The SAT-18B is designed as singlemode configuration.It can be used for testing on double wavelength. User can choose combination of 1310 and 1550nm wavelengths to covering all fiber applications from Telenet and WDM to MAN, FTTH and LAN network.It provide a stable light source, as well as the option of adding a visual fault locator.
All the OTDR Modes You Need
The SAT-18B’s OTDR software is both automated and easy to use，Choose from two operating modes according to your specific requirements:
Auto Mode
Lets you select acquisition parameters automaticlly.Perfect for basic, repetitive OTDR applications or for occasional users.
Manual Mode
Multiple setup and measurement capablities increased flexibility.Control all parameters on a single page and optimize your measurement setup to pinpoint specific anomalies.
Ideal for access and FTTH network testing, let you characterize all events between the transmitter and the central offic’s fiber distribution panel.
SAT-18B configration delivers twice-wavelength testing with a choice of wavelengths ：1310/1550nm。
Test through high-port-count splotters-even 1×32
1.6m event dead zone: Industry-leading
Attenuation dead zone starting at 4.5m
Four-time-shorter testing time，for minimized testing costs
Market-leading linearity of ±0.03dB/dB，for highly accurate event characterization
Dynamic range of up to 35dB
Speciality Report
Make use of configurable report and batch printing, fast and effectively create full speciality report.
Export as SB Standard Binary
Saving OTDR record and loading OTDR results as SB Standard Binary.
Optical Fiber Cable Report
Creat optical fiber cable report and get particular report:
1. Fiber event- report Display full event-data in compact foramt
2. Fiber zone-report Scrutiny all fiber-in-the-zona
3. Fault report Base on fault feedback of user-threshold
Batch printing
You can choose three print-mode：standerd mode（full-size, multipage OTDR report）, compress mode（one page report）and more curves（four、six、or eight curves on one page）. In addition , add event statistical report.
Fast print
Print the OTDR cruve of display and choose stat..
