SN? Fiber Optic Connector

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, reliable, and 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.

The miniature design allows higher installation density in ODF optical cabinets and multiple parallel transmission in optical transceivers to increase transmission speed.

The SN optical connector is especially suitable for use in optical transceivers and comes in two basic versions:

• Connector for patchcords - connecting cables, usually 2.0 mm in diameter.
• Connector for pigtails, fibers 0.9 mm, for splicing fibers from optical cables in ODF optical cabinets.

A number of adapters with a capacity of 2-12 optical fibers can be used for the interconnection between patchcords and pigtails in optical distribution frames.

The SN connector for 0.9 mm fiber is available in two basic variants, SN Junior and SN Compact. The mutual compatibility of these variants and different types of adapters is shown in the diagram:
