When purchasing a fiber optic OTDR, the price depends on various factors, such as functionality, precision, and application. Here are the most common OTDRs, ranging from simple to complex, and their various prices.
Standard OTDRs
A standard OTDR is commonly used to test fibre optic networks in the telecommunications industry. Such OTDRs can effectively map large networks and locate faults. These standard OTDRs are priced moderately, depending on the brand and quality, ranging from 1000 to 2000 dollars.
Singlemode OTDRs
Singlemode OTDRs are intended for long-distance communications through singlemode fibre. Thanks to their powerful test capabilities, these devices are effective for long-distance fibre cabling, mainly used in telecommunication companies. The prices of these OTDRs are from 2,000 to 5,000 dollars.
Multipulse OTDRs
Multipulse OTDRs send various pulse lengths to examine fibres with different attenuation rates. Multipulse OTDRs are valuable in characterising long or complex fibres. Because of this functionality, these OTDRs are significantly more expensive than standard ones and usually range from 5,000 to 12,000 dollars.
Handheld OTDRs
Users operating in the field prefer handheld OTDRs because they are portable and easy to use. These OTDRs are designed for quick testing and troubleshooting. They are lightweight, and their prices range from 1,000 to 3,000 dollars.
Laboratory OTDRs
Laboratory OTDRs are accurate and highly sensitive instruments characterising fibres in a lab setting. They provide minute detail and precision analysis. Such OTDRs are significantly expensive and can range from 10,000 dollars to 30,000 dollars.
OTDRs of various categories are applied in the maintenance and testing of fibre optic cables. Here are the qualities that equip the OTDRs to function effectively as required.
Measuring Functions
OTDR can measure the length of the cable and optical loss. These parameters provide users with the overall network status. Finding cable length helps avoid any misconfiguration, while the loss of optics indicates the need for signal trouble.
Dynamic Range
Dynamic range means detectable reflector of different strengths or reflection. It tremendously impacts the distance over which the device can operate: the greater the dynamic range, the larger distance OTDR can be used. A typical function of the device for standard cables is about 20dB, while a long-range fibre cable might need up to 30 dB.
Pulse Width
OTDRs send short pulses of light into fibre to measure backscattered light. This means that the pulse width determines how much resolution is targeted by OTDR. Shorter pulse widths mean better resolution. Several OTDR operating pulses are in the range of 0.5 μs to 10 μs.
Distance Accuracy
Distance accuracy is the overall length of fibre that can possibly be measured accurately by the OTDR. OTDR cited for distance accuracy should be precise for long runs of fibre, vital for large infrastructure networks. Distance accuracy is typically a few per cent of the total length of fibre.
Connectorisation Threshold
The connectorisation threshold is the minimum loss that an OTDR can detect across a fibre connection. Such thresholds mean that small losses in cable connectors and splices could go unnoticed. An effective OTDR should show loss of at least 0.1 dB.
Fibre Characterisation
Fibre characterisation involves the capability of OTDR to depict various and accurate data on the type of fibre being used. Such information includes core size, attenuation, and refractive index. These characteristics help determine whether a network is performing at its best. For a fibre characterisation function, an effective OTDR should provide accurate and precise information to the user.
Accurate Network Testing
OTDR performs tests on long-distance fibre optic networks, localising faults and measuring signal attenuation over great lengths. Such characteristics make it an important tool for telecommunication. Accurate testing is instrumental in reducing the overall operational costs by pinpointing issues quickly and limiting downtime.
Increased Installation Efficiency
OTDR allows for systematic and efficient identification of installation issues during and after fibre network installation. Technicians can detect potential problems before they affect performance. Therefore, this minimises the need for rework and consequently realizes significant savings both in time and costs.
Long-Term Cost Savings
Though there is a significant up-front cost with OTDR, in the long run, it pays off. Detecting problems early helps to save money. Accurate testing means fewer expensive service calls in the future, hence saving time and money in overall maintenance costs.
Value for Preventive Maintenance
Telecommunications companies use OTDR for regular network checks and preventive maintenance. Regularly identifying potential fibre issues before they become critical problems prevents network outages. Staying ahead of the problems ensures that users never face performance degradation. It enhances customer satisfaction and protects the company's reputation.
Reduced Downtime
OTDR marks or localises network faults in real time, assisting fibre optic repair with minimal network downtime. The quick pinpointing of problems reduces the total business impact, especially for those dependent on constant network availability. It enables companies to quickly bring services back online, limiting interruptions to their operations and consequently enhancing overall commercial value.
Application requirements
The most important factor is the intended application. An OTDR for telecommunication networks must handle long distances and high dynamic ranges. An OTDR for indoor or short-exposure networks may not require such capabilities. Knowing the purpose helps select the right device.
Singlemode and Multimode Capabilities
Optical time domain reflectometers are available in singlemode and multimode fibres. If working predominantly with singlemode fibres, an OTDR rated for singlemode is needed. For networks that use multimode fibre, an OTDR multimode will be more appropriate. Choosing the device that fits the fibre type used will ensure optimum performance and accurate testing.
Pulse Width and Dynamic Range
These two parameters are vital because they determine the resolution and distance the device can measure. Short pulse widths offer high resolution, while a large dynamic range means that it can effectively measure both short and long-range fibres. Therefore, selecting the OTDR with the pulse width and dynamic range appropriate for the application is key to achieving accurate measurements.
Budget considerations
OTDR prices vary widely, depending on their specifications and features. Often, high-end models cost more, but sometimes the features are not necessary for basic applications. It is advisable to balance the budget with the operational needs. Selecting the one that provides best value rather than getting the most expensive one will still yield great results.
Portability and ease of use
OTDR intended for fieldwork should be portable and easy to use. It should fit the technician's working style. Features like a touch screen, easy navigation menus, and rugged designs suitable for outdoor use are very important for operational efficiency.
Technical Support and Warranty
Fibre optic testers in the telecom industry might require technical support in case of a problem. It is therefore crucial to investigate whether the manufacturer offers superior customer support and warranty coverage. A warranty extension may cover costly repairs or device replacement, thus providing peace of mind and long-term affordability.
OTDR sends pulses of light down a fibre optic cable and measures the amount of light that scatters. Then, by examining the scattered light, it creates a detailed map of the cable, showing lengths, losses, and any faults or breaks. In simple terms, OTDR is like a super smart flashlight that helps people find out how their fibre optic cables are working over long distances.
The average price of OTDRs ranges from about 1,000 to 5,000 dollars for most people. Some more advanced models, which offer longer and more complicated work, can cost as much as 30,000 dollars.
Abenchtop is generally better than handheld OTDRs in performance and features. Handheld OTDRs are portable and convenient, making them great for fieldwork, especially in outside work. They are small and easy to carry. A benchtop OTDR is larger, stronger, and most often fixed in one place. They provide more detailed test results and are used in the laboratory for long hours of work.
Yes, OTDRs can work on multimode fibre. There are special OTDRs designed just for multimode fibre. They send light through the fibre and give a detailed report on how the fibre is working. This helps people find any problems fast.
The three main parts of an OTDR are the light source, the main unit, and the screen. The light source sends a pulse of light into the fibre optic cable to do the work. The main unit does all the thinking and calculations. The screen shows the results.
