Series of optical reflectometers EXFO MaxTester 720C came to replace the series Max Tester 720B, and the series EXFO MaxTester 730C came to replace the series MaxTester 730B, which was recognized as the best innovative product during exhibitions EEBC 2013 and expoTEL 2013 in Kyiv.
The 720C and 730C Series OTDRs currently in production have slightly improved performance over their predecessors, as well as more combinations of operating wavelengths. At the same time, all the strengths of the previous line are retained: a compact case, a large touch screen, long battery life, a Russified interface thought out to the smallest detail, and, most importantly, high reliability and measurement accuracy ensured in difficult real-life conditions. The appearance of the 720C and 730C series instrument is shown in this photo.
Optical Time Domain Reflectometer (OTDR) Mode
This is the main mode used by the EXFO MAX-720C and EXFO MAX-730C series reflectometers. Depending on the specific models, certain wavelengths are provided. For example, testing singlemode and multimode fibers is only supported by the MAX-720C-Q1-QUAD. And active fiber testing is supported by the MAX-720C-SM2, MAX-730C-SM2, MAX-730C-SM6, MAX-730C-SM7, and MAX-730C-SM8 models.
All models of these series allow you to select the duration of the test pulse in the range from 3 ns to 20 µs. Small pulses provide a minimum dead zone and are well suited for measuring short fibers, while large pulses are designed for long fiber optic trunks where maximum dynamic range is required from the reflectometer.
After measurements are taken, the MAX-720C and MAX-730C Series OTDRs automatically analyze the collected data and generate an event table that lists the range, loss, and reflection for each inhomogeneity found in the fiber (connectors, splices, splitters, macrobends, etc.). The quality of automatic analysis is so high that it completely eliminates all phantom events, reflections from connectors and other artifacts from the trace. And if necessary, you can conduct a manual analysis of any event using the two-point method or the four-point method. To do this, markers are used, the position of which is set by the user.
Advanced Fiber Link Analysis and Schematic View (option iOLM)
Trace display as daisy-chained event blocks (linear display) is a standard feature of the 720C and 730C series. But the iOLM function, which is available as an option, is much more powerful than the linear display mode. iOLM stands for intelligent Optical Link Mapper. When iOLM is running, the OTDR measures one fiber using several different test pulse values and combining all received reflectograms into one detailed scheme.
Using different values of the test pulse allows you to simultaneously obtain small dead zones, allowing you to test the beginning of the fiber in detail, and a large dynamic range, which is necessary for measuring the far end of a long fiber. When the iOLM function is running, in addition to the result in the form of a diagram, the measured reflectogram is also stored in the device's memory, which is convenient for compiling additional reports if they are required. An example of the iOLM option is shown in this screenshot, and a detailed description of this function in Russian is available below on this page in the section Documentation.
Measurement of passive optical PON networks
The MAX-720C and MAX-730C Series OTDRs are well suited for PON networks due to their remarkable performance. The MAX-720C series documentation states that they can measure PON networks with a total division ratio of 1x32, but as shown this is a comparative test, the 720C series does an excellent job even with a total division ratio of 1x64. And the older MAX-730C series easily measures from the subscriber to the OLT station through several splitters with a total division ratio of 1x128.
For measurements of PON network sections during construction, you can use the models of the MAX-720C and MAX-730C series with classic wavelengths of 1310 nm and 1550 nm. But if you plan to serve an already working (active) network, then models with a separate port and a built-in filter are needed. In this case, the working wavelength will be 1625 nm or 1650 nm. As an example, this screenshot shows the trace of a branch of a working PON network, measured from the subscriber's side. The branch contains three splitters with a total split ratio of 1x128. The measurements were carried out using an EXFO MAX-730C-SM8 optical reflectometer.
In this video, you can see the real work of the optical reflectometer model EXFO MAX-730C-SM8 when measuring a passive optical network at wavelengths of 1310 nm and 1550 nm. The tested PON network contains three splitters with a common division factor equal to 1x128. The plot combines the measurements of five different reflectometers. The MAX-730C-SM8 model is shown starting at the 9th minute and 10th second of this video.
Checking the quality of optical connectors
Checking the purity and quality of optical connectors is a mandatory requirement for the operation of modern networks. MAX-720C and MAX-730C series reflectometers have the ability to directly connect optical video microscopes EXFO FIP-400B, which can fully automatically focus, center the image and check the connector for the presence and degree of contamination and defects. At the same time, the reflectometer is used as a means of displaying, processing and storing the obtained photographs.
This figure shows an example of the operation of the EXFO FIP-400B video microscope together with the EXFO MaxTester reflectometer. In the central part of the screen, an optical connector is shown, which, due to contamination, was recognized by the automatic analysis program as non-compliant (unusable). The program marked micro-pollutions with red dots, which in this case served as the reason for such a decision.
Design of optical reflectometers EXFO MaxTester 720C and 730C
The EXFO MaxTester 720C series and EXFO MaxTester 730C series reflectometers are made in a compact case, 166 x 200 x 68 mm in size and weighing 1.5 kg. All optical connectors and other connectors are protected by individual covers, which increases the reliability of the reflectometer and ease of use. The operating temperature at which measurements can be taken is between -10°C and +50°C.
The reflectometers are equipped with a high-quality touch screen with a diagonal of 17.8 cm and a resolution of 800 x 480 pixels. To accommodate the stylus, a separate slot is provided in the instrument case. The battery is located inside the case, its charge is enough for 10-12 hours of full-fledged work. There are no air vents and no cooling fans in the case, which increases reliability and ensures quiet, comfortable operation.

On the top left is an APC polished single-mode port (square with a green border). At the top right is a UPC polished multimode port (square with gray rim). The stylus is on the bottom left.

Options and accessories for optical reflectometers of the EXFO MaxTester 720C and 730C series
The two pictures below show a list of options that can be equipped with the MaxTester 720C and 730C series reflectometers. The first thing to do when placing an order is to select a reflectometer series (MAX-720C or MAX-730C) and a set of wavelengths (SM1, SM2, Q1-QUAD, etc.). Next, you need to select the operating mode: only the reflectometer (option OTDR), only the representation of the fiber line in the form of a diagram (option iOLM) or both modes (option Oi). Next, you need to select the type of polishing of the OTDR input connector: APC corner polishing with reduced reflection (EA option) or UPC regular polishing (EI option). If you need a built-in power meter that is compatible with the OTDR port for active fiber measurements, then add the OPM or OPM2 option. Further, you can add advanced functionality of the iOLM mode (options iADV,
You can also add an integrated power meter (Option PM2X) or an integrated power meter and VFL illumination (Option VPM2X). The built-in power meter connector type is determined by the FOA option. Option FR2 is a measurement post-processing program with many automation functions. When ordering the RF option, the reflectometer comes with built-in WiFi and Bluetooth. Next come the optical video microscope options FIP-400B, which can be connected directly to the USB port of the reflectometer, and attachments to it. See the full list of options and accessories for the EXFO MaxTester 720C and EXFO MaxTester 730C optical reflectometers below on this page in the section Documentation.
