Does a fiber optic splitter need a power supply
Optical splitters are passive devices that split a single optical signal into multiple signals or combine multiple signals into a single one. The. Light power goes in and light power coming out of the various legs is reduced in accordance to the split ratio. For every 2X increase in split ratio, power is reduced by roughly 3 dB. “Passive” means it needs no electricity. Each output carries a portion of the original light's power.
