A 10G PON OLT is the headend for XGS-PON, XG-PON or 10G EPON services. XGS-PON runs 10 Gbps in both directions, XG-PON runs 10 Gbps downstream and 2.5 Gbps upstream, and 10G EPON offers 10/1 or 10/10 Gbps depending on the variant. The chassis uses the same ODN discipline as GPON: splitters, connectors and splices decide the optical budget, and the port count decides how many subscribers share it.
The practical value of a chassis is the board mix. A two-slot chassis can start with a few 10G PON ports and grow to 32; a seven-slot chassis reaches 112 PON ports with 100GE uplinks. That lets an operator add 10G services to a GPON headend without replacing the fibre plant, or build a new business-access network with a smaller initial board count.
Coexistence is the other design decision. XGS-PON uses 1577 nm downstream and 1270 nm upstream; GPON uses 1490/1310 nm. A WDM coexistence element at the headend lets both share the same ODN, while the splitter and connectors must be rated across the full band. The board mix, coexistence element and uplink are confirmed together on the quotation.
Configuration table
The numbers that decide the fit.
Values are from the model datasheet. Where a value is model-dependent, the table says so instead of guessing.
| Platform | PON generation | Max PON ports | Uplinks | Typical use |
|---|---|---|---|---|
| 2-slot chassis | XGS-PON / XG-PON / 10G EPON | Up to 32 | 2× 100GE QSFP28 | Business FTTH, campus |
| 7-slot chassis | XGS-PON / XG-PON / 10G EPON | Up to 112 | 2× 100GE QSFP28 | District 10G headend |
| GPON coexistence | GPON + XGS-PON | Per WDM plan | 2× 100GE QSFP28 | Upgrade an existing ODN |
Port count and PON generation depend on the service-board mix. Confirm the boards, coexistence element and uplink on the quotation.
Engineering features
What changes on site.
10G symmetric
XGS-PON gives 10 Gbps in both directions; XG-PON and 10G EPON are available for the upstream/downstream mix the operator needs.
Board-level growth
Start with a few ports and add boards as the ODN fills. The same chassis can mix PON generations if the boards and coexistence plan allow it.
100GE uplinks
Two 100GE QSFP28 uplinks remove the uplink bottleneck when 32–112 PON ports carry paid services.
Coexistence
A WDM element lets XGS-PON share the ODN with GPON; the splitter and connectors must cover 1270–1577 nm.
One management path
OMCI for ONUs, SNMP/CLI for the OLT, and the same VLAN and QoS model as the GPON family.
AC and DC power
AC and −48 V DC options for premises and telecom rooms; confirm the power configuration per chassis.
Selection guide
Which configuration fits which site.
Start from the site, not from the model. The table is a starting point; the final check is the optical and power budget.
| Project | Recommended | Why |
|---|---|---|
| Business 10G services | 2-slot chassis + 10G boards | Start with 8–16 ports and grow to 32 |
| District 10G headend | 7-slot chassis | Up to 112 PON ports and 100GE uplinks |
| GPON upgrade | Coexistence + XGS-PON boards | Reuse the existing ODN and add 10G services |
| 10G EPON network | 10G EPON boards | Asymmetric or symmetric 10G EPON, depending on the ONU |
The split ratio, ONU type and coexistence element must be confirmed against the ODN before the board order.
Integration
Where it sits in the chain.
The PON chain starts at the OLT port, passes through the splitter and the ODN, and ends at the ONU. The split ratio and the connector count decide the optical margin.
- One bill of materials for the whole chain
- Connector polish and PON mode confirmed before order
- Model-level test data supplied with the shipment

10G PON / XGS-PON OLT: questions before the order.
If your question is not here, send the site details and we will answer with the calculation, not a brochure.
Ask an engineerWhat is the difference between XGS-PON and XG-PON?
XGS-PON is 10 Gbps symmetric; XG-PON is 10 Gbps downstream and 2.5 Gbps upstream. XGS-PON is the usual choice for symmetric business services; XG-PON fits downstream-heavy residential profiles.
Can I add XGS-PON to an existing GPON ODN?
Yes, with a coexistence element at the headend. XGS-PON uses 1577/1270 nm and GPON uses 1490/1310 nm; the splitter and connectors must be rated across the full band, and the optical budget must include the coexistence loss.
How many 10G PON ports can the chassis hold?
Up to 32 in the two-slot chassis and up to 112 in the seven-slot chassis, depending on the service boards. The exact count and uplink configuration are confirmed on the quotation.
Do I need a different fibre?
No. Standard single-mode fibre (G.652D or G.657A2) works. The splitters, connectors and coexistence element must be rated for the 1270–1577 nm band.
What split ratio should I use?
1:64 is a common starting point; 1:32 leaves more margin for long spans. The splitter loss is about 16.5 dB at 1:32 and 20.5 dB at 1:64, before connectors and splices.
Do you supply the 10G ONUs with the OLT?
Yes. The 10G ONU, splitter, ODF and patch cords are quoted as one chain so the PON mode, connector polish and management profile match the OLT.
