Four-Wavelength OTDR
Jan 2005
EXFO Inc.Request Info
QUEBEC CITY, Jan. 28 -- Exfo Electro-Optical Engineering Inc. has introduced its FTB-7200D four-wavelength optical time domain reflectometer (OTDR) for the premises network and cabling installation markets.

This unique OTDR, a single-slot module housed in either the FTB-400 or FTB-100B field-testing platforms, characterizes both multimode and singlemode fiber on as many as four wavelengths. It boasts the shortest dead zones in the industry: event dead zone of =1 m and attenuation dead zone of =4.5 m (3 m at 850 nm) for both multimode and singlemode fiber. In addition, it offers a high dynamic range: 26 dB at 850 nm, 25 dB at 1300 nm, 35 dB at 1310 nm and 34 dB at 1550 nm.

EXFO’s Four-Wavelength OTDR is suitable for fiber optic contractors and private network operators. On the strength of industry-leading specifications, it enables them to fully test and qualify any type of fiber network. Its intuitive graphical user interface (GUI) and extensive software capabilities allow users to efficiently post-process test results and create professional test reports—all of this with very limited training.
