How to well understand performance of a FBT fiber splitter and PLC optic splitters? The first important thing is to discover its Fiber Optic Splitter Insertion Loss Table. This is the basic parameters should be archived. This Fiber Optic Splitter Insertion Loss is the splitter devices loss, Considering fiber connectors or connectors+adapter insertion loss in LGX, The fiber splitter IL would be a little bigger.
Brief Introduction to Optical Splitters
Optical insertion loss
The optical splitter is the component with the largest attenuation in a PON system. The optical insertion loss is the loss of an optical signal resulting from the insertion of a component such as connector or splice in an optical fiber system. In order to conserve the power budget of a PON system, the insertion loss from the splitter needs to be minimized.
How to calculate the maximum allowable insertion
The maximum allowable insertion loss for an optical splitter used in a PON system can be determined by using the calculations outlined in the below table.
|The maximum allowable insertion loss|
|1×N Optical Splitter||0.8 + 3.4 log2N|
|2×N Optical Splitter||1.0 + 3.4 log2N|
|Note: ‘N’ denotes the number of output ports.|
Temperature Dependent Loss
In certain areas, temperature can be a crucial factor that affects the insertion loss of optical components. FBT splitter can work stable under the temperature of -5 to 75℃. PLC splitter can work at a wider temperature range of -40 to 85 ℃, providing relatively good performance in the areas of extreme climate.
