ZS-1000A Fibre OTDR Price in Kenya

The ZS-1000A Fibre OTDR is a compact multifunctional fibre optic tester designed for installation, troubleshooting, maintenance and certification of optical fibre networks. It combines several essential fibre-testing functions in one portable instrument, including an Optical Time Domain Reflectometer (OTDR), Optical Power Meter (OPM), Optical Light Source (OLS), Visual Fault Locator (VFL) and iOLA intelligent event-analysis function. 

The ZS-1000A supports dual 1310nm and 1550nm OTDR wavelengths, a test range from approximately 100 metres to 80 kilometres, and a 20dB dynamic range. This makes it useful for FTTH networks, ISP fibre infrastructure, PON deployments, backbone links, ODF testing, fibre closures and general fibre maintenance. 

Its compact body weighs about 217g and includes a 3.5-inch high-definition touchscreen, making it significantly easier to carry in a technician's field toolkit than larger conventional OTDRs. 

ZS-1000A Key Specifications

These specifications correspond to the current compact ZS1000-A model documented by Signal Fire. 

What Is an OTDR?

OTDR stands for Optical Time Domain Reflectometer.

An OTDR sends optical pulses into a fibre and analyses the light reflected and scattered back toward the instrument.

From this information, it can help determine:

• Fibre length

• Fibre attenuation

• Location of fibre breaks

• Connector locations

• Splice locations

• Splice losses

• Reflective events

• Excessive bends

• End of fibre

• Distance to a fault

Unlike a Visual Fault Locator, which depends on visible red light, an OTDR provides a graphical trace showing what is happening throughout the fibre link.

1310nm and 1550nm Dual-Wavelength Testing

The ZS-1000A supports two important single-mode testing wavelengths:

1310nm and 1550nm.

Using both wavelengths is useful because fibre behaviour can differ between them.

A bend that appears relatively minor at 1310nm may produce noticeably greater loss at 1550nm, making dual-wavelength testing useful when diagnosing fibre problems.

Up to 80KM OTDR Test Range

The compact ZS-1000A provides an OTDR measurement range from approximately 100 metres to 80 kilometres. 

This makes it suitable for more than short subscriber drop cables.

Applications can include:

• FTTH drops

• Distribution fibre

• Feeder fibre

• Metropolitan fibre

• Campus fibre

• ISP networks

• CCTV fibre links

• Enterprise networks

• Longer point-to-point links

The actual measurable link length depends on fibre attenuation, connector losses, splitters, splices and the total optical loss budget.

20dB Dynamic Range

The ZS-1000A has a specified 20dB OTDR dynamic range. 

Dynamic range affects how much optical loss the OTDR can analyse before the returning signal becomes too weak.

For FTTH and access-network technicians, 20dB provides useful capability for many subscriber, distribution and medium-distance testing applications.

iOLA Intelligent Event Analysis

One of the most useful features of the ZS-1000A is iOLA intelligent optical link analysis.

Signal Fire specifies the iOLA function specifically for the ZS1000-A model. 

Instead of requiring the technician to interpret only a conventional OTDR waveform, iOLA can simplify the link into identifiable events.

These can include:

• Connectors

• Splices

• Fibre sections

• Excessive losses

• Fibre bends

• End of fibre

• Potential faults

This is especially useful for technicians who are still learning how to interpret conventional OTDR traces.

Traditional OTDR Trace vs iOLA

Experienced technicians can still use the conventional trace when detailed analysis is required.

Optical Power Meter

The ZS-1000A also contains a built-in Optical Power Meter.

The specified measurement range is approximately:

-50 to +26dBm

with calibration wavelengths including:

• 850nm

• 1300nm

• 1310nm

• 1490nm

• 1550nm

• 1625nm

This allows technicians to perform basic optical-power measurements without carrying a separate OPM.

Optical Light Source

The ZS-1000A incorporates an Optical Light Source (OLS) using the OTDR/OLS optical interface.

The light source can be used together with an Optical Power Meter when performing fibre loss testing.

A typical workflow is:

Optical Light Source → Fibre Link → Optical Power Meter

This helps technicians determine whether a fibre link has excessive attenuation.

Built-In 10mW Visual Fault Locator

The ZS-1000A also integrates a 10mW Visual Fault Locator using a universal 2.5mm interface. 

The VFL sends visible red light through the fibre and can help locate:

• Fibre breaks

• Severe bends

• Broken patch cords

• Damaged pigtails

• Connector problems

• Short-distance continuity faults

This is particularly convenient because technicians can perform quick visual checks without carrying another VFL pen.

3.5-Inch Touchscreen

The ZS-1000A features a 3.5-inch high-definition multi-touch screen. 

The interface provides access to functions such as:

• OTDR

• iOLA

• Optical Power Meter

• Optical Light Source

• VFL

• System settings

The touchscreen format helps make the tester easier to operate for technicians accustomed to smartphone-style interfaces.

