PON Subscriber Bandwidth Share Calculator

Estimate an equal-share downstream and upstream rate per subscriber for a shared PON port under full load and a user-entered concurrency assumption.

Inputs

Link inputs

Range: 1–100,000 Mbps

Enter net service capacity available to subscribers, not nominal physical line rate.

Range: 1–100,000 Mbps

Enter net service capacity available to subscribers, not nominal physical line rate.

Range: 1–512

Count subscribed ONUs on this PON port.

Range: 1–100 %

Enter a planning assumption for the share simultaneously drawing capacity; this is not a protocol guarantee.

Result

Downstream equal share at entered concurrency (Mbps)
500.00
Downstream per subscriber at full simultaneous load (Mbps)
125.00
Estimated concurrent subscribers
16.0
Upstream equal share at entered concurrency (Mbps)
500.00
Upstream per subscriber at full simultaneous load (Mbps)
125.00
