GPON - Switch SFP directly to ONT, without OLT

I know that in a GPON network, multiple ONTs are connected through optical splitters to an OLT.

However, is it possible to connect an Ethernet switch SFP port directly to an ONT, without using an OLT or any spiltters? One ONT per SFP?

To be precise:

Ruckus ICX7450-48GF switch ( specs ) -- SFP ( specs ) -- Fiber -- Alcatel-Lucent G-010G-A ONT ( specs )

I know it's an unusual design. I'm just wondering if it could work, or if the ONT will only connect to an OLT.

Thanks!
