How many EPON ONU can your EPON OLT connect?

  The connected EPON ONU quantity depend on the EPON OLT PON ports quantity and splitter ratio.

  For example, 4PON port EPON OLT can connect 128pcs EPON ONU in 1:32 splitter ratio; If in 1:64 ratio, it can manage 256pcs EPON ONU. 

What splitter ratio should I use in your EPON OLT/ONU network? Can I use 1:64 splitter ratio?

  Whether EPON ONU can receive signal from EPON OLT is effected by factors such as transmission distance, splitter structure level, cable and connector loss, etc.

  So, to guarantee the subscriber bandwidth and network stability, we recommend 1:32 ratio in your EPON network within 20Km.

  If your EPON network distance is short, splitter level and transmission loss is small, you can also try 1:64 ratio. 

Can I buy ONU module only?
