How to calculate the optical attenuation value of the optical splitter?

Optical attenuation value of the optical splitter = transmitted optical power + additional loss + insertion loss + bare fiber loss.

1. Calculate the splitting ratio

Formula: ki = Pi / SP * 100%

Pi ：The driving power required for each optical link.

SP：The sum of the required driving powers of each optical link carried by the laser.

The PLC Fiber Optical Splitters produced by SoctFiber will indicate the splitting ratio, this depends on the customer's project requirements，such as 1 to 2 is 80%:20% ; 1 to 3 is 70%:15%:15%; 1 to 4 is 70%:10%:10%:10%.

Note: The optical performance of the Fiber Optical Splitters does not include connector loss and adapter loss

Typical Insertion Loss Value of Optical Splitters (Uniform Splitting):

2. Additional Loss Calculation

In practical operations, additional loss values can be measured and assessed as needed. It only needs to detect and record the value according to certain operating specifications, and classify different links.

The loss of a general 1×N single-mode standard splitter is as follows:

3. Insertion loss calculation

Formula: IL＝-10lg(Po/Pi)

Po: the optical power at the output end.

Pi: the optical power at the input end.

Note: In the formula, Po/Pi is equivalent to the splitting ratio of the splitter, that is: IL＝-10lg(ki). For example, there is a one-to-two splitter, which is a 28 split, that is, the splitting ratio is 20%:80%. The theoretical insertion loss of its 20% split link is -10lg(20%), which is approximately equal to 6.99dB.

Reference Values for Secondary Splitter Output Loss under Various Split Ratios:

4. Bare fiber loss calculation

In practical operation, manual calculation of this value is unnecessary, as a defined reference standard is available. By adhering strictly to the numerical standard, loss values at different wavelengths can be measured to determine the final loss value.

When the optical signal is transmitted through the optical splitter, its loss value has nothing to do with the transmission direction. Whether the optical signal is transmitted from the input end of the optical splitter to the output end, or from the output end to the input end, the loss value is the same in both transmission directions. Therefore, we only need to measure the loss value of the optical splitter in one direction.
