EXFO FTB-1-720-023B OTDR Module 1310/1550nm,35/32dB
IntroductionEXFO'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. Key Features
Dynamic range of up to 36 dB Applications
Access network testing Multimode and Single Mode FlexibilityThe 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. Ordering Information

NOTES
a. All specifications valid at 23 °C ± 2 °C with an FC/PC connector, unless otherwise specified; APC connector for FTB-720 singlemode model.
b. Typical.
c. Typical dynamic range with longest pulse and three-minute averaging at SNR = 1.
d. Multimode dynamic range is specified for 62.5 µm fiber; a 3 dB reduction is seen when testing 50 µm fiber.
e. Typical dead zone for multimode reflectance below –35 dB and singlemode reflectance below –45 dB, using a 5 ns pulse.
f. For multimode port, controlled launch conditions allow 50 µm and 62.5 µm multimode fiber testing.
g. Does not include uncertainty due to fiber index.
h. Typical output power is given at 1300 nm for multimode output and 1550 nm for singlemode output.
i. Under improvement to achieve better conditions.
