If you are setting up or expanding a fiber broadband network in India, one of the first decisions you will face is choosing between a 4 port and 8 port EPON OLT. Both do the same job; they connect your fiber subscribers to your network but they suit different situations. Here is a simple breakdown to help you decide.
What is an EPON OLT and Why Does Port Count Matter?
An EPON OLT is the central device in your FTTH network that manages fiber connections from your end to the subscriber’s ONT/ONU device at home. Each PON port on the OLT can handle multiple subscribers — typically 32 to 64 ONUs per port depending on your split ratio.
So when you are choosing between 4 port and 8 port, you are really choosing how many subscribers your OLT can handle at full capacity.
4 Port EPON OLT — Who Should Buy It?
A 4 port EPON OLT is a good starting point for small ISPs, local cable operators, or housing societies just beginning their fiber rollout. With a 1:64 split ratio, a single 4 port OLT can support up to 256 subscribers, which is more than enough for most small deployments.
The Adopt AD1E-0444 4 Port Layer3 EPON OLT is a solid choice here — compact 1U rackmount design, 64Gbps switching capacity, 10GE SFP+ uplinks and 3-year warranty at ₹22,525. It covers everything a small to mid-size ISP needs without overspending on ports you may not use for months.
Buy 4 Port if:
- You have under 200 active subscribers right now
- You are just starting fiber rollout in a new area
- Budget is a priority and you want to test the market first
8 Port EPON OLT — Who Should Buy It?
An 8 port EPON OLT doubles your capacity — supporting up to 512 subscribers across 8 PON ports. This makes sense when you already have a healthy subscriber base and are expanding fast, or when you want to cover multiple buildings or areas from a single OLT without adding another device.
The Adopt AD1E-0844 8 Port Layer3 EPON OLT comes with dual power supply, same Layer 3 management features and is available at ₹48,000 — roughly double the price of the 4 port model, but you get double the capacity and better redundancy with dual power.
Buy 8 Port if:
- You have 250+ active or planned subscribers
- You are covering multiple apartments, colonies or commercial areas
- You want future-proof capacity without buying a second OLT soon
Quick Comparison
| Feature | 4 Port EPON OLT | 8 Port EPON OLT |
| PON Ports | 4 | 8 |
| Max Subscribers | 256 (1:64) | 512 (1:64) |
| Best For | Small ISPs, startups | Growing ISPs, large areas |
| Price (Adopt) | ₹22,525 | ₹48,000 |
| Power Supply | Single | Dual |
So, Which One Should You Pick?
Simple rule: buy for where your ISP will be in the next 12 months, not just today.
If you are just starting out with under 200 subscribers, the 4 port is the smarter move. Lower cost, same quality, and enough capacity to grow comfortably.
If you already have a good subscriber base or planning a large area deployment from day one — go straight to the 8 port. Adding a second OLT later when your network is live and subscribers are waiting costs more time and money than just getting the bigger one now.
