No active equipment in between
Passive splitters replace street cabinets and floor switches: less power, less cooling, fewer failures.

One fibre for every service, from the street to the desk
Passive optical networks carry Internet, voice, IPTV, CCTV and Wi-Fi over a single fibre for up to 20 km, with no powered equipment between the central office and the user. The Navijin Optical Access family brings GPON, 10G XGS-PON and EPON systems to ISPs, building operators, hotels, campuses and enterprises.

Why fibre access
What GPON changes for operators and building owners
Long reach, huge capacity
Up to 20 km from OLT to user, with gigabit and multi-gigabit service on the same fibre plant.
Lower cost per subscriber
One OLT port serves up to 128 GPON or 256 XGS-PON users through optical splitters.
Future-proof cabling
Upgrade from GPON to XGS-PON by changing the electronics, not the fibre.
Every service on one network
Internet, SIP voice, IPTV, CCTV, building systems and Wi-Fi backhaul share one managed platform.
Central control
ONUs are provisioned, monitored and upgraded remotely from the OLT.
Architecture
How a Navijin fibre access network is built
A typical design from the core to the user. Navijin Optical Access products are available to partners on request; existing Navijin products complete the network.
- L1
Core & Internet edge
Layer 3 core switches with 10G/100G uplinks connect the OLTs to the Internet, the data center and service platforms.
- L2
OLT (optical line terminal)
Rack-mount GPON, XGS-PON or EPON OLTs, or modular chassis OLTs for large operators, in the central office or main equipment room. Combo ports run GPON and XGS-PON subscribers side by side.
- L3
Optical distribution network
Passive splitters (1:8, 1:16, 1:32, 1:64) in fibre distribution boxes, with single-mode fibre to each building, floor or home. Type B/C protection paths for critical sites.
- L4
ONU / ONT
SFU bridges, Wi-Fi 6 home gateways with voice, PoE ONUs for cameras and access points, and 8- to 24-port MDUs for floors and buildings.
- L5
Services at the edge
Navijin Wi-Fi access points, IP cameras and IP phones connect to ONUs, powered by PoE where needed.
- L6
Management
OLT-based ONU provisioning and monitoring, plus Navijin Cloud for sites, gateways and Wi-Fi.

| Typical split ratio | 1:32 – 1:64 | 1:64 – 1:128 | 1:64 – 1:256 |
| Best for | Cost-sensitive FTTH and FTTB | Mainstream FTTH, hotels, campuses | Multi-gigabit homes, businesses, 5G and Wi-Fi 7 backhaul |
| Coexistence | – | Runs with XGS-PON on combo ports | Runs with GPON on combo ports |
Real capacity per user depends on split ratio, traffic profile and service plans.

FAQ
Frequently asked questions
What is GPON?
GPON (Gigabit Passive Optical Network, ITU-T G.984) delivers 2.5 Gbps downstream and 1.25 Gbps upstream per fibre port, shared through passive splitters by up to 128 users over distances up to 20 km.
What is the difference between GPON and XGS-PON?
XGS-PON offers 10 Gbps symmetric capacity, four times GPON downstream and eight times upstream, for multi-gigabit services. Combo OLT ports let both run on the same fibre.
What is the difference between an OLT and an ONU?
The OLT (optical line terminal) sits in the central office or main equipment room and controls the PON. The ONU or ONT (optical network unit or terminal) sits at the user side and provides Ethernet, Wi-Fi, voice or PoE ports.
Is GPON suitable for hotels and offices?
Yes. Passive optical LAN uses GPON inside buildings to replace floor switches and copper, reducing power, space and maintenance.
How do I get Navijin Optical Access products?
Navijin Optical Access products are available to partners through the Navijin sales team. Ask for the Optical Access catalog and a design consultation.
