What "port count" actually means for subscriber capacity
Each OLT port feeds a splitter, which divides that one fibre connection across multiple subscribers. An OLT's real subscriber capacity is port count multiplied by your chosen splitter ratio, not the port count alone.
Splitter ratios explained
| Ratio | Subscribers per port | Trade-off |
|---|---|---|
| 1:8 | 8 | Lower subscriber count per port, higher per-subscriber bandwidth headroom |
| 1:16 | 16 | Balanced choice for many small-to-mid deployments |
| 1:32 | 32 | Higher subscriber density, more bandwidth sharing per port |
| 1:64 | 64 | Maximum density, most bandwidth sharing, needs careful capacity planning |
Standalone vs chassis-based OLTs
A standalone OLT is a fixed-port, lower-complexity unit, a sensible starting point for a first deployment. A chassis-based OLT accepts modular line cards, letting you add capacity as you grow rather than replacing the whole unit, worth the extra planning for an operator confident about scaling past their first site.
Software and management considerations
Some OLT platforms carry ongoing management or licensing considerations beyond the hardware purchase. Confirm this directly with your supplier before committing, since it affects total cost of ownership over the OLT's life, not just day one.
Questions to ask a supplier before you buy
- What's the real subscriber capacity at the splitter ratio I'm planning to use?
- Is this standalone or chassis-based, and does that match my growth plan?
- Are there ongoing licensing or management costs beyond the hardware?
- What ONU/ONT models is this OLT confirmed compatible with?
