Short Dead Zones

EXFO’s FTB-720 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 distribution panel. This feature also comes in handy in access and LAN/WAN network applications, where events are usually closely spaced.

Multimode and Singlemode Flexibility

The FTB-720 model combines singlemode and multimode functionalities, ideal for private/premises/enterprise network testing. It offers the industry’s shortest dead zones, as well as lightning-fast acquisitions. Test multimode fiber within premises or singlemode fiber between premises—all with a single OTDR unit—and maximize your return on investment.

Filtered Port for Live Fiber Testing (Singlemode only)

The singlemode model now features a filtered 1625 nm port for in-service troubleshooting of live networks, such as P2P, FTTx and PON. The singlemode model is a versatile day-to-day tester for any access networks.

Pulse Selection vs. Dead Zone

Application Notes

Generally speaking, the rationale behind selecting the shortest pulse on an OTDR is to obtain the best spatial resolution, and the best event and attenuation dead zones needed to detect and measure very closely spaced events.

OTDRs are often used with a launch fiber/cable, and may also use a receive fiber/cable. The launch cable, aka “pulse suppressor” or “dummy fiber,” allows the OTDR to recover after the test pulse is sent into the fiber. This cable provides an invaluable reference on the first connector of the cable under test for determining its loss and reflectance.

Everyone agrees that fiber inspection is critical, though it is still considered a complex and time consuming test process. See how EXFO is changing the game with the FIP-430B, its fully automated fiber inspection probe turning fiber inspection into a quick and simple one-step process.

The intent of this application note is to promote a better understanding of video inspection probe specifications and features. Properly understanding the key specifications and features will greatly facilitate the decision process involved in acquiring such devices. Understanding the key aspects of fiber inspection probes will also help users understand how fiber inspection probes operate, thus enabling them to maximize the full potential of these devices.
