DIAMOND SA (Switzerland) · Swiss Engineering · Made in Europe by Fiber Products
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.
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 → |
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 accessible via QR code on the component or through shop.diamond.de. This individual traceability is critical for public-sector tenders, regulated industries (railway, energy, healthcare) and quality-managed network operators.
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 German facility, populated with DIAMOND E-2000 CompactRJ couplings. This combines Swiss precision connectors with German manufacturing logistics — 5-year 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
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
