DIAMOND Fibre Optics: What Swiss Precision Means for Network Deployment
DIAMOND Fibre Optics: What Swiss Precision Means for Network Deployment
DIAMOND SA from Losone (Ticino, Switzerland) has developed and manufactured high-precision fibre optic components since 1980 — best known as the inventor of the E-2000® connector, today an industry standard in critical infrastructure worldwide. This article explains what Swiss precision manufacturing means in practice, what technical advantages result from it, and how Fiber Products, as an authorised production partner of DIAMOND SA, brings this quality to the DACH market.

For IT system integrators, municipal utilities and network operators, choosing DIAMOND components means measurable quality improvements in fibre optic cabling. The patented Active Core Alignment (ACA) technology and continuous in-house manufacturing in Switzerland deliver reproducibly low insertion loss — typically ≤ 0.1 dB for E-2000 connectors with ACA specification.
From Precision Mechanics to Fibre Optics: DIAMOND SA Since 1958
DIAMOND SA was founded in 1958 in Locarno — originally as a specialist in the precision machining of ultra-hard materials such as ruby, sapphire, tungsten carbide and diamond. From this metrological heritage stem both the company name and today’s core competence: mastering tolerances at the micrometre scale.
In 1979 the company entered the fibre optics industry and launched its first own connector series in 1980. Today, DIAMOND manufactures in a 13,500 m² facility at its Losone headquarters, exclusively producing fibre optic components — from connectors through patchcords to complete distribution systems.
- Active Core Alignment (ACA): Patented active micro-positioning of the fibre core during connector assembly — the basis for reproducibly low insertion loss
- Harsh-environment solutions: E-2000 with IP65 protection for outdoor and industrial applications (available on request)
- Reference patchcords: Certified test connectors for calibration of fibre optic measurement systems
- Backplane connectors (E-2000 PS): High-density connections for data centre architectures
The E-2000 Connector — DIAMOND Invention, Worldwide Standard
The E-2000 was developed by DIAMOND and has established itself since the early 1990s as the preferred connector for high-availability networks. Its characteristic push-pull latching mechanism with spring-loaded shutter prevents contamination of the connector end face and provides automatic laser safety on disconnection.
Key constructional features:
- Ferrule: Zirconia with titanium insert, standard 2.5 mm diameter
- Latching: Push-pull latch — engages automatically on insertion, released at the side lever
- Shutter: Spring-loaded, protects against dust and end face contact
- Colour coding: Interchangeable colour-coded frames and coding plates for unambiguous PC/APC identification and mating-error prevention
- Configurations: PC (Physical Contact) and APC (Angled Physical Contact, 8° polish)
The standard colour coding follows a clear convention: green for singlemode APC, blue for singlemode PC, beige variants for multimode (OM3, OM4, 62.5 μm) — a system DIAMOND helped establish and which is recognised industry-wide today.
What “Swiss Precision” Means in Measured Values
Active Core Alignment technology is the cornerstone of the DIAMOND quality chain. During assembly, the fibre core is actively aligned within micrometre tolerances relative to the ferrule end face — not passively averaged geometrically. The result is reproducibly low insertion loss unachievable with standard connectors.
Concretely, DIAMOND tests every connector individually before shipment. The inspection certificate documents for each pigtail:
- Connector end face (visual and interferometric)
- Tilt angle (max. ≤ 0.4°)
- Concentricity (max. 0.25 μm)
- Final inspection “passed” as binding release criterion
The inspection certificate is available for each connector via QR code or the DIAMOND online shop — full traceability from production batch to individual pigtail.
Fiber Products as Authorised Production Partner
Fiber Products GmbH is an authorised production partner of DIAMOND SA. This partnership has two pillars:
First pillar — own manufacturing with DIAMOND components: We produce modular splice systems (1U splice boxes, 3U/4U ODF systems, DIN-rail boxes) in our own facility in Germany — populated with DIAMOND E-2000 CompactRJ couplings. This combines Swiss precision connectors with German manufacturing logistics and fast DACH availability.
Second pillar — distribution of DIAMOND original products: Complete DIAMOND product lines available directly through us: Fusion Box, Future Box, Compact Modules 7TE, wall distribution modules, carrier system, and the complete E-2000 connector and adapter range.
Strategic note: Following the DIAMOND press release of 27.04.2026, DIAMOND has discontinued in-house production of the 19″ enclosure technology. Availability of splice boxes and distribution housings now runs through Fiber Products GmbH as the selected partner. For existing customers this means: seamless supply with the familiar Swiss quality.
Typical Application Areas for DIAMOND Components
DIAMOND technology delivers its greatest value where low insertion loss, high availability and serviceability over many years are essential:
| Application Area | Recommended DIAMOND Component | Primary Reason |
|---|---|---|
| FTTH backbones | E-2000 APC + Future Box | High return loss, service-friendly design |
| Data centre | E-2000 PS Backplane, Compact Modules 7TE | High-density architecture in 4U carrier systems |
| Industrial / outdoor | E-2000 with IP65 + wall distribution modules | Robust aluminium housing, DIN-rail mounting |
| Railway / public transport | E-2000 standard | Vibration resistant, automatic laser safety on disconnect |
FAQ: DIAMOND Fibre Optics in Practice
What distinguishes DIAMOND E-2000 from standard connectors like LC or SC?
The key difference is the Active Core Alignment (ACA) technology: during assembly the fibre core is actively aligned within micrometre tolerances. Together with the spring-loaded shutter and push-pull latching mechanism this delivers typical insertion loss ≤ 0.1 dB and reliable end face cleanliness even in dusty environments.
Can E-2000 connectors be integrated into existing LC or SC infrastructure?
Yes, via hybrid adapters (E-2000-to-LC, E-2000-to-SC) gradual migration is possible. In practice this is most worthwhile on critical backbone links where low insertion loss delivers the greatest benefit — patch fields with frequent mating typically remain LC/SC.
What are DIAMOND products best suited for?
Critical infrastructure with long service life and high availability requirements: telecom backbones, high-density data centres, industrial automation, railway systems, military and security-critical networks. Wherever additional connector loss accumulates against the link budget.
What does “Fiber Products as authorised production partner” mean specifically?
Two pillars: First, we manufacture modular F4P-own splice systems (1U splice boxes, 3U/4U ODF systems, DIN-rail boxes) in Germany — populated with DIAMOND E-2000 CompactRJ couplings. Second, we distribute the complete DIAMOND original product lines. Since 27.04.2026 we are additionally the central supplier for the 19″ enclosure technology whose in-house production DIAMOND has discontinued.
What warranty applies to Fiber Products systems with DIAMOND components?
We grant a 5-year manufacturer warranty on all F4P splice systems produced in Germany. The DIAMOND components carry their respective DIAMOND specification and ship with 100% inspection certificate.
What inspection certificate do I receive with an ordered DIAMOND pigtail?
Every shipped E-2000 pigtail carries an individual inspection certificate documenting connector end face, tilt angle (max. 0.4°), concentricity (max. 0.25 μm) and final inspection mark. The certificate is accessible via QR code on the connector or through the DIAMOND online shop.
Conclusion: Swiss Precision as an Investment with Long-Term Value
DIAMOND fibre optic technology is not a standard commodity — it is a specialist solution for networks where availability, low insertion loss and serviceability are critical. The Active Core Alignment technology, continuous in-house manufacturing in Losone and the individual inspection certificate for every shipped connector are the substance behind the term “Swiss precision”.
