The EXFO™ FTB-720-12CD-23B-OTDR-91-AD OTDR Module
is an accessory module that can be used in conjunction with the 850/1300/1310/1550nm wavelengths to take on FTTX/MDU test challenges within PON networks for both multimode and singlemode installations. It features an event dead zone of 0.8m, a dynamic range of up to 35 dB APC/SC connector and auto diagnostic software for macro bend detection, P/F & fault finder testing. The device measures based on a user-defined interval time, with a real-time refresh rate of 3 Hz, and stable source output power of -2.5 dBm and reflectance of +/- 2. Additionally the module has a PON dead zone of 35 and a loss threshold of 0.01 to 0.001 dB and a sampling resolution between 0.04 to 5. The FTB-720 is capable of sampling up to 256,000 points at one time.
The EXFO™ FTB-720 Quad OTDR module contains the module itself.
