What this model is for
8-Port EPON OLT
Specifications are taken from the model datasheet. Final configuration is confirmed on the quotation.
V1600D8 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 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.
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 highlights
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.

V1600D8: 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 V1600D8 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.
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.
Does it support ONU auto-provisioning?
It supports profile-based ONU provisioning, but the managed fields depend on the firmware and the ONU model. Test one ONU of each type on the actual OLT before a batch order, and record the profile in the as-built.
Next step
Need V1600D8 checked against your site?
Send the endpoint count, the longest run, the power condition and the destination. We return the optical/power budget and the quotation assumptions.
No obligation. The plan states its assumptions so your engineer can check it.
