VarioConnect 3HE: Modular Fibre Optic Rack-Mount Enclosure for Growing Networks
VarioConnect 3HE: Modular Fibre Optic Rack-Mount Enclosure for Growing Networks
The VarioConnect 3HE is a modular fibre optic rack-mount enclosure that, with its 3U design and space for up to 288 fibres, achieves one of the highest fibre densities on the European market. The modular 3U splice box is based on a flexible 7TE grid spacing and enables tool-free installation of various front modules for all common connector types from LC via SC and E2000 to MPO/MTP.
With a capacity of up to 12 splice modules per unit, the fibre optic enclosure provides the scalability needed for continuous FTTH rollout. The robust metal construction with 24 M20 cable glands ensures professional cable management even at the highest fibre densities.
Technical Specifications of the VarioConnect 3HE System
The modular 3U splice box follows the proven 19-inch standard and makes optimal use of available rack space. With a height of 133 millimetres (3U) and a depth of 300 millimetres, the system fits seamlessly into existing infrastructure.
- Maximum fibre capacity: 288 fibres per 3U
- Module grid: 7 unit spaces (TE) with 122.5 mm width
- Connector compatibility: LC, SC, E2000, ST, FC, MPO/MTP
- Cable glands: 24 × M20 connectors
- Empty enclosure weight: 1.2 kg
- Minimum bend radius: 30 mm per G.657 standard
The well-designed front operation concept allows complete access from the front, enabling maintenance work without system removal. Tool-free module mounting reduces installation time by up to 40 per cent compared to conventional systems.
Modular Design for Maximum Flexibility
The VarioConnect 3HE uses an intelligent building-block principle that enables different expansion levels and connector combinations. Each of the 12 available module slots can be individually equipped with splice modules, blanking plates or cable management elements.
| Module Type | Capacity | Connector Types | Application |
|---|---|---|---|
| Standard Splice Module | 24 Fibres | LC, SC | Standard Cabling |
| High-Density Splice Module | 48 Fibres | LC-Quad | Data Centres |
| E2000 Module | 24 Fibres | E2000 APC/PC | Industrial Environments |
| MPO Module | 72 Fibres | MPO-12/24 | Backbone Cabling |
Modules can be swapped during operation, which is particularly advantageous for staged network expansion or technical upgrades. The fibre optic enclosure thus grows with the demands of your network.
Professional Cable Management for Maximum Fibre Density
At fibre densities of up to 96 fibres per unit, systematic cable management becomes a critical success factor. The VarioConnect 3HE integrates multiple levels of cable routing that ensure clear and maintenance-friendly installation.
The 24 M20 cable glands are organised in four groups of six openings each, enabling logical separation of incoming and outgoing cables. Integrated strain relief prevents mechanical stress on delicate optical fibres.
- Structured cable routing through dedicated cable ducts
- Colour-coded marking systems per IEC 61754-15
- Integrated reserve loops for service work
- Excess length management through special winding devices
- Documentation options directly on the module
Standards Compliance and Certifications
The modular 3U splice box meets all relevant international standards for professional fibre optic installations. Compliance with IEC 61300-3-4 for optical connectors and EN 50173-1 for structured cabling systems is confirmed by independent test institutes.
Particular importance is the compliance with the new VDE guideline 0800-730, which since February 2024 governs the installation of fibre optic networks in buildings. The VarioConnect 3HE supports the required fire safety classes and enables standards-compliant installation in all building categories.

Applications and Use Cases
The VarioConnect 3HE fibre optic enclosure is suitable for different network levels and installation environments. From central switching offices via regional distribution points to in-building fibre termination units, the system covers all requirements of professional fibre optic networks.
| Application Area | Typical Fibre Count | Special Requirements |
|---|---|---|
| Data Centres | 144–288 Fibres | Maximum fibre density, MPO support |
| Utility FTTH Networks | 96–144 Fibres | Robustness, easy expansion |
| Industrial Installations | 48–96 Fibres | E2000 connectors, vibration resistance |
| Campus Networks | 72–144 Fibres | Flexibility, documentation |
In data centre environments, the high fibre density enables significant space savings. A mid-size data centre with 10,000 active fibre connections requires only approximately 35 rack units with the VarioConnect 3HE system instead of the usual 70 RU with conventional 48-port systems.
Installation and Commissioning
Tool-free mounting of the modular 3U splice box significantly reduces installation time. The well-designed snap-lock system allows modules to be installed or replaced in less than 30 seconds.
The installation process follows a systematic procedure that can be safely performed by less experienced technicians. Front-side operation eliminates the need for rear-side access, which is particularly advantageous in confined server rooms.
- Step 1: Install the enclosure in the 19-inch rack
- Step 2: Install the required splice modules
- Step 3: Route optical fibres through M20 cable glands
- Step 4: Splicing work and fibre storage in modules
- Step 5: Documentation and labelling
- Step 6: Final attenuation measurement per IEC 61280-4-1
Cost-Effectiveness and Operating Expenses
Investment in a VarioConnect 3HE fibre optic enclosure pays for itself through multiple factors. The high fibre density reduces required rack space by up to 50 per cent, resulting in direct savings in floor area and cooling costs.
The modular design enables demand-driven expansion without complete replacement of existing infrastructure. With typical growth rates of 20 to 30 per cent annually in FTTH networks, network operators can distribute their investments across multiple expansion stages.
Additional cost savings result from reduced maintenance time. The clear structure and professional documentation capabilities reduce troubleshooting and switchover time by an average of 40 per cent compared to unstructured installations.
Compatibility with Existing Infrastructure
The VarioConnect 3HE integrates seamlessly into established network structures. By supporting all common connector types, existing patch cables and active components can be reused.
The modular 3U splice box is fully compatible with legacy systems and enables staged migration. Hybrid configurations with different connector types in one system are easily achievable, which is particularly relevant for technology transitions from SC to LC or the introduction of MPO connections.
- Backward compatibility with legacy 19-inch systems
- Support for singlemode and multimode in one system
- Flexible combination of different connector types
- Integration into existing documentation systems
- Compatibility with all standard test equipment
