What is the difference between CS and SN fiber connectors

What is the difference between CS and SN fiber connectors

With the ever-increasing demand for higher network bandwidth, data centers have embraced the widespread adoption of 100Gb backbones and are now rapidly transitioning to even faster speeds like 200Gb, 400Gb and more higher speeds in hyper-scale data centers. In response to this evolving landscape, SENKO Advanced Components has developed new specifications for CS and SN fiber optic connectors that can accommodate a greater number of duplex optical fiber links. These next-generation, high-density fiber optic connectors are designed to support data rates of up to 400Gb/s. In this article, we will explor their features, benefits, and applications in modern networking environments.

CS Fiber Optic Connector Basics


The CS fiber connector, also known as Very Small Form Factor (VSFF), is a compact and cost-effective solution that maximizes space utilization in high-density environments. CS fiber connector’s key feature is the ability to support a higher number of duplex optical links, making it ideal for data centers seeking to upgrade to faster transmission speeds. With its 1.25mm ceramic ferrule and LC-like end-face geometry, the CS fiber connector ensures compatibility with various equipment and devices. The CS fiber optic connector offers increased density, improved airflow, and user-friendly installation, making it an excellent choice for space-saving and high-speed applications.

SN Fiber Optic Connector Basics


The SN fiber connector, specifically designed for high-speed data center applications, provides enhanced density and optimized airflow. Similar to the CS fiber connector, the SN fiber connector supports a greater number of duplex optical links, catering to the demands of hyper-scale data centers transitioning to higher data rates. With its dual-ferrule configuration and push-pull tab mechanism, the SN fiber connector achieves improved density, ease of use, and secure connections. It excels in optimizing optical fiber density and handling large data traffic volumes, contributing to efficient data transmission within data center environments.

Difference Optical Cable Compatibility Between CS and SN Fiber Connector


While both CS and SN fiber optic connectors offer high-density solutions for data center, there is notable difference between the two:

The difference in cable compatibility between the CS and SN fiber optic connectors is an important consideration for network professionals. While the CS fiber connector accommodates both 2.0mm and 3.0mm optical cables, providing flexibility for various applications, the SN fiber connector is specifically designed for use with a 1.6mm and 2.0mm optical cable. This distinction becomes particularly relevant in co-located or enterprise data centers that rely on point-to-point connections between different racks. In such scenarios, certain applications may require the use of thicker optical cables, which would be better suited for the CS fiber connector. By offering compatibility with a wider range of optical cable diameters, the CS fiber connector ensures that diverse connectivity needs can be met without compromising performance or efficiency.


Conclusion


CS and SN fiber optic connectors have emerged as next-generation solutions for high-density, high-speed networking applications. With their ability to support a greater number of duplex optical links and compatibility with faster data rates, these fiber optic connectors cater to the evolving needs of data centers and other networking environments. By understanding the features, benefits, and applications of CS and SN fiber optic connectors, network professionals can make informed decisions when selecting the right solution for their fiber optic patch cable requirements.
