification | Useful | Not primary purpose |
| Continuity Checking | Useful | Different function |
| Visible Break Checking | Useful | No |
| Severe Bend Investigation | Useful | Can assist through measurement |
| Optical Power Measurement | No | Yes |
| OTDR Event Location | No | No |
Together, the NK120 and NK200 provide a broader troubleshooting capability than either instrument alone.
Example – CCTV System Connected by Fiber
Consider a CCTV installation with cameras located in another building.
The network configuration might be:
IP Cameras
↓
PoE Switch
↓
Fiber Link
↓
Main Network Switch
↓
NVR / Control Room
One day, the remote CCTV network becomes disconnected.
Where should the technician start?
Step 1 – Check the Network Equipment
Before assuming that the fiber is damaged, inspect the network equipment, power supplies, connectors and patch cords.
Step 2 – Use the NK120 VFL
The technician can use the NK120 to help identify the correct fiber and investigate accessible physical faults.
Patch cords, termination points and accessible cable sections can be checked.
Step 3 – Use the NK200
If optical power measurement is required, the NK200 can be used as part of the troubleshooting process.
This gives the technician measurement information that a VFL cannot provide.
Step 4 – Use More Advanced Equipment if Necessary
If the problem is somewhere along a long or inaccessible fiber route, the technician may need an OTDR.
This creates a logical troubleshooting progression:
Visual Inspection → NK120 VFL → NK200 OPM → OTDR
The exact procedure should always depend on the network and fault conditions.
Why NK120 for Regular Technicians?
Compared with the NK100, the NK120 is the higher specified VFL option in this NOVKER range.
| Feature | NK100 | NK120 |
|---|---|---|
| Specified Output | 10mW | 15mW |
| Battery | Dry Battery | Lithium Battery |
| Visual Fiber Checking | Yes | Yes |
| Pair with NK200 | Yes | Yes |
| Positioning | Basic / Entry-Level | Higher-Spec |
The NK100 remains useful for basic and occasional applications.
The NK120 can be considered by technicians who prefer its 15mW lithium-battery configuration.
Higher specified mW does not mean that every fault will be visible over a particular distance. Actual results depend on the fiber, cable construction, connections, fault condition and environment.
Who Can Use the NK120 + NK200 Combination?
The combination is relevant to several types of users in Malaysia.
CCTV Installers
Modern CCTV projects may use fiber between buildings or over longer network routes.
CCTV technicians who previously worked mainly with Ethernet may therefore need basic fiber troubleshooting equipment.
Network Contractors
Network installers increasingly handle both copper and fiber infrastructure.
A VFL and Optical Power Meter provide two useful fiber-testing functions in a compact toolkit.
IT Maintenance Teams
Companies with internal fiber connections may want basic equipment available for preliminary troubleshooting.
Factory Maintenance Teams
Factories may use fiber between production areas, control rooms, server rooms and different buildings.
Basic fiber testing equipment can help maintenance personnel perform initial checks.
Fiber Installation Contractors
Technicians performing installation work can keep a VFL and OPM available for routine field checks.
When Is NK120 + NK200 Not Enough?
The combination is useful, but it should not be treated as a complete replacement for advanced fiber testing equipment.
Suppose the customer says:
“The fiber cable is 2 km long and we need to know where the fault is.”
The NK120 cannot provide a distance-to-fault reading.
The NK200 measures optical power but does not provide OTDR-style event location.
An OTDR is therefore a more appropriate instrument when technicians need detailed analysis of events along the fiber.
Adding the NOVKER NK420 Fiber Identifier
Technicians handling more complex fiber networks can also consider the NOVKER NK420 Fiber Identifier.
The toolkit can then expand to:
NOVKER NK120
Visual Fault Locator
NOVKER NK200
Optical Power Meter
NOVKER NK420
Fiber Identifier
Pocket OTDR
Advanced fiber fault analysis
Rather than purchasing every instrument immediately, contractors can expand their equipment according to actual project requirements.
A Practical Fiber Toolkit for Growing Contractors
For a contractor moving from normal LAN or CCTV work into fiber, equipment can be added progressively.
Stage 1 – Basic Visual Checking
NOVKER NK120 VFL
Stage 2 – Add Measurement
NK120 + NK200
Stage 3 – Expand Fiber Identification
NK120 + NK200 + NK420
Stage 4 – Advanced Troubleshooting
VFL + OPM + Fiber Identifier + OTDR
This approach allows technicians to build capability as the number and complexity of fiber jobs increase.
NK120 + NK200 for Data Centre and Server Room Maintenance
Fiber connections are common in server rooms, communication rooms and data centre environments.
A VFL can be useful for basic tracing and accessible physical checks, while an Optical Power Meter adds measurement capability.
For more complex infrastructure, these instruments should form part of a wider testing procedure rather than being treated as complete diagnostic solutions.
Important Laser Safety
The NOVKER NK120 is a laser device.
Never look directly into the VFL output port.
Never look directly into the end of a connected fiber while the VFL is operating.
Never point the laser toward another person's eyes.
Always follow the manufacturer's operating instructions and appropriate laser-safety procedures.
