The SN® connector is a new duplex optical fiber connector designed for Data Center 400G optimization. The SN® connector was designed to provide individual and independent duplex fiber breakout at a quad style transceiver (QSFP, QSFP-DD, OSFP) as a more efficient, increased reliability, and a lower cost alternative than the MPO connector. SN® has two LC style 1.25 mm diameter zirconia ferrules in a single housing, pitched 3.1 mm apart vs 6.25 mm in a duplex LC connector.
The SN® connector supports up to 2.0 mm jacketed cable
Features and advantages of SN connector:
- Effective size reduction compared to LC Duplex
- Designed for OSFP/QSFP-DD Break out application
- Proven 1.25 mm ferrule technology
- 4 duplex connectors (total 8-fibers) in OSFP/QSFP-DD footprint
- 2.0 mm duplex jacketed cable
- IEC random mating Grade B