Compact and Lightweight Design

One major advantage of the ZS-1000A is portability.

This makes the unit particularly suitable for technicians working:

• On utility poles

• Inside customer premises

• At FAT boxes

• Inside ODF rooms

• In fibre chambers

• On rooftops

• At remote ISP sites

2000mAh Rechargeable Battery

Signal Fire specifies a 2000mAh rechargeable lithium battery for the compact ZS1000 series. 

The device charges through USB Type-C, making field charging easier because technicians can use compatible power banks and chargers.

This is useful for fibre technicians who may spend an entire day away from an office or workshop.

Built-In LED Flashlight

The ZS-1000A also includes an LED illumination function. 

Although simple, this can be particularly useful when technicians are working:

• Inside dark cabinets

• At night

• Inside fibre chambers

• Behind equipment racks

• Inside poorly illuminated ODF rooms

Watch the Fibre OTDR Video

Important: the supplied video is titled “FIS Atlas Mini OTDR | Product Highlight,” so it demonstrates OTDR functionality but is not specifically a ZS-1000A product video. It can still be used as an educational OTDR video, but the page should not claim that the unit shown in the video is the ZS-1000A.

The video helps visitors understand the general purpose of an OTDR: analysing an optical fibre link and identifying events along its length. This is useful because OTDR operation is more technical than using a simple VFL or Optical Power Meter.

For the ZS-1000A specifically, the combination of OTDR, iOLA, OPM, OLS and VFL means a technician can perform several common diagnostic tasks using one compact device instead of carrying multiple separate testers. 

For FTTH technicians and ISP teams, this is particularly useful during new installations, network acceptance, subscriber troubleshooting and emergency fibre repair.

What Can the ZS-1000A Detect?

An OTDR can help identify several types of events.

ZS-1000A for FTTH Networks

The ZS-1000A is particularly useful for FTTH networks.

A typical fibre path may be:

OLT → ODF → Feeder Fibre → PLC Splitter → Distribution Fibre → FAT → Drop Cable → ATB → ONU

An OTDR can help technicians investigate faults across sections of this infrastructure.

ZS-1000A for ISP Networks

ISPs can use the tester for:

• New fibre deployment

• Fibre route verification

• Fault location

• Backbone maintenance

• Distribution network testing

• Subscriber troubleshooting

• Fibre repair verification

• Splice-quality checks

• Documentation

Testing Fibre Length

One of the fundamental OTDR functions is measuring the distance through an optical fibre.

This is useful when:

• Cable records are unavailable

• A route length needs confirmation

• A cable breaks underground

• Technicians need the distance to a fault

• Fibre documentation needs verification

The OTDR trace can indicate both the total link length and the approximate position of individual events.

Finding Fibre Breaks

Suppose a fibre cable is several kilometres long and has been damaged somewhere along the route.

A VFL may not provide enough information.

An OTDR can indicate that the break is, for example:

3.42 km from the test location

rather than forcing technicians to inspect the entire route manually.

This is one of the major reasons OTDRs are essential for professional fibre maintenance.

Testing Fusion Splices

Fusion splices should introduce very little optical loss.

An OTDR can help technicians identify unusually lossy splice events along the fibre.

This is useful when checking work completed inside:

• Fibre closures

• ODFs

• FAT boxes

• Joint boxes

• Backbone splice points

Testing Fibre Connectors

Connectors can create reflective events on an OTDR trace.

These may include:

• SC/UPC

• SC/APC

• LC/UPC

• LC/APC

• FC connectors

High reflection or excessive loss may indicate contamination, poor termination or connector damage.

ZS-1000A vs Visual Fault Locator

ZS-1000A vs Optical Power Meter

The ZS-1000A effectively incorporates an OPM while providing much more advanced fibre diagnostics.

OTDR vs PON Power Meter

A PON meter and OTDR perform different jobs.

Professional FTTH teams often use several of these tools together.

Using a Launch Cable with an OTDR

For more accurate testing near the OTDR port, technicians should consider using an OTDR launch cable.

A launch cable helps the OTDR analyse the first connector and reduces the effect of the initial dead zone.

Typical setup:

OTDR → Launch Cable → Fibre Under Test

A receive cable can also be installed at the opposite end when end-connector measurement is required.

ZS-1000A Measurement Modes

The ZS-1000A supports:

• Real-time measurement

• Average measurement

• Automatic measurement

Real-Time Mode

Useful when observing changing fibre conditions.

Average Mode

Multiple measurements are averaged to improve the trace quality.

Automatic Mode

Useful when technicians want the instrument to automatically select suitable parameters.

OTDR Pulse Width

The ZS-1000A supports pulse widths from approximately 5ns to 20µs. 

Pulse width affects OTDR testing performance.

Generally:

• Shorter pulses provide better resolution for nearby events.

• Longer pulses provide greater reach but reduce event resolution.

The correct setting depends on the length and complexity of the fibre under test.
