OFL280 FlexTester Handheld OTDR with LinkMap

The AFL OFL280-10x FlexTester family offers an unmatched combination of optical fiber test functions, ease-of-use, portability, and value. All OFL280 FlexTester models include an integrated single-mode 1310/1550 nm OTDR with PON-optimized and standard test modes, optical power meter, 1310/1550 nm laser source, and visual fault locator.

With new LinkMap, pass/fail analysis, macro-bend and splitter detection, launch quality check, plus AFL’s unique ServiceSafe and Wave ID features, OFL280 FlexTesters enable even novice users to troubleshoot like pros.

Description

Compatible with AFL Optical Power Meters and

Light Sources

New LinkMap® Simplifies Network Troubleshooting

Using the OFL280’s new LinkMap capability, even novice users can troubleshoot optical networks like a pro! LinkMap interprets the tested network and presents an icon-based

view of network elements clearly identifying fiber start, end, connectors, splices, splitters, and macro-bends. Loss and reflectance of network elements is compared to user-settable pass/fail thresholds and displayed with clear pass/fail indications. Users can instantly toggle between LinkMap and Trace view at the press of a button. With launch quality check, integrated macro-bend and splitter event detection, OFL280 OTDRs offer even greater ease-of-use. OFL280s also provide a Link Summary showing end-to-end link length, loss, loss/distance and ORL.

ServiceSafe® Testing on Live PONs

In FTTx PONs, troubleshooting a faulty fiber connection from one out-of-service subscriber’s location using a 1310/1550 nm OTDR could disrupt service to active subscribers. AFL’s ServiceSafe feature alerts the OTDR user to the presence of live traffic and prevents the initiation of service-disrupting 1310/1550 nm OTDR tests. The OFL280-103 additionally measures downstream power levels at 1490 and/or 1550 nm, and allows the user to initiate an OTDR test using the non-disruptive 1625 nm OTDR wavelength. To eliminate unnecessary connector wear, 1625 nm live PON OTDR testing and PON power measurements are performed through the same optical port used for 1310/1550 OTDR testing (US patent 8,411,259).

Fast, error-free Loss Tests using Wave ID

OFL280s integrate an Optical Laser Source (OLS) and Optical Power Meter (OPM) supporting AFL’s unique Wave ID capability. With Wave ID, the OPM automatically synchronizes to a single or multi-wavelength Wave ID optical signal sent by another OFL280, FLX380, or AFL hand-held OLS. The OPM automatically measures power and loss at each wavelength, saving significant test time and eliminating setup errors.

The integrated OLS and OPM also generate and detect fiber-identifying tones to enable positive fiber identification before disconnecting fibers during maintenance.

Create Professional Test Reports using TRM®2.0

Stored OTDR and/or OPM results may be uploaded to a PC via USB or Bluetooth®. Uploaded results may be viewed and analyzed using TRM 2.0 Test Results Manager software included with each OFL280 FlexTester. The TRM report generation wizard enables users to easily generate professional, custom acceptance test reports conforming to industry guidelines.
