DIAMOND Splice Boxes & Splice Modules
Six product families covering the complete spectrum of professional fibre optic splice management — from rigid 1U Fusion Boxes for fixed installations through extendable Future Boxes for service-oriented racks to compact wall distribution modules on DIN rail. All built around the DIAMOND E-2000® CompactRJ connector system, all measured to 100% before shipment.
Six families, one decision: three points that decide it in advance
The families differ in form factor and access, not in the connector system — that makes the choice simpler than it looks.
Rack or wall?
The first question is not the port count but the installation location. It rules out half the families straight away.
Fixed or pull-out?
How often will rework be needed? Answer that and you have made the second half of the decision.
The common basis
All families carry the same E-2000 CompactRJ connection level — which is why they can be mixed within the same network.
Not sure which family fits?
Since the DIAMOND press release of 27 April 2026, Fiber Products GmbH is the central supplier for the 19″ enclosure technology. DIAMOND has discontinued in-house production of these form factors but retains the entire connector and component range in its own manufacturing in Losone, Switzerland.

The Six DIAMOND Splice-Box Families
Each family answers a different installation challenge. The choice depends on fibre count, mounting environment, and whether you need fixed or service-friendly access.
| Family | Form Factor | Typical Use | Detail Page |
|---|---|---|---|
| Fusion Box | Rigid 1U rack | Fixed cabling, low-maintenance installations, high port density | View Fusion Box → |
| Future Box | Sliding 1U / 2U rack | Service-friendly racks, frequent maintenance, regulated environments | View Future Box → |
| Compact Modules 7TE | 7TE slide-in module | High-density centres, scalable fit-out in 4U carrier systems | View Compact Modules → |
| 4U Carrier System | Modular 19″ chassis | Hosts up to 12 Compact Modules — up to 144 fibres in 4U | View Carrier System → |
| Wall Distribution Modules | DIN 35 mm hat rail | Switching cabinets, outdoor distribution, decentralised nodes | View Wall Distribution → |
| E-2000® Components | Connectors, adapters, pigtails | Building blocks for any of the above + custom builds | View E-2000 Range → |
A test report with every unit
Every pre-terminated unit comes with a measurement report from production in Losone. Across six families that means the same proof, whichever form factor is installed in the end.
The Common Foundation: DIAMOND E-2000® CompactRJ
Every splice-box family uses the DIAMOND E-2000® CompactRJ coupling system as its connector core. The system delivers:
- Connector design: Push-pull latch with spring-loaded shutter — automatic laser safety on disconnect, end-face protected against dust
- Ferrule: Zirconia with titanium insert, 2.5 mm standard diameter
- Active Core Alignment (ACA): Patented micro-alignment of the fibre core during assembly — typical insertion loss ≤ 0.1 dB
- Configurations: Singlemode PC (blue), Singlemode APC (green, 8° polish), Multimode (OM3, OM4, 62.5 μm in standard colour codes)
- Optional: IP65-protected variants for outdoor and industrial applications, on request
The result: a consistent connector experience across every form factor, full intermateability between families, and a single training/spare-parts profile across your fibre infrastructure.
Quality Assurance: Test Certificate for Every Pigtail
Every pigtail shipped from the DIAMOND production goes through individual measurement — not sample inspection. The test certificate documents:
- Connector end-face quality (visual and interferometric)
- Tilt angle (maximum ≤ 0.4°)
- Concentricity (maximum 0.25 μm)
- Final inspection “passed” as binding release criterion
Each certificate is available on request. This individual traceability is critical for public-sector tenders, regulated industries (railway, energy, healthcare) and quality-managed network operators.
Four reasons to source DIAMOND through us
Authorised distribution partner of DIAMOND SA
Swiss precision from a single source — E-2000® with typ. ≤ 0.1 dB insertion loss and a spring-loaded laser protection shutter.
Six families on one shared connection level
From the fixed 1U box to the wall distribution box: the same connector interface, the same spare parts basis, different form factors.
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.
DIAMOND configurator (3D)
Configure Future and Fusion Box with E-2000 live — with a real part number for each configuration, ready for your enquiry.
Subrack configurator
Populate a 19″ subrack slot by slot with splice and front modules — including the bill of materials for your quotation.
Fiber Products as the Central DACH Supplier
Fiber Products GmbH is the authorised production partner of DIAMOND SA. Our role has two dimensions:
Own manufacturing with DIAMOND components: We produce modular splice systems (1U splice boxes, 3U/4U ODF systems, DIN-rail boxes) in our European facility, populated with DIAMOND E-2000 CompactRJ couplings. This combines Swiss precision connectors with European manufacturing logistics — Manufacturer warranty included.
Authorised distribution of DIAMOND originals: The complete Fusion Box, Future Box, Compact Module, Wall Distribution, Carrier System and E-2000 connector range — with fast DACH delivery and expert advice on the right form factor for your specific use case.

How to Choose the Right Family
The same system technology, a different form factor and different fields of application.
A short selection guide based on the typical installation challenge:
- If you need a fixed rack installation with high port density and low maintenance — start with Fusion Box (rigid 1U)
- If you need rack installation but want sliding service access — Future Box (1U or 2U)
- If you need scalable density in a single chassis — 4U Carrier System with up to 12 Compact Modules
- If you need DIN-rail mounting in switching cabinets or outdoor — Wall Distribution Modules
- If you have a custom requirement — F4P-manufactured solutions with DIAMOND components, built to your specification
