Because size matters...
SENKO’s SN connector is a Very Small Form Factor (VSFF) duplex optical connector designed for termination of single-mode and multi-mode fiber cables up to 2.0mm in diameter. The SN connector is manufactured using the same proven 1.25mm ferrule technology as the industry-standard LC connector, but with significantly reduced outer dimensions. This reduced footprint rewards network operators with a three-fold increase in packing density across all of their passive and active hardware.

What the industry is saying

“We are excited to announce the release of both CS and SN duplex adapter tips for our flagship FIP-500 fully automated fiber inspection scope. These new dual fiber tips will help our hyperscale customers rapidly inspect these high-density, very small form factor connectors to ensure error-free transmission at 400G and beyond”.
Nicholas Cole, Enterprise and Data Center Solution Manager EXFO
What the industry is saying

“We are excited about our Licensing Agreement with SENKO on the SN connector which will provide our Hyperscale customers with a new connector form, fit, and function to enable data transmissions of 400G and beyond. With the new SN connector, Hyperscale customers can easily link individual duplex fiber connectors into QSFP-DD & OSFP transceivers, providing high-density, efficient installation and cost-effective deployment.”
Robert Dennelly, Director of Engineering & Product Management at AFL
