Zero Groundplane Footprint

Side-wall mount utilises PCB gutter space. The 9.5mm × 250mm × 72mm profile preserves the central ASIC heat corridor. Front-to-rear airflow remains completely unobstructed. No thermal blockage. No heat sink interference.

128 F&PMF in 9.5mm

Manages up to 128 single-mode and polarity-maintaining fibers per cassette. Flat ribbon or round cable termination. Bonded ribbon construction with bend radius maintaining design. Polarity is factory-verified and sealed — no field guessing.

150mm, Organised

Up to 150mm overlength management per circuit, contained within the cassette body. No external cable loops. No variable-length cutting in the field. Pre-validated configurations shipped as sealed units.

4×4 or 8×8 Resilience

Optional rail-optimised shuffle layer distributes O/E channels across independent front-panel rails. 4×4 configuration limits single-lane failure to 25% degradation. 8×8 custom configuration limits it to 12.5%. Graceful degradation without ASIC intervention at the fiber layer.
