The Micro OTDR is the perfect tool for the construction and maintenance single and multi mode optical fibers. It measures and displays the attenuation in optical fibers and splices, as well as the length and the distance to any event, such as a break in fiber link all can be stored and printed. This high quality Micro OTDR is accurate enough for laboratory use but portable and rugged enough for field applications. Read more about it in this version of the AFS Newsletter!

 

Micro OTDR's

 

Multimode and Single mode

 
The included powerful software ties together all the different cable criteria that are found and shows the user a clear picture of it. The user friendly applications can be controlled easily by every field technician. Read in the following part for what reasons the OTDR's are used in conjunction with a Laptop or PC with a USB interface:
 
- The software allows the user to determine all the necessary characteristics of the Optical Fiber and is capable of displaying, storing, reading, printing and analyzing several traces simultaneously.
- The unit is powered via the Laptop USB port and requires no batteries or external power supply.
- The USB connection allows the instrument to be controlled from a laptop and runs off of Windows 98 or more recent.
- The OTDR has never a full memory, because all data will be saved on the laptop. The trace storage is unlimited in contrast to other manufacturers.

High quality OTDR's, advanced features

 
AFS offers five models of Micro OTDR's. They all have various features, but there are also features who goes for all OTDR's, that is the subject of the following part.
These features applies for all AFS Micro OTDR's:
- A distance range up to 240 kilometers.
- Refractive Index Range Setting 1.0000 to 2.0000.
- Loss Resolution of only 0.001 dB.
- Supply current from USB port <200mA.
- Low distance accuracy.
- Event dead zone 3.5 meters.
- Handheld, lightweight and easy to use.
- No defect buttons or screen, because this OTDR controlled completely from a Laptop.
 
 
 

Different implementations, different specifications

 
As given above, there are five different Micro OTDR's. One multimode and four single mode versions with different specifications, they are all explained in the tabular overview below. The dynamic range is the feature which distinguish the SM OTDR'S of each other. Take a look at the advanced features of the uOR-100 series and uOR-200 series!
