ODF Systems: Modular 19″ Fiber Distribution Frames for Professional Networks
Our ODF systems (Optical Distribution Frame) offer maximum flexibility for large fiber optic installations. The 3U chassis can accommodate up to 288 fibers per system through modular 7HP architecture. Perfect for data centers, telecommunications and campus networks.
High density in three rack units: three points that count up front
Density is not an end in itself. It pays off where rack space is more expensive than the assembly.
Rack space is the scarce resource
In data centres and network nodes, the rack unit costs more than what goes into it. That is where density pays off first.
Expanding without rebuilding
Choose the right subrack and you add modules later. Choose one too small and you replace the whole level.
The connector interface follows the installed base
LC, SC, E-2000 and ST on the same module grid — the expansion fits the installed base.

Four reasons to plan the 3U system with us
Made in Europe
The F4P systems are manufactured in Europe — short paths from design to production, even for custom populations.
Populate as needed instead of buying it full
The subrack sets the grid, the modules fill it — the level grows with the network instead of being paid for up front.
Data sheet and part number for every version
Every available version is documented. The enquiry goes out with the part number, not with a description.
One connector system across the entire line
The same E-2000® connection level in every form factor: consistent handling, one spare-parts profile, no system breaks in the installed base.
Calculate and configure first, then enquire
Three tools with real part numbers — check the optical budget and put your configuration together live in 3D.
Attenuation budget calculator
Add up connectors, splices and fibre lengths and check the total attenuation against the budget — before the OTDR acceptance test measures it.

Important answers about modular 19″ fiber optic distribution frames with up to 288 fibers and flexible 7HP architecture for professional networks
What does the VarioConnect 3U System deliver in fiber optic distribution?
Maximum port density: Up to 288 fibers in just 3 rack units – significantly more than conventional systems.
Modular flexibility: 7HP architecture with combinable splice modules and front modules for individual configuration.
Professional cable management: Structured fiber management prevents cable mess and enables maintenance-friendly installation.
Standards-compatible: 19″ rack mounting with robust aluminum construction for professional environments.
Which connector variants are supported?
LC connectors: High packing density for modern fiber optic networks and data center applications.
SC connectors: Proven solution for backbone connections and industrial applications.
E2000 connectors: DIAMOND E2000 for Swiss precision with automatic shutter cap system.
MPO/MTP connectors: Highest port densities for datacenters and high-speed connections up to 400G.
Flexible combination: Different connector types can be operated in parallel in one system.
For which applications is the 3U system ideal?
Data centers: Maximum port density for datacenters with 40G/100G/400G connections and highest space requirements.
Telecommunications: FTTH deployment for carriers with up to 288 end-customer connections per system.
Campus networks: Central fiber optic distribution for universities and large corporate premises.
5G backbone: High-performance connections for mobile network infrastructures and antenna connections.
How does scalable expansion work?
Modular design: Start with few modules and expand gradually up to full configuration with 288 fibers.
Future-proof: Module change instead of system change for technology updates – from LC to MPO or higher port densities.
Investment protection: The 3U module carrier remains, only modules are exchanged as needed.
Example: Telecommunications provider starts with 144 fibers and later upgrades to 288 fibers.
Are pre-configured solutions available?
Plug-and-play systems: Completely pre-configured 3U units significantly reduce installation time.
Project-specific: Individual fiber lengths and connector types according to your planning documents.
Quality assurance: Professional manufacturing with test protocols for every fiber under controlled conditions.
Fast commissioning: Systems are ready for use immediately after rack mounting without extensive on-site work.
What distinguishes VarioConnect 3U from other ODF systems?
Highest port density: Up to 288 fibers in 3U – significantly more than conventional systems with 144-216 fibers.
European quality: European manufacturing and Swiss DIAMOND E2000 precision.
Modular flexibility: 7HP architecture enables any combinations of singlemode and multimode in one system.
Future-proof: Module change instead of system change for technology updates or expansions.
How does configuration and ordering work?
