OTDR Technology for Accurate Fibre Fault Detection

The main function of the JW6601A is Optical Time Domain Reflectometry, a technology used to investigate the condition of optical fibre cables.

An OTDR sends controlled light pulses into an optical fibre and analyses the returning light. This allows technicians to estimate distances to reflective events, evaluate fibre attenuation, and locate potential faults along a connection.

The JW6601A is useful for identifying problems such as:

• Broken or damaged fibre cables.

• Excessive attenuation along fibre links.

• Poorly performing splice locations.

• Reflective connector events.

• Unexpected signal losses.

• Fibre link termination points.

• Abnormalities introduced during installation or maintenance.

Instead of relying entirely on manual inspection, technicians can use OTDR measurements to narrow down the location of a suspected problem.

This is particularly valuable when maintaining long fibre routes, underground fibre infrastructure, building-to-building links, or distribution networks where direct physical inspection may be difficult.

The JW6601A helps locate and analyse fibre faults, but it does not repair damaged fibre or replace a fibre fusion splicing machine.

OTDR Performance and Measurement Capabilities

The Joinwit JW6601A is designed to balance measurement performance with portability for routine fibre network work.

The standard dual-wavelength model is commonly specified with the following OTDR characteristics:

These figures describe published JW6601A configurations. The exact supplied version should be confirmed before purchase.

Understanding the Dynamic Range

The 28/26 dB dynamic range allows the OTDR to analyse attenuation and reflected signals across suitable fibre links.

Dynamic range is important because it influences how effectively an OTDR can measure optical events when signal levels become weaker along a fibre route.

However, an 80 km selectable measurement range does not guarantee that every 80 km fibre link can be tested successfully. Actual performance depends on total link loss, reflectance, splitter losses, pulse width, and other network conditions.

Event and Attenuation Dead Zones

The JW6601A has a published event dead zone of 3 metres and an attenuation dead zone of 8 metres.

These specifications help technicians understand the instrument's ability to distinguish events occurring close together.

For projects involving very closely spaced connectors or short fibre sections, technicians should consider the instrument's dead-zone limitations and use an appropriate launch fibre where required.

Optical Power Meter for Fibre Signal Measurement

The JW6601A includes an Optical Power Meter function, allowing technicians to measure optical signal power during fibre installation and maintenance.

This is useful when checking whether optical signals are present and assessing signal levels against the requirements of connected equipment.

Published specifications for the standard optical power meter include:

• Measurement wavelength range: 800–1700 nm.

• Calibration wavelengths: 850, 980, 1300, 1310, 1490, 1550, 1625, and 1650 nm.

• Optical power measurement range: -50 dBm to +26 dBm.

• Published measurement uncertainty: ±5%.

The optical power meter is particularly valuable when technicians need to check fibre links after installation, investigate low received power, or verify signal levels during network maintenance.

Unlike the OTDR function, which analyses events along a fibre, the optical power meter measures optical power at the connection point.

Important: A standard optical power meter does not automatically replace a dedicated PON power meter for simultaneous wavelength-selective measurements or upstream burst measurements. The JW6601A also has a separately specified 10G optical power meter function, whose availability should be confirmed for the supplied version.

Visual Fault Locator for Quick Fibre Troubleshooting

The integrated Visual Fault Locator (VFL) provides another useful function for technicians working with fibre optic cables.

A VFL sends visible red laser light through compatible optical fibre, helping technicians identify faults where escaping light can be observed.

The JW6601A VFL is documented with a nominal wavelength of 650 nm and an output power of at least 10 mW.

This function is useful for:

• Identifying faults in accessible fibre sections.

• Checking short fibre patch cords.

• Detecting visible leakage at severe bends or damaged points.

• Verifying continuity in suitable fibre connections.

• Assisting with fibre identification during maintenance.

The VFL can be particularly convenient when working with fibre distribution boxes, patch panels, and short connection cables.

However, a VFL cannot replace OTDR testing when technicians need to measure the distance to a hidden fault or analyse losses along a long optical fibre route.

Never look directly into the VFL output or the end of a connected fibre.

Optical Light Source and Optical Loss Testing

The JW6601A also incorporates an Optical Light Source function, supporting optical transmission and loss measurements when paired with a compatible optical power meter.

Published light source specifications include:

• Output wavelengths: 1310/1550 nm for the documented standard configuration.

• Output power: at least -5 dBm.

• Modulation options: continuous wave, 270 Hz, 1 kHz, and 2 kHz.

• Output stability: ±0.5 dB over 15 minutes under the specified test conditions.

Technicians can use a suitable light source and power meter arrangement to measure end-to-end optical loss.

This is useful when checking fibre links after installation, performing commissioning tests, or investigating connection quality.

The optical loss test complements OTDR measurements because the two methods provide different information about fibre performance.

For reliable acceptance testing, installers should follow the required measurement procedure, reference method, and applicable project specifications.

RJ45 Network Cable Testing Functions

In addition to optical fibre diagnostics, the JW6601A series includes RJ45 cable testing functions.

Documented capabilities include cable tracking and cable length testing, with published ranges of up to approximately 300 metres for the relevant functions.

These features are useful for technicians who install both fibre optic connections and Ethernet cabling.

For example, a technician working on an FTTH installation may need to troubleshoot the fibre connection and inspect the Ethernet cabling linking networking equipment.

Having both optical and RJ45 diagnostic functions in one instrument provides additional convenience during site visits.

However, RJ45 tracking and length testing should not be confused with full structured cabling certification. The JW6601A is not a replacement for a dedicated copper cable certification tester where certified Cat6 or Cat6A performance measurements are required.

Colour Touchscreen and Test Result Management

The JW6601A features a 4.3-inch colour touchscreen designed to make fibre testing and measurement review convenient during fieldwork.

Technicians can use the display to navigate supported testing functions, view OTDR results, and inspect detected fibre events.

The instrument supports automatic OTDR operation as well as more detailed testing modes for technicians who need greater control over measurement settings.

Its event map functionality simplifies the presentation of detected events, helping users identify areas that require closer inspection.

The JW6601A also supports standard SOR trace files, allowing saved OTDR results to be reviewed using compatible software.

This makes the tester useful for contractors who need to retain fibre testing records, document installation results, or provide measurements as part of project handover.

Rechargeable Battery and Portable Field Operation

The JW6601A is designed for technicians who frequently move between installation sites.

Its compact construction allows it to be carried to residential properties, commercial buildings, telecommunications cabinets, and other field locations.

Published power specifications include a 3.7 V, 4000 mAh rechargeable lithium polymer battery and 5 V DC charging.

Manufacturer-associated product documentation lists a measurement operating time exceeding 12 hours under stated conditions. Actual battery performance can vary depending on the functions used, screen settings, battery condition, and operating environment.

USB charging adds convenience for technicians working away from fixed workshop facilities.

The portable design is especially beneficial for ISP support teams responding to fibre faults across multiple customer locations.
