Amphenol makes fibre Pivot to support AI-scale data centre growth

As increasingly higher-speed optical networks create growing pressure on operators to support more fibre connections in the same infrastructure footprint, Amphenol Network Solutions has launched Pivot, a one rack-unit (RU) fibre distribution panel supporting 192 Lucent Connector (LC) links while maintaining front-access serviceability through a pivoting module design.

The platform is said to be fundamentally designed for a range of deployments where users are balancing density, scalability and ongoing service access.

These include hyperscale AI clusters, telecom central offices, breakout applications and high-density aggregation environments, addressing infrastructure pressures common to both markets: density, scalability, serviceability and migration to higher-speed optical architectures.

The network infrastructure solutions provider said that as artificial intelligence (AI) and cloud applications grow, datacentres need to move more information at faster speeds. That requires significantly more fibre connections, creating new pressure on already-limited rack space. Traditional high-density fibre panels have historically capped out at 144 LC connections per rack unit, often forcing operators to dedicate additional rack space as networks scale.

Pivot is attributed with being able to help solve that challenge by fitting more fibre into a compact 1RU panel without sacrificing service access or maintainability and help datacentres support more connections in the same amount of rack space. Its mid-plane connector architecture becomes accessible through a pivoting front module, placing a forward connector row in front of a recessed centre row.

During maintenance, the front row pivots down to expose the centre row, giving technicians clear access for inspection, cleaning and mating without disturbing adjacent circuits.

Each module is also mounted on a sliding service tray to improve access in dense environments. The design is also claimed to maximise unused cabinet depth in standard four-post racks, enabling higher density without increasing rack footprint.

Key technological features of the system include: 192 LC connections or 96 MPO ports in 1RU; 33% higher density than conventional 144-LC panels; 24 400G/800G circuits per 1RU; what is claimed to be up to 25% rack space savings; pivot-and-slide access for Day-2 maintenance; and support for Base-8, VSFF, 400G/800G networks, 1.6T and 3.2T architectures.

Indeed, as regards the latter, the chassis can support 24 400G/800G circuits in 1RU, compared with 18 circuits in traditional designs, and Amphenol says what previously required four rack units can now be achieved in three.

Moreover, it insists that across a 42U rack, such capability can free up as much as 10U for additional networking, compute, power or other critical infrastructure, helping improve rack utilisation and delay costly infrastructure expansion. It added that in AI and hyperscale applications, this also enables higher MPO8 port counts optimised for AI cluster architectures and simplified breakout architectures.

“Traditional high-density fibre systems have forced operators to choose between density and accessibility,” said Ed Solis, vice-president of global sales and marketing at Amphenol Network Solutions. “Pivot changes that equation by delivering significantly more connectivity per rack unit while still making it practical for technicians to inspect, clean and service connections after deployment.”
