SN UPC to LC UPC Duplex OS1 Fiber Optic Patch Cord

The SN connector is the ultimate Base-2 connector combining ‘best-in-class’ packing density with carrier-grade performance and reliability.

Tags: SN Connector, LC Duplex Connector, Very Small Form Factor (VSFF) Connector

SN connector is designed and optimized for next-generation data rates, the SN connector offers network operators the chance to densify their existing legacy infrastructure whilst at the same time providing an upgrade path to 400G and beyond. The SN Standard connector is suitable for termination to either 1.6 mm or 2.0 mm round cable that incorporates a ruggedized jacket and internal strain relief. The SN Standard connector has an integrated ‘push-pull’ boot that simplifies insertion and removal of the connector even in dense patch panels where finger access is limited. A gang-clip can be added to four individual SN connectors allowing them to be patched simultaneously to either adapters or 4-channel (8 fibers) transceivers (subject to product selection).

Features

• Meets IEC random mating Grade B

• Very Small Form Factor (VSFF) connector, 3 x fiber cabling density over Duplex LC

• Unique push-pull boot for simple installation and removal

• Optimized for 400G data rates with QSFP-DD, OSFP and SFP-DD transceivers

• Up to 4 x SN connectors per transceiver

• Direct transceiver breakout in spine/leaf architectures

• Combines two 1.25 mm ceramic ferrules

• Easy identification of the connector alignment key

What is an SN® Connector?

SENKO SN® connector is a next-generation Very Small Form Factor (VSFF) duplex optical connector, tailored for terminating single-mode and multimode fiber cables up to 2.0mm in diameter. Utilizing the established 1.25mm ferrule technology found in the industry-standard LC connector, the SN® connector distinguishes itself with substantially reduced outer housing dimensions. This compact design offers network operators a three-fold increase in packing density across both passive and active hardware. Additionally, unlike previous generations of LC and SC connectors known for their horizontal orientation, the SN® connector features a vertical mount, enhancing flexibility and space utilization in network configurations.

In addition to the duplex SN® connector, SENKO has developed a quadruple duplex SN® connector, housing 8fibers within a single connector body, named the SN® Uniboot. The SN® Uniboot represents a ground breakingadvancement of the Very Small Form Factor (VSFF) Fiber Optic connectors, enabling the simultaneous gangingof four duplex SN® into one SN® Uniboot connector in a single unit. This innovation provides the same level ofconnectivity as an MPO 8-fiber connector, eliminating the requirement for breakout cassettes or fanout cablesto transition from Base-8 to Base-2. This dual functionality makes theSN® Uniboot ideal for duplex server connections, optimizedfor high-density trunks, and perfectly compatible withhigh data rate transceivers utilizing four opticallanes (8-fibers).
