Emulating rogue optical network unit behavior in a passive optical network
A device can include a first component to receive, from a first network device, a first upstream optical signal. The first upstream optical signal can be associated with a designated time slot of the first network device. The device can include a second component to receive, from the first component, the first upstream optical signal. The second component can split the first upstream optical signal into a second upstream optical signal and a third upstream optical signal. The second component can provide, to a second network device, the third upstream optical signal. The third upstream optical signal is not associated with the designated time slot of the first network device.
