This is a 1U, 19-inch EPON OLT built for projects that need a real headend without a chassis. Eight EPON ports run at 1.25 Gbps in both directions, each port supports a 1:64 split and the unit addresses up to 512 ONUs. The uplink side carries eight GE RJ45 ports, four SFP ports and four SFP+ ports, with a 128 Gbps backplane and 89.28 Mpps forwarding rate.
The optical interface is SC/UPC on 9/125 µm single-mode fibre, transmitting at 1310 nm and receiving at 1490 nm. Transmit power is +4.5 to +9 dBm, receiver sensitivity is −32 dBm and the overload point is −8 dBm, with a 20 km reach. Those figures are the ones to put into a link budget before choosing splitter ratios; a 1:64 split consumes about 20.5 dB before connectors and splices are counted.
Layer 2 and Layer 3 features cover the usual project requirements: 4096 VLANs, QinQ, 16K MAC addresses, IGMP snooping for 256 multicast groups, DHCP server/relay/snooping, port isolation, ACL, link aggregation and static routing with RIP/OSPF. Management is available over SNMP, Telnet, CLI, web and SSH, and the unit can run from AC 100–240 V or −48 V DC at 55 W.

Engineering features
What changes on site.
Eight ports in one RU
Up to 512 ONUs in a 1U footprint. At 1:64 and 60% fill, eight ports cover roughly 307 active ONUs before the next shelf is needed.
DBA and QoS per LLID
Dynamic bandwidth allocation, per-port rate limiting and multiple LLIDs let CCTV, data and voice share the PON without one service starving another.
Project-grade L2/L3
VLAN isolation, QinQ, IGMP snooping, DHCP snooping, ACL, port mirroring and RSTP/MSTP are available without an extra aggregation switch.
IPv6 ready
IPv6 static and dynamic routing (RIPng, OSPFv3), DHCPv6 and MLD snooping are supported alongside IPv4.
AC or DC feed
AC 100–240 V for premises; −48 V DC for a telecom room or battery plant. Power draw is 55 W.
Field diagnostics
ONU auto-discovery, link detection, remote firmware upgrade, dying-gasp alarm and EMS distance measurement shorten fault finding on a live ODN.
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.
| Network type | Why EPON fits | Watch-out |
|---|---|---|
| CCTV / security campus | Symmetric 1.25 Gbps is ample for camera upload; ONUs are inexpensive | Camera VLAN and multicast plan must be set before handover |
| Small FTTH / ISP edge | Eight ports cover a village or estate without a chassis | Check uplink: 8×GE may bottleneck if all ports run at line rate |
| Hotel / campus data | One ODN for data, voice and IPTV | Separate VLANs and QoS for IPTV and guest Wi-Fi |
If the existing headend or ONU stock is GPON, use the GPON OLT instead; EPON and GPON ONUs are not interchangeable on the same PON port.
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

8-Port EPON 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 engineerDoes this OLT support 1:128 splitting?
The datasheet rating is 1:64 per PON port, with a maximum of 64 ONUs per port and 512 ONUs on the unit. Plan within that rating; a higher ratio reduces optical margin and is not the published configuration.
How far can the PON run?
20 km on the specified optics. The real limit is the optical budget after the splitter, connectors and splices. A 1:64 split leaves little margin at 20 km; a 1:32 or 1:16 split is safer for long rural spans.
Can I mix EPON and GPON ONUs on this OLT?
No. This is an EPON OLT. GPON ONUs need a GPON OLT (or an XPON ONU configured for EPON). Mixing technologies on one PON port will not register.
Is it suitable for IPTV?
Yes, with IGMP snooping and 256 multicast groups. Put IPTV on its own VLAN and reserve bandwidth in the DBA profile; do not rely on best-effort for live channels.
What uplink should I use?
Eight GE RJ45 ports are enough for a 4–6 Gbps aggregate; use the SFP+ ports for 10G trunking to the core. Do not oversubscribe the uplink more than 4:1 if all PON ports carry paid services.
What is included with the OLT?
The unit, rack ears, power cable and the model datasheet. PON SFP optics, uplink SFP modules, ODF and splitters are quoted separately so the connector and reach match the ODN.

Need a 8-Port EPON OLT configuration checked?

No obligation. The plan states its assumptions so your engineer can check it.
