What Is the VSOL V1600D Mini?
The VSOL V1600D-MINI is the central active network device used on the service-provider side of an EPON fibre network.
It communicates with subscriber ONUs through a passive optical distribution network consisting of fibre cables, ODFs, PLC splitters, fibre closures, FAT boxes and drop cables.
| Component | Function |
|---|---|
| OLT | Controls and manages subscriber ONUs |
| PON SFP | Provides optical PON interface |
| ODF | Terminates feeder fibres |
| PLC Splitter | Splits one PON signal |
| Feeder Fibre | Carries signal toward distribution |
| FAT Box | Distributes connections |
| Drop Cable | Connects subscribers |
| ONU / ONT | Terminates fibre at customer |
| Router | Provides LAN and Wi-Fi |
Four EPON PON Ports
The V1600D-MINI provides four SFP-based EPON PON interfaces.
| PON Port | Maximum Split Ratio |
|---|---|
| PON 1 | 1:64 |
| PON 2 | 1:64 |
| PON 3 | 1:64 |
| PON 4 | 1:64 |
| Total Theoretical ONU Positions | 256 |
This means each port can serve its own geographical fibre distribution zone.
Maximum Subscriber Capacity
At different split ratios:
| Split Ratio | Subscribers per PON | Four-Port Total |
|---|---|---|
| 1:8 | 8 | 32 |
| 1:16 | 16 | 64 |
| 1:32 | 32 | 128 |
| 1:64 | 64 | 256 |
The 256 figure is a theoretical endpoint count. Actual subscriber capacity should be based on optical budget, bandwidth demand, uplink capacity and the intended customer packages.
1:64 Optical Split Ratio
VSOL specifies a maximum split ratio of 1:64 per EPON interface.
Possible splitter choices include:
| PLC Splitter | Outputs |
|---|---|
| 1x2 | 2 |
| 1x4 | 4 |
| 1x8 | 8 |
| 1x16 | 16 |
| 1x32 | 32 |
| 1x64 | 64 |
For many Kenyan ISP deployments, 1:16 or 1:32 can provide more optical margin and more bandwidth headroom per subscriber than using the maximum split immediately.
EPON Port Speed
Each PON interface operates at symmetrical 1.25 Gbps.
| Direction | Nominal Speed |
|---|---|
| Downstream | 1.25 Gbps |
| Upstream | 1.25 Gbps |
This bandwidth is shared among the ONUs connected to that particular PON tree.
Supported PON Modules
The V1600D Mini supports several EPON optical module classes.
| PON Module | Supported |
|---|---|
| PX20 | Yes |
| PX20+ | Yes |
| PX20++ | Yes |
| PX20+++ | Yes |
The optical module selected should match the network's fibre distance, splitter loss and total optical budget.
20 km Transmission Distance
VSOL specifies a maximum transmission distance of up to 20 km for the EPON interfaces.
Actual usable distance depends on:
PLC splitter loss
Fibre attenuation
Connector losses
Fusion splice losses
PON module class
Patch cord losses
Engineering safety margin
A network should always be designed using an optical power-budget calculation rather than distance alone.
EPON Wavelengths
| Direction | Wavelength |
|---|---|
| OLT to ONU | 1490 nm |
| ONU to OLT | 1310 nm |
VSOL specifies TX at 1490 nm and RX at 1310 nm.
Four Gigabit Uplink Ports
The V1600D Mini provides four 10/100/1000 Mbps RJ45 uplink interfaces.
| Interface | Quantity |
|---|---|
| 10/100/1000M RJ45 Uplink | 4 |
| PON SFP Slots | 4 |
| Out-of-Band Management | 1 |
| Console | 1 |
The uplinks can connect the OLT to equipment such as a MikroTik router, aggregation switch or ISP core network.
Backplane and Forwarding Performance
| Performance Metric | Specification |
|---|---|
| Backplane Bandwidth | 16 Gbps |
| Forwarding Rate | 11.904 Mpps |
| MAC Address Capacity | Up to 16K |
These specifications are listed in VSOL's V1600D-MINI datasheet.
ONU Auto Discovery
The V1600D-MINI supports ONU auto-discovery, link detection and remote software upgrades.
This can reduce installation time because the OLT can detect newly connected subscriber ONUs and allow the network administrator to authorize and configure them centrally.
Dynamic Bandwidth Allocation
The OLT supports Dynamic Bandwidth Allocation (DBA).
| DBA Benefit | Function |
|---|---|
| Dynamic Allocation | Shares upstream bandwidth according to demand |
| Better Utilization | Reduces wasted capacity |
| Subscriber Profiles | Supports different service levels |
| QoS Support | Helps prioritize services |
VLAN Support
VSOL lists support for port VLAN, VLAN tags and VLAN transparent transmission.
| VLAN Use | Example |
|---|---|
| Internet VLAN | Subscriber broadband |
| Management VLAN | OLT and ONU management |
| CCTV VLAN | IP surveillance |
| IPTV VLAN | Multicast video |
| Corporate VLAN | Business subscribers |
| Voice VLAN | VoIP services |
QoS Support
The OLT supports different LLID configurations, allowing users and services to be assigned different QoS treatment.
This is useful where an ISP offers:
Residential Internet
Business Internet
IPTV
CCTV
VoIP
Managed enterprise services
Port Isolation
The V1600D Mini supports port isolation between different ports, helping improve subscriber and network segmentation.
This is especially useful in shared FTTH access environments where customers should not communicate directly at Layer 2 unless explicitly allowed.
Rate Limiting and Bandwidth Control
The OLT supports port-based rate limitation and bandwidth control.
This gives network administrators another mechanism for managing service performance alongside upstream PPPoE, MikroTik queues or other subscriber-management systems.
IGMP and Multicast
The V1600D-MINI supports IGMP functionality as part of its Layer 2 feature set.
This is useful for multicast services such as IPTV, where one stream can be efficiently delivered to multiple subscribers.
RSTP Support
Rapid Spanning Tree Protocol is supported, helping prevent Layer 2 loops when the OLT is connected to switched network infrastructure.
Management Options
| Management Method | Supported |
|---|---|
| SNMP | Yes |
| Telnet | Yes |
| CLI | Yes |
| Out-of-Band Ethernet | Yes |
| Console | Yes |
VSOL lists SNMP, Telnet and CLI as supported management modes.
Compact Mini Design
One of the main advantages of the V1600D-MINI is its compact physical size.
| Physical Specification | Value |
|---|---|
| Length | 224 mm |
| Depth | 200 mm |
| Height | 43.6 mm |
| Weight | Approx. 2 kg |
| Form Factor | 1U Height |

The VSOL V1600D Mini 4-Port EPON OLT provides a useful balance between compact size and subscriber capacity. Its four independent PON interfaces can each support optical splitting up to 1:64, giving an ISP a theoretical maximum of 256 ONU positions while allowing the network to be divided into four separate distribution zones.
Its compact chassis is one of the product's main strengths. Measuring approximately 224 × 200 × 43.6 mm and consuming about 15 W, the V1600D-MINI can be deployed in smaller POPs and network cabinets where space and backup-power capacity are important considerations. Despite its small size, it still provides four Gigabit copper uplinks, DBA, ONU auto-discovery, VLANs, QoS and remote ONU management.
For a complete FTTH deployment, the OLT should be paired with compatible EPON optics and ONUs alongside a properly designed passive optical distribution network.
