Default Optical fiber - laser Vs Diod noise

Hi,

I have an optical bridge for network noise isolation from 4 years, based on a delock 86443 ethernet/optical media converter supplied (donwstream) by lifepo4 battery (this MFC does not have inner HF voltage regulator and is great with a battery supply).

I have a huge and great impact on the SQ with it in half duplex optical mode / lowest 10Mbs ethernet rate.

I need to connect this downstream delock to a new router with an SFP (optical) slot.

The Delock 100base FX MM 1310nm spécification and i don't find any SFP on this specs for my router (ubiquiti edge router X SFP).

I will probably change the delock it for a Gb one.

I have the choice between SX monomode and multi mode.

Monomode is laser diod, Multi mode is diod. I cannot test each all kind of SFP.
Considering the Laser/diod noise has a strong effect on noise (i can see it using half duplex Vs full duplex), do you know wich one might produce the less noise ?

Thank you

B.
