OTDRs and Fault Locators

NOYES® optical time domain reflectometers (OTDRs) and fault locators from AFL are used to certify new fiber installations and locate faults in deployed fiber optic networks. OTDRs and fault locators are available for both multimode and single-mode networks, including FTTx PONs. OTDRs scan fiber optic networks from one end of the fiber, displaying a trace and reporting detected events such as splices, connectors, micro- or macro-bends and fiber end. Fiber length is reported along with location, loss and reflectance of detected events. Several OTDRs are available with an integrated visual fault locator (VFL), optical light source (OLS), and/or optical power meter (OPM). OTDR results can be saved and uploaded to PC for further analysis and/or archiving.

The OFL280-103 with ServiceSafe™ can fault-locate live fibers without disrupting service, and includes PON Power Meter to measure downstream FTTx power levels.
FlexTester Complete and Complete2 kits bundle all the test and inspection equipment required by installation and maintenance technicians to complete optical network verification and troubleshooting. Kits are packaged in a convenient, rugged, lightweight carry case. Bundled kit price provides significant cost savings compared to purchasing all included items individually.
NOYES FlexTester PRO / PRO2 Kits combine either a FLX380 or OFL280 FlexTester with either a FOCIS PRO or FOCIS Flex Fiber Optic Connector Inspection System and connector cleaning supplies. Designed for optical network installers, FlexTester PRO / PRO2 Kits are packaged in a rugged, waterproof, lightweight hard carry case.
M700 / M710 large screen OTDR models can test networks up to 280km long. These units are simple to use and feature rich with TruEvent technology - providing accurate, dependable results. These hand-held units are ready for most field test needs, ranging from long haul to enterprise networks. The combination of industry leading event analysis and high dynamic range make the M7x0 units the right tool for all of your fiber network testing needs.
The C850 is a compact multimode and single-mode OTDR with integrated OPM, OLS, and VFL. The C850 is designed for testing, troubleshooting & documenting Enterprise fiber networks. Touch and Test® an intuitive visual user interface simplifies the user experience, reduces training time & testing errors enabling novices to get the job done accurately. Comes with TRM™ reporting software for reports compliant to TIA/ISO guidelines.
The C860 is the most efficient single-mode and multimode fiber optic certification OTDR (Tier 2) and loss (Tier 1) test set. Bi-directionally certify two fibers in two directions. Integrated OTDR, OPM, OLS and VFL allow users to complete more tests and generate comprehensive acceptance reports quickly. Touch and Test® user interface has pass/fail thresholds and auto-test modes to enable technicians to test like a fiber expert.
The NOYES OFL250 is a single-mode OTDR with an integrated optical power meter (OPM), optical laser source (OLS), and visual fault locator (VFL) in a hand-held package weighing only 0.8 kg (1.8 lb). With short dead zone and 26 dB dynamic range, the OFL250 is ideal for troubleshooting single-mode fibers in local access and metro area networks.
The NOYES FTK Pro Installer Kit from AFL is an all-in-one fiber optic test equipment kit. The FTK kit provides a wide selection of fiber optic testing, cleaning, and inspection equipment to enable technicians to install and maintain fiber optic networks. Complete with multimode and single-mode test equipment, the kit includes cleaning and inspection equipment in a tough transit case. The Pro Installer Kit is ideal for TIA Tier 1 and Tier 2 testing and troubleshooting of enterprise networks.
NOYES Fiber Rings from AFL are often a necessity when testing with an OTDR. Both a launch and receive cable are required to measure complete link loss of a fiber with an OTDR. Because very long test cables are impractical to transport and use, NOYES designed coiled lengths of 50 µm multimode, 62.5 µm multimode, or single-mode fiber conveniently packaged in compact rings.
Test Results Manager TRM® 2.0 is a powerful all-in-one Analysis and Reporting tool designed for use with AFL fiber optic test and inspection products. Users can review OTDR, OLTS, Certification and Connector Inspection results, analyze results and apply pass/fail criteria to Loss and OTDR results. Customized acceptance reports can be created by selecting from templates for presentation of results to end users for job signoff.
