Meet ever-increasing bandwidth demands with scalable 400G network speed solutions

Download White Paper

400GB Network Speed

Many hyperscale data centers are beginning to make the jump to a 400G fabric as high bandwidth and capacity demands continue to grow. New applications such as machine-to-machine learning, virtual reality, 5G, and online gaming are accelerating the transition to new types of fiber connectivity protocols and media.

 AFL Hyperscale offer a range of cabling and connectivity options for 400G data center deployments.

The below examples all use single-mode fiber, due to its bandwidth and transmission distance capabilities, with a mixture of MPO (either BASE-8 or BASE-16 deployment) and LC/SN connector-based assemblies that can be used with 400G transceivers.

SN Connector-Based Connectivity

The most commonly used connector types in the industry today are LC and MPO. The introduction of a new connector type, namely the SN connector, is set to have a profound impact on 400G.

The SN interface has already been adopted in transceiver specifications of QSFP-DD and OSFP. These transceivers are the new specifications for the next generation of pluggable transceivers for 200Gbps, 400Gbps, and 800Gbps data center interconnects (DCI).

The SN connector is a new, duplex optical fiber connector that uses LC-style 1.25mm O.D. Zirconia ferrules, designed for the next generation Hyperscale, Edge, Enterprise, or Colocation data centers. The SN connector provides superior optical performance while reducing the typical number of connection points in the optical path.

The SN connector was designed to provide individual and independent duplex fiber breakout at a quad-style transceiver (QSFP, QSFP-DD & OSFP) that is more efficient, reliable, and scalable than the MPO connector. The SFP-DD has also adopted the SN as their independent duo-style interface, mainly for wireless front-haul applications.

Beyond transceiver interfaces, SN increases and improves the fiber density and capacity for the existing fiber optic cassettes and patch panels. Compared to the LC connector, SN provides 3 times higher density. This will further support the implementation of more fibers without adding new rack units.

Below are some examples of how the new SN connector can be utilized in 400G hyperscale networks.
