What Sets the Fusion Box Apart

The Fusion Box sits rigidly in the rack — no sliding mechanism, no movable parts. That makes it lighter, less expensive and more space-efficient than the sliding Future Box. It pays off in environments where:

• Installation is permanent — set and not touched for years
• Rack density is critical — every U counts
• Splicing is done off-site — pigtails arrive pre-terminated and tested
• Budget pressure rules out the Future Box’s sliding mechanism

The Nine Variants

Fusion Box variants combine three connector options with three pigtail-termination states, giving nine configurations:

Connector	Description	Typical Use
E-2000® SX (Simplex)	One coupling per slot, single-fibre	Standard FTTH, telecom backbones
E-2000® CompactRJ (Duplex)	Two couplings per slot, duplex pairs	Data centre patching, high-density
Mixed configurations	Combination of SX and CompactRJ in one chassis	Mixed-purpose distribution racks

Each connector option is available in three states: empty (couplings only, customer pre-terminates), partially populated (some pigtails factory-terminated), or fully populated (all pigtails factory-terminated, ready to splice on incoming fibres).

Connector System: E-2000® Standard

All Fusion Box variants use DIAMOND E-2000® couplings in standard colour-coded geometry:

• Singlemode APC (green) — recommended default for FTTH and high-availability backbones
• Singlemode PC (blue) — for legacy infrastructure
• Multimode (OM3, OM4, 62.5 μm) — for campus and in-building networks

Active Core Alignment (ACA) technology delivers typical insertion loss ≤ 0.1 dB. The push-pull latch with spring-loaded shutter prevents end-face contamination — critical in dust-prone environments.

Factory-Terminated Pigtails

When ordered with factory-terminated pigtails, each fibre arrives ready to splice on the incoming cable side. The factory side is pre-mated to the E-2000® coupling, measured, and the test certificate is available via QR code on the unit.

This pre-termination approach is the typical workflow for high-volume installations: the installer’s onsite work reduces to splice-only — no field connectorisation, no field polishing, no field measurement.

Quality Assurance

Every Fusion Box ships with individual pigtail measurement — not sample inspection. Per-pigtail documentation includes end-face quality, tilt angle (≤ 0.4°), concentricity (≤ 0.25 μm) and final inspection mark. Certificates accessible via QR code or shop.diamond.de.

Available Through Fiber Products

Following the DIAMOND press release of 27 April 2026, Fiber Products GmbH is the central supplier for the DIAMOND 19″ enclosure technology, including the Fusion Box. DIAMOND continues to manufacture all connector components in Losone; Fiber Products handles DACH supply, configuration and F4P-built custom alternatives.

How to Choose Fusion Box vs Future Box

• Choose Fusion Box when the installation will not be reconfigured during the lifecycle and density matters
• Choose Future Box when you anticipate maintenance, splicing access or expansion
• Both use the same E-2000® system — components are intermateable, training is identical
