VarioConnect 4HE, 288-fibre splice box, telecom splicing solutions: maximum packing density for network deployment

For telecommunications operators with high fibre counts and limited rack space, the VarioConnect 4HE is the logical evolution of the modular principle: up to 288 fibres in a compact 4-rack-unit (4HE) enclosure, fully modular and compatible with all common connector types. Here is an overview of what the system delivers technically and where it excels.

As a manufacturer and official Diamond Partner, Fiber Products offers the VarioConnect 4HE system as a solution that delivers 72 fibres per rack unit. This represents double the packing density compared to conventional 19-inch systems and meets rising requirements in backbone and distribution network areas.

Technical specifications of the VarioConnect 4HE splice box

The VarioConnect 4HE system is based on a well-designed modular concept that combines maximum flexibility with exceptional packing density. The basic construction consists of a 19-inch module per IEC 60297-3 with a height of 177 mm (4HE) and a depth of 300 mm.

Technical data	Specification
Maximum fibre capacity	288 fibres
Rack units	4HE (177 mm)
Mounting depth	300 mm
Splice cassettes	Up to 12 cassettes × 24 fibres
Front modules	6 modules × 48 fibres
Connector types	LC, SC, E2000, ST, FC, MPO
Standards compliance	IEC 61756, IEC 61754

The modular design allows free configuration of the front modules. Each of the six front modules can be fitted with different connector types, enabling efficient management of heterogeneous network structures.

Structure and modularity for telecommunications networks

The VarioConnect 4HE system is characterised by its consistently modular architecture. The foundation is a robust steel sheet enclosure with integrated cable routing and strain relief for up to 12 cable entries.

• Exchangeable front modules for different connector types
• Pivoting splice cassettes with 60 mm bend radius
• Integrated fibre slack management
• Tool-free module exchange during operation
• Labelling fields per DIN EN 50173-1
• Colour coding for different network levels

The splice cassettes are individually pivoting and allow access to underlying cassettes without operational interruption. This significantly reduces maintenance time and minimises the risk of fibre damage.

Applications in telecommunications infrastructure

The VarioConnect 4HE, 288-fibre splice box, telecom splicing solutions are used in various areas of network infrastructure. In the backbone area, they serve as central distribution points for regional and national optical fibre connections.

In main distribution frames of municipal networks, the high packing density enables efficient management of thousands of fibres in minimal space. The advantage of the modular design is particularly evident during FTTH (Fibre to the Home) network rollouts.

Fiber Products quality promise: As an official Diamond Partner and manufacturer, we produce modular splice systems in Europe. Benefit from Swiss precision and 5 years warranty on our systems.

Installation and assembly of the VarioConnect 4HE splice box

Installation of the VarioConnect 4HE system is standard in 19-inch cabinets per IEC 60297. The system comes with pre-assembled mounting hardware and can be inserted directly into the cabinet rails.

• Pre-assembled cable entries with sealing elements
• Integrated strain relief for cables 8–28 mm diameter
• Earthing concept per DIN EN 50310
• Tool-free assembly of front modules
• Pre-terminated pigtails optionally available

The average installation time for a fully equipped 288-fibre unit is under 4 hours when using pre-assembled modules. This significantly reduces installation costs and minimises downtime during network deployment.

Scalability for growing telecom networks

A key advantage of the VarioConnect 4HE, 288-fibre splice box, telecom splicing solutions is stepless scalability. The system can start with a basic configuration of 48 fibres and be expanded to maximum capacity as needed.

Expansion stage	Fibre count	Modules	Application
Basic	48 fibres	1 front module	Small distribution points
Standard	144 fibres	3 front modules	District distributor
Extended	192 fibres	4 front modules	Main distributor
Maximum	288 fibres	6 front modules	Backbone node

This flexibility enables network operators to invest according to demand and avoids over-capacity in the early phase of network deployment.

Documentation and network management

Professional network management requires complete documentation of all optical fibre connections. The VarioConnect 4HE system supports this through integrated labelling fields and consistent system logic.

Each splice cassette has labelled identification fields for unambiguous fibre assignment. The front modules provide space for port descriptions per TIA-606-B standard. Additionally, QR codes can be attached for digital documentation.

• Colour-coded cassettes for different network levels
• Integrated cable routing with labelling fields
• Documentation folders for splice records
• Compatibility with common documentation systems
• OTDR measurement values directly documentable at port

Quality features and standards compliance

The VarioConnect 4HE, 288-fibre splice box, telecom splicing solutions meet all relevant international standards for professional optical fibre installations. Manufacturing is carried out according to ISO 9001:2015 certified processes at European production facilities.

All connectors comply with the requirements of the IEC 61754 series and guarantee attenuation values of < 0.25 dB for single-mode applications. The mechanical design exceeds the specifications of the IEC 61300-2 series for vibration and shock resistance.

As a Diamond Partner, Fiber Products ensures consistently high quality through continuous quality control and 5-year warranty on all system components.

Maintenance and operational safety

The operational safety of telecommunications networks depends significantly on the maintainability of installed components. The VarioConnect 4HE system was developed with a focus on minimal maintenance time.

• Front-side access to all components
• Individually pivoting splice cassettes
• Module replacement without operational interruption
• Dust protection caps for unequipped ports
• Cleaning access without dismantling
• Spare parts availability guaranteed for 10 years

The modular design allows replacement of individual components within minutes. This reduces downtime and significantly increases network availability.

Integration into existing infrastructure

The VarioConnect 4HE, 288-fibre splice box, telecom splicing solutions integrate seamlessly into existing 19-inch infrastructure. Compatibility with all common cabinet systems is ensured through standards compliance per IEC 60297.

For migration of existing networks, the system offers various transition solutions. Hybrid modules enable combination of different connector types, whilst adapter solutions simplify the transition between different generations of optical fibre networks.

Frequently asked questions about the VarioConnect 4HE splice box

How many different connector types can be combined in one VarioConnect 4HE?

Each of the six front modules can be equipped with a different connector type. Thus, theoretically six different connector types (LC, SC, E2000, ST, FC, MPO) can be combined in one unit.

Is it possible to expand the fibre capacity later?

Yes, the system is modular and can be expanded at any time from 48 to 288 fibres. Expansion is done by adding additional front modules and splice cassettes.

Which cable types can be connected?

The universal cable entries accept cable diameters of 8 to 28 mm. This covers all common outdoor cables, indoor cables and breakout cables for telecommunications networks.

How are splice connections documented?

Each splice cassette has integrated documentation fields. Additionally, digital documentation systems can be connected via QR codes or RFID tags.

What warranty does Fiber Products offer?

Fiber Products provides 5 years warranty on all VarioConnect systems. This covers material and manufacturing defects with proper use.

Are installation trainings available?

Yes, Fiber Products offers regular training for installers and network technicians. The trainings include theory and practical exercises on the system.
