Connectivity Solutions Direct (CSD), a supplier of cable assemblies and network solutions for today’s demanding enterprise markets, has broken new ground in the fiber optic connectivity space with n+1. This suite of housings and cassettes would enable industry-leading patch-field density of 96 duplex LC or MPO ports per rack unit.

The n+1 platform received US Patent number 10,514,518 for ‘Dense Optical Termination and Patching Platforms, Systems and Methods’ on December 24, 2019 and is in field trials today. Connectivity Solutions Direct’s innovation would bring is a 33 percent improvement in port density when compared with conventional high-density fiber solutions.

Available from CSD today, the n+1 platform components are a new and unique solution to the challenge of making more optical connections in the same amount of space.

Modular Design

The CSD n+1 platform is a modular solution that supports all popular deployments of 8-fiber, 12-fiber, 16-fiber, and 24-fiber MPO pre-terminated trunking, as well as splicing and field termination options. Available in 1RU, 2RU and 4RU housings, the platform’s modular design would enable easy migration to and from duplex to parallel connectivity, even allowing both within a common housing if desired.

“Today’s hyperscale data centers must handle more and more connections, but floor space is fixed, so higher-density connectivity solutions are required,” said Kevin Twomey, President and CEO of CSD. “Our n+1 platform delivers 33 percent more connections per rack unit to address this pressing need.”


Two interchangeable cassettes serve as the building blocks for the CSD n+1 platform. The modular design provides flexibility and functionality without sacrificing density. 8- and 12-port cassettes can be deployed within the same n+1 housing, and even on the same internal tray, without any reduction in port density.

These unique cassettes feature interchangeable adapters and internal components allowing cassettes to be configured for Conversion, Patching, Splicing, Taps, Splitters or Fanouts. Connectivity Solutions Direct’s n+1 platform features standards-based cabling and n+1 internal cassette polarity. The same cassette is used at both ends of the link; cassette or patch cord flipping is not required.
