The SN series is a ceramic-based, very small form factor (VSFF) duplex optical connector designed for high-density fiber optic applications. It supports single-mode and multi-mode fibers up to 2.0mm in diameter and is compatible with 200G, 400G, 800G, and even 1.6TB transceivers. Its compact design allows for a three-fold increase in packing density compared to standard LC connectors, which is critical in supercomputing centers where space and airflow are limited .
While standard SN connectors are optimized for high-density and high-speed data transmission, high-temperature variants can be engineered using ceramic ferrules and polymeric inserts to withstand elevated operating temperatures. Comparable high-temperature connectors from other manufacturers, such as TE Connectivity's DTMH series, operate up to +150°C, and CONEC's high-temperature connectors can endure 8,000 hours at +125°C and 2,000 hours at +150°C . These materials and designs ensure thermal stability, minimal signal loss, and mechanical reliability under continuous high-temperature operation.
Supercomputing centers require connectors that can handle:
SN connectors can be used in Base-2 or Base-8 configurations, allowing direct connection to next-generation transceivers without additional cassettes or fan-outs. This reduces network complexity, improves airflow, and enhances cooling efficiency, which is critical in supercomputing centers where thermal management is a priority . Additionally, the ceramic-based construction ensures long-term reliability even under repeated mating cycles and high-temperature conditions.
For supercomputing centers, high-temperature resistant SN connectors provide a combination of high-density fiber connectivity, thermal stability, and support for ultra-high-speed data transmission. By leveraging ceramic ferrules, polymeric inserts, and compact VSFF designs, these connectors meet the demanding requirements of modern HPC environments, ensuring reliable, high-performance interconnects in thermally challenging conditions .
