All-Fiber OTDR 850/1300nm, 24/25 dB, 1310/1550nm, 32/30 dB
Product DescriptionAll-Fiber OTDR
Combining singlemode and multimode capabilities for enterprise, campus and access networks, this model offers the 850, 1300, 1310 and 1550 nm wavelengths, with respective dynamic ranges of 24, 25, 32 and 30 dB.
Applications
Easy Location and Characterization of Events
EXFO's AXS-110 All-Fiber OTDR helps you boost test productivity for inside-plant applications. Its exceptional 0.8 m event dead zone enables you to easily locate and characterize all events between the transmitter and the central office’s fiber, access and FTTH network applications, where events are usually closely spaced.
Multimode and Singlemode Flexibility
The AXS-110 combines singlemode and multimode functionalities, ideal for premises, private and enterprise network testing. Test multimode fiber within premises, or single-mode fiber between premises—all with a single OTDR unit—and maximize your return on investment.
End-to-End PON Characterization
The AXS-110 lets you test through high-port-count splitters—even 1 x 64 splitters—perfect for passive optical network (PON) testing, delivering these key advantages:
Perfect tool for FTTx contractors and tier-2 certification of premises networks
Pass/fail features that comply with industry standards such as TIA 568c and IEEE 802.3ah
Highest dynamic range of the industry for a handheld OTDR
Power meter option, for crosschecking the total loss using the built-in OTDR laser in continuous source mode
