2-10U OLT – chassis systems
OLT chassis systems – flexible solutions for large networks
Modular OLT systems with a height of 2U to 10U are ideal for larger ISPs, city networks or data centers. With the ability to fit removable cards (GPON, XGS-PON, Combo) and redundant power supply, they allow for easy scaling and high availability. These chassis units can accommodate up to tens or hundreds of PON ports and offer a wealth of configuration options. Uplink SFP/SFP+ slots, management via CLI, SNMP and web, support for L3 functions and hot-swap modules are a matter of course. In addition, selected models also allow a mix of different types of cards in one chassis.
✅ Modular design | ✅ Support for both GPON and XGS-PON | ✅ Redundant power supply
✅ Hot-swap modules | ✅ 24/7 operational reliability | ✅ Ideal for larger projects and ISPs

Who are OLT chassis units suitable for?
For medium and large internet providers, metropolitan networks, data centers and projects with a requirement for scalability and redundancy.
What is the main difference compared to 1U OLT units?
Chassis systems allow for the installation of more interchangeable cards, redundant power supply, greater PON port capacity and higher customization.
Can GPON and XGS-PON cards be combined in one chassis?
Yes, most chassis support a combination of different PON lane types – including Combo cards for flexible deployment.
What is a hot-swap and why is it important?
Hot-swap means the ability to replace modules on the fly without downtime. It ensures high availability and simplifies service.
What power supply do these systems support?
Mostly AC and -48V DC. Redundant power supplies are common to allow uninterrupted switching in the event of a fault.
How big a network can be served with an OLT chassis?
For example, a chassis with 15 service slots with 16× GPON cards can serve up to 30,720 users at a split ratio of 1:128 – depending on the specific configuration.
How is a modular OLT managed?
Through central management – CLI (SSH/Telnet), Cloud management or another NMS tool. Some models can also be managed via a web interface.
What are the dimensions of these chassis?
2U to 10U depending on model. The chassis are designed for mounting in a 19" rack. Each model has its own specifications – listed with the product.
Are these units suitable for 24/7 operation?
Yes, they have redundant power supplies, hot-swap components, industrial ventilation and are built for continuous operation.
Can you help with designing a tailor-made solution?
Definitely. We offer consultations, topology design, delivery, configuration and possible SLA service packages.
